Height 48 in. They are so named because they spend their summers in the tundra regions of Alaska and Canada. Tundra swans primarily feed on aquatic vegetation found in shallow water.
Tundra swans form strong, permanent, monogamous relationships.
During the brief Arctic spring, breeding females build their nests out of sedge and moss, lining them with down to insulate their eggs from the cold. They usually lay from 4 to 6 creamy white eggs, which they incubate for 35 to 40 days. In the fall, large numbers of tundra swans migrate from the Arctic to North Carolina and other locales along the Atlantic Coast. T hey fly in flocks of several hundred, making mellow bugling calls to each other. Tundra swans make many stops along their migration route.
