They live in Australia and the neighboring islands of New Guinea and New Britain. The emu is the second largest bird in the world, and can measure up to 6 feet in height. Emus live in the semiarid bush of Australia, and apart from the western seaboard and the southeastern tip of Australia, emus can be found almost everywhere on the continent. Emus eat coarse grasses in the wild, but they also like fruit and grain crops. The Australian army was even used to kill emus in 1932 during an episode called the 'Grain Wars'.
Cassowaries are similar in appearance to the ostriches and emus.
Wattles' are the red and blue folds of skin that hang from the cassowary's neck, and the other main characteristic of these birds is the horny casque on the top of the head. The casque may help the bird clear a path through dense undergrowth. Cassowaries live in rainforest regions, and eat mainly fruit, insects and small vertebrate animals. Cassowaries lay their eggs in a shallow hollow on the leafy rainforest floor. Like the ostrich chicks, the cassowary young leave the nest soon after hatching.
