2019 eBird Taxonomy Update—COMPLETE

By Team eBird August 21, 2019
Black-rumped Flameback Dinopium benghalense

The 2019 eBird taxonomy update is COMPLETE. At this stage, all major taxonomic changes should be complete. Thank you for your patience.

We do this update once each year, taking into account the past 12 months’ worth of recent taxonomic knowledge on splits, lumps, name changes, and changes in the sequence of the species lists. Your eBird Mobile should have had an “Updating taxonomy…” message that loaded the new version. Search the “full taxonomy” for Swinhoe’s White-eye or Blue-throated Hillstar to confirm that your taxonomy has updated. If you see unfamiliar bird names in the lists as the changes percolate through our system, please refer to the story below to understand the change and why it happened.

If you only have time to take two things away from the taxonomy update, here they are:

  1. We automatically update your records for you when possible, using known range, your checklist comments, and other information to assign records to a species. However, please review your lists (made simple by the “my records” links below). After the publication of this story, most species should be in the process of changing and these changes should be mostly resolved in a few days. If you need to correct anything, it’s super easy using “Change Species.”
  2. If you use eBird Mobile on iPhone or Android, please check the App Store or Google Play Store to make sure you have the latest version of the app. After you’ve updated to the new taxonomy (you should see an “Updating Taxonomy…” notification appear when you start the app up) make sure to submit a list from a *new* location near you (i.e., not one of your stored “recent locations”). This step will ensure that the local checklist filter is updated to the newest version and that all your post-update submissions have the correct new entries, such as African Sacred Ibis or Madagascar Sacred Ibis instead of the pre-update “Sacred Ibis.”

2019 eBird Taxonomy Update

This year’s update is v2019 of the eBird/Clements Checklist. The eBird/Clements Checklist is an integrated global taxonomy for the birds of the world, including all species and subspecies, as well as additional taxa useful to field birders to report in eBird. The list of species available in eBird is the eBird Taxonomy (v2019) and includes all species, subspecies groups (which we call identifiable sub-specific forms or ISSF), hybrids, intergrades, spuhs (e.g., scoter sp.), slashes (e.g., Short-billed/Long-billed Dowitcher), domestics, and forms. The Clements Checklist includes only species and subspecies, along with subspecies groups which are further identified as monotypic (consisting of one subspecies) or polytypic (consisting of more than one subspecies). Read more about the eBird Taxonomy.

A list of all the taxonomic changes is below. Most changes for the AOS-NACC Sixtieth supplement to the American Ornithological Society’s Check-list of North American Birds are incorporated, as well as AOS-SACC revisions to the South American Check-List through 6 June 2019.

The taxonomic statistics of the final v2019 eBird/Clements taxonomy are:

species    10721
subspecies    17991
slash    709
group (polytypic)    1339
group (monotypic)    2461
spuh    653
hybrid    462
domestic    15
form    122
intergrade    31
TOTAL TAXA:    34504

Since this is a long article, here is a short index:


When the taxonomy is updated in eBird, many changes are fairly simple to implement. When a common name changes, a scientific name changes, or when the taxonomic sequence is revised, those changes roll through and quickly appear in eBird output fairly quickly. Staying on top of name changes is a challenge, and consulting Avibase is one of the best ways to keep track. Just type any bird name in Avibase to see the history of that name, and—if it differs from eBird—it will show what the eBird equivalent is for that name. Try it with “Louisiana Heron”, for example.

When species are ‘lumped’ (e.g., two taxonomic entities that used to be considered separate species, but are now one), eBird usually retains the former species as an identifiable group. In these cases, your records may shift to the lumped form and your totals may (or may not) drop by one. The actual entity that you observed and reported has not changed in any way other than being changed from species to subspecies. For example, this year, those who have birded Central America may notice that your previous reports of Orange-bellied Trogon Trogon aurantiiventris and Collared Trogon Trogon collaris have changed to Collared Trogon (Orange-bellied) Trogon collaris aurantiiventris and Collared Trogon (Collared) Trogon collaris collaris.

When splits occur, the process is more complicated. In most cases, we have had subspecies options available for reporting in anticipation of the split. All these records update automatically to the new species. When a bird is reported at the broader species level (without a subspecies listed on your entry), and then that species is split, we update the records in eBird to one of the “daughter” species whenever possible. We try to be very conservative with this. When two species do not overlap in range (i.e., they are allopatric) we go ahead and make the change. When the species do overlap (i.e., are sympatric), and do not have clear seasonal or habitat differences, we usually do not make the change. This results in your records being left as the more conservative “slash” option.

As an example, this year Black-faced Ibis Theristicus melanopis is split into two species: Black-faced Ibis Theristicus melanopis and Andean Ibis Theristicus branickii. The former occurs in southern South America and the Pacific coast of Peru while Andean Ibis occurs at higher elevations in the southern half of Peru, northwestern Bolivia, and in an isolated area of Ecuador. The two are similar but easily identifiable with good looks and are treated in most field guides. In many areas there is only one species (e.g., all are Black-faced Ibis in Argentina), but in northern Chile and parts of Peru both species are possible. In those areas the records would be converted to Black-faced/Andean Ibis Theristicus melanopis/branickii since we won’t be able to tell which species you observed (unless you noted the subspecies in your eBird submission). As always in eBird, when you are unsure, your observation is best listed as the slash option.

If you want to review your records of “Black-faced/Andean Ibis” or of “Short-billed/Long-billed Dowitcher”, there are a couple ways to do this through the My eBird tools. If you know the checklist it is on, you can find the list in “Manage My Observations” and edit it as needed. If you can find your checklist on the range map of “Black-faced/Andean Ibis” then you can just click on the marker for your list and open it from there. But the best option to review your records is to go to My eBird and then click “Download My Data” from the right side. This downloads your entire eBird database as a CSV file that can be opened in Excel or a similar spreadsheet program. From there, you should easily be able to sort by name or search for “Black-faced/Andean Ibis” to find your records. Then you can scroll to the correct date or just replace the Submission ID in the URL for a checklist view.

This year’s update has a lot of changes, with most of those from Southeast Asia (especially Indonesia, New Guinea, and the South Pacific) and Africa, because of a thorough review of avian taxonomy for those regions. Almost all of these changes also improve alignment with other global taxonomies: the IOC World Bird List and Handbook of the Birds of the World/Birdlife International taxonomies already recognized most of the below splits, so we move ever closer to a unified and agreed-upon global list of birds. We look forward to the day when there is more agreement about species limits and less confusion about different taxonomic treatments between different global authorities on the world’s birds.


We provide birds names in eBird for more than 30 languages, as well as 25 additional regional versions of some languages. For example, Pluvialis squatorola is known as Black-bellied Plover in our taxonomy, but known by its winter dress in some areas such as the United Kingdom, where it’s called Grey Plover. You can access name preferences under “Preferences” from most eBird pages, which is also where you can set the names to shows as common names or scientific names. One option is English (IOC), which gives a full translation of species names into the IOC World Bird List (v8.2) nomenclature. Note that these names are exact taxonomic matches, so they reflect as slashes when a species is split by IOC and not by eBird; similarly, species split by eBird will appear as subspecies groups for IOC. Our Common Name Translations article explains more about regional common name preferences.


The species below were split in eBird. To see a map of the new species, click “map.” Previously we included links to a media gallery, but with the recent release of eBird species pages, the links this year go directly to that page (and from that page, you can easily access the media gallery). To see your personal lists in My eBird, just make sure you are logged in and click “My Records.” If you have seen the species but don’t have any records shown, then please enter your sightings!  We encourage all birders to carefully review the below splits and check your personal records and to update them if you think we made an error.

Below are the splits for this update:

Stejneger’s (top) and White-winged Scoter are best separated in male plumage, when White-winged has distinctive brown flanks and a “bumpy” head shape with a concave slope broken up by a knob at the base of the bill. Stejneger’s Scoter has black flanks, an angular “hooked” knob at the bill base (it has sometimes been known as the Hook-billed Scoter), yellow “lips” at the edge of the tip of the bill, and a formidable sloping head shape. Photos by Pavel Parkhaev/Macaulay Library (upper) and Joshua Covill/Macaulay Library (lower).

White-winged Scoter (Melanitta deglandi) is split into two species: White-winged Scoter Melanitta deglandi, which occurs in North America, and Stejneger’s Scoter Melanitta stejnegeri, which occurs in eastern Asia. Last year we split Velvet Scoter Melanitta fusca; this year our revision follows the AOS, which also splits these three taxa that were once considered the three subspecies of Melanitta fusca.

We know of only one place on the planet where both species are known to occur regularly, the Gambell seawatch! If you have records from there, you will need to find those lists and parse them to the correct species manually. Vagrant White-winged Scoter may occur in East Asia and western Europe, and vagrant Stejneger’s reach western Europe and have two records so far from the Lower 48 states in USA (Montana and California). So we retain a slash option for conservative reporting:

  • White-winged/Stejneger’s Scoter Melanitta deglandi/stejnegeri [map]

In southeast Asia, Long-billed Partridge Rhizothera longirostrisand Dulit Partridge Rhizothera dulitensis are split; the latter is poorly known and highly endangered from highlands of northeastern Borneo.

In east Africa, Chestnut-naped Francolin Pternistis castaneicollis and Black-fronted Francolin Pternistis atrifrons are split; the latter is extremely rare and poorly known from s Ethiopia and n Kenya.

Tibetan Eared-Pheasant Crossoptilon harmani populations in s Tibet and adjacent ne India are recognized as Tibetan Eared-Pheasant Crossoptilon harmani while those in the remainder of the range in western and southern China and ne India are now known as White Eared-Pheasant Crossoptilon crossoptilon

Madagascar Green-Pigeon Treron australis is split into Comoros Green-Pigeon Treron griveaudi, of Mohéli in the Comoros Islands, and Madagascar Green-Pigeon Treron australis, of Madagascar.

Torresian Imperial-Pigeon Ducula spilorrhoa is split into Yellowish Imperial-Pigeon Ducula subflavescens of the Bismarck Archipelago and Admiralty Islands and Torresian Imperial-Pigeon Ducula spilorrhoa of the Aru Is., New Guinea and adjacent islands and n and ne Australia.

Short-tailed Frogmouth Batrachostomus poliolophus is split into two species, each endemic to different islands in Southeast Asia: Sumatran Frogmouth Batrachostomus poliolophus and Bornean Frogmouth Batrachostomus mixtus

In addition to the recognition of a newly described species of hillstar, we also split Andean Hillstar Oreotrochilus estella in to Green-headed Hillstar Oreotrochilus stolzmanni, occurring in the Andes from s Ecuador to central Peru, and Andean Hillstar Oreotrochilus estella from s Peru to Argentina and Chile.

The widely disjunct range of Steely-vented Hummingbird was curious, so it is probably not surprising to have the Central American population recognized as a new species: Blue-vented Hummingbird. Although the two look very similar, they aren’t actually sister species. Steely-vented and Blue-vented Hummingbirds by Peter Hawrylyshyn/Macaulay Library and Thomas Barbin/Macaulay Library.

Genetic studies showed that, despite phenotypic similarities, the widely-separated populations of Steely-vented Hummingbird Amazilia saucerottei in South America and Central America are not even each other’s closest relatives. They are split as Steely-vented Hummingbird Amazilia saucerottei, from northern Colombia and Venezuela, and Blue-vented Hummingbird Amazilian hoffmanni which occurs from southern Honduras to Costa Rica.

Tristan Moorhen Gallinula nesiotis is split into two island-endemic daughter species: Tristan Moorhen Gallinula nesiotis and Gough Moorhen Gallinula comeri.

