Citizen-science participants found 619 species of
birds and broke two major records during the
2009 Great Backyard Bird Count (GBBC). They submitted
93,629 checklists and tallied 11,550,200 birds
during February 13–16. This represents a 9 percent increase
in checklist submissions over the last record,
and a new high for numbers of birds counted.
Participants documented a massive influx of Pine
Siskins. They counted 279,469 Pine Siskins on 18,528
checklists, up from a previous high of 38,977 birds on
4,069 checklists in 2005.

Led by the Cornell Lab of Ornithology and the National
Audubon Society, the GBBC has provided a detailed
real-time snapshot of bird distribution across the
continent for 12 years. Although in-depth studies are
necessary to confirm trends in bird distribution found
during the GBBC, and to document their causes, these
preliminary results are often clear indicators of how
birds are responding to changes in our environment.
