Then, do detective work and learn more about where these birds spend the winter, and how they get to their nonbreeding ranges. Note dramatic changes in behavior, feeding habits, and plumage. An easy and enjoyable way to study birds is by placing feeders near the window of your home or classroom. Black-capped Chickadee, American Goldfinch, Northern Cardinal, and Tufted Titmouse are all common feeder birds in many parts of North America. Feeders bring birds in close so you can study their plumage and behavior.
Feeders also provide a great chance for some fun experiments.
The Cornell Laboratory of Ornithology's Project Feederwatch is a nationwide experiment to determine the feeding preferences of backyard birds. For example, one of the best ways to lure the American Goldfinch to your feeder is to provide thistle or Niger seed. Don't count on seeing Northern Cardinals at your thistle feed, however. Their preference is for sunflower and safflower seeds. Different birds also feed in distinct ways.
