Australian Bustards are one of the larget birds in Australia, behind the Emu and Southern Cassowary, at 80-120 cm in height. They are birds of grassy plains and open woodland, where they forage for insects, seeds, fruit, lizards, mammals and anything else they can find and catch. The males are larger than the females, who look after the eggs and young. These birds were found across much of Australia in the past, but are now found mainly in the northern half of the country. When mating, the males inflate a neck-sac and make loud noises to attract the females. Bustards are also an important part of Aboriginal culture, providing food (they're apparently quite tasty) and feathers for decoration.
