The Chestnut-eared Aracari (Pteroglossus castanotis) is a species of bird belonging to the Toucan and Aracari family Ramphastidae. It is native to central and south-eastern South America. The actual range of this species is the southern Amazon Basin, especially the southwestern of this region. It is also found in the eastern Andean foothills. A narrow range extends into central-southern Colombia by 550 miles.
The southern Amazon Basin range narrows in the southeast to only the upstream half-headwaters of the north-flowing Amazon River tributaries. This range continues southeast into the central and southern Cerrado (a vast tropical savanna ecoregion in Brazil) and ends in the ParanÃ¡ River region in eastern Paraguay, southeastern Brazil and the extreme northeast of Argentina.