Hottentot Buttonquail Turnix hottentottus was a widespread African bird, occurring through much of sub-Saharan Africa. With this year’s split, the widespread form is now known as Black-rumped Buttonquail Turnix nanus while Hottentot Buttonquail Turnix hottentottus is restricted to coastal areas in southernmost South Africa.

Tropical Shearwater Puffinus bailloni was considered a widespread species of warmer areas of the Indian and Pacific Oceans and had multiple different subspecies. With this year’s update the form breeding around Bonin Island, Japan, (and not known to disperse widely away from those islands) is split as a separate species, Bannerman’s Shearwater Puffinus bannermani which is not even the closest relative of Tropical Shearwater Puffinus bailloni. There are lots of difficult to identify small Puffinus shearwaters globally (many of which have recently been split) and this year makes seabirding even more challenging and fun.

Since these species almost overlap, we retain the slash option for individuals of uncertain identity.

  • Bannerman’s/Tropical Shearwater Puffinus bannermani/bailloni [map]

Making small shearwater identification even more challenging (and fun?), a distinctive subspecies of Little Shearwater Puffinus assimilis is split as Subantarctic Shearwater Puffinus elegans. Little Shearwater is mostly restricted to waters around Australia and northern New Zealand, while Subantarctic occurs around New Zealand, southern Africa, and southern South America.

As always with seabirds, acknowledging uncertainty in identification is often prudent, so we retain a Little/Subantarctic option:

  • Little/Subantarctic Shearwater Puffinus assimilis/elegans [map]

South American birders have long paid attention to the two forms of Black-faced Ibis, which are distinctive in shape and plumage and usually separate out by habitat. Andean Ibis is a highland species that is shorter-legged, has less prominent white in the wings, and just a small black area of skin at the base of the bill, while Black-faced occurs mostly in lowland areas and has longer legs, more white in the wings visible in flight, and a distinctive black wattle. The two may occur in the same area (same flocks even) in parts of Peru and Chile though, so careful separation is important. Andean (left) and Black-faced Ibis by Jacob Drucker/Macaulay Library and Dominic Garcia-Hall/Macaulay Library.

Two similar South American ibises have subtle plumage and structural differences and segregate fairly completely by range and habitat. Formerly lumped as Black-faced Ibis Theristicus melanopis, these are now segregated as Black-faced Ibis Theristicus melanopis and Andean Ibis Theristicus branickii

We know of a couple areas in n Chile and s Peru where both species occur together, so please be cautious about identifications in those regions as well as in areas where neither species is regular, and we have a slash option to allow for that conservative reporting.

  • Black-faced/Andean Ibis Theristicus melanopis/branickii [map]

African Sacred Ibis Threskiornis aethiopicus is split into African Sacred Ibis Threskiornis aethiopicus and Madagascar Sacred Ibis Threskiornis bernieri, but note that African Sacred Ibis also occurs in Europe, the Middle East, and Taiwan (where it is introduced) and Madagascar Sacred Ibis also nests in the Seychelles.

Although we aren’t aware of any cases of sympatry (occurring in the same area), ibis move around quite a bit so it seemed prudent to retain a slash option in case a vagrant Sacred Ibis turned up somewhere on an Indian Ocean island and was viewed at a distance too far to assess the iris color, which is the best field mark for separating these two species. Also, African Sacred Ibis is widely introduced, but it might be prudent to identify escapees or introduced birds with care.

  • African/Madagascar Sacred Ibis Threskiornis aethiopicus/bernieri [map]

Barred Honey-buzzard Pernis celebensis is split into Sulawesi Honey-buzzard Pernis celebensis and Philippine Honey-buzzard Pernis steerei, with each occurring where you’d expect: Sulawesi (Indonesia) and the Philippines, respectively.

Eastern Marsh-Harrier Circus spilonotus is a widespread and migratory harrier of east Asia and this year we split the resident population of New Guinea as a separate species, Papuan Marsh-Harrier Circus spilothorax.

Since Eastern Marsh-Harrier is migratory, the two could theoretically co-occur or turn up in an area outside of normal range were conservative reporting would be needed; we retain a slash for these two, just in case:

Reunion Harrier Circus maillardi is split into Reunion Harrier Circus maillardi and Madagascar Harrier Circus macrosceles; the former is restricted to Réunion Island in the Indian Ocean while the latter occurs both on Madagascar and the nearby Comoros Islands.

Two island endemic scops-owls are split from Sulawesi Scops-Owl Otus manadensis and named for their home islands: Siau Scops-Owl Otus siaoensis and Sula Scops-Owl Otus sulaensis.

Like many owls, Southern Boobook and Morepork are very similar visually but have distinctive voices. Expect more splits within Southern Boobook in coming years! Southern Boobook and Morepork by Owen Lishmund/Macaulay Library and Jesse Gibson/Macaulay Library.

Southern Boobook Ninox boobook and Morepork Ninox novaeseelandiae are separated at the species level (formerly known as Southern Boobook Ninox boobook). Southern Boobook is widespread in Australia, New Guinea, Timor, and Indonesia, while Morepork is restricted to Tasmania, New Zealand, and Norfolk Island (a Lord Howe Island subspecies is extinct). We expect more splits in Southern Boobook in the future, since the subspecies groups Southern Boobook (Alor) Ninox boobook plesseni, Southern Boobook (Rote) Ninox boobook rotiensis, and Southern Boobook (Timor) Ninox boobook fusca each probably deserve species status. Stay tuned!

The two can both occur in southern Victoria, Australia, where it seems that some Tasmanian Moreporks (sometimes separated as a species in their own right) seem to move to the mainland in winter. For this reason, we retain a slash option to promote conservative reporting.

Buff-breasted Paradise-Kingfisher Tanysiptera sylvia is split into two species, with Buff-breasted Paradise-Kingfisher Tanysiptera sylvia occurring widely in Australia and New Guinea (some populations migrate from Australia to New Guinea!) while Black-capped Paradise-Kingfisher Tanysiptera nigriceps is restricted to Bismarck Archipelago off eastern New Guinea.

New studies indicate that Indian Roller Coracias benghalensis consists of two species that differ subtly but consistently in plumage: Indochinese Roller Coracias affinis from eastern India (roughly from West Bengal east) through s China, much of Southeast Asia including the Thai-Malay Peninsula, and Indian Roller Coracias benghalensis throughout most of the Indian subcontinent, Sri Lanka, and into the Middle East as far west as Turkey.

Golden-throated Barbet Psilopogon franklinii populations from southern Vietnam and a small corner of adjacent Laos are recognized as a distinct species Necklaced Barbet Psilopogon auricularis.

Black-rumped Flameback Dinopium benghalense is widespread in south Asia and this year the population of southern Sri Lanka is split as Red-backed Flameback Dinopium psarodes.

Please note that both species come in contact, and may hybridize, in northern Sri Lanka so we have these two options as well:

  • Black-rumped/Red-backed Flameback Dinopium benghalense/psarodes [map]
  • Black-rumped x Red-backed Flameback Dinopium benghalense x psarodes [map]

The most significant split in Europe is the recognition of Iberian Green Woodpecker Picus sharpei, which has a distinctive voice and subtle head pattern differences from the widespread Eurasian Green Woodpecker Picus viridis. Iberian Green Woodpecker occurs throughout Portugal, Spain, and Andorra, and ekes into westernmost France in the Pyrenees.

Since the two woodpeckers come in contact in western France and are very similar, especially in quick or distant views, we retain a slash version. Although some of your records may appear as the slash early in the process, we will gradually switch those over to the correct species in all areas except the portions of France where one would have had to specifically identified the subspecies at the time in order to know what species to apply it to (please note that this same philosophy for record conversion is used widely in eBird during taxonomy update time).

  • Eurasian/Iberian Green Woodpecker Picus viridis/sharpei [map]

Rainbow Lorikeet Trichoglossus moluccanus is split into six species as listed below with their ranges:

  • Sunset Lorikeet Trichoglossus forsteni [map] [species page] [my records]
    • Bali, Lombok, Sumbawa (Lesser Sundas), and Tanahjampea and Kalaotoa Islands (Flores Sea)
  • Leaf Lorikeet Trichoglossus weberi [map] [species page] [my records]
    • Flores Island (Lesser Sundas)
  • Marigold Lorikeet Trichoglossus capistratus [map] [species page] [my records]
    • Sumba, Timor and E Lesser Sundas (Wetar and Romang)
  • Coconut Lorikeet Trichoglossus haematodus [map] [species page] [my records]
    • New Guinea and adjacent islands (including some off s New Guinea administered by Queensland, Australia), Bismarck Archipelago, Solomon Islands, Vanuatu,New Caledonia, and Loyalty Islands; introduced and established in Singapore
  • Red-collared Lorikeet Trichoglossus rubritorquis [map] [species page] [my records]
    • norhern Australia from w. Queensland to n. West Australia
  • Rainbow Lorikeet Trichoglossus moluccanus [map] [species page] [my records]
    • Widespread in eastern Australia, including Tasmania; introduced and established around Perth, Western Australia

Although these various lorikeets do not overlap in range, all might be found in captivity and introduced populations occur in some areas. We retain a spuh that could apply to any of the above species (all formerly known as Rainbow Lorikeet) to allow conservative reporting for escapees and other cases of uncertainty.

  • rainbow lorikeet sp. Trichoglossus sp. (rainbow lorikeet complex) [map]

The widespread African species Brown-necked Parrot Poicephalus fuscicollis is split with the recognition of Cape Parrot Poicephalus robustus, restricted to coastal areas of southeastern South Africa. Brown-necked Parrot Poicephalus fuscicollis occupies the remainder of the wide range in sub-Saharan Africa.

Socorro Island is a small, remote island off the west coast of Mexico that is renowned for its endemism, so it should come as no surprise that the parakeet there, previously considered as subspecies of Green Parakeet Psittacara holochlorus has always deserved recognition as its own species, now known as Socorro Parakeet Psittacara brevipes.

The extent of species-level diversity in Brazil is far from completely known. One of the latest splits, supported by genetics and voice, is the separation of Ceara and Lesser Woodcreepers. Ceara and Lesser Woodcreepers by Yuri Raia/Macaulay Library and Eden Fontes/Macaulay Library.

Northeasterly populations of Lesser Woodcreeper Xiphorhynchus fuscus are now recognized as Ceara Woodcreeper Xiphorhynchus atlanticus, which occurs in the Brazilian state of Ceara and several adjacent states.

Highland Elaenia Elaenia obscura is split into two species, Highland Elaenia Elaenia obscura from the Andes of s Ecuador to n Argentina and Small-headed Elaenia Elaenia sordida in se Brazil, extreme nw Argentina (e.g., Misiones), and Paraguay. The two are widely separated by range, though Argentina listers can get both.

Sierran Elaenia Elaenia pallatangae is split into two species, not considered sister taxa. Tepui Elaenia Elaenia olivina, occurs in the tepui region of se Venezuela, s Guyana and n Brazil, while the Andean species retains the name Sierran Elaenia Elaenia pallatangae and can be found in the Andes from Colombia to Bolivia. If you loved learning the subtle vocal differences among elaenia species, then South American birding just got even more fun for you!

These two take the award, hands down, for the most striking and beautiful birds of this taxonomic update. Even their bowers are beautiful, if you agree with the female bowerbirds that bright blue pieces of litter are beautiful. They also represent New Guinea, which has more than its fair share of splits with this update. Flame (left) and Masked Bowerbirds by Nick Athanas/Macaulay Library and Arco Huang/Macaulay Library.

