Harlequin Duck
(Histrionicus histrionicus)
Harlequin Duck
The Harlequin duck range is found mainly
in northwestern Montana and the Greater
Yellowstone Ecosystem. Harlequin ducks
inhabit fast moving, low gradient, clear
mountain streams. Conservation concerns
include: range and forest management
practices; human disturbance during
breeding season; and water pollution on
headwater streams utilized for nesting,
brood rearing and prey base. Conservation
strategies include: managing grazing to
preserve riparian vegetation and streambank
stability; decreasing human disturbance
such as boating, hiking and camping during
breeding season; and working with cooperators
and public to identify and reduce point source
pollution in headwater streams.
