It has darker grey over the head and both wings, while the head and body feathers have a slight white edge to them. The tail feathers are red. Due to selection by parrot breeders, some grey parrots are partly or completely red. Both sexes appear similar.

The undertail coverts are also tinged with grey. The adults weigh 418–526 grams 0.922–1.160 lb