Two striking bowerbirds from New Guinea are split as the former Flame Bowerbird Sericulus ardens is divided into Flame Bowerbird Sericulus ardens, of lowland and foothill areas in southern New Guinea and the Masked Bowerbird Sericulus aureus of southern New Guinea mountains (Toricelli and Prince Alexander mountains)

Black-faced Friarbird Philemon moluccensis is split into Buru Friarbird Philemon moluccensis, endemic to Buru Island, and Tanimbar Friarbird Philemon plumigenis, which occurs on the Tanimbar Islands on Larat and Yamdena and in the Kai Islands on Kai Kecil and Kai Besar.

Rufous Fieldwren Calamanthus campestris is split into a widespread Rufous Fieldwren Calamanthus campestris found across much of Australia and a range-restricted Western Fieldwren Calamanthus montanellus restricted to just the southwestern corner of Western Australia.

In New Guinea, Dimorphic Jewel-babbler Ptilorrhoa geislerorum of eastern New Guinea, which is distinctive for its brownish female plumage as well as voice and elevation, is split from the more widespread Blue Jewel-babbler Ptilorrhoa caerulescens in which males and females are not sexually dimorphic.

These two species come into close contact so we also have a slash option for cases of uncertainty; if you see a male of either species or a female Ptilorrhoa caerulescens, you may need this option; but if it is a female geislerorum you are in luck–they are uniquely distinctive in color!

From these photos it seems hard to believe that White-bellied and Jerdon’s Minivets were ever considered the same species. Myanmar does not have a large number of endemics, so Jerdon’s Minivet does improve that country’s score on endemics! White-bellied and Jerdon’s Minivets by Balaji P B/Macaulay Library and Michael Hurben/Macaulay Library.

Endemic to the plains of central Myanmar, Jerdon’s Minivet Pericrocotus albifrons had been considered a striking form of White-bellied Minivet Pericrocotus erythropygius but is now recognized as its own species; the range of White-bellied Minivet Pericrocotus erythropygius is now restricted to India.

The two distinctive subspecies groups of Ashy Cuckooshrike Coracina cinerea are now split as different species, with Madagascar Cuckooshrike Coracina cinerea restricted to Madagascar and Comoros Cuckooshrike Coracina cucullata found only on Grand Comoro and Mohéli in the Comoros archipelago between Madagascar and mainland Africa.

Varied Sittella Daphoenositta chrysoptera is split into an Australian species, which retains the name Varied Sittella Daphoenositta chrysoptera and a species endemic to New Guinea now known as Papuan Sittella Daphoenositta papuensis.

In perhaps the most surprising taxonomic revision for this update, subspecies melanorhyncha, previously classified as a subspecies of Little Shrikethrush Colluricincla megarhyncha (in the group Little Shrikethrush (Arafura) Colluricincla megarhyncha [megarhyncha Group]), in fact is a whistler (Pachycephala)So the genus was not even right! Correcting this taxonomic issue, we now recognize melanorhyncha as a species, Biak Whistler Pachycephala melanorhyncha.

Variable Pitohui Pitohui kirhocephalus has undergone a three-way split with all the new species still occurring in New Guinea and adjacent islets: Northern Variable Pitohui Pitohui kirhocephalus occurs across much of northern New Guinea while Southern Variable Pitohui Pitohui uropygialis occurs across much of southern New Guinea, including the westernmost end known as the Vogelkop (“Bird’s Head) Peninsula. Raja Ampat Pitohui Pitohui cerviniventris, known also as the Waigeo Pitohui (e.g., by Birdlife/HBW) is the most range-restricted, occurring only on the Papuan Islands off the west tip of the Vogelkop Peninsula, including Waigeo, Gemien, Sagewin and Batanta islands.

in Africa, the Black-headed Batis Batis erlangeri is divided in the Western Black-headed Batis Batis erlangeri, which is widespread in Africa from Eritrea and Ethiopia south and west to se. Nigeria and Cameroon and south to n. Angola and extreme nw. Tanzania. The Eastern Black-headed Batis Batis minor has a range mostly hugs the coast from southern Somalia to Tanzania.

African drongos are heavily revised and split with this update (see “Complicated splits and shuffles below”. Among the simpler changes, Velvet-mantled Drongo Dicrurus modestus is split into Fanti Drongo Dicrurus atactus and Velvet-mantled Drongo Dicrurus modestus.

These species may come in contact, and are virtually identical (although genetic reveal they for distinct evolutionary lineages), so reporting as the slash may be prudent in some areas:

A northwestern population of Black-throated Shrikebill Clytorhynchus nigrogularisis recognized as Santa Cruz Shrikebill Clytorhynchus sanctaecrucis, endemic to the Santa Cruz island group in the eastern Solomon Islands, while the name Black-throated Shrikebill Clytorhynchus nigrogularisis retained for the birds living on the larger islands in Fiji.

Slender-billed Crow Corvus enca is widespread in southeast Asia, occurring in the Philippines, the southern Thai-Malay Peninsula, and throughout much of Indonesia. A highly range-restricted population is split as Violet Crow Corvus violaceus, which can be found only in the southern Moluccas on Seram, Buru and Ambon islands.

In addition to their distinct geographic ranges, North Island and South Island Robins are quite distinct in plumage. South Island and North Island Robins by Cameron Eckert/Macaulay Library and Jason Vassallo/Macaulay Library

The New Zealand Robin South Island Robin Petroica australis is now recognized to involve two species: North Island Robin Petroica longipes which occurs on New Zealand’s North Island and South Island Robin Petroica australis in the south.

Pacific Robin Petroica pusilla is fairly widespread in the south Pacific, but the population on Norfolk Island has always stood out as having a distinctive plumage. It is now split as Norfolk Robin Petroica multicolor and is no longer thought to be most closely related to Pacific Robin.

Blanford’s Lark Calandrella blanfordi has the distinction of being both lumped and split with this update. We formerly recognized Erlanger’s Lark Calandrella erlangeri, from the highlands of Ethiopia, but that is now lumped within Blanford’s Lark (and retained as a subspecies group). At the same time, Rufous-capped Lark Calandrella eremica–the population from the Arabian Peninsula–is recognized as a species. With these changes, Blanford’s Lark Calandrella blanfordi is now found in Somalia and Ethiopia.

Stierling’s and Miombo Wren-Warblers by Marna Buys/Macaulay Library and Peter Steward/Macaulay Library.

Miombo Wren-Warbler Calamonastes undosus is split into two species: Miombo Wren-Warbler Calamonastes undosus and Stierling’s Wren-Warbler Calamonastes stierlingi.

Both species are widespread but are similar in the field and their ranges come close to touching or even may overlap slightly, so we retain a slash option to promote conservative reporting when uncertainty exists.

Green-backed Camaroptera Camaroptera brachyura is a well-known and widespread African bird. With this update we split the highly range-restricted population on the escarpment in s. Gabon and n. Angola as Hartert’s Camaroptera Camaroptera harterti withGreen-backed Camaroptera Camaroptera brachyura   remaining throughout the rest of the species’ wide range in sub-Saharan Africa.

Since these species are nearly or actually parapatric (ranges are adjacent), we retain a slash option for conservative reporting.

Bar-throated Apalis Apalis thoracica is split into four species, three of which are highly range-restricted: Taita Apalis Apalis fuscigularis is endemic to the Taita Hills of Kenya; Yellow-throated Apalis Apalis flavigularis occurs in extreme se. Malawi east of the Nyasa-Shire Rift, and parts of adjacent Mozambique; Namuli Apalis Apalis lynesi is even more range-restricted, known only from Namuli Mountain in Mozambique; while Bar-throated Apalis Apalis thoracica is widespread in the southeastern quadrant of Africa, occurring from s. Kenya to South Africa.

Chestnut-throated Apalis Apalis porphyrolaema with the recognition of Kabobo Apalis Apalis kaboboensis as a distinct species restricted to mountain forest around Mt. Kabobo in the democratic Republic of Congo, while Chestnut-throated Apalis Apalis porphyrolaema is more widespread in mountain forests of Uganda, Kenya, and Tanzania.

As if Cisticola identification was not already challenging enough, Winding Cisticola Cisticola marginatus is split into five species. Fortunately, these five mostly separate out cleanly by range: Ethiopian Cisticola Cisticola lugubris is endemic to Ethiopia and the only “Winding Cisticola” found there; Coastal Cisticola Cisticola haematocephalus occupies coastal areas from Somalia south to n. Tanzania; Luapula Cisticola Cisticola luapula is centered on sw Africa, from n and ne Namibia, e Angola, se Democratic Republic of the Congo, Zambia (except the northeast), n Botswana, and nw Zimbabwe; Rufous-winged Cisticola is centered on se Africa, from s Malawi, Mozambique, and extreme se Zimbabwe to s Mozambique and the east coast of South Africa. Finally, the bird that retains the name Winding Cisticola Cisticola marginatus is one widespread through west Africa (Senegal to Nigeria) and east through sub-Saharan Africa to central Sudan, w Ethiopia, and n Uganda and south to central and e Democratic Republic of the Congo, n Zambia, Malawi and Mozambique.

Ethiopian and Rufous-winged are pretty well separated from the others, but we have a slash that covers potential overlap in the remaining species:

In Southeast Asia, the Tawny Grassbird Cincloramphus timoriensis is split into Papuan Grassbird Cincloramphus macrurus, which is widespread in New Guinea except for the southern coastal plain. The other species retains the name Tawny Grassbird Cincloramphus timoriensis., is also found on New Guinea (but restricted to the southern coastal plain in Papua, Indonesia and the country of New Guinea), northern and eastern Australia, the Philippines, and also occurs throughout much of Indonesia.

Eastern Mountain-Greenbul Arizelocichla nigriceps is split into four species: Eastern Mountain Greenbul Arizelocichla nigriceps which is widespread in the forests of central Africa from northern Tanzania and the Democratic Republic of Congo to Uganda and w Kenya; Uluguru Mountain Greenbul Arizelocichla neumanni of the Uluguru Mountains in northern Tanzania; Yellow-throated Mountain Greenbul Arizelocichla chlorigula of the Nguru Mountains and highlands of Iringa District in eastern Tanzania; Black-browed Mountain Greenbul Arizelocichla fusciceps of the mountains of sw Tanzania, ne Zambia, Malawi and ne Mozambique. If you go to Tanzania and hit all four corners of the country you can find all four species!

There is one other change to the taxonomy of Eastern Mountain Greenbul though, since subspecies kungwensis, previously included within the group Eastern Mountain Greenbul (Mountain) Arizelocichla nigriceps [nigriceps Group], instead belongs with Shelley’s Greenbul Arizelocichla masukuensis and is added to the group Shelley’s Greenbul (Kakamega) now known as Arizelocichla masukuensis kakamegae/kungwensis. This subspecies is restricted to western Tanzania in the Mount Kungwe area, which is pretty remote, so the chances are good that this won’t affect your eBird lists much!

Orange-spotted Bulbul Pycnonotus bimaculatus is one of many species of songbird highly imperiled by the rampant songbird trapping in Indonesia (see this article from Birdlife International, for example) and has been a Sensitive Species in eBird, but we now have two heavily trapped species to worry about with the split of Aceh Bulbul Pycnonotus snouckaerti, of western Sumatra, from Orange-spotted Bulbul Pycnonotus bimaculatus of eastern Sumatra, Java, and Bali.

