histrionicus
Uncommon in fast-moving streams at moderate elevations in mountains of eastern King and western Kittitas Counties. Generally breeds on rivers with closed forest canopies, situating nests on banks in dense cover, but may also use rock crevices and tree cavities. Often roosts on gravel bars in rivers during breeding season. Non-breeders and post-breeding males found by early summer along seacoast, or rarely in large lakes.
