African Grey Congo

Bird

Congo African Grey Parrot (Psittacus erithacus erithacus): This is the nominate subspecies, larger than the Timneh at about 33 cm (13 in) long, with light grey feathers, cherry red tails, and an all black beak. Immature birds of this subspecies have tails with a darker, duller red towards the tip (Juniper and Parr 1999) until their first moult which occurs within 18 months of age. These birds also initially have grey irises which change to a pale yellow colour by the time the bird is a year old. The Congo grey parrot is found on the islands of Príncipe and Bioko and is distributed from south-eastern Ivory Coast to Western Kenya, Northwest Tanzania, Southern Democratic Republic of the Congo (DRC) and Northern Angola. In aviculture, it is often called a "CAG".
