Tufted Duck

A slender crest dangling over the nape identifies this diving duck. Naturally a bird of deep, open water on lakes and rivers, it has adapted itself to live in built-up areas. Of all the birds seen in an urban setting, the lufted Duck is unicpie for two features: males have black plumage with white sides and bellies, and both sexes have yellow, button eyes. Tufted Ducks swim well underwater, sometimes to depths of 45 ft (14 m), and feed on a wide range of tiny aquatic animals and plants.
