First Wisconsin Breeding Bird Atlas Data Uploaded!


In preparation for Wisconsin Breeding Bird Atlas II, beginning soon, we have just loaded about 166,000 records from the first Wisconsin Breeding Bird Atlas into eBird. And, if you participated in the first atlas, we were able to load these records directly into your eBird account. Read on to find out more.

December Hotspot of the Month–Bakken’s Pond


For December 2014’s Wisconsin Hotspot of the Month, we visit Sauk County with Aaron Holschbach as our tour guide. Located in the far southwestern corner of Sauk County, between the villages of Spring Green and Lone Rock, is the Bakken’s Pond Unit of the Lower Wisconsin State Riverway. Along the north shore of the Wisconsin River, this area hosts large numbers and varieties of bird species (especially during spring migration).

Wisconsin Breeding Bird Atlas II – Kickoff Meeting


In 1995, the first Atlas was started. This project involved over 1,600 observers, who amassed more than 170,000 observations of 237 species. Twenty years later, it’s time to do it again in order to ensure we have the information necessary to conserve our breeding birds, an integral part of Wisconsin.

The atlas will also be the first bird atlas to be fully integrated with eBird! Read on to find out about the kickoff meeting, where you can meet and bird with eBird Project Leader Chris Wood!

November Hotspot of Month–Cruson Slough

Cruson Slough by Barb Duerksen

November’s Hotspot of the Month takes us to Cruson Slough in Richland County. Veteran birder and resident of Richland County, Barb Duerksen, is our “tour guide” for this month. The slough is an old oxbow of the Wisconsin River located immediately west of Smith Slough and Sand Prairie State Natural Area. It has a dike on the west end, with the overflow running west to the Wisconsin River. Cruson Slough is part of the Lone Rock Unit of the Lower Wisconsin State Riverway. The eBird hotspot encompasses both the sloughs and surrounding areas. Habitat includes open water in the sloughs, wetlands, sedge meadow, sand prairie, barrens, river bottom forest, and the river along the southern edge.

September Hotspot of the Month-Muskeg Creek Bog

For September’s Wisconsin eBird Hotspot of the Month, local eBirder, Tim Oksiuta, takes us on a tour of Muskeg Creek Bog in Bayfield County. Muskeg Creek Bog (referred to as the Muskeg Creek Area in eBird) is an approximately 80 acre bog with a diverse variety of habitat. The Muskeg Creek Area lies approximately 5 miles west of Iron River, WI or 5 miles east of Brule, WI on the north side of Highway 2. Access can be gained from Hollander Road on the west side or Stephan’s Road on the east side. The bog is easily traversed for approximately 1 mile by the Tri-County Corridor which is a an abandoned railroad grade, now used as a snowmobile/4-wheeler trail. Muskeg Creek flows through the bog.

August Hotspot of the Month–1000 Islands Environmental Center

Our randomly selected county for August’s Wisconsin eBird Hotspot of the Month is Outagamie. Tony Nowak, Kaukauna resident, local birder and eBird contributor, chose to profile 1000 Islands Environmental Center and some nearby spots that are also worth birding. 1000 Islands Environmental Center is a 350 acre conservancy zone located along the Fox River in the City of Kaukauna. The property contains 7.2 miles of trails and a nature center that offers educational displays, live animal exhibits and year round programming. With its proximity to the Fox River, a variety of habitat and easy access,1000 Islands is an excellent birding destination.

Taxonomy update for 2014

For American birders, large rail splits are most likely to give Life Lists a boost in this revision. Be careful reporting Clapper Rail: it should only be used for East Coast and Gulf Coast birds now! Photo of Clapper Rail in Massachusetts by Ryan Schain.

The taxonomic update for 2014 is now complete in eBird. The names and sequence have been changed and eBird records have been updated in cases of splits and lumps. This update includes taxonomic revisions introduced (or accepted) since August 2013 by the two committees of the American Ornithologists’ Union, the North American Classification Committee (NACC) and the South American Classification Committee (SACC), including several splits detailed below. In North America the most significant change was the split of Clapper Rail into Clapper, Ridgway’s, and Mangrove Rails and the split of King Rail into King and Aztec Rails. In the tropical Americas, Sirystes was split into four species, Bicolored Antbird was split into two, and Knipolegus black-tyrants were revised, among others. In Eurasia, Mourning Wheatear was split into three species, Arctic Warbler was split into three species (two occur in North America, one as a breeder and one as a vagrant or rare migrant) and Two-barred Warbler was split from Greenish Warbler.

July Hotspot of Month–6th Avenue Marsh

6th Avenue Marsh by Mike Reese

With July being the month when shorebirds commence their southerly migration through Wisconsin, it seems fitting that one of Adams County’s top shorebirding hotspots is chosen as the Hotspot of the Month. Rob Pendergast, leading eBirder for Adams County, takes on a tour of 6th Avenue Marsh. Located in the northwestern portion of Adams County, 6th Avenue Marsh is a premier location for avian life. This man-made marsh was created for irrigating cranberry crops during the summer months. The water is increasingly drawn down as summer progresses to fall which has the benefit of attracting an impressive diversity of shorebirds. The best vantage point is along 6th Avenue, ¼ mile south of County Highway D. Viewing the marsh is limited to the roadside as this area is privately owned.

Got shorebirds? Your guide to finding them in fall 2014

Semipalmated Sandpiper by David Franzen

Shorebirds are on the move again, stopping over at suitable habitats here in Wisconsin en route from Canadian breeding areas to wintering areas well to our south. As in previous years, Wisconsin DNR staff have highlighted this fascinating group of early migrants with a featured news story outlining the management of shorebird habitat, how birders […]

June Hotspot of the Month–Tiffany Wildlife Area

Tiffany Railway at Tiffany State Wildlife Area

June’s Wisconsin eBird Hotspot of the Month takes us to Buffalo County. Anne Geraghty, a high school biology teacher from nearby Eau Claire, leads us on an exciting tour of the Tiffany Wildlife Area (WA). Buffalo County is a great place for birds and birders. Its southwestern border is the Mississippi River, which twice a year offers up the spectacle of tundra swans and other waterfowl in migration. The blufflands, which comprise the majority of the county, are perhaps the best area in the state to find overwintering golden eagles. At its southern tip, Buffalo County contains part of the Trempealeau National Wildlife Refuge (NWR), and on its western border, it shares the Tiffany Wildlife Area (WA) with adjacent Pepin County. While the Trempealeau NWR gets its fair share of birding attention, the Tiffany WA does not – and it probably deserves better!
