Sound of a Cassowary bird

The cassowary is a large flightless bird found in Papua New Guinea, southern Indonesia and northern Australia. They belong to the group known as ratites, which also includes ostriches, emus, and rheas.The cassowary has a horny helmet called a casque (say cask) , on its head. Some scientists believe that this helps it crash its way through the thick forest. It may also help the booming sound the bird makes echo more loudly through the thick forests where it lives.The skin on the cassowary's head
