an Australian bird, related to the ostrich, cassowary and rhea. It is a large bird, sometimes weighing 130 pounds, and so is second only to the ostrich in size. Its feet are three-toed, and its feathers, which are double, are of a dull, sooty brown, those about the neck and head being hair-like in texture. It has small, useless wings, but it can run with great speed and uses this method of escape from enemies on the plains. If cornered, however, it can fight viciously, kicking backward with force sufficient to break a man's leg. The emu is very easily tamed and may be kept out of doors in temperate climates. The flesh of the young is said to be a delicacy.
