A two-part crick-crick. Heard most often during breeding season, but also heard occasionally during winter.
Breeds mainly from western Canada, east to southwestern Manitoba, and south through U.S. from California and Utah east to upper midwestern states. Winters mainly along Pacific Coast from southeastern Alaska to northwestern Mexico.
Diet consists mainly of fishes; opportunistic as to species eaten. Also eats insects (adults and larvae, especially in spring and summer), mollusks, crabs, marine worms, and salamanders. Ingests feathers and small stones.
Builds platform nest on shallow water. Nests in colonies of sometimes hundreds or thousands of birds. In Idaho, nests in large colonies and isolated pairs that are susceptible to water fluctuations. Young may ride on backs of adults. Individuals dive from water surface to obtain food.
