The Bufflehead ranges from 32-40 cm long and 0.6-1.2 lbs, with the drakes larger than the females. Averaging 35.5 cm and 13 oz, it rivals the Green-winged Teal as the smallest American duck. Adult males are striking black and white, with iridescent green and purple heads with a large white patch behind the eye. Females are grey-toned with a smaller white patch behind the eye and a light underside.
They are migratory and most of them winter in protected coastal waters, or open inland waters, on the east and west coasts of North America and the southern United States. Their breeding habitat is wooded lakes and ponds in Alaska and Canada.
