The most distinctive features of this primarily green parrot are its yellow head and the red patch, or speculum, on each wing, which are lacking in young birds but become more prominent with age (3). There are also dark blue tips to the flight feathers and yellow tips to the tail, with red marks on the base of the outer tail feathers (2). The stout, hooked beak is used for cracking nuts and seeds as well as for grasping and climbing, and the feet are also highly adapted for grasping, having two toes pointing forward and two pointing backward (3).
