Goldfinch [Carduelis carduelis]

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. Increasingly they are visiting birdtables and feeders. In winter many UK goldfinches migrate as far south as Spain.

Black-winged Stilt [Himantopus himantopus ]

Adults are 33–36 cm long. They have long pink legs, a long thin black bill and are blackish above and white below, with a white head and neck with a varying amount of black. Males have a black back, often with greenish gloss. Females' backs have a brown hue, contrasting with the black remiges. In the populations that have the top of the head normally white at least in winter, females tend to have less black on head and neck all year round, while males often have much black, particularly in summer. This difference is not clear-cut, however, and males usually get all-white heads in winter.
Immature birds are grey instead of black and have a markedly sandy hue on the wings, with light feather fringes appearing as a whitish line in flight.
