Emus are large, flightless birds found throughout Australia, including Arnhem Land. The male emus guard the nest. Females cease contact with the young once the eggs are laid and males incubate the eggs and raise the fledglings until the chicks are independent. The emu is a prized food source for Aboriginal people in western and central Arnhem Land. The exaggerated chest is called a crop and birds use the crop for storing and digesting food. The small appendages under the chest are the feeble wings. To compensate for their lack of flight, emus are very fast runners.
Emus are Yirridjdja moiety, Bulanj or Bulanjdjan skin. They are known as Alwanjdjuk in Gundjeihmi dialect and in stone country people they call emu Ngurrurdu and here we call Kurdukadji..