Ashy Bulbul Hemixos flavala is split, with Cinereous Bulbul Hemixos cinereus representing the birds of the southern Thai-Malay Peninsula (north to Surat Thani in Thailand), Sumatra, and Borneo, and the birds from the Himalaya to Indochina, including much of the rest of Thailand, retaining the name Ashy Bulbul Hemixos flavala. Only in Thailand can you find both species and the ranges are well-separated in Thailand as well.

Rwenzori Hill Babbler Sylvia atriceps is split from African Hill Babbler Sylvia abyssinica. African Hill Babbler is patchily distributed in forests of east Africa from Ethiopia to Malawi and Mozambique, with isolated populations in Angola, on Mt. Cameroon, and on Bioko Island in the Gulf of Guinea; Rwenzori Hill Babbler does not overlap in range, but occurs in both forests of western Uganda, eastern Democratic Republic of Congo, Rwanda and Burundi as well as in w Cameroon and s Nigeria.

Abyssinian White-eye Zosterops abyssinicus is split into two species: Abyssinian White-eye Zosterops abyssinicus is the more northerly one, occurring on the Arabian Peninsula and also n Sudan, Eritrea, and much of Ethiopia; Pale White-eye Zosterops flavilateralis occurs from se Ethiopia and extreme sw Ethopia s through Somalia and much of Kenya to central Tanzania.

Broad-ringed White-eye Zosterops poliogastrus is split into six species. Below are their ranges:

  • Mbulu White-eye Zosterops mbuluensis [map] [species page] [my records]
      • SE Kenya (Chyulu Mts.) and n Tanzania (North Pare Mts.)
  • Taita White-eye Zosterops silvanus [map] [species page] [my records]
      • SE Kenya (Taita Hills)
  • South Pare White-eye Zosterops winifredae [map] [species page] [my records]

      • N Kenya (Mt. Kulal)
  • Kikuyu White-eye Zosterops kikuyuensis [map] [species page] [my records]

  • Kilimanjaro White-eye Zosterops eurycricotus [map] [species page] [my records]
      • N Tanzania (Mt. Kilimanjaro, Mt. Meru and Arusha regions)

and, as we often do, in case conservative reporting is needed we have retained an option for that:

In Southeast Asia, Short-tailed Scimitar-Babbler Napothera danjoui is split from the Myanmar endemic Naung Mung Scimitar-Babbler Napothera naungmungensis.

Mount Victoria (left) and Chinese Babax by Ayuwat Jearwattanakanok/Macaulay Library and Dave Curtis/Macaulay Library.

Mount Victoria Babax Ianthocincla woodi nearly makes another Myanmar endemic, since it only occurs on the slopes of Mount Victoria in sw Myanmar, but a few birds sneak into the Lushai Hills of Assam, India. Otherwise, Chinese Babax Ianthocincla lanceolata remains widespread in central and southern China and in n and central Myanmar.

Vocal differences reveal that Chattering Gnatwren Ramphocaenus sticturus, of Amazonian Peru, w Brazil, and n Bolivia is a distinct species that has a strong preference for bamboo. Its song is quite distinctive and totally unlike Long-billed Gnatwren, with a chatter followed by some loud musical notes. Long-billed Gnatwren could be known as Trilling Gnatwren, which might help keep the calls straight if you have a chance to tick off both of these species. Long-billed Gnatwren Ramphocaenus melanurus occurs from s Mexico south through much of the rest of the northern half of South America, and has a lot of subspecific diversity that could also deserve further study.

Since contact zones are not well understood, some gnatwrens should be reported as a slash, especially if they are not heard or audio recorded:

Recent genetic work reveals that the two allopatric (widely separated) populations of White-lored Gnatcatcher represent different species: Yucatan Gnatcatcher Polioptila albiventris only on the coast of the Yucatan Peninsula (and a Mexico endemic) and White-lored Gnatcatcher Polioptila albiloris in dry forests from Michoacán and Guerrero, Mexico, south to Costa Rica.

Guianan Gnatcatcher Polioptila guianensis is split into four species, with their ranges below:

  • Guianan Gnatcatcher Polioptila guianensis [map] [species page] [my records]
    • The Guianas (Guyana, Suriname and French Guiana) south to the Amazon
  • Inambari Gnatcatcher Polioptila attenboroughi [map] [species page] [my records]
    • western Amazonian Brazil south of the Amazon, and west of the Madeira River
  • Rio Negro Gnatcatcher Polioptila facilis [map] [species page] [my records]
    • S Venezuela (Amazonas) to extreme ne Brazil (upper Rio Negro)
  • Klage’s Gnatcatcher Polioptila paraensis [map] [species page] [my records]
    • eastern Amazonian Brazil south of the Amazon, and east of the Rio Madeira

We retain two slash options to cover gnatcatchers with uncertain identities:

The Scaly Thrush Zoothera dauma complex has gone through quite a bit of taxonomic revision recently, including the split of White’s Thrush Zoothera aurea, Nilgiri Thrush Zoothera neilgherriensis and Sri Lanka Thrush Zoothera imbrica recently. We continue that trend, and align with othert taxonomies (e.g., IOC and Birdlife/HBW) in recognizing Amami Thrush Zoothera major as distinct from Scaly Thrush Zoothera dauma. Amami Thrush can be found on Amami-O-Shima in n Ryukyu Islands of Japan.

Three very similar South American thrushes are split this year, in part because of revelations that populations of Black-billed Thrush Turdus ignobilis the co-occur (i.e., are sympatric) without interbreeding. There is still much to be learned about these three species now that their status as distinct species is more widely recognized. Pantepui Thrush Turdus murinus occurs in Guyana and se Venezuela, while Campina Thrush Turdus arthuri is endemic to white sands forest, a distinct habitat in Amazonia, in much of the same range extending to se Colombia and central Amazonian Brazil, from the east bank of the Rio Madeira to the east bank of the Rio Tapajós. Black-billed Thrush Turdus ignobilis is a bit more widespread, and is the only form to occur west of the eastern Andes in Colombia. It also ranges well south through nw Brazil, e Peru and n Bolivia.

We retain two slash options to account for uncertain identification of birds in areas of sympatry:

White-tailed Alethe Alethe diademata, ranging in west Africa from Senegambia to Togo is split from Fire-crested Alethe Alethe castanea which occurs from S Nigeria through Cameroon to Gabon and east to n and central Democratic Republic of the Congo, sw South Sudan, w Uganda, and extreme nw Tanzania (also on Bioko).

Although they don’t overlap in range, focus on the extent or orange color below to separate Tickell’s and Indochinese Blue Flycatchers. The genus Cyornis contains some of the tricker species to identify in east Asia and Southeast Asia, and some more splits are expected in the near future. Stay tuned! Tickell’s (left) and Indochinese Blue Flycatchers by Rahul Singh/Macaulay Library and Tim Avery/Macaulay Library.

Tickell’s Blue Flycatcher Cyornis tickelliae is split into Tickell’s Blue Flycatcher Cyornis tickelliae and Indochinese Blue Flycatcher Cyornis sumatrensis. Tickell’s occurs mostly on the Indian subcontinent, east to Bangledesh, n Myanmar, and Yunnan, China while Indochinese occurs from Myanmar to Vietnam and south through Thailand and Malaysia to ne Sumatra, Indonesia.

Three monotypic groups, previously included in White-browed Shortwing Brachypteryx montana, now are recognized as separate, monotypic species: Himalayan Shortwing Brachypteryx cruralis; Chinese Shortwing Brachypteryx sinensis; and Taiwan Shortwing Brachypteryx goodfellowi. See below for ranges:

Himalayan and Chinese may overlap, or come close, so we retain a slash for uncertain records:

As adult males Persian and Kurdish Wheatears are very distinctive, but immature plumages can be a major ID challenge. Please check your records carefully in the Middle East, since both species occur together in migration and winter and some will have been left as the slash option–Kurdish/Persian Wheatear–if the identification was not clear by range and date. Persian (left) and Kurdish Wheatears by Oded Ovadia/Macaulay Library and Christoph Moning/Macaulay Library.

Other taxonomies have long considered the two subspecies of Red-tailed Wheatear Oenanthe xanthoprymna to be species in their own right and we follow suit this year. Kurdish Wheatear Oenanthe xanthoprymna occurs from se Turkey through the mountains of s Iran and winters in eastern Egypt (in the Nile Valley and near the Red Sea), northeastern Sudan, and on the western Arabian Peninsula, locally also in southern Israel. It has a distinctive male plumage with an extensive black throat, but females can be tough to separate from both sexes of Persian Wheatear Oenanthe chrysopygia, which breeds from breeds from ne Turkey, s Armenia, Azerbaijan, and Iran east to s Turkmenistan, s Tajikistan (Pamir range), Afghanistan, and extreme nw Pakistan; it winters from the southern Arabian Peninsula and southern Iraq east to Pakistan and northwestern India. Persian Wheatear is sometimes known as Afghan Wheatear.

Females of Kurdish look almost identical to Persian Wheatears, and the two do occur out of range as vagrants and overlap in some areas in migration and winter, so we retain a slash option for conservative reporting:

  • Kurdish/Persian Wheatear (Red-tailed Wheatear) Oenanthe xanthoprymna/chrysopygia [map]

Brown-throated Sunbird Anthreptes malacensis and  Gray-throated Sunbird Anthreptes griseigularis are split. Brown-throated is widespread in Southeast Asia, occurring from S Myanmar to peninsular Thailand, Indochina, Sumatra and s Borneo, as well as on many islands in Indonesia. Gray-throated is limited to the Philippines, but Brown-throated also occurs there, although the two do not tend to occur in the same areas. Gray-throated is on Luzon, Mindoro, Catanduanes, Samar, Leyte, Sakuyok, Camiguin Sur, and ne Mindanao while Brown-throated is on Cebu, Masbate, Negros, Panay, Sibuyan, Tablas, Romblon, Ticao, Basilan, w and central Mindanao, Talicod, Mapun, Balabac, Culion, Palawan and Calauit, Sibutu, and Sitanki.

We do retain a slash for areas where the two may come in contact or the local population is uncertain:

  • Brown-throated/Gray-throated Sunbird Anthreptes malacensis/griseigularis [map]

Miombo Sunbird Cinnyris manoensis is split into Western Miombo Sunbird Cinnyris gertrudis and Eastern Miombo Sunbird Cinnyris manoensis which segregate by range. Western Miombo Sunbird occurs from Central Angola to se Democratic Republic of the Congo and w Zambia while Eastern Miombo Sunbird occurs from s Tanzania to se Zambia, Zimbabwe and n Mozambique, as well as on Mt. Gorongoza. Mozambique.

The two may overlap, so we retain a slash option, just in case:

  • Western/Eastern Miombo Sunbird Cinnyris gertrudis/manoensis [map]

Eastern Double-collared Sunbird Cinnyris mediocris is split into three species as follows:

  • Eastern Double-collared Sunbird Cinnyris mediocris [map] [species page] [my records]
      • Highlands of Kenya and n Tanzania
  • Usambara Double-collared Sunbird Cinnyris usambaricus [map] [species page] [my records]
      • Highlands of se Kenya (Taita Hills) and ne Tanzania
  • Forest Double-collared Sunbird Cinnyris fuelleborni [map] [species page] [my records]
      • Highlands of Tanzania to Malawi, ne Zambia and n Mozambique

Red-headed Fody Foudia eminentissima is split with the recognition of Aldabra Fody Foudia aldabrana as a single-island endemic on the world’s second largest coral atoll of Aldabra, part of the Outer Islands of the Seychelles. Red-headed Fody is found in the Comoros, including the islands of Grand Comoro, Anjouan, Mohéli, and Mayotte.

