General

Long-tailed Duck: Small diving duck with black upperparts, head, neck, breast and wings; back has black and brown mottling; flanks, belly and undertail are white; tail is black with long feathers; mask is pale gray; black bill with dark pink saddle.

Range and Habitat

Long-tailed Duck: Breeds from Alaska east across most of northern Canada. Winters along the Pacific coast from the Bering Sea south to California; from Greenland, eastern North America, and Labrador south, including the Great Lakes, to South Carolina. Prefers a variety of coastal waters; straits, bays, harbors, channels, fiords, estuaries, offshore waters, and mudflats.

Breeding and Nesting

Long-tailed Duck: These ducks nest on the ground, usually near water. Five to eleven olive buff, olive gray, or green yellow eggs are laid in a hollow of grass and down, hidden in low vegetation or among rocks. Incubation ranges from 23 to 25 days and is carried out by the female. The young start to fly at 35 to 40 days.

Foraging and Feeding

Long-tailed Duck: Their diet depends on the season: predominantly aquatic invertebrates during breeding, and epibenthic invertebrates and fish in the winter. Most small prey is consumed underwater; larger items are brought to surface. They dive for food, and pick food items off the bottom or from the water column in both fresh and salt water. They drink by scooping up water with their bill.

Vocalization

Long-tailed Duck: Utters a melodious and barking, "ow-owdle-ow, ow-owdle-ow" when breeding. Noisy in all seasons; most garrulous of all North American ducks.
