Range - Mountains of western North America from Alaska to Central America.

These short-tailed, grayish colored birds are among the strangest of feathered creatures; they frequent the sides of mountain streams where they feed upon aquatic insects and small fish. Although they do not have webbed feet, they swim on or under water with the greatest of ease and rapidity, using their wings as paddles. They have a thrush-like bill and the teetering habits of the Sandpiper, and they are said to be one of the sweetest of songsters. They nest among the rocks along the banks of swiftly flowing streams, and sometimes beneath falls; the nests are large round structures of green moss, lined with fine grass and with the entrance on the side. The eggs are pure white, four or five in number, and laid during May or June. Size 1.00 x .70.
