The European Goldfinch or Goldfinch (Carduelis carduelis), is a small passerine bird in the finch family. The average Goldfinch is 12–13 cm long with a wingspan of 21–25 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 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 at numerous places in south-eastern Australia in the 19th century, and their populations quickly increased and their range expanded greatly. They now occur from Brisbane to the Eyre Peninsula. Wikipedia
