Harlequin Duck

The brilliant, fragmented pattern of this duck's plumage is a subtle camouflage against clear, moving waters. The Harlequin breeds beside cold, fast-flowing streams and rivers, feeding on the aquatic insects that cling to rocks and shingle. It flies strongly and low, following watercourses. After breeding it migrates to the sea, where it dives for shellfish, crustaceans, and other food.
