Similar species: females and juveniles can be confused with dunnock, greenfinch or chaffinch. Dunnocks are smaller, with darker, more sombre plumage, and a slender dark bill. They usually stay close to cover, and are never in large flocks. Chaffinches differ in their distinctive double wing-bar and white outer tail. The young of greenfinches are greenish above their shorter tail. In comparison with finches, sparrow flight generally is more direct, almost laboured, and usually low.
