Bufflehead

Bucephala albeola

Length: 14 to 16 inches Wingspan: 20 to 24 inches Seasonality: Migrant
ID Keys: Large white patch on back of head, black back and remainder of head, white body

Bufflehead - Bucephala albeolaOne of the smallest ducks found in the state, the Bufflehead can be distinguished by the male's large white patch on the back of its otherwise black head.  Its small size allows it to use nest cavities of Flickers and other similarly sized cavities, giving it an ample supply of nesting locations. They are a diving duck, feeding underwater. As with many duck species in the United States, populations have rebounded strongly in recent decades.

Habitat: Prefers small ponds and lakes with surrounding woodland for breeding.  Winters on small ponds, lakes, and rivers inland, also in shallow bays and estuaries along the coasts.

Diet: Primarily insects and insect larvae in the summer.  Primarily crustaceans and mollusks in the winter.  Also will occasionally eat plant material.

Behavior: Nearly always feeds by submerging and obtaining food underwater.  Buffleheads are not as gregarious as many ducks, and are often found in pairs or small flocks.

Nesting: June and July in their North American Range.  Buffleheads are cavity nesters, typically using old burrows of woodpeckers or other burrows when available (including nest boxes).  They are monogamous, with birds often returning to the same nesting location year after year. The female lays between 7 and 10 eggs, and she alone incubates them. The eggs hatch after about 4 weeks. The young leave the nest only a day after hatching, and may be tended to by the female as they grow, but the young find their own food.

Song: Squeaky whistling and low grumbling.

Migration: Summers primarily in Canada and Alaska.  Winters along North American coasts, throughout much of the southern half of the U.S., and points south.

Similar Species: Hooded Merganser perhaps, as it shares the same kind of large white patch on the back of the head. However, the Bufflehead's size, plumage, and unique shape make it a rather easy species to identify if it's seen well.

Birdhouses: Will use appropriately sized nest boxes near water.

Conservation Status: As with many waterfowl species in the United States, conservation efforts, reasonable hunting regulations, and restoration of habitat has led to a strong increase in populations over the last few decades. Bufflehead are common in many parts of a very large range.  The IUCN considers the Bufflehead as a species of "least concern".
