The American dipper (Cinclus mexicanus), also known as a water ouzel, is a semiaquatic bird species native to western North America. The American Dipper is found on fast-flowing mountain streams and cold coastal streams of western North America and Central America. They forage in cascades, riffles and waterfalls along unpolluted waterways. Dippers feed principally on aquatic larvae of insects like mayflies, mosquitoes, and caddisflies. They also eat dragonflies, worms, small fish, fish eggs, tadpoles and small shrimp-like crustaceans called amphipods. The song of the American Dipper, given by both sexes, is a sweet, burbling medley of single and repeated notes. They sing loudly to rise above the background noise of rushing water. Bouts of singing may last up to 10 minutes. The American Dipper has a short, burry jik call, given in bursts of two to five repeats. Here is a link so you can listen to this bird as well.
