The common potoo, grey potoo, lesser potoo or poor-me-one (Nyctibius griseus), is a nocturnal bird which breeds in tropical Central and South America from Nicaragua to northern Argentina and northern Uruguay. The northern potoo (N. jamaicensis) was formerly classified as a subspecies of this species. The single egg is white with lilac spots. It is laid directly in a depression in a tree limb, usually some meters above ground. It is not clear whether there can be, on occasion, two eggs in a clutch. This widespread species is not considered threatened by the IUCN.
