Brown Creeper:  This tiny woodland bird eats mostly insects, but in winter at a backyard feeder they will eat suet, peanut butter, and occasionally sunflower seeds and corn. During the breeding season, Brown Creepers eat a long list of insects and their larvae. This includes stinkbugs, fruit flies, gnats, beetles, weevils, bark beetle, butterflies, moths, lacewings, caddisflies, scale insects, leafhoppers, katydids, flat-bugs, plant lice, ants, and sawflies along with spiders, spider eggs. Brown creepers are found throughout Oregon in forested areas. They use large conifer forests for foraging and breeding, but they need dead trees for nesting, because they build a hammock-like nest behind a flap of dead bark.
