Winter Roost Boxes. Chickadees, owls, and woodpeckers that remain in Alaska during winter use natural tree cavities and birdhouses as roosting sites. These roosting sites provide protection from wind and snow and extra insulation against the cold. Any birdhouse can provide a winter roost site if it is properly built, but better insulated birdhouses can also be constructed. Try placing perches on the inside of a birdhouse. During severe cold several chickadees sometimes share their body heat by roosting together in a single cavity.
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.
