Bird Brains
Set up three bird feeders near a window, and fill them each with a different type
of feed, such as sunflower seeds, cracked corn, and millet. Track what kinds of birds
(and other creatures!) visit which feeders. Does weather make a difference?
What other factors affect how many birds come to your feeders? If you want to participate in a national study of birds, visit the Cornell Lab of Ornithology Web site.
