The chestnut-eared aracari (US /ˌɑːrəˈsɑːri/ ahr-ə-sahr-ee, UK /ˌɑrəˈsɑːri/ arr-ə-sahr-ee or /ˌɑrəˈkɑːri/ arr-ə-kahr-ee), or chestnut-eared araçari (Pteroglossus castanotis), is a bird native to central and south-eastern South America. It belongs to the toucan and aracari family (Ramphastidae). P. castanotis is a larger, more colorful bird than the black-necked aracari (P. aracari), which it otherwise resembles.
The range of the chestnut-eared aracari is the southern Amazon Basin, especially the southwestern of this region. It is also found in the eastern Andean foothills; a narrowing range extension enters central-southern Colombia by 900 kilometres (560 mi). source