Please note also that we have seen lots of erroneous data submissions of Red-headed Fody from the main islands of the Seychelles. All of these birds must refer to introduced populations of Red Fody Foudia madagascariensis so we will be making this correction to existing eBird submissions as well. Please be careful with your eBird submissions here!

Swee Waxbill Coccopygia melanotis is split with the recognition of a disjunct westerly population as Angola Waxbill Coccopygia bocagei, which gives Angola another endemic species. Swee Waxbill Coccopygia melanotis can be found in Zimbabwe, South Africa, Lesotho, and Eswatini (formerly Swaziland).

In our taxonomy, Desert Sparrow Passer simplex previously had two highly disjunct subspecies groups. These are now recognized as separate species, with Zarudny’s Sparrow Passer zarudnyi in deserts of Uzbekistan and Tajikistan and Desert Sparrow Passer simplex widespread in the deserts of north Africa.

Blue Chaffinch Fringilla teydea was known from two islands in the Canaries, but these are now each recognized as single-island endemics: Tenerife Blue Chaffinch Fringilla teydea and Gran Canaria Blue Chaffinch Fringilla polatzeki, further highlighting the important and vulnerable biodiversity on islands.

Golden-winged Grosbeak Rhynchostruthus percivali is split into two species, Arabian Grosbeak Rhynchostruthus percivali which is widespread on the Arabian Peninsula and Socotra Grosbeak Rhynchostruthus socotranus which is endemic to Socotra Island.

Streaky-headed Seedeater Crithagra gularis is split into West African Seedeater Crithagra canicapilla from Guinea to the Central African Republic, South Sudan, ne Democratic Republic of the Congo, n Uganda, and extreme w Kenya and Streaky-headed Seedeater Crithagra gularis, from Angola and Zambia south to South Africa.


Fork-tailed Drongo Dicrurus adsimilis is split into two species. One species, Glossy-backed Drongo Dicrurus divaricatus, is based on the monotypic group Fork-tailed Drongo (Glossy-backed) Dicrurus adsimilis divaricatus. There are two genetic lineages within divaricatus, however. Revise the range of nominate divaricatus from “southwestern Mauritania, Senegal, and Gambia east to northern Cameroon, Chad, Central African Republic, northern Democratic Republic of the Congo, southern Sudan, South Sudan, Ethiopia, Eritrea, Somalia, northern Uganda, and northern Kenya” to “southwestern Mauritania south to Guinea, east to southeastern Niger and northeastern Nigeria (Lake Chad)”. The name lugubris, previously considered to be a junior synonym of divaricatus, now is applied to the populations from “southwestern Chad (Lake Chad) east to Ethiopia, Eritrea, and Somalia, south to northern Democratic Republic of the Congo, northern Uganda, and northern Kenya”. The second species, Fork-tailed Drongo Dicrurus adsimilis, contains the subspecies apivorus, jubaensis (newly recognized), fugax, and adsimilis. Subspecies jubaensis, previously not recognized, has range “Ethiopia, Eritrea, and Somalia”.

Square-tailed Drongo Dicrurus ludwigii is split into three species (one of which is newly described). Subspecies sharpei, with range “Senegal to northwestern Angola, northern Democratic Republic of the Congo, southern South Sudan, Uganda and western Kenya”, represents two distinct lineages. The western lineage is described as a new species, Western Square-tailed Drongo Dicrurus occidentalis with range “Senegal to Nigeria (west of the Niger River)”. The populations in the remainder of the range of sharpei are recognized as Sharpe’s Drongo Dicrurus sharpei, with range “central Africa, from Nigeria (east of the Niger River, south of the Benue River) east to Uganda, South Sudan, and western Kenya, and south to northwestern Angola and southeastern Democratic Republic of the Congo”.

With all this complexity, these two options will probably be needed:

Asian Zosterops have undergone a comprehensive, extensive, and confusing (make that, confusing as as hell!) reorganization. Much of this is based on several studies that include an extensive genetic phylogeny for the taxa in south and east Asia. Here’s a quick and dirty attempt to summarize and simplify:


Big reorganization here! Here’s the recipe for the new species:

  1. Mix the full population of Mountain White-eye Zosterops montanus, which used to be a Philippine endemic, in a large mixing bowl with the full population of Japanese White-eye Zosterops japonicus.
  2. Add a heaping tablespoon, accounting for the full population of the Indonesian endemic Enganno White-eye Zosterops salvadorii
  3. Carefully separate the subspecies williamsoni (southern Thailand and east coast of northern and central Thai-Malay Peninsula) from the remainder of the Oriental White-eye population. Add to the mix.
  4. Then take the birds from coastal forests of the western and southeastern Thai-Malay Peninsula, Sumatra, the Riau Islands, Bangka, and the Natuna Islands, and coastal western Borneo. Slap the name erwini on those birds.
  5. Mix thoroughly.
  6. Divide the mixture, which we’ll call Zosterops japonicus based on the the rules of nomenclatural priority, roughly in half based on range. Bake for millenia and you have:
    1. One species, Warbling White-eye Zosterops japonicus, centered on Japan and the Philippines (including Palawan), including southernmost Sakhalin Peninsula of Russia, most of the Japanese islands, and certain Indonesian islands including the Ternate, Bacan and Seram (Moluccas), central and S Sumatra, Java, Bali, Sulawesi, Sula Is., Buru, Lombok, Sumbawa, Flores, Timor, S Sumatra.
    2. Another other (partially migratory) species ranging across much of eastern China (including Hainan Island), Taiwan, ne. Vietnam, and the former range of Enggano White-eye which includes Enggano and Mega islands (off w Sumatra), as well as coastal areas of Thailand, Malaysia, and Borneo (areas formerly thought to have the species Oriental White-eye Z. palpebrosus…but see below). The new name for this species is Swinhoe’s White-eye Zosterops simplex
    3. Almost done. But wait, there is one fleck in there that doesn’t belong. Is it an eggshell? Fish out the subspecies gilli, endemic to Marinduque (Phillippines) and formerly part of Mountain White-eye, and we are going to add that to the existing species Lowland White-eye Zosterops meyeni. They were actually the same thing. Who knew?

Your new species in Japan, the Philippines (all of the former Mountain White-eye subspecies), and much of Indonesia is:

and the one in China, Taiwan, ne. Vietnam, and coastal habitats in Thailand, Malaysia, and Borneo is, including the Enggano White-eye locales, is:

and, with gilli synonymized with meyeni:



Not much simpler with Oriental White-eye Zosterops palpebrosus. Here’s the recipe for that one:

  1. Two subspecies of Everett’s White-eye Zosterops everetti don’t really belong with that species. We’ll start our recipe in a small side bowl with subspecies wetmorei and tahanensis, occurring in “southern Thailand and the northern Thai-Malay Peninsula” and “southern Thai-Malay Peninsula”, respectively.
  2. Add two subspecies from Oriental White-eye that are basically the same ingredient as the two subspecies above–auriventer (a poorly known for from s. Myanmar, after we split erwini from it above!) and medius (Borneo).
  3. Bake and give the new name Hume’s White-eye Zosterops auriventer to this new mixture.

Then start on what’s left of Oriental White-eye Zosterops palpebrosus. We’ve already removed auriventer (and erwini), medius, and williamsoni, representing coastal populations in Thailand, Malaysia, and Borneo. We split what’s left into different into a few different species.

  1. Pull out subspecies melanurus and buxtoni, from Java, Sumatra (?), and Bali and split those as Sangkar White-eye Zosterops melanurus
  2. There is one contaminant left in the dish. Subspecies unicus, previously classified as a subspecies of Zosterops palpebrosus , is closely related to Ashy-bellied White-eye Zosterops citrinella. Transfer to that species.
  3. Everything that remains can be clumped in the same species. Give this species a new name, reflecting its more restricted range: Indian White-eye Zosterops palpebrosus

So for this one, take Oriental White-eye, without williamsoni or populations we named erwini above. Split melanurus and buxtoni as:

A couple slashes are prudent here too:

  • Hume’s/Swinhoe’s White-eye Zosterops auriventer/simplex [map

Here’s the formal list of the new species, with subspecies and ranges; the subspecies with an asterisk have undergone a name change because of reorganization under a different species; all the below species are reconstituted, but the ones that have a change to the English name associated with the scientific name have two asterisks

Identification of introduced white-eye populations is somewhat tentative and incompletely known at this stage. If more than one taxon had been released in an area, it might need genetics or a very astute birder to figure it out. Based on current knowledge, our best understanding is:

Hawaii – These white-eyes are thought to be Z. j. japonicus, so the name for Hawaii changes from Japanese White-eye Zosterops japonicus to Warbling White-eye Zosterops japonicus.

Southern California (2006 to present) – White-eyes released in Costa Mesa, Orange county, California have spread rapidly and occur to Ventura and San Diego Counties now and may continue to spread. Based on one specimen so far, we believe these refer to Zosterops simplex simplex, and thus change from Japanese White-eye Zosterops japonicus to Swinhoe’s White-eye Zosterops simplex with this update. These are expanded rapidly and we will be surprised if they are not soon added to the official Califronia and United states list as a fully established exotic.

Southern California (1970s and 1980s) – White-eyes released and briefly established near Balboa Park, San Diego, were considered Oriental White-eye Zosterops palpebrosus and number of extant specimens. These were never considered established because they were eradicated before they could be established (since exotic white-eyes are known to be a pest species). The are thought to refer to nominate palbebrosus, which is now part of Indian White-eye Zosterops palpebrosus.

So the United States has records of exotic/introduced white-eyes of three species now.


In one more attempt to help this all make sense, or for those who don’t like cooking, below is a chart of how your records may have changed by country:

  • If you had reported Japanese White-eye Z. japonicus from Russia, Japan, South Korea, Taiwan, Indonesia, or Hawaii, USA, those records will now show as Warbling White-eye Zosterops japonicus
  • If you had reported Japanese White-eye (Z. japonicus) from China, Hong Kong, Taiwan, Vietnam, Laos, Cambodia, Myanmar, or Thailand, or introduced populations from California, USA* or Singapore, those records will now show as Swinhoe’s White-eye Zosterops simplex [* note – California records from San Diego County from prior to 2006 pertain to Indian White-eye Z. palpebrosus).
  • If you had reported Mountain White-eye Z. montanus from anywhere, it will now show as Warbling White-eye (Zosterops japonicus)
  • If you had reported Oriental White-eye Z. palpebrosus) from anywhere west of Thailand (e.g., India, Bhutan, Nepal, Pakistan, Myanmar, Bangladesh etc.) those will now appear as Indian White-eye Z. palpebrosus.
  • If you had seen Oriental White-eyes Z. palpebrosus) in mangrove or coastal habitat in s. Thailand, s. Myanmar, Malaysia, Singapore, Sumatra, or on Borneo, those will now appear as Swinhoe’s White-eyes Z. simplex. Note that these birds have a yellow ventral stripe, while inland, migratory Swinhoe’s do not.
  • If you had Oriental White-eye from Java, Sumatra (inland areas, not coastal ones), or Bali, then those are now Sangkar White-eye Z. melanurus melanurus
  • If you had reported Everett’s White-eye Z. everetti from either of two popular parks in Thailand–Khao Yai NP or Kaeng Krachan NP–these will now appear as Hume’s White-eye Zosterops auriventer, as will any others from peninsular Thailand, Malaysia, Singapore, or Borneo. Please note also that many observers also seem to have reported Oriental White-eye Z. palpebrosus from those areas; it was only recently discovered (in 2004, see the paper here) that subspecies wetmorei was the predominant white-eye in Khao Yai (other than Chestnut-flanked) and no other similar species have been found in either area before or since. Because of this, we have converted all reports of Oriental White-eye to Hume’s White-eye from those areas as well.
  • If you had any of the following:
    • Any Oriental White-eyes from Sumbawa and Flores in the Lesser Sundas, this would be subspecies unicus, which is now moved to Ashy-bellied White-eye Z. citrinella
    • Any sightings of Enggano White-eye Z. salvadorii then these are now Swinhoe’s White-eye Z. simplex.
    • Mountain White-eye from Marinduque (Phillippines), then these are subspecies gilli which is now Lowland White-eye Z.

