Casuariidae Casuariidae The bird family Casuariidae has four surviving members: the three species of cassowary and the emu. All living members of the family are very large flightless birds native to Australia-New Guinea, though the extinct potential member "Hypselornis" was native to India. The characteristics of the family are those of its members. The fossil record of casuariforms is interesting, but not very extensive. Some Australian fossils initially believed to be from emus were recognized to represent a distinct genus, "Emuarius", which had a cassowary-like skull and femur and an emu-like lower leg and foot. A Pliocene Indian ratite, "Hypselornis", has
Emu-wren Emu-wren The emu-wrens ("Stipiturus") are a genus of passerine birds in the Australasian wren family, Maluridae. They are found only in Australia, where they inhabit scrub, heathland and grassland. They are small birds, 12–19 cm long with the tail accounting for over half of their length. The tail has only six feathers which are loose and coarse in structure, rather like the feathers of the emu. Three species are recognised, one of which is endangered. The common name of the genus is derived from the resemblance of their tails to the feathers of an emu. The genus was defined by
