DESCRIPTION

Front view

The yellow-shouldered amazon is mainly green and about 33 cm long. It has a whitish forehead and lores, and a yellow crown, ocular region and - often - ear coverts and chin. The bare eye-ring is white. The thighs and the bend of the wing ("shoulder") are yellow, but both can be difficult to see. The throat, cheeks and belly often have a bluish tinge. As most members of the genus Amazona, it has broad dark blue tips to the remiges and a red wing-speculum . Its beak is horn coloured.

In its range the yellow shoulder patch and extensive yellow on the head distinguish the yellow-shouldered amazon from other Amazona species, which have red or orange on the shoulder and less yellow on the head (the orange-winged amazon , which has as much yellow to the head as some yellow-shouldered amazons, has a blue ocular region). However, outside its range, several other Amazona species have as much - or more - yellow on their heads.
