The Southern Cassowary is a large, distinctive flightless rainforest bird, with black, hairlike feathers, large powerful feet and legs, a colourful neck and a helmet-like structure called a casque atop its head. Its scientific name (species binomial) is Casuarius casuarius johnsonii. Cassowaries are members of the ratite family, like their closest relative the emu. Ratites are flightless, mostly large-bodied birds that are found on the southern continents of Australia and New Zealand, Africa and South America. Other ratites include the African ostrich and kiwis of New Zealand.
