Sometimes placed in genus Hypoleucos. Long referred to as P. olivaceus, but brasilianus has priority#R; P. olivaceus thus a junior synonym. Proposed race chancho (Sonora, in NW Mexico) is synonymized with mexicanus, and hornensis (S Chile) with nominate. Two subspecies normally recognized.

Subspecies and Distribution
  • P. b. mexicanus (J. F. Brandt, 1837) – S USA (S Arizona to Louisiana) S to Panama, also Bahamas and Cuba; populations above 27° N disperse towards S.
  • P. b. brasilianus (J. F. Gmelin, 1789) – Panama and S throughout most of South America to Cape Horn.
