Social behaviour

The house sparrow is a very social bird. It is gregarious during all seasons when feeding, often forming flocks with other species of birds. It roosts communally while breeding nests are usually grouped together in clumps. House sparrows also engage in social activities such as dust or water bathing and "social singing", in which birds call together in bushes. The house sparrow feeds mostly on the ground, but it flocks in trees and bushes. At feeding stations and nests, female house sparrows are dominant despite their smaller size, and they can fight over males in the breeding season.
