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.
Spruce and hemlock trees provide excellent cover; birch, willow, and alder provide natural seed sources, and some berry_producing plants attract birds that rarely come to feeders. A brush pile also can provide cover for some birds. For more information, read "Landscaping for Wildlife in Alaska." Types of Feeders and Where to Place Them: Different birds prefer different sorts of feeders and locations, so to get the most variety of birds, use two or more feeders. A suet feeder on a tree and a window_ or tray_feeder for seeds is the simplest combination. The feeders shown below are just examples; use your imagination to design feeders that match the landscape and architecture of your home.
