Passage: 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, but this was later disputed. Recent genetic analysis have strongly supported the order ranking of Musophagiformes.Musophagids are medium-sized arboreal birds endemic to sub-Saharan Africa, where they live in forests, woodland and savanna. Their flight is weak, but they run quickly through the tree canopy. They feed mostly on fruits and to a lesser extent on leaves, buds, and flowers, occasionally taking small insects, snails, and slugs.  As their name suggests, turacos enjoy bananas and can become so tame as to be hand-fed. They are also partial to grapes and pawpaw (papaya).
