Harlequin Duck
Histrionicus histrionicus
The Harlequin Duck is a small duck of fast streams and rivers in the summer, and pounding coastal waters in the winter. Studies on the species have shown that many adult birds have suffered broken bones in their past, obviously due to their preferred habitats. They are generally only short distance migrants from the summer breeding locations, and thus are only very rare visitors to the deep interior of the continent. The Birds of South Dakota (SDOU, 2001) lists only a single documented case of the species in South Dakota. The bird on the right is the 2nd documented case, found the weekend of November 8th, 2003.
Habitat: In summer, they are found along fast moving streams and rivers, often in forested lands of Canada, Alaska, and the extreme U.S. Northwest. During migration and winter, they are mostly found on the ocean, often in extremely rough coastal waters.
Diet: Primarily mollusks, crustaceans, and insects. Will also feed on marine worms, small fish, and a small amount of plant material.
Breeding: Non-breeder in South Dakota
Song: Usually silent, but both sexes have low croaks, and the male has quite squeaks during courtship.
Migrations: Summers in Alaska, western Canada, and locally in the Northwest U.S., as well as locally in eastern Canada. Winters along the Pacific and Atlantic coastlines, generally from the northern U.S. and along Canada and Alaska.
Similar Species: The male is generally unmistakable, but the female is somewhat similar to a female Bufflehead.
Status: Populations in the western part of North America are generally stable, but eastern populations have declined substantially since 1900.
