Natural history and behavior
Select one species to observe and study in detail. Research this bird’s natural history and behavior both by watching and by reading. What time of day does the species visit your feeder? Do individuals visit alone or in flocks? Where does the bird find its food when not at your feeder? Where does it sleep? Where does it live during summer? What kind of nest does it build? Observe its behavior at your feeders. Does the bird flutter or droop its wings, pass food back and forth, make raucous sounds, or chase other birds?

Art
Sketch the birds at your feeder, using binoculars to make detailed observations. Include field marks such as the curve of the bird’s bill, its eye ring, and its crown, cheek, or ear patch. Compare your sketches to photos and illustrations in field guides.

Bird songs and calls
Many birds make two kinds of sounds: songs and calls. Songs are used almost exclusively by males to attract females and to defend territories. Calls are used by both sexes to express alarm and to maintain contact. Most birds don’t sing at feeders in winter, but they often make calls or "chip" notes. Listen carefully to these and try to learn the sounds of each species. You also can listen to recordings of actual bird songs and calls; check out the Sound of the Week web page, or visit your local library for cassettes or CDs.

Journaling
The suggested activities all require careful observation and notekeeping. Try starting a journal with detailed observations of the birds at your feeder site. Even if you don’t yet know a bird’s name, describe what you see. Include the date of your observation, the location, the weather, the species’ name if you know it, and an overview of the bird’s appearance, behavior, and sounds.

Weather
Does weather influence how many birds come to your feeders, or how much food they eat? Look separately at the variables of wind, rain, temperature, and barometric pressure. Investigate why one factor might make a difference to the birds and another one might not.

Math
Weigh the birdseed in your feeder before and after each FeederWatch Count Day and compute how much seed was eaten. After several timed counts, calculate the average consumption rate of your feeder birds. Predict and then test how often your feeders need to be refilled. What variables—weather, time of day, different seeds—confound these predictions?

Computer connections
Your studies need not be confined to your backyard; because of the Internet, you also can study birds as an extended group. For example, in the summer of 1999, a group of Project FeederWatchers conducted their own seed preference study. This diverse group, with members from Washington State to Massachusetts and many places in between, was brought together by the FeederWatch listserv (the Classroom FeederWatch listserv could serve a similar purpose). After comparing notes about the seed preferences of birds at their home feeders, they decided to conduct their own study to determine whether their birds preferred black-oil sunflower or safflower seed. They really put their Feeder-Watching to the test!
