text: It is known that eastern imperial eagles will also prey upon great bustards (Otis tarda), though the female is possibly taken as she is about as large as a crane or large goose, it is unlikely that the eagle can take the much larger adult males of this huge ground bird, since imperial eagles apparently even avoids adult male birds of much smaller species such as pheasants.
