Volunteer: Cornell Orinthology Lab Bird Feeder Watch

­The 2008-09 season of the Cornell Lab of Ornithology’s Project FeederWatch gets underway November 8 and runs through April 3. For more then 20 years participants have been counting the numbers and kinds of birds at their feeders each week and sending the information to the Ornithology Lab. Participants submitted more than 115,000 checklists during the 2007-08 FeederWatch season, documenting unusual bird sightings, winter movements, and shifting ranges-­a treasure-trove of information that scientists use to monitor the health of the birds and of the environment.

“Being a FeederWatcher is easy and fun, and at the same time helps generate the world’s largest database on feeder-bird populations,” says project leader David Bonter. “We are grateful for the contributions our participants have made for the birds and are proud of the joy they say it brings to their busy lives. Since we started in 1987, more than 40,000 people have submitted observations, engaging with the wildlife beyond their windows.”

Scientists learn something new from the data each year, too, whether it’s about the movements of common backyard birds or unusual sightings of rarely-seen species. Highlights of the most recent season include the largest southward movement of Red-breasted Nuthatches in the history of the project­-part of an expected influx of northern birds that fly farther south when their food supplies run short.

Other northern species showing up in record numbers included Common Repolls and Pine Siskins. Among the rare birds reported was a Streak-backed Oriole in Loveland, Colorado-­the state’s first report of this bird, native to Mexico. A December nor’easter deposited a Dovekie in Newton, Massachusetts, the first time this North Atlantic seabird has ever been reported to Project FeederWatch.

Long-term data show some species increasing in number, such as the Lesser Goldfinch in the Southwest. Other populations continue a downward trend, such as the Evening Grosbeak throughout their range. Once one of the most common species seen at feeders in the northern half of the continent, the grosbeaks are declining for unknown reasons.

Beyond the benefits to birds and science, however, is the benefit to participants. “Nature is not merely an amenity; it is critical to healthy human development and functioning,” says Nancy Wells, Cornell University assistant professor of design and environmental analysis. Her studies find that a view of nature through the window or access to the environment in any way improves a child’s cognitive functioning and reduces the negative effects of stress on the child’s psychological well-being. Wells also notes that when children spent time with nature early in life it carries over to their adult attitudes and behavior toward the environment.

Project FeederWatch welcomes participants of all ages and skill levels, from scout troops and retirees to classrooms and nature center visitors. To learn more and to sign up, visit www.feederwatch.org or call the Lab toll-free at (800) 843-2473. In return for the $15 fee ($12 for Lab members) participants receive the FeederWatcher’s Handbook, an identification poster of the most common feeder birds in their area, a calendar, complete instructions, and the FeederWatch annual report, Winter Bird Highlights.
