Sign up at FeederWatch.org to support the scientific study and conservation of birds with your observations.
"Currently, we are tracking several range expansions in both the western and eastern part of the continent," says project leader Emma Greig. "We are seeing that Lesser Goldfinches, Anna’s Hummingbirds, and Bushtits are on the rise in the West, and we are still investigating the causes. Northern Cardinals, Red-bellied Woodpeckers, and Carolina Wrens are expanding their ranges in the East, and scientists think it may be due to climate change. We need everyone's observations to detect these kinds of large-scale trends in bird populations."
More than 20,000 FeederWatchers contribute their data by reporting the highest number of each species they see at their feeders during periodic two-day counts through early April.
For a $18 fee ($15 for Cornell Lab members), U.S. participants receive the FeederWatch 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 printed newsletter, All About Birds News. The fee is $35 in Canada.
Happy Birding!
