The Greenfinch (or Green Linnet) is a large stocky finch with a distinctly forked tail. It's about the size of a Great Tit.
In summer, the adult male is mostly olive-green except for yellow edges to their outer primary wing feathers and tail feathers, and a more yellow rump. The coverts, cheeks and undertail coverts are greyish. During the winter, the male becomes duller.
The adult female has grey-brown, slightly streaky upperparts, the underparts are tinged with yellow and there is less yellow on the wings and tail than the male.
