The tree sparrow has not penetrated more natural habitats in Australia as the house sparrow has. Diet 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. In Western Australia, sparrows are often detected when they forage for bird seed at aviaries. Breeding Tree sparrows lay buff-coloured spotted eggs between September and January.
House sparrows lay white eggs, spotted and freckled with grey and pale brown.
They breed in spring and summer and at other times if conditions are favourable. The nests are untidy domes made from plant stems, grass, wool and feathers. Nests are placed in tree holes, between the trunks and fronds of tall palms, in haystacks, woodpiles or less frequently in crevices and holes in buildings. Behaviour Sparrows are sociable birds, usually found in small to enormous flocks. Both species are attached to their nest sites for much of the year.
