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.
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, and New Zealand, in the 19th century, and their populations quickly increased and their range expanded greatly. They now occur from Brisbane to the Eyre Peninsula in Australia, and throughout New Zealand. source
