A widespread Eurasian finch (Carduelis chloris) having green and yellow plumage.
- Any of five distinct species of bird within the genus Carduelis:
- the European greenfinch, a common Old World finch, Carduelis chloris, that is mainly green with yellow in the wings and tail.
- the black-headed greenfinch, Carduelis ambigua
- the Oriental greenfinch, Carduelis sinica
- the Vietnam greenfinch, Carduelis monguilloti
- the yellow-breasted greenfinch, Carduelis spinoides
- Some of these relatives lead almost insensibly to the greenfinch (ut supra) and its allies, others to the goldfinch (ut supra), the redpolls and so on.
- Hybrids are also common, the canary breeding freely with the siskin, goldfinch, citril, greenfinch and linnet.
- The nest is rather rudely constructed, and the eggs, generally four in number, resemble those of the greenfinch, but are larger in size.
