Description
Subspecies in the nominate group (including subspecies xantholaema, nattereri and panamensis) have a total length of 33–38 cm (13–15 in). As most other Amazon parrots, it has a short squarish tail and a primarily green plumage. It has dark blue tips to the secondaries and primaries, and a red wing speculum, carpal edge (leading edge of the wing at the "shoulder") and base of the outer tail-feathers. The red and dark blue sections are often difficult to see when the bird is perched, while the red base of the outer tail-feathers only infrequently can be seen under normal viewing conditions in the wild. The amount of yellow to the head varies, with nominate, nattereri and panamensis having yellow restricted to the crown-region (occasionally with a few random feathers around the eyes ), while the subspecies xantholaema has most of the head yellow. All have a white eye-ring. They have a dark bill with a large horn or reddish spot on the upper mandible except panamensis, which has a horn coloured beak. Males and females do not differ in plumage. Except for the wing speculum, juveniles have little yellow and red to the plumage.
