Great Backyard Bird Count results

Between Feb. 15 and 18, birders submitted more than 85,700 checklists, identified 635 species and provided thousands of bird photos. The citizen scientists contributed to a database that ornithologists and other researchers can use to study species populations and distribution.

For instance, counters' checklists indicate that
* northern finches, such as Pine Grosbeak (above), came south from northern Canada to find food
* Yellow-billed Magpie populations are decreasing
* Eurasian Collard-Doves continue to adapt and spread, now reaching Oregon and the Canadian provinces of British Columbia and Manitoba

The top 10 most reported species:
1. Northern Cardinal
2. Mourning Dove
3. Dark-eyed Junco
4. Downy Woodpecker
5. American Goldfinch
6. Blue Jay
7. House Finch
8. Tufted Titmouse
9. Black-capped Chickadee
10. American Crow
