Psittacara erythrogeny is native to the southwestern coastal lowlands of Ecuador and northwestern Peru, where it inhabits dry forests, scrub, and semi-open areas, often nesting in cliffs, tall trees, or crevices. It has also established feral populations outside its natural range in cities across central and southern California, as well as in urban and suburban areas of Florida. These introduced populations are sustained by escapees and released birds, especially in metropolitan areas with abundant palm trees and mild climates. The species is classified as Near Threatened due to habitat degradation and capture for trade in parts of its native range.

Adults reach approximately 13 inches in length and have a green body with a prominent red forehead, lores, and variable red markings on the cheeks and throat. Some individuals show red feathers scattered on the shoulders or wings. The tail is long and tapered, with a green upper surface and duller underside. Psittacara erythrogeny is a highly social species, forming flocks that can number in the hundreds. It is known for its loud, harsh calls during flight and at communal roosting sites. Breeding season varies geographically, but the species typically nests in cavities, including arboreal termite mounds and hollow palms.

The species is bred and sold in the international pet trade, particularly in the United States and parts of Europe. It maintains a presence in the hobbyist market due to its vocalizations, social behavior, and ability to mimic sounds. Photographed in Ecuador.
