Great Backyard Bird Count produced a “gold mine” of information
When tens of thousands of people watch birds and report what they see online, they create a snapshot showing the whereabouts of many hundreds of bird species across the United States and Canada. This annual gold mine of information about birds comes from participants in the Great Backyard Bird Count (GBBC), a joint project of the National Audubon Society with Canadian partner Bird Studies Canada.
This year, an estimated 60,000 bird watchers of all ages took part in the free, four–day event held February 18– 21. Participants identified 596 species and filed 11.4 million individual bird observations. Their reports provide useful information to scientists tracking changes in the numbers and movements of birds from year to year, just as winter is about to melt into spring.

Top 10 birds reported on the most checklists in the 2011 GBBC were Northern Cardinal, Mourning Dove, Dark– eyed Junco, Downy Woodpecker, American Goldfinch, Blue Jay, American Crow, Black– capped Chickadee, House Finch, and Tufted Titmouse.
