The Louisiana waterthrush (Parkesia motacilla) is a New World warbler, that breeds in eastern North America and winters in the West Indies and Central America. Plain brown above, it is white below, with black streaks and with buff flanks and undertail, distinguishing it from the closely related northern waterthrush. The habitats it prefers are streams and their surroundings, and other wet areas. The Louisiana waterthrush has a plain brown back and white underparts streaked with black. The flanks and undertail are buff. There is a strong white flared supercilium, and the legs are bright pink. All plumages are similar, but young birds have buff underparts rather than white. The main confusion species is the closely related northern waterthrush (Parkesia noveboracensis), which has white flanks and undertail, a striped throat, a slightly smaller bill, a shorter supercilium and duller pink legs.
