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. Unlike the other large flightless birds, cassowary females may mate with more than one male, laying a clutch of eggs for each mate. Kiwis Kiwis are long-beaked, small flightless birds that are only found on the island of New Zealand. They are the remaining members of the order Apterygiformes.
