Cj Roberts: Goldfinch (Conwy, North Wales) A Goldfinch in the Conwy Valley (Latin name Carduelis carduelis) and of the family (Fringillidae). A highly coloured finch with a bright red face and yellow wing patch. Sociable, often breeding in loose colonies, they have a delightful liquid twittering song and call. Their long fine beaks allow them to extract otherwise inaccessible seeds from thistles and teasels. In winter many UK goldfinches migrate as far south as Spain.
