Distribution and habitat
This species lives in riparian forest and areas with trees, as well as evergreen forest in Belize and mangroves in Guatemala. A notable ecoregion of occurrence is the Belizean pine forests. It occurs singly or in pairs, in small groups, and in big flocks. The range formerly included both coastal slopes of Mexico from the Tres Marías Islands and Jalisco to Oaxaca and from Nuevo León to northern Chiapas and southwestern Tabasco, as well as a disjunct area including most of Belize, and another comprising a small part of northeastern Guatemala and northwestern Honduras. 
Introduced populations can be found in Stuttgart, Germany where a population of over 50 individuals resides. Smaller introduced populations are to found at Imperial Beach, Santa Ana, Loma Linda and Pasadena; all in Southern California. In addition, introduced –and apparently breeding– populations have been reported in Puerto Rico.

Their vocal abilities are generally bested only by the grey parrot and matched by similar parrot species, Yellow-headed amazons in captivity appear to have an affinity for both singing and the learning of songs - and a naturally powerful, operatic voice
