Bestimmung

The average European 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.<p>On closer inspection, male European 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 female. 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.<p>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.

Taxonomie

The European goldfinch was one of the birds described and illustrated by Swiss naturalist Conrad Gessner in his Historiae animalium of 1555. The first formal description was by Carl Linnaeus in the 10th edition of his Systema Naturae published in 1758. He introduced the binomial name, Fringilla carduelis. Carduelis is the Latin word for 'goldfinch'. The European goldfinch is now placed in the genus Carduelis that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 by tautonomy based on Linnaeus's specific epithet. Modern molecular genetic studies have shown that the European goldfinch is closely related to the citril finch (Carduelis citrinella) and the Corsican finch (Carduelis corsicana).<p>The English word 'goldfinch' was used in the second half of the 14th century by Geoffrey Chaucer in his unfinished The Cook's Tale: "Gaillard he was as goldfynch in the shawe (Gaily dressed he was as is a goldfinch in the woods)".<p>The subspecies of the European goldfinch are divided into two major groups. These intergrade at their boundary, so the groups are not recognized as distinct species despite their readily distinguishable plumage. Subspecies in the carduelis (black-crowned) group occupy the western part of the range and have black crowns; subspecies in the caniceps (grey-headed) group occupy the eastern part of the range and have grey heads.

Verbreitung und Lebensraum

The European goldfinch is native to Europe, North Africa, and western and central Asia. It is found in open, partially wooded lowlands and is a 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.It was introduced to Bermuda, Canada, the United States, Mexico, Peru, Argentina, Chile, the Falkland Islands, Uruguay, Brazil, South Africa, Australia, and New Zealand in the 19th century, and their populations quickly increased and their range expanded greatly. In Australia, they now occur from Brisbane to the Eyre Peninsula, and are also spread throughout New Zealand. In the United States, they have become established in the western Great Lakes region.

Verhalten

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 metres 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.<p>The European goldfinch's preferred food is small seeds such as those from thistles (the Latin name is from Carduus, a genus of thistles), cornflowers, and teasels, but insects are also taken when feeding young. It also regularly visits bird feeders in winter. In the winter, European goldfinches group together to form flocks of up to 40, occasionally more. European 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 European goldfinches feed are sometimes used.
