The Greenfinch (Carduelis chloris) male is mostly olive-green except for yellow edges to its outer primary wing feathers and tail feathers, and a more yellow rump with a distinctly forked tail. The female has grey-brown, slightly streaky upperparts, the underparts are tinged with yellow. The bills and legs of both sexes are flesh-coloured. Greenfinches nest in colonies in dense shrubs. The nest is made from twigs and grass, and lined with fine roots and hair, and built by the female. The Greenfinch is an abundant British breeding resident with around a million pairs. In winter numbers increase as migrants come to the UK from Continental Europe to escape their cold winters, migrants start to arrive in October to winter in our less severe climate.
