Position the bird house far enough away from brush so predators cannot stage an ambush, but close enough to plants so parent birds can easily scout the area. Five to eight feet of distance is sufficient for most bird houses. Similarly, keep bird houses away from popular feeding areas to prevent territorial conflicts between feeding birds and nesting parents. Choose natural colors so the bird house will blend into the surroundings: Browns and dark shades of green are the most suitable choices and will be the most attractive to birds. If desired, decorate the house with natural materials to keep it concealed but still an ornamental focal point in the yard.
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.
