Australian Bustard

The Australian bustard is a large ground-dwelling bird that is common in grassland, woodland and open agricultural country across northern Australia and southern New Guinea. It stands at about one metre high, and its wingspan is around twice that length. The species is nomadic, flying to areas when food becomes plentiful, and capable of travelling long distances. They were once widespread and common to the open plains of Australia, but became rare in regions that have been used for farming. The bustard is omnivorous, mostly consuming the fruit or seed of plants, but also eating invertebrates such as crickets, grasshoppers, smaller mammals, birds and reptiles.
