The great blue turaco (Corythaeola cristata) is a bird species of the family Musophagidae. At 70–76 cm (28–30 in) in length, it is the largest species of turaco. It has predominantly grey-blue plumage with an upright blue-black crest around 10 cm (3.9 in) high. The male and female have similar plumage. It is widespread throughout the African tropical rainforest.
The species ranges from Guinea in the west, east across the sub-Saharan nations to the Imatong Mountains in South Sudan; it also occurs in Uganda, Tanzania and western Kenya, south to the Democratic Republic of Congo and Angola. It inhabits rainforests and gallery forests. It has also adapted to areas cleared by humans and can thrive in these areas.
The great blue turaco is gregarious, with birds forming small troops of some six or seven individuals.
