2017 Christmas Bird Count Sets New Record in Brodhead Area

On a chilly mid-December day, Quentin Yoerger and nine other volunteers, including Aaron Haycraft, Andy Paulios, David Huset, Fred Dike, Marty Evanson, Mike Ramsden, Rebecca Gilman, Tom Klubertanz, and Susan Lehnhardt systematically surveyed a circular plot with a 15-mile radius centered over Brodhead, recording each bird species observed and counting their numbers.  Their windshield and on-the-ground searches focused on the wide-ranging natural and cultural habitats that occupy this part of the Lower Sugar River Watershed, including backyard feeders.  

By the end of the day, they had set a new record for the number of species found on the Brodhead count—56 species on the day of the count (December 14), plus an additional three “count week” species.  In addition, they tallied 7,043 individual birds, which is above the 13 year average of 6,328 in the Brodhead area.  More on the 2017 results below.  In the meantime…

What is the Christmas Bird Count?

The National Audubon Society has been sponsoring Christmas Bird Counts across North America for more than 100 years.  It is the longest running Citizen Science survey in the world, with tens of thousands of professional and amateur bird watchers participating every year. The post-migration, early winter data is an important contribution to understanding resident and migratory bird population trends.  To learn more about the CBC and how to get involved, go to the Wisconsin Society for Ornithology website  or contact your local bird organization Green Rock Audubon Society and the Ned Hollister Bird Club.

The complete history of the count beginning in 2005 can be found in a spreadsheet here

This year, three new species included a Northern Saw-whet Owl, Yellow-rumped Warbler, and two Harris's Sparrows (see photo of sparrow here).  Seven species of sparrow are a new high, but, as Quentin noted, they missed out on Song Sparrow for the first time ever!  

Several species were found in 2017 for only the second time ever.  (Note:  “cw” means “count week”, additional birds observed during the week of the CBC.)
