Dipper
Dippers are members of the genus ''Cinclus'' in the bird family Cinclidae, named for their bobbing or dipping movements. They are unique among passerines for their ability to dive and swim underwater. ==Description==
Dippers are small, chunky, stout, short-tailed, short-winged, strong-legged birds. The different species are generally dark brown (sometimes nearly black), or brown and white in colour, apart from the rufous-throated dipper, which is brown with a reddish-brown throat patch. Sizes range from 14–22 cm in length and 40–90 g in weight, with males larger than females. Their short wings give them a distinctive whirring flight.〔Whistler, Hugh. (2007).

Western Publishing Company: New York.〕 They have a characteristic bobbing motion when perched beside the water, giving them their name. While under water, they becomes covered by a silvery film of air, due to small bubbles being trapped on the surface of the plumage.〔(The Dippers )〕
