The southern cassowary is native to Oceania, it lives in the heart of tropical jungles. Its black plumage is made up of coarse feathers, some of them ending in strands like hair, which protect it from the branches and from the humidity. The neck is blue and red in colour and it has a large bony protuberance on the head, called a casque, which can provide the bird with protection when it moves amongst dense vegetation. Since they cannot fly, they feed on fruit that has fallen from trees, well as small insects and fungi.
The southern cassowary is a solitary bird, though it pairs off during the breeding season. During this time, the males produce a low, resonating noise to attract the females. In this species, it is the male who broods the eggs (large, granular and green) and cares for the chicks. The lack of diphormism makes it difficult to distinguish between the sexes.
The greatest threat to this species is the destruction of their habitat.
