The turacos make up the bird family Musophagidae (/ˌmjzˈfæɪd/ "banana-eaters"), which includes plantain-eaters and go-away-birds. In southern Africa both turacos and go-away-birds are commonly known as loeries. They are semi-zygodactylous: the fourth (outer) toe can be switched back and forth. The second and third toes, which always point forward, are conjoined in some species. Musophagids often have prominent crests and long tails; the turacos are noted for peculiar and unique pigments giving them their bright green and red feathers.

Traditionally, this group has been allied with the cuckoos in the order Cuculiformes, but the Sibley-Ahlquist taxonomy raises this group to a full order Musophagiformes. They have been proposed to link the hoatzin to the other living birds,[1] but this was later disputed.[2] Recent genetic analyses have strongly supported the order ranking of Musophagiformes.[3][4][5]

Musophagidae is one of very few bird families endemic to Africa.[6] Another order, which is also endemic to Africa are the mousebirds, Colliidae. All turaco species are frugivorous, but they also eat leaves, buds, and flowers. Figs are an important part of their diet. They have rounded wings and long tails and strong legs, making them poor fliers, but good runners.[6]

Turacos are medium-sized arboreal birds endemic to sub-Saharan Africa, where they live in forests, woodland and savanna.

They are gregarious, non-migratory birds which move in family groups of up to 10. Many species are noisy, with the go-away-birds being especially noted for their piercing alarm calls, which alert other fauna to the presence of predators; their common name is onomatopoeia of this. Musophagids build large stick nests in trees, and lay twp or three eggs. The young are born with thick down and open, or nearly-open, eyes.[7]
