Ostrich
Definition:
(n.) A large bird of the genus Struthio, of which Struthio camelus of Africa is the best known species. It has long and very strong legs, adapted for rapid running; only two toes; a long neck, nearly bare of feathers; and short wings incapable of flight. The adult male is about eight feet high.
