Resident from portions of Alaska and western Canada, south in mountains to southwestern South Dakota, and further south to southern California, highlands of Mexico, and western Panama.
Found up to treeline along montane streams, especially along swift-flowing water. Found less frequently along mountain ponds and lakes. In winter, occasionally found along rocky seacoasts.
Feeds on adult insects and their larvae (e.g., caddisflies, stoneflies, mayflies, mosquitos, and water beetles). Also eats clams, snails, and some trout fry.
Solitary except during nesting season. Nests on rock in stream, on cliff face, or behind waterfall. Adapted for semi-aquatic foraging. Walks, swims, or dives in or under water, and walks on stream bottoms while foraging. Characteristic dipping behavior upon alighting may signal mate.
