Common name: Bufflehead
Scientific name: Bucephala albeola
Diet: Omnivorous; mainly aquatic invertebrates
Average life span: 2.5 years
Length: 32-40 cm
Weight: 272-635 g
Food & Habitat
They breed near lakes in northern forests, most often in mixed deciduous and coniferous forest.
Bufflehead dive for aquatic invertebrates, crustaceans, and mollusks. They dive for on average 12 seconds, and surface another 12 seconds or so before diving again. They usually swallow their food while still underwater. They eat some plant matter in fall and winter, primarily seeds of bulrushes and pondweeds. Downy ducklings occasionally dabble at the surface rather than diving.
Breeding & Population
Like its close relative, the common goldeneye, the bufflehead nests in cavities in trees close to water, often in the abandoned homes of flickers and other woodpeckers. Females lay a clutch of 4-17 eggs.
Bufflehead can be found across western Canada, and as far north as Alaska.
Their wintering grounds include the west and south of the United States and the northernmost parts of Mexico.
- The name “bufflehead” is derived from “buffalo-head”, for the male’s distinct and puffy head shape.
- The bufflehead is less sociable than most ducks, seen in pairs or small groups, but almost never in large flocks.