Note that inherent in all the above changes is an assumption that the eBirder identified his or her white-eye correctly in the first place. In this and ALL cases for this taxonomy update, we hope that birders will check their records, add documentation where needed, and be able to vouch for their records as they move through a taxonomic update. In the end, eBird counts on eBirders to curate your own bird records.

These are some of the toughest identifications on the planet, and the reorganization above shows how wrong we all could have been for so long. Please review your Asian white-eyes and change them as needed. Opt for conservative reporting options like Indian/Swinhoe’s White-eye or even Zosterops sp. (covering the whole genus) if you are unsure or there seems to be any doubt in what is known, especially in areas of overlap between Indian White-eye and Swinhoe’s White-eye. Be sure to check out an excellent ID article on Warbling (ssp. japonicus) vs. Swinhoe’s (ssp. simplex) by Nial Moores of Birds Korea, who is also on our review team for the Koreas.



In eBird’s taxonomic revisions, lumps are very easy to deal with. Usually the taxa become subspecies groups, so there is no changing of records necessary, just a recalculation of lists as the species drop to identifiable subspecies. Whenever possible, we encourage birders to continue reporting at the subspecies level, but whenever you select these options, be sure you understand the taxa that you are using; do not try to guess at the subspecies based on the name! This section also includes invalid species descriptions: these are rare but occur when an original description of a species or subspecies is proven to be a hybrid, rare variant, or other form of natural variation that does not represent a species. Full details for can be seen at the Clements Updates & Corrections page.

A vocal analysis helped to clarify that Chaco Nothura Nothura chacoensis, described from the chaco habitat of nw Paraguay, is not really distinctive at the species level and is demoted to Nothura maculosa chacoensis, a subspecies of Spotted Nothura Nothura maculosa. We don’t even consider it distinctive enough to retain as an identifiable subspecies group.

The extinct Norfolk Pigeon Hemiphaga spadicea is lumped with the extant New Zealand Pigeon Hemiphaga novaeseelandiae. The two are retained as identifiable subspecies groups, even if your chance to identify a New Zealand Pigeon (Norfolk) in the field sadly has long since passed.

    • New Zealand Pigeon (New Zealand) Hemiphaga novaeseelandiae novaeseelandiae [map]

Two subtly different gulls, the Red-billed Gull Chroicocephalus scopulinus and Silver Gull Chroicocephalus novaehollandiae are lumped as a single species known as Silver Gull Chroicocephalus scopulinus. The two are retained as identifiable subspecies groups, but as is the case with many subspecies of gulls, the two are barely identifiable and only the extreme “larophiles” claim they can separate them reliably.

  • Silver Gull Chroicocephalus novaehollandiae [map] [species page] [my records]
    • Silver Gull (Silver) Chroicocephalus novaehollandiae novaehollandiae/forsteri [map]
    • Silver Gull (Red-billed) Chroicocephalus novaehollandiae scopulinus [map]

Crested Hawk-Eagle Nisaetus cirrhatus and Changeable Hawk-Eagle Nisaetus limnaeetus are now lumped as Changeable Hawk-Eagle Nisaetus cirrhatus, which brings our taxonomy into alignment with other global authorities such as the IOC and HBW/Birdlife. The two former species are retained as identifiable subspecies groups.

  • Changeable Hawk-Eagle Nisaetus cirrhatus [map] [species page] [my records]
    • Changeable Hawk-Eagle (Crested) Nisaetus cirrhatus cirrhatus/ceylanensis [map]

In a long-anticipated lump, the Orange-bellied Trogon Trogon aurantiiventris is merged with Collared Trogon Trogon collaris. It is retained as an identifiable subspecies group, since its more orangey belly is distinctive even if there is little else that sets it apart. Collared Trogon subspecies groups are revised slightly as well (subspecies extimus is moved from the “Bar-tailed” group to the “Collared” group and the more restricted Bar-tailed group is now known as Xalapa.

  • Collared Trogon Trogon collaris [map] [species page] [my records]
    • Collared Trogon (Xalapa) Trogon collaris puella
    • Collared Trogon (Orange-bellied) Trogon collaris aurantiiventris/underwoodi [map]
    • Collared Trogon (Collared) Trogon collaris [collaris Group]

Although we recently split them in 2014, Gold-whiskered Barbet Psilopogon chrysopogon and Gold-faced Barbet Psilopogon chrysopsis are again lumped as Gold-whiskered Barbet Psilopogon chrysopogon, although both are retained as identifiable subspecies groups.

Three species of Epinecrophylla, now known as Stipplethroats (formerly just one of the many “antwrens”), are lumped as Rufous-backed Stipplethroat now. Here are there former names Rio Negro Antwren Epinecrophylla pyrrhonota, Yasuni Antwren Epinecrophylla fjeldsaai, and Rufous-backed Antwren Epinecrophylla haematonota. All are recognized as identifiable subspecies groups still.

  • Rufous-backed Stipplethroat Epinecrophylla haematonota [map] [species page] [my records]
    • Rufous-backed Stipplethroat (Rio Negro) Epinecrophylla haematonota pyrrhonota
    • Rufous-backed Stipplethroat (Yasuni) Epinecrophylla haematonota fjeldsaai
    • Rufous-backed Stipplethroat (Rufous-backed) Epinecrophylla haematonota haematonota

As noted above under “Splits”, Erlanger’s Lark Calandrella erlangeri is lumped into Blanford’s Lark Calandrella blanfordi even as Rufous-capped Lark is split from Blanford’s.

  • Blanford’s Lark Calandrella blanfordi [map] [species page] [my records]

    • Blanford’s Lark (Erlanger’s) Calandrella blanfordi erlangeri [map]

The taxonomy of the Lesser Whitethroat complex has been complicated and unsettled. This year is no exception. With this update, three previously-recognized species are now lumped within Lesser Whitethroat Sylvia curruca: Desert Whitethroat Sylvia minula; Margelanic Whitethroat Sylvia margelanica; and Hume’s Whitethroat Sylvia althaea. The below subspecies groups match the taxa formerly recognized as species in our taxonomy

  • Lesser Whitethroat Sylvia curruca [map] [species page] [my records]
    • Lesser Whitethroat (Lesser) Sylvia curruca curruca/blythi/halimodendri [map]
    • Lesser Whitethroat (Desert) Sylvia curruca minula [map]
    • Lesser Whitethroat (Gansu) Sylvia curruca margelanica [map]
    • Lesser Whitethroat (Hume’s) Sylvia curruca althaea [map]

But since we also had some additional slash options for conservative reporting, these have taken on some fairly complicated names to help keep straight what taxa are possibly involved with each option:

  • Lesser Whitethroat (curruca/blythi) Sylvia curruca curruca/blythi
  • Lesser Whitethroat (halimodendri) Sylvia curruca halimodendri
  • Lesser Whitethroat (Lesser/Desert) Sylvia curruca curruca/minula
  • Lesser Whitethroat (Desert/Gansu) Sylvia curruca minula/margelanica
  • Lesser Whitethroat (Lesser/Hume’s) Sylvia curruca curruca/althaea
  • Lesser Whitethroat (Lesser/Desert/Hume’s) Sylvia curruca curruca/minula/althaea

Whew! Good luck if you try to sort your Lesser Whitethroats by subspecies!

Enggano White-eye Zosterops salvadorii is embedded within what now is recognized as Swinhoe’s White-eye Zosterops simplex (see complicated splits and lumps above). We no longer recognize it as an identifiable form, so it is now reduced to a subspecies of Swinhoe’s White-eye as Zosterops simplex salvadorii. See Swinhoe’s White-eye above for more info.

The Lord Howe White-eye Zosterops tephropleurus is now considered to be “just” a subspecies of Silvereye Zosterops lateralis, now Zosterops lateralis tephropleurus. It is not even considered distinctive enough to be retained as an identifiable subspecies group, so is addition to the loss of a Lord Howe Island endemic the main result is a tiny expansion in the range of Silvereye to include Lord Howe Island.

The former species Kivu Ground-Thrush Geokichla tanganjicae is now lumped within Abyssinian Ground-Thrush Geokichla piaggiae, but the two forms are retained as identifiable subspecies groups.

The former species African Scrub-Robin Cercotrichas minor is now lumped within Rufous-tailed Scrub-Robin Cercotrichas galactotes, but the two forms are retained as identifiable subspecies groups.

  • Rufous-tailed Scrub-Robin Cercotrichas galactotes [map] [species page] [my records]

    • Rufous-tailed Scrub-Robin (African) Cercotrichas galactotes minor/hamertoni [map]

We formerly recognized three species of Quailfinch: Black-faced Quailfinch Ortygospiza atricollis, Black-chinned Quailfinch Ortygospiza gabonensis, and African Quailfinch Ortygospiza fuscocrissa. These are all now lumped under a single species, but the forms are retained as identifiable subspecies groups.

African Pipit is widespread and diverse, with 13 subspecies divided among four subspecies groups in the eBird taxonomy (try searching “ANCI” , the four-letter code for the scientific name for this species, on the eBird Species Maps). This year we lump Jackson’s Pipit Anthus latistriatus as a 14th subspecies and fifth group in African Pipit.

The former species Damara Canary Serinus leucolaemus is now lumped within Black-headed Canary Serinus alario, but the two forms are retained as identifiable subspecies groups.

  • Black-headed Canary Serinus alario [map] [species page] [my records]
    • Black-headed Canary (Black-headed) Serinus alario alario [map]
    • Black-headed Canary (Damara) Serinus alario leucolaemus [map]


Each year, a few newly described species or populations newly recognized for their distinctiveness are named and added to the eBird/Clements taxonomy. This just goes to show how much remains to be learned about the birds of the World! Full details be seen at the Clements Updates & Corrections page.

An interesting new species of Oreotrochilus hillstar was described from Ecuador and ratified as a species by the AOS-SACC. It apparently has a very small range and is believed to be highly imperiled.

In Borneo, Cream-vented Bulbul Pycnonotus simplex has long been known to have variation in eye color, and in Borneo it has been known to have pale-eyed and dark-eyed forms. However, a genetic study of these two forms on Borneo has revealed that one is actually a very distinctive and not particularly closely related species, Cream-eyed Bulbul Pycnonotus pseudosimplex.

NOTE: These records are basically impossible for us to change on your behalf, since the two species overlap and must be identified by eye color. All records are currently left as Cream-vented Bulbul, which is the commoner and more widespread species. Please help us by changing your records to the correct form, adding notes about the eye color and habitat for each, and changing to our slash form when appropriate:

  • Cream-vented/Cream-eyed Bulbul Pycnonotus simplex/pseudosimplex [map]

In Indonesia, the Rote Leaf Warbler was previously recognized as an undescribed species, but is now ratified as Rote Leaf Warbler Phylloscopus rotiensis.


A few miscellaneous errors, including typos from 2018, revisions to our understanding of populations in certain areas, and other issues deserve special mention. We explain each below.

