Join the tens of thousands of people who keep tabs on the birds that come to their feeders from November through April. Participants submit their observations to the Cornell Lab of Ornithology.

Observations help reveal important patterns in bird distribution and numbers that may be changing over time on a continental scale or in a participant’s own backyard.

To sign up, visit www.FeederWatch.org or call the Cornell Lab toll-free at 866-989-2473. In return for the $15 fee ($12 for Cornell Lab members), participants receive the FeederWatcher Handbook and Instructions with tips on how to successfully attract birds to feeders, an identification poster of the most common feeder birds, and a calendar. Participants also receive “Winter Bird Highlights,” an annual summary of FeederWatch findings, as well as the Cornell Lab’s quarterly newsletter, “Living Bird News.”

Project FeederWatch is a joint research and education project of the Cornell Lab of Ornithology and Bird Studies Canada. Observations from a record number of participants last season helped scientists follow the changes in woodpecker and nuthatch populations in the Midwest where trees were infested with invasive emerald ash borer beetles.
