About the size of a House Sparrow, the main feature of both female and male Chaffinches is their double white wing bars. Male Chaffinches are striking birds throughout the year, though their plumage is brighter in the summer than in the winter. They have a grey-blue crown and nape, a chestnut back, an olive-green rump and pink-buff cheeks, throat and chest. Females and young birds, on the other hand, are duller. They have an olive-brown back and grey-brown underparts. The female also has a greenish rump.
Makes open-cup nest in shrubs.
