The cassowary inhabits dense tropical forest on New Guinea and it's surrounding islands and parts of north-eastern Australia. There are three species of cassowary which are the Southern Cassowary or Double-wattled Cassowary, found in southern New Guinea, northeastern Australia, and the Aru Islands, the Dwarf Cassowary or Bennett's Cassowary, found in New Guinea, New Britain, and on Yapen, and the Northern Cassowary or Single-wattled Cassowary, found in northern and western New Guinea, and Yapen.
The cassowary is an omnivorous bird and therefore eats a wide variety of both plants and animals in order to gain all the nutrients that it needs to survive. Cassowaries mainly feed on fruits that have fallen to the ground from the trees, along with leaves, grasses, seeds, insects, spiders and other invertebrates.
The cassowary has adapted to a life without the need to fly due to the fact that, historically, the cassowary had no predators within it's natural environment and therefore had no need to flee. However, with human settles can mammalian predators including dogs, foxes and cats that mainly destroy the vulnerable nests of the cassowary, eating their eggs.
The cassowary breeding season is thought to be from May to June when the female cassowary lays up to 8 large, dark eggs into a nest on the ground made from leaf litter. However, the female cassowary then leaves her eggs to be incubated by the male who fiercely guards his future brood from predators for up to 50 days when the cassowary chicks hatch out of their shells.
Today, mainly due to deforestation and therefore habitat loss and the introduction of predators to the cassowary's native islands, all three cassowary species are at risk in the wild and are classified as vulnerable animals.
