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.
To prevent the spread of some avian diseases, food should not be spread on the ground, and feeders should be cleaned and disinfected regularly. Other Attractions for Birds.Birds do not have teeth; instead, they grind food in their gizzards. Birds eat small pieces of sand and gravel, or "grit" to aid the grinding process. In winter, when the ground is covered by snow, suitable grit may be hard to find. You can supply grit to birds at the feeder in the form of crushed eggshells, coarse sand, or from boxes of grit that are sold at variety and pet stores.
