The goldfinch breeds across Europe, North Africa, and western and central Asia, in open, partially wooded lowlands. It is resident in the milder west of its range, but migrates from colder regions. It will also make local movements, even in the west, to escape bad weather. It has been introduced to many areas of the world.
The average Goldfinch is 1213 cm long with a wingspan of 2125 cm and a weight of 14 to 19 grams. The sexes are broadly similar, with a red face, black and white head, warm brown upperparts, white underparts with buff flanks and breast patches, and black and yellow wings. On closer inspection male Goldfinches can often be distinguished by a larger, darker red mask that extends just behind the eye. In females, the red face does not reach the eye. The ivory-coloured bill is long and pointed, and the tail is forked. Goldfinches in breeding condition have a white bill, with a greyish or blackish mark at the tip for the rest of the year. Juveniles have a plain head and a greyer back but are unmistakable due to the yellow wing stripe. Birds in central Asia (caniceps group) have a plain grey head behind the red face, lacking the black and white head pattern of European and western Asian birds.
The goldfinch's preferred food is small seeds such as those from thistles (the Latin name is from Carduus, a genus of thistles) and teasels, but insects are also taken when feeding young. It also regularly visits bird feeders in winter. They nest in the outer twigs of tall leafy trees, or even in bamboo, laying four to six eggs which hatch in 1114 days.
In the winter goldfinches group together to form flocks of up to forty birds, occasionally more.
The call is a melodic tickeLIT, and the song is a pleasant tinkling medley of trills and twitters, but always including the trisyllabic call phrase or a teLLIT-teLLIT-teLLIT.
