About 15 centimetres long, the chaffinch is easily recognised by its double white wing bar, white tail sides and grey-green rump. The male has rusty-red head sides and breast, and a blue-grey crown and nape. The female is grey-green above with a faint brown tinge, and greyish white below.
The chaffinch can be found in all types of woodland, as well as in parks and gardens. It is widespread throughout Europe and does not migrate in winter.
The chaffinch builds neat nests in tree forks, camouflaged on the outside with lichens and moss. It feeds on insects, seeds and grain.
