The southern cassowary ("Casuarius casuarius"), also known as double-wattled cassowary or two-wattled cassowary, is a large flightless black bird with hard and stiff plumage, two dangling red wattles and a big bony lump on its head called a casque. It lives in tropical rainforest and feeds mostly on fallen fruit, red nape and two red wattles hanging down its throat.
