Become a Citizen Scientist As You Feed the Birds

It's that time of year again — the weather's getting colder, and it's time to start preparing for the winter. As our gardens begin to go dormant, we can think ahead to the joy that bird feeding will bring. Fall is a good time to wash the feeders and to stock up on seed.

A few common questions and myths persist about bird feeding. First, the birds will not become dependent on your feeder as a source of food. While they may eat at the feeder on a daily basis, birds consume many other sources of natural food each day. However, feeders do help some birds find a reliable source of food during heavy snow or ice storms, so you may want to have someone keep it full when you're not available.

Uncooked rice doesn't expand in birds' stomachs and kill them. Many species of birds eat rice and other grains in the fields where they grow and are not harmed. Also, peanut butter doesn't stick in birds' throats and choke them. You can mix cornmeal, oatmeal, grit or birdseed with the peanut butter to make it less sticky. Mixing vegetable shortening and peanut butter at about a 50/50 ratio and then adding cornmeal or birdseed makes a very appetizing and inexpensive suet substitute that many birds love.

A bird's feet won't stick to a metal birdfeeder perch. Birds don't have sweat glands in their feet; in fact, their feet are covered in scales made from a material similar to your fingernails. Just think of all the metal fences and telephone wires birds sit on all day long without getting stuck.

This is also the time of year that people who feed birds can join the 15,000 other people who are a part of the largest and longest-running citizen-science project. Project FeederWatch is managed by the Cornell University Laboratory of Ornithology. It's a winter-long survey of birds that visit feeders at backyards, nature centers and other locales in North America. FeederWatch volunteers periodically count the highest numbers of each species they see at their feeders from November through April. The project helps scientists track movements of winter bird populations and long-term trends in bird distribution and abundance.

All you have to do is count all the birds in your yard at one time and then report the numbers to the lab. The data collected shows 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 distribution and abundance of bird species over time.

Learn more about the project at birds.cornell.edu/pfw, where you can see maps, trend graphs, and other results generated from FeederWatch data. FeederWatchers receive a research kit that includes: the FeederWatch Handbook, a guide to feeding birds; a full-color identification poster of common feeder birds; a calendar featuring photographs taken by participants; and paper data forms and/or access to the online data entry system.

Because the lab is a non-profit organization, a $15 annual participation fee ($12 for members of the Lab of Ornithology) is requested; it covers your materials and newsletter subscription, staff support, website support and data analysis. Visit the website or call 800-843-2473.
