Subspecies
Currently accepted subspecies are doubtfully valid, and perhaps represent merely extremes in broad geographical size trends and individual plumage variation.
The following 2 subspecies are recognised:
guatemalensis Land & Schultz, 1963 - Extreme southern Mexico, Guatemala, and possibly Honduras.
grandis (Gmelin, JF, 1789) - Nicaragua to northern South America, where mostly east of Andes throughout Amazonia to northern Paraguay, and in south-eastern Brazil; may occur locally between Amazonia and Atlantic forest regions.
