The following information is meant to help you build birdhouses suitable for Alaskan birds. More information on birdhouses can be found at your local library or bookstore. Birds that nest in cavities are the only ones attracted to nest boxes. In Alaska, 30 bird species nest in cavities, and 21 of these will use birdhouses. Excepting Snow Buntings, which nest in natural and man_made cavities in tundra areas, most cavity_nesting birds prefer to nest in holes in trees.
Predator Protection: Backyard predators that threaten bird houses can include pets, stray cats, raccoons, rats, squirrels, snakes, mice and even stinging insects. Other bird species may also kill or injure baby birds and their parents either for a meal food or to take over the house for their own nesting site. To make a bird house safe from predators. Remove any perches from the house: Birds do not need them to access the house, and perches only provide convenient handholds for predators. At the same time, remove any nearby branches that could also provide a way for predators to access the house.
