The eared quetzal (Euptilotis neoxenus), also known as the eared trogon, is a near passerine bird in the trogon family, Trogonidae. It is native to streamside pine-oak forests and canyons in the Sierra Madre Occidental of Mexico south to western Michoacán and southeasternmost Arizona in the United States. This range includes part of the Madrean Sky Islands region of southeastern Arizona, southwestern New Mexico, and northern Sonora.
The male's song (tremolo call) is a series of whistled notes increasing in volume. Calls include low-intensity squeals rising in pitch, a loud squeal ending with a sharp "chuck", and a strident cackle given mostly in flight.
