[Port.] An Australian bird related to the cassowary and ostrich, and, next to the ostrich, the largest of birds. It cannot fly, but runs swiftly. The emu kicks backward or sideways, while the ostrich kicks forward. Emu feathers are scarcely distinguishable from ordinary hair. The male bird hatches and broods the young. In its wild state it feeds on parrots or other birds; but it is often made a household pet, though mischievous and cunning. It is the only running bird that wanders in pairs. Its eggs are of a beautiful dark-green color.
