Red-winged Blackbird (Red-winged)

This is another of the "core" subspecies that I think are important/helpful to include. (Red-winged) ssp group birds are not only the only form in CT year round, but are easily field identifiable as well. Identification of males is very straightforward because "Bicolored" types lack the yellow on the wing patch of (Red-winged) types. The two other "Bicolored" subspecies have only red on the wing patch. Female (Red-winged) are identified by their lighter brown color compared to "Bicolored" birds which are significantly darker. Nominate ssp group females/young males also have a streaked appearance on the breast, where Bicolored ssp birds are more uniform dark brown.

There is little to no risk of overassumption of the subspecies of these birds in CT because they are the only likely form by range, and are easily field identifiable. I think that it would be helpful to allow birders to submit RWBLs as (Red-winged) if they wish because of these reasons. I request that this subspecies could be considered to be added to the filters.

Yellow Warbler (Northern)

-Subspecies groups within Yellow Warbler are distinctive in both plumage and voice, and are very likely separate species. Songs differ significantly between groups, and birds are certainly field identifiable based on plumage details as well. All birds in CT are Northern/American Yellow Warbler- and I think it would be helpful for birders to be able to include that on checklists if they wish. There is no risk of overassumption as this is the only expected form, and in addition, birds in CT are identifiable to this type by plumage and/or voice in essentially 100% of scenarios. I would request that this is considered for addition to the filters, as recommended by eBird central documents and filter recommendation Excel spreadsheets, along with other field identifiable subspecies.

https://www.allaboutbirds.org/guide/Yellow_Warbler/id

-Quote from David Sibley's blog post on field identifiable subspecies in North America:
"Three major groups are distinctive. Within the Northern group it is often possible to identify migrants as belonging to, for example, a northern population based on drab color and/or timing of migration, but this is not enough to allow a subspecies label. Golden and Mangrove populations are both distinctive and identifiable".
