Potoo is a nocturnal bird native to the tropical Americas, notable for its large, wide mouth and camouflaged plumage. Used in ornithology and nature writing, it often stands motionless, blending with branches. As a noun, it refers to the bird itself and, in some contexts, to any long-billed insectivore of the family Nyctibiidae. The term is commonly encountered in field guides and wildlife discussions.
