House sparrows are exotic birds found in eastern Australia. The birds are prohibited in Western Australia where they are not yet established in the wild.
Sparrows hop along the ground or search in foliage for seeds, soft fruits, flower and leaf buds and grains. They also take flying insects and eat human food scraps.
Sparrows are sociable birds, usually found in small to enormous flocks. They are attached to their nest sites for much of the year. However some individuals disperse hundreds of kilometres to explore sites for new colonies.
