Description[edit]
The African grey parrot is a medium-sized, predominantly grey, black-billed parrot which weighs 400 g, with a length of 33 cm[2] and an average wingspan of 46–52 cm.[3] The tail and undertail coverts are red, in comparison to the maroon of the smaller Timneh parrot. Both sexes appear similar.[2]
The colouration of juveniles is similar to that of adults, however the eye is typically dark grey to black, in comparison to the greyish-yellow eyes of the adult birds. The undertail coverts are also tinged with grey.[2]
African grey parrots are long-lived birds that may live for 40-60 years in captivity, although their mean lifespan in the wild appears to be somewhat shorter at ~23 years.[3]