Based on a couple of genetic studies, it is now known that the Falkland Islands just have one species of steamer-duck. Since that species includes birds capable of flight and others that cannot fly, it had been thought that both Falkland Steamer-Duck (flightless) and Flying Steamer-Duck (flighted) occurred there. However, the genes reveal that this species is perhaps in the process of losing the ability to fly, with some birds still able to fly and others that do not. As a result, all steamer-duck records from the falklands are now ascribed to Falkland Steamer-Duck Tachyeres brachypterus.

When Ruddy Duck and Andean Duck were split last year, we failed to revise the common and scientific names for the slash option that is useful in southern South America. This of course was intended for cases where you can’t tell if you saw an Andean Duck or Lake Duck, since the two overlap in range and are very similar; Ruddy Duck is a North American species that does not overlap in range and doesn’t really resemble Lake Duck anyway!

  • Ruddy/Lake Duck Oxyura ferruginea/vittata –> Andean/Lake Duck Oxyura andina/vittata [map]

We are never happy about it, but we do make occasional typos in our taxonomy update. One of these was listing a New Zealand hybrid as Pied x Variable Oystercatcher Haematopus longirostris x unicolor when we always intended for it to refer to occasional instances of hybridization between South Island Oystercatcher Haematopus finschi x unicolor and Variable Oystercatcher Haematopus unicolor. Check out the records of these hybrids on the map. We have that typo fixed now.

    • South Island x Variable Oystercatcher (hybrid) Haematopus finschi x unicolor [map]

The slash Bianchi’s/Marten’s WarblerPhylloscopus valentini/omeiensis always should have included the very similar Alström’s Warbler Phylloscopus soror, so we have revised this option to include that species as well.

Our New Zealand team has reviewed the taxonomy of the introduced and established redpolls in New Zealand. Although there may be some hybridization in their past, New Zealand editors now consider the population to pertain to Lesser Redpoll Acanthis cabaret and does not consider Common Redpoll Acanthis flammea to occur in New Zealand (and nearby areas). We have updated the records accordingly in eBird.

When we added two new slashes last year we reversed the scientific names for each of them, so that Grasshopper/Baird’s Sparrow carried the scientific names for Grasshopper/Henslow’s, and vice versa. Ooops! If you have reported any of these, please make sure that you did so based on the English name–if you used the scientific name, your records may have ended up in the wrong option. The names are now corrected.


When subspecies move around between species, this can have effects like splits or lumps. Thus, for a certain population within a species, the movement of the subspecies from one to another has important data quality implications and can significantly change the range of both species.

Subspecies approximans is the common vireo on Providencia Island in the Caribbean (off the coast of Nicaragua, but governed by Colombia). Some authorities (e.g., IOC) treat is as a species in its own right (Providencia Vireo Vireo approximans), but when it is not recognized as a species it is usually considered a subspecies of Mangrove Vireo Vireo pallens. Our treatment, however, deferred to the AOS-NACC, which treated it as a subspecies of Thick-billed Vireo Vireo crassirostris, until a review of other taxonomies and vocal differences (the voice sounds much more like Mangrove Vireo than thick-billed) revealed it is better treated as a subspecies of Mangrove Vireo. We retain it as a distinctive subspecies group, though the names have changed as the parent species has changed.

Newly recognized subspecies manengubae is added to Evergreen-forest Warbler Bradypterus lopezi with range “Mt. Manenguba (southwestern Cameroon).” This subspecies had been considered a junior synonym of Bangwa Warbler Bradypterus bangwaensis, but Bangwa Warbler and manengubae are sympatric on Mt. Manenguba, however, and so we in recognizing manengubae as a valid taxon. All this is complicated and tricky, but it does result in a minor change to our understanding of the range for both species.

Subspecies canturians, previously included in Japanese Bush Warbler Horornis diphone, instead belongs with Manchurian Bush Warbler, which then must change from Horornis borealis to Horornis canturians. The range of subspecies canturians is “breeds eastern China (Gansu and Sichuan east to Anhui and Zhejiang); winters to southern China, Taiwan, northeastern India (Assam), northwestern Thailand, Indochina, and the northern Philippines.”

Subspecies clarki belongs with Burmese Yuhina Yuhina humilis, not with Whiskered Yuhina Yuhina flavicollis. Its range is “Mountains of e Myanmar (S Shan State and Karenni State)” so this adjustment makes a minor change to the range of both species.

Subspecies aenigmaticus, with range “SW Colombia (Nariño)”, indeed is enigmatic. Originally described as a subspecies of Thrush-like Wren Campylorhynchus turdinus, it now is considered to represent hybrids between White-headed Wren and Band-backed Wren Campylorhynchus zonatus. This results in a minor change in the range of White-headed Wren and necessitates the addition of the hybrid, which we did not previously have in our taxonomy.

  • White-headed Wren Campylorhynchus albobrunneus [map] [species page] [my records]
    • White-headed x Band-backed Wren Campylorhynchus albobrunneus x zonatus [map]

Subspecies rubronigra with range “N India (Haryana to n Bihar) and lowlands of Nepal” is moved from Tricolored Munia Lonchura malacca to Chestnut Munia Lonchura atricapilla, which means that the native range of Tricolored Munia is restricted to the southern half of India and Sri Lanka, although it has also been introduced widely including in northern India.

Two subspecies, saphiroi and goodsoni, that we have treated within Buffy Pipit Anthus vaalensis are transferred to Plain-backed Pipit Anthus leucophrys. The new names and ranges are Anthus leucophrys saphiroi from “SE Ethiopia and nw Somalia” and Anthus leucophrys goodsoni with range “C and sw Kenya to extreme n Tanzania”.


Revisions to eBird subspecies groups, and occasionally other taxa (like spuhs or slashes), can happen in our taxonomic update as well. This effectively changes the definition for these taxa and also changes how you should use them in reporting. To review your records of any of the subspecies groups below, simply open your Life List on eBird and use a browser search to search for the species name in question. Click the species to open all reports for that species; your subspecies reports will appear in this list and you can review those for accuracy. Selected revisions are listed below; for a complete listing of these changes see the Clements updates.

Subspecies aphanes, which we have considered to be a junior synonym of Vaux’s Swift (Ashy-tailed) Chaetura vauxi andrei since Clements Checklist 6.4 (2009), is reinstated; genetic evidence shows that andrei and aphanes are separate taxa. We recognize aphanes as a new monotypic group, Vaux’s Swift (aphanes) Chaetura vauxi aphanes, with range “northern Venezuela (coastal ranges, from Lara and Yaracuy east to Sucre and Monagas)”.

Collared Inca Coeligena torquata: Collared Inca (Green) Coeligena torquata conradii and Collared Inca (Vilcabamba) Coeligena torquata eisenmanni are split out from Collared Inca (Collared) Coeligena torquata [torquata Group]. We retain Collared Inca (Gould’s) Coeligena torquata inca/omissa as the fourth identifiable subspecies group.

Amazilia Hummingbird Amazilia amazilia: Amazilia Hummingbird (Loja) Amazilia amazilia alticola is no longer recognized as a group and is “lumped” with Amazilia Hummingbird (Amazilia) Amazilia amazilia [amazilia Group]. At the same time, we recognize two new groups; thew White-throated group includes subspecies dumerilii, azuay, alticola, and leucophoea. Here are the groups we have now:

  • Amazilia Hummingbird (White-throated) Amazilia amazilia [dumerilii Group]
  • Amazilia Hummingbird (Green-throated) Amazilia amazilia amazilia
  • Amazilia Hummingbird (Blue-throated) Amazilia amazilia caeruleigularis

Crested Serpent-Eagle (Andaman) Spilornis cheela: We add new subspecies group Crested Serpent-Eagle (Andaman) Spilornis cheela davisoni which is split out from Crested Serpent-Eagle (Crested) Spilornis cheela [cheela Group].

Roadside Hawk (Southern) Rupornis magnirostris: We erred last year by including subspecies occiduus, with range “W Amazonian Brazil, e Peru and n Bolivia” in the polytypic group Roadside Hawk (Southern) Rupornis magnirostris [pucherani Group] and this year add it to Roadside Hawk (Northern) Rupornis magnirostris [magnirostris Group]; this significantly extends the range of the Northern group and restricts the range of the Southern group.

Collared Trogon Trogon collaris: See “Lumps and Unrecognized species” for these revisions.

Orange-breasted Fig-Parrot (Creamy-breasted) Cyclopsitta gulielmitertii amabilis/ramuensis is split from Orange-breasted Fig-Parrot (Black-fronted) Cyclopsitta gulielmitertii nigrifrons N New Guinea. Both occur in New Guinea, with Creamy-breasted in the Northeast and Black-fronted in the North.

Maroon-tailed Parakeet (Huila) Pyrrhura melanura chapmani of the Subtropical e slope of Central Andes of s Colombia is split from Maroon-tailed Parakeet (Maroon-tailed) Pyrrhura melanura [melanura Group] which extends from s Colombia to e Ecuador, n Peru, s Venezuela and nw Brazil

Subspecies scapularis removed from the polytypic group Rufous-winged Antwren (Northern) Herpsilochmus rufimarginatus [scapularis Group] and now is transferred to the group Rufous-winged Antwren (Southern). Below are the ranges with subspecies:

  • Rufous-winged Antwren (Northern) Herpsilochmus rufimarginatus frater/exiguus
    • Herpsilochmus rufimarginatus exiguus
      • Pacific slope of e Panama (e Darién)
    • Herpsilochmus rufimarginatus frater
      • base of Andes from Colombia south to northern Bolivia, east to southwestern Amazonian Brazil (Rondônia and northern Mato Grosso); Venezuela; southern Guyana, central Suriname, and northern Brazil (northern Roraima);northeastern Brazil (southern Pará and western Maranhão, also Paraíba south to Alagoas
  • Rufous-winged Antwren (Southern) Herpsilochmus rufimarginatus rufimarginatus/scapularis
    • Herpsilochmus rufimarginatus scapularis
      • northeastern Brazil (Bahia to Espírito Santo and Minas Gerais)
    • Herpsilochmus rufimarginatus rufimarginatus
      • SE Brazil (Rio de Janeiro) to e Paraguay and ne Argentina

Creamy-breasted Canastero (Huancavelica) Asthenes dorbignyi huancavelicae from Huancavelica in the arid Andes of sw Peru is split out from Creamy-breasted Canastero (Pale-tailed) Asthenes dorbignyi usheri from the arid Andes of s-c Peru in Ancash to Apurímac.

Green-backed Becard (Green-cheeked) Pachyramphus viridis griseigularis from SE Venezuela (e Bolívar) and lower Amazonian Brazil and Green-backed Becard (Green-backed) Pachyramphus viridis viridis E Bolivia to n Argentina, e Uruguay, Paraguay and e Brazil are split; they were formerly considered part of the same group, but each is distinctive.

Bran-colored Flycatcher (Mouse-gray) Myiophobus fasciatus crypterythrus from the Pacific slope of South America (Colombia south to northern Peru) is split from the widespread Central and South American group Bran-colored Flycatcher (Bran-colored) Myiophobus fasciatus [fasciatus Group], which occurs east of the Andes in the countries where both forms occur (s. Colombia, Ecuador, Peru).

Rufous-naped Ground-Tyrant (Chestnut-naped) Muscisaxicola rufivertex occipitalis from the Andes of Peru and n Bolivia (La Paz and Cochabamba) is split from Rufous-naped Ground-Tyrant (Rufous-naped) Muscisaxicola rufivertex rufivertex, which occurs from Andes of s Chile and s Argentina; winters north to Antofagasta.

