Water in a bird bath or other container often attracts birds in spring and summer, but the costs of maintaining open water through the winter are not justified. Birds survive on water derived from foods they eat and from eating snow. Seed_eating birds, like crossbills, are sometimes attracted by salt and other minerals that can be supplied by a salt block. Plantings for Wildlife: If your yard has few trees and/or shrubs, birds will probably not be attracted to a feeder. Their need for shelter and protection from predators is often stronger than their attraction to an artificial food source. Also, because birds will not normally visit your yard in search of natural food if there are no trees or shrubs, they would be unlikely to detect food in your feeder. Don't despair, however! Start planning to landscape your yard for birds.
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.
