Tree sparrow Passer montanus

Tree sparrows are scarce birds of farmland, hedgerows and woodland edges and are not associated with man in the way that the house sparrow is in the UK. Male and female tree sparrows look the same, with chestnut-brown crowns, chestnut backs, buff undersides, white cheeks and a black cheek-spot. They can be distinguished from the male house sparrows by the brown cap, instead of grey, and by presence of the black cheek-spot.

Behaviour

Tree sparrows mate for life; they nest in holes in trees and can produce two or three broods a year, each containing up to seven eggs. They eat seeds, weeds, cereals and also insects.
