About

The tree sparrow is a scarce bird of farmland, hedgerows and woodland edges, and is not associated with man in the way that the house sparrow is in the UK. 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.

What to look for

Male and female tree sparrows look the same, with chestnut-brown crowns, chestnut backs, buff undersides, white cheeks and black cheek-spots. Male house sparrows, however, have grey caps and plain grey cheeks without spots.

Where to find

Widespread in England, southern Scotland and parts of Northern Ireland.
