A bird of fast-moving water, the Harlequin Duck breeds on fast-flowing streams and winters along rocky coastlines in the crashing surf.
More than half of eastern North American population of Harlequin Ducks winters in coastal Maine, particularly outer reaches of Penobscot and Jericho bays.
When engaged in behavioral interactions, the Harlequin Duck gives distinctly unducklike squeaks, the source of one of its local names: sea mouse.
