ratite, any bird whose sternum (breastbone) is smooth, or raftlike, because it lacks a keel to which flight muscles could be anchored. All species of ratites are thus unable to fly. They are a peculiar and puzzling group, with anatomic anomalies. The group includes some of the largest birds of all time, such as the moa and the elephant bird (Aepyornis). Extant ratites include the ostrich, emu, cassowary, rhea, and kiwi.
