It has an all chestnut brown "hairstyle" plus a white collar and a distinctive black cheek patch. Unusually for sparrows, the male and female have similar plumage. A shy rural bird in the UK, it is a gregarious urban bird like the House Sparrow in parts of Europe, Asia (native) and Australasia (introduced).

These photos of a pair of Tree Sparrows building their nest in a pipe were also taken by Alexandra Makhnina. The similar plumage of the male and the female, unlike House Sparrows, can be seen.
