Bestimmung

The plumage of an adult lilac-crowned amazon is primarily green with yellowish underparts and black edging.The forehead is a maroon colour with a light blue-lilac neck, nape, and crown.The cheeks and ear coverts are a greenish yellow that lacks the edging that is present in most of the plumage.The primary feathers are dark blue with the secondary feathers being green while being tipped with the same dark blue colouring.Furthermore, the initial five secondary feathers have a bright red speculum on the edge of the feathers.The wing coverts, the underside of the flight feathers, and the tail are green while the tail is tipped with a yellowish colouring similar to that of the cheeks and ear coverts.Their beak, orbital rings, and legs are a pale brown-grey colouring.The irides of adult lilac-crowned parrots are amber-coloured.<p>Juvenile lilac-crowned amazons are visually similar to their adult forms except for minor differences. One difference is that the iris of juveniles is a dark brown as opposed to the amber colouring that is found in adults.The other major difference is that there less maroon coloured feathers on the forehead of juveniles. After about one-year juveniles begin to acquire these adult features.

Verbreitung und Lebensraum

The lilac-crowned amazon's endemic range spans along the pacific coast of Mexico, beginning in southeastern Sonora and southwestern Chihuahua down to southern Oaxaca. In Sinaloa and northern Nayarit the geographic range of the lilac-crowned parrot is above 375 meters of elevation; the range does not descend to sea level until southern Nayarit, where it remains so through Jalisco and Oaxaca.<p>The lilac-crowned amazon's natural habitat in Mexico is often threatened. The decline in population size has been recorded in almost all of its natural habitat locations. Based on a collection of data and resident accounts, Amazona finschi population range has decreased by 20% due to habitat loss.<p>An increasingly growing population of approximately 100 individuals is found in Southern California, especially in the San Gabriel Valley and Orange Country.This increase could also be attributed to a more reliable source of measurement of population than in past years. These populations often are found in residential areas and occasionally in nesting groups with red-crowned parrots in native conifer forests or non-native captive plants.
