Species Description:
The Harlequin Duck (Histrionicus
histrionicus) is a small sea duck. The male has a slate blue
body accented with white and black markings and chestnut flanks.
Females are a dull brown with three white spots on the sides
of their heads. Harlequins breed on turbulent, upland rivers
and streams and winter along rugged coastlines. In spring they
congregate at river mouths and estuaries, waiting for the rivers
to thaw. Except when breeding, Harlequins are gregarious, feeding,
molting and wintering on traditional grounds in flocks.
Distribution:
The eastern population of the Harlequin
Duck breeds in northern Québec, Labrador, Newfoundland’s
Great Northern Peninsula, southeastern Newfoundland, and the
eastern tip of the Gaspé Peninsula. In all likelihood
Harlequin Ducks are also breeding on Baffin Island, Nunavut and
the northern extremes of New Brunswick. Harlequins winter along
the rugged coasts of southern Newfoundland, the Atlantic Coast
of Nova Scotia, in the Bay of Fundy off New Brunswick, the Gulf
of Maine to as far south as the mouth of the Chesapeake Bay.
Threats:
The eastern population of the Harlequin
Duck was listed as endangered by the Committee on the Status
of Endangered Wildlife in Canada (COSEWIC) in 1990 because its
numbers have declined to a point below minimum viable population
size. However, in the spring of 2001, Harlequin Ducks were downlisted
to Species of Special Concern as COSEWIC viewed the population
increase and present positive population trend as sufficient
to take them off the endangered list. Nonetheless, their habit
of staging, molting, and wintering in flocks in traditional areas
leaves the species vulnerable to human disturbance, and oil pollution.
Its breeding habitat is threatened by a variety of disturbances
including hydroelectric development, forestry, insect control
programs, low-level military flying, resource development and
increased access by humans. Illegal hunting, whether accidental
- females and immature Harlequins are difficult to differentiate
from some legally hunted species - or deliberate, takes it toll
on a species that has a naturally low reproductive rate.
Summer Range
Breeds from Alaska to northwestern
Wyoming, and from northern Quebec and Labrador to northern New
Brunswick. Also in Greenland, Iceland, and Siberia.
Winter Range
Winters along Pacific Coast from
Alaska to northern California, and along Atlantic Coast from
Newfoundland to New Jersey. Also in Greenland, Iceland, and along
Pacific Coast southward to Japan.
Habitat
Mountain streams and rivers, usually
in forested regions; in winter, primarily turbulent coastal waters,
especially in rocky regions.
Food
Insects, fish, and marine invertebrates.
