Cassowaries and emu
These heavily built, flightless birds have coarse plumage, but the head and neck are virtually featherless. The young are longitudinally striped. There are two families.
| Family Casuariidae Cassowaries: 3 species Found in forests from New Guinea to northern Australia, the cassowaries have a large bony crest on the forehead, possibly used to fend off obstructions as they run through the undergrowth, and a spike-like inner toe. The skin of the head and the neck is blue or purple. |

| Family Dromaiidae There is one species: the emu Dromaius novaehollandiae - found on the Australian plains. It has no crest, and the head and neck are feathered except for a blue spot on each side. It has brown and yellow stripes as a chick and deep brown plumage when adult. |