Subspecies goodsoni, with range S New Guinea (Merauke District), is removed from the polytypic group Little Shrikethrush (Arafura) Colluricincla megarhyncha [megarhyncha Group], and is placed in the polytypic group Little Shrikethrush (Rufous) Colluricincla megarhyncha [rufogaster Group]. See Clements Checklist for full details.

A new subspecies Dicrurus adsimilis jubaensis from Ethiopia, Eritrea, and Somalia is added to the Fork-tailed Drongo (adsimilis Group) Dicrurus adsimilis [adsimilis Group].

Eurasian Skylark (Asian) Alauda arvensis [pekinensis Group] and Eurasian Skylark (Far Eastern) Alauda arvensis japonica/intermedia are divided into two groups (formerly Eurasian Skylark (Asian) Alauda arvensis [japonicus Group]). Differences in display, flight call, and song suggest there could be species-level differences here and we recommend supporting any records with audio recordings or detailed notes.

Rock-loving Cisticola (Huambo) Cisticola aberrans bailunduensis of central Angola is split from the Rock-loving Cisticola (Rock-loving) Cisticola aberrans [emini Group] of which occurs from Guinea to Sierra Leone, Mali and s Ghana south and east to ne Democratic Republic of the Congo, s South Sudan, and n Tanzania

Two additional groups are split from Zitting Cisticola (Zitting) Cisticola juncidis [juncidis Group]:

  • Zitting Cisticola (tinnabulans Group) Cisticola juncidis [tinnabulans Group]
      • S China to Indochina, Hainan, Taiwan and Philippines, Indonesian islands, New Guinea and Australia
  • Zitting Cisticola (Eastern) Cisticola juncidis brunniceps
      • Japan (Honshu to Ryukyu, Izu and Cheju-Do is.) to n Philippines

In earlier treatments, we erroneously placed subspecies stuarti with Northern Rough-winged Swallow (Northern) Stelgidopteryx serripennis [serripennis Group] but correctly place it with the distinctive Northern Rough-winged Swallow (Ridgway’s) Stelgidopteryx serripennis ridgwayi/stuarti now.

Shelley’s Greenbul Arizelocichla masukuensis: See “Splits” above for the changes in this species and Eastern Mountain Greenbul.

Eastern Mountain Greenbul Arizelocichla nigriceps: See “Splits” above for the changes in this species and Shelley’s Greenbul.

Subspecies remotus is removed from the polytypic group Ashy Bulbul (Ashy) Hemixos flavala [flavala Group] and now is recognized as a new monotypic group, Ashy Bulbul (Brown-backed) Hemixos flavala remotus, occurring in an area of endemism in S Vietnam (Bolavens and Langbian plateaux)

Abyssinian White-eye (Socotra) Zosterops abyssinicus socotranus, which occurs on Socotra and also n Somalia, is split from Abyssinian White-eye (Abyssinian) Zosterops abyssinicus [abyssinicus Group].

Our Capuchin Babbler (Capuchin) Turdoides atripennis atripennis/rubiginosus group is split into Capuchin Babbler (Gray-hooded) Turdoides atripennis atripennis of the Gambia to Ivory Coast and Capuchin Babbler (Black-crowned) Turdoides atripennis rubiginosus which occurs from Ivory Coast to s Nigeria.

Meves’s Starling (Cunene) Lamprotornis mevesii violacior from N Namibia and sw Angola is split from Meves’s Starling (Meves’s) Lamprotornis mevesii mevesii, which occurs in Angola and n Namibia to Botswana, s Malawi and ne S Africa

Subspecies rudolfi, which we previously included as Moorland Chat (Rudolf’s) Pinarochroa sordida rudolfi with range “N Kenya (Mt. Elgon moorlands) and adjacent e Uganda”, is considered to be a junior synonym of ernesti and is deleted. This population thus becomes part of our Moorland Chat (Mt. Kenya) Pinarochroa sordida ernesti subspecies group with the revised range “highlands of extreme eastern Uganda and of western and central Kenya”.

Red-headed Fody (Grand Comoro) Foudia eminentissima consobrina of Grand Comoro I. (Comoro Islands) is split from
Red-headed Fody (Southern Comoros) Foudia eminentissima [eminentissima Group] of Anjouan, Mohéli, Mayotte

We recognize a new “Caribbean” group in Grayish Saltator and revise the subspecies involved with all three groups. The Middle American group is restricted to Mexico and Central America, the Caribbean group occurs in Caribbean lowlands of Colombia (a few recent records from eastern Panama), Venezuela, Trinidad, the Guianas, and Brazil, and the Amazonian group occurs in…Amazonia. The Clements Checklist v2019 will give more details on the subspecies and ranges involved.

  • Grayish Saltator (Middle American) Saltator coerulescens [grandis Group] [map]
  • Grayish Saltator (Caribbean) Saltator coerulescens [olivascens Group] [map]
  • Grayish Saltator (Amazonian) Saltator coerulescens [coerulescens Group] [map]


The following new subspecies groups are now available for data entry. When you are certain you have seen representatives of these groups, and ideally have identified them critically based on their field marks, please report them to eBird. Please do not guess based on the name, such as “Northern” and “Southern” or “African” and “Asian”; make sure you understand the differences being represented before reporting at so specific a level. Many new subspecies groups were added this year, largely because of additional review of the work by Nigel Collar and the Birdlife International team, who have assessed a large number of avian taxa based on morphological and acoustic information and scored their relative distinctiveness (also known as the Tobias criteria). While we don’t necessarily follow the species-level splits from Handbook of the Birds of the World, these were useful for helping identify additional distinctive subspecies groups, resulting in a good number of additions this year.

eBird has a long list of field identifiable hybrids. These are always listed in taxonomic order (the species that comes first sequentially is listed first) and are always followed by “hybrid”. If you identified a hybrid, especially any of the below, please do report it to eBird (hopefully with photos)! eBird also maintains a much shorter lists of intergrades (hybrids between subspecies groups); these always list the species name followed by a parenthetical notation that shows what two subspecies groups have hybridized (e.g., Northern Flicker (Yellow-shafted x Red-shafted) and also can be identified from the scientific name by the structure of the names which indicates that it is a subspecies. Hybrids and intergrades are unique to the eBird taxonomy; they are not found in the Clements Checklist.

With Change Species, eBirders can quickly update their lists if you already have an entry of any of these (e.g., under duck sp. or hummingbird sp.).

The eBird/Clements taxonomy did not previously have a formal policy regarding extinct species, but this year we adopt the same standard that is used by other global bird lists, namely the Birdlife International/Handbook of the Birds of the World (HBW) taxonomy and the International Ornithological Committee (IOC). Our taxonomy is now expanded to include all species that were known to persist beyond the year 1500, which results in the following additions to our taxonomy. We don’t expect many eBird reports of these species, sadly, but we do plan to have new species accounts available for them soon to help understand the avian biodiversity that has already been lost. Most of these were island endemics that disappeared as Europeans first arrived on remote islands.

Within eBird, we also have forms for taxa that are field identifiable (or likely potential species) and worth tracking, but are not formally described. These include undescribed species and undescribed subspecies groups (both noted with “undescribed form”), slashes at a level between subspecies group and species (e.g., “Whimbrel (White-rumped)” below) and miscellaneous other options. This year’s update includes an enigmatic steamer-duck from Chiloe Island, tentatively placed within the Flightless Steamer-Duck Tachyeres pteneres, two poorly known taxa represented by just one or two specimens, and a new reporting option for Lesser Black-backed Gull for birds that can be narrowed to one of two very similar subspecies. Forms are unique to the eBird taxonomy; they are not found in the Clements Checklist.

  • Flightless Steamer-Duck (Chiloe form) Tachyeres pteneres [undescribed form]
  • Guanacaste Hummingbird (unrecognized species) Amazilia alfaroana [unrecognized species]
  • Lesser Black-backed Gull (intermedius/graellsii) Larus fuscus intermedius/graellsii
  • White-tailed Tityra (unrecognized species) Tityra leucura [unrecognized species]


eBird has certain domesticated species that are regularly seen in a feral or wild state. The distinction between a “Domestic” and a wild type bird of the same species is in its appearance, and domestics are always identifiable as having domestic ancestry, often in their white, yellow, or otherwise abnormal plumage, or less often, in their size or shape (e.g., Graylag Goose (Domestic type) is larger and more pot-bellied than wild Graylag Geese). Domestics are unique to the eBird taxonomy; they are not found in the Clements Checklist. We have not added any domestics for 2019.

  • No additions for 2019


As with hybrids, eBird has a long list of “slashes” and “spuhs”. These are useful in the field if you get a good enough look at a bird to know it, for example, a scoter, but not to tell if it was a Common Scoter, Black Scoter, Surf Scoter, Velvet Scoter, White-winged Scoter, or Stejneger’s Scoter. You can use “scoter sp.”, in such instances. If you are able to narrow it down to two (or in rare cases, three or four) species options, we have “slashes”, which mention the full common name (and scientific name) for the species that are potential species for your observation (e.g., Surf/Black Scoter). This list is being regularly updated as observers let us know what field identification problems they encounter. Slashes and spuhs are unique to the eBird taxonomy; they are not found in the Clements Checklist.

See the Clements Checklist updates (here) for the reasoning behind these name changes. Note that some relate directly to splits discussed above, since some of the taxa that were formerly species may appear here. For example, if a widespread bird that occurs in North America and Eurasia is split into unique species on each continent, the population occurring on both continents might be retained here as a “slash” and appear as a name change (also a downgrade from species to slash). Other name changes may be driven by changes in taxonomic sequence (as with hybrids and slashes, where the first-listed species always comes first), an attempt to follow an emerging consensus in local usage, or a taxonomic revision that affects hyphenation rules. Other general changes, including corrections and decisions to use an alternate common name, have been made here.

See the Clements Checklist updates (to be posted soon here) for full discussion of the reasoning behind these name changes. Note that some relate directly to splits discussed above, since some of the taxa that were formerly species may appear here. For example, if a widespread bird that occurs in North America and Eurasia that is split into unique species on each continent, the population occurring on both continents might be retained here as a “slash” and appear as a name change (also a downgrade from species to slash). We display the primary English name as well, using the 2019 name (thus, the English name would match the revised Scientific Name in instances of a split).

This year there continue to be some significant changes to the taxonomic sequence. As always quick entry codes and Smart Sort for data entry on the web and via eBird Mobile is very easy and makes it less necessary to try to memorize the sequence. Please see this article to understand how to use easy to learn four-letter codes to enter data quickly (did you know that typing “37 hosp” in eBird mobile will quickly add 37 House Sparrows to whatever total you have already entered? Learn how!).

The main changes to families this year involve two mergers and one family expansion:

  • Sylviidae (Sylviid Warblers) and Paradoxornithidae (Parrotbills, Wrentit, and Allies) are merged into an expanded Sylviidae (Sylviid Warblers, Parrotbills, and Allies)
  • Artamidae (Woodswallows) and Cracticidae (Bellmagpies and Allies) are merged into an expanded Artamidae (Woodswallows, Bellmagpies, and Allies)
  • In addition, three genera previously included (with much uncertainty) in Tyrannidae–Royal Flycatcher Onychorhynchus coronatus, Ruddy-tailed Flycatcher Terenotriccus erythrurus, and members of the genus Myiobius are merged into Oxyruncidae, which used to be Oxyruncidae (Sharpbill) and is now expanded to be Oxyruncidae (Sharpbill, Royal Flycatcher, and Allies)

The sequence of many families is revised again as we finally align towards a more stable family-level sequence supported by the best and most current genetic information. Please see the Clements update for more information on this.
