The European goldfinch or simply goldfinch (Carduelis carduelis), is a small passerine bird in the finch family that is native to Europe, North Africa and western Asia. It has been introduced to other areas including Australia, New Zealand and Uruguay.
The breeding male has a red face and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face.
The goldfinch is often depicted in Italian renaissance paintings of the Madonna and Child.
The average goldfinch is 12–13 cm (4.7–5.1 in) long with a wingspan of 21–25 cm (8.3–9.8 in) and a weight of 14 to 19 g (0.49 to 0.67 oz). The sexes are broadly similar, with a red face, black and white head, warm brown upper parts, 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. The shoulder feathers are black, whereas they are brown on the hen. In females, the red face does not extend past 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 (the caniceps group) have a plain grey head behind the red face, lacking the black and white head pattern of European and western Asian birds. Adults moult after the breeding season, with some individuals beginning in July and others not completing their moult until November. After moult birds appear less colourful, until the tips of the newly grown feathers wear away.
The song is a pleasant silvery twittering. The call is a melodic tickeLIT, and the song is a pleasant tinkling medley of trills and twitters, but always including the tri-syllabic call phrase or a teLLIT-teLLIT-teLLIT.
The nest is built entirely by the female and is generally completed within a week. The male accompanies the female, but does not contribute. The nest is neat and compact and is generally located several meters above the ground, hidden by leaves in the twigs at the end of a swaying branch. It is constructed of mosses and lichens and lined with plant down such as that from thistles. It is attached to the twigs of the tree with spider silk. A deep cup prevents the loss of eggs in windy weather. Beginning within a couple of days after the completion of the nest, the eggs are laid in early morning at daily intervals. The clutch is typically 4-6 eggs, which are whitish with reddish-brown speckles. They have a smooth surface and are slightly glossy. The average size is 17.3 mm × 13.0 mm (0.68 in × 0.51 in) with a calculated weight of 1.53 g (0.054 oz). The eggs are incubated for 11–13 days by the female, who is fed by the male. The chicks are fed by both parents. Initially they receive a mixture of seeds and insects, but as they grow the proportion of insect material decreases. For the first 7–9 days the young are brooded by the female. The nestlings fledge 13–18 days after hatching. The young birds are fed by both parents for a further 7–9 days. The parents typically raise two broods each year and occasionally three.
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. In the winter goldfinches group together to form flocks of up to 40, occasionally more. Goldfinches are attracted to back gardens in Europe and North America by birdfeeders containing niger (commercially described as nyjer) seed. This seed of an annual from Africa is small, and high in oils. Special polycarbonate feeders with small oval slits at which the goldfinches feed are sometimes used.
