The orange-winged amazon is a mainly green parrot about 33 cm long and weighs about 340g. It has blue and yellow feathers on its head which varies between individuals. The upper mandible is partly grey coloured and partly dark-grey. It has orange feathers in the wings and tail, which can be seen when in flight. The male and female are identical in external appearance.
The orange-winged amazons are noisy birds and makes loud, high-pitched screams. They feed on fruit and seeds, including the fruit of palm trees and sometimes cocoa. It roosts communally in palm and other trees, and large numbers can be seen at the roost sites at dawn and dusk.
Although common, it is persecuted as an agricultural pest and by capture for the pet trade (over 66,000 captured from 1981 to 1985). It is also hunted as a food source.
