Thousands of FeederWatchers in communities across North America count birds and send their tallies to the FeederWatch database, creating a treasure trove of statistics that FeederWatch scientists analyze to draw a picture of winter bird abundance and distribution. FeederWatch data show which bird species visit feeders at thousands of locations across the continent every winter. The data also indicate how many individuals of each species are seen. This information can be used to measure changes in the winter ranges and abundances of bird species over time.
FeederWatch data provide a picture of weekly changes in bird distribution and abundance across the United States and Canada. Importantly, FeederWatch data tell us where birds are as well as where they are not. This crucial information enables scientists to piece together the most accurate population maps.
FeederWatch is a joint research and education project of The Cornell Lab of Ornithology and Bird Studies Canada. They have provided an instructional video on the FeederWatchers Web site.
