Winter is a quiet season for birds in Alaska. Most migrate south to wintering areas in the Lower 48, Mexico, South America, and Polynesia. But, some species remain in Alaska through the winter. Even in the northernmost regions of Alaska, some ravens, snowy owls, and gyrfalcons remain, and offshore, murres and a few gulls linger near openings in the pack ice. Over 25 species endure the harsh winters of interior and western Alaska, and over 100 stay through the milder coastal winters of southcoastal and southeastern Alaska.
Build a box that will stay dry and warm. Place the roof of a birdhouse at a slight angle and extend it over the sides and front of the box. In this way, the roof will shed rain or snow and protect the entrance hole and sides from dripping water. Drill four, 1ǚ_inch holes in the floor to provide drainage if water seeps in. The sides of a nest box should extend down beyond the floor so water won't leak in.
