The China finch ( Chloris sinica , Syn .: Carduelis sinica ), also China greenling , is a species from the goldfinch subfamily . The species occurs exclusively in Asia . It is one of the finch birds that are occasionally kept as an ornamental bird .
Appearance
The Chinese finch reaches a body length of 14 centimeters. In its appearance it is reminiscent of the greenfinch that is widespread in Central Europe . However, this species is brown on the back, the wing covers, the chest and the flanks. The head is gray. The forehead and cheeks are yellowish green. The rump is yellow-green. The wings have a wide yellow band and white ends. A gender dimorphism is present. The females are generally a little duller in color, have a brown head and rump and are sand-colored on the underside. The under tail-coverts are whitish with them.
The song and the calls are reminiscent of both the Himalayan finches and the green finches native to Central Europe.
Distribution and way of life
The distribution area of the Chinese finch stretches from southeast Siberia , Kamchatka , the Kuril Islands , Sakhalin , through the People's Republic of China to Japan and Korea . The Chinese finch lives in forest edges, field margins, banks and light forests and is also found in parks and gardens. The Chinese finches occurring in the northern range are migratory birds. Those in the southern part of the distribution area are line birds , which come together to form larger flocks outside of the breeding season. They are then often associated with other songbird species. The way of life is similar to that of the European green finch and the Himalayan finch.
Systematics
For a long time, the greenfinches were classified in the genus Carduelis . However, based on phylogenetic studies from 2012, this taxon was divided into a larger number of genera. Since then, the greenfinch and its closely related greenling species have been listed in the genus Chloris .
The closely related species of the genus Chloris are:
- the black-headed greenfinch ( Chloris ambigua )
- the European greenfinch ( Chloris chloris )
- the Vietnamese greenfinch ( Chloris monguilloti )
- the Himalayan finch ( Chloris spinoides )
