BUSTARD, a bird (Otis tarda), now extinct in Britain, but inhabiting other parts of Europe, Asia as far east as Mesopotamia, and also Morocco. It lives in open uncultivated country, feeding on plants, worms and small ani mals. It grows to a length of 4 ft., with an expanse of wing of 8 ft., and may weigh 32 lb. A wary bird, its flight is powerful and sustained. The bustard is migra tory in most parts of its range, and is probably polygamous. In courting, the head is bent back so as almost to touch the uplifted tail, the throat-pouch inflated and the white secondary feathers ex posed. (See COURTSHIP OF ANI
