Fruit_eating birds, such as pine grosbeaks and Bohemian waxwings, are rarely attracted to feeders, but when snow covers most natural berries, wild cranberries, blueberries, or dogwood berries occasionally attract these colorful species to a feeder. Gray jays, Steller's jays, black_billed magpies and common ravens eat a wide variety of foods. Sliced apple halves and leftover table scraps may divert their attention from the suet long enough to give smaller birds a chance. Be careful not to give moldy food to birds, however, as it may cause illness or death.
Snags with old woodpecker holes provide homes for swallows, chickadees, nuthatches, bluebirds, owls, and other cavity_nesting birds that are rarely able to excavate their own nest sites. Snags provide ideal hunting perches for Red_tailed and Rough_legged Hawks, Bald Eagles, Hawk Owls, Great_horned Owls, and other raptors. Snags provide "songposts" to a wide variety of birds. Many small birds use songposts sticking above other vegetation to sing (to attract mates and proclaim nesting territory boundaries) and to perch on when looking out for predators and/or other birds.
