The lilac-crowned amazon (Amazona finschi) is a parrot endemic to the Pacific slopes of Mexico. Also known as Finsch's amazon, it is characterized by green plumage, a maroon forehead, and violet-blue crown and neck.
The binomial of this bird commemorates the German naturalist and explorer Otto Finsch.
The plumage of an adult lilac-crowned amazon is primarily green with yellowish underparts and black edging. The forehead is a maroon color 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 coloring. Furthermore, the initial five secondary feathers have a bright red speculum on the edge of the feathers. The wing coverts, underside of the flight feathers, and the tail are green while the tail is tipped with a yellowish coloring similar to that of the cheeks and ear coverts. Their beak, orbital rings, and legs are a palebrown-grey coloring. The irides of adult lilac-crowned parrots are amber colored.
Juvenile lilac-crowned amazons are visually similar to their adult forms except for minor differences. One difference is that the iris of juveniles are a dark brown as opposed to the amber coloring that is found in adults. The other major difference is that there less maroon colored feathers on the forehead of juveniles. After about one year juveniles begin to acquire these adult features.
