Its alarm call sounds like go away, which is where its English name comes from, and it warns the rest of the savannah that a predator is about.
From Grey Go-away-bird
Its call, a descending nasal mew, is written in English as go away, and hunters detest it because it alerts antelopes and other animals to the presence of an intruder.
From Grey Go-away-bird
It belongs to the only group of turacos that has left the forest for the open savannah, and as a result has lost the green and red pigments of its family: it is entirely grey.
From Grey Go-away-bird
Its green is turacoverdin, a copper-bearing pigment found only in its family: the only genuine green pigment in the bird world.
From Knysna Turaco
Its red wing pigment, turacin, also contains copper and is water-soluble: zoos have documented turaco bathing water turning pink.
From Knysna Turaco
It moves through the canopy by running along the branches rather than flying, and its flight is short, heavy and direct, with a burst of red as it opens its wings.
From Knysna Turaco
Its green is a real pigment called turacoverdin, with copper in the molecule, and it is the only true green pigment in the bird kingdom: in every other species green is an optical effect of the structure of the feather.
From Guinea Turaco
Its red, turacin, also contains copper and is soluble in alkaline water: a wet feather can turn the water pink, something that baffled nineteenth-century naturalists.
