The house sparrow is an opportunistic bird of towns and cities, parks, gardens and farmland. House sparrows feed on a variety of foods, including buds, grains, nuts and scraps, and will visit birdtables and feeders. They live in colonies and nest in holes or crevices in buildings, among Ivy or other bushes, and in nestboxes; they use a variety of materials to make their nests.
Both parents will incubate the three to five eggs and raise the young. House sparrows are residents in the UK, but may disperse from their breeding grounds to feed on nearby farmland and grassland in winter.
Male house sparrows are streaky brown above and grey below. They have chestnut wings with white wingbars, a black bib and a grey cap. Females and juveniles are a drab brown. Tree sparrows look similar to male house sparrows, but have a brown crown and a black spot on each cheek.
