Some salamander species occur only in fast mountain streams; other species are more typical of pond-like pools. The belted kingfisher feeds on stream fishes, and nests in adjacent clay banks. In the western mountains, the water ouzel feeds under water on the insect larvae and naiads of the riffles. Muskrats make their bur- rows in the stream banks and feed on vegetation and clams. Mink patrol the streams for the muskrats and fish that serve them as food. The once-abundant otter is now absent from most localities. Beaver dam streams to enlarge the pools in which they build their lodges and find shelter. Beaver feed on the bark and cambium of aspen, willow, and other trees and shrubs occurring on the shores of the stream. ADJUSTMENTS TO CURRENT Probably the characteristic of a stream most critical to the life therein is the current. All organisms that occur in streams must adjust to it to maintain constant position. Torrential floods scour.
