The Schwarzkopf Greenfinch ( Chloris ambigua , Syn. : Carduelis ambigua ), and black-headed greenfinch is a species in the subfamily of the Stieglitz-like . The species occurs exclusively in Asia. Since the 1990s, the black-headed greenfinch has also been sold as an ornamental bird .
Appearance
The black-headed greenfinch reaches a body length of thirteen to fourteen centimeters. There is a gender dimorphism .
The male has a black head. Only the throat is yellow. The rest of the plumage resembles that of the Chinese finch . The female, on the other hand, has gray head plumage and the underside of the body is more yellow than that of the male. The eyes are dark brown. The beak and feet are light flesh-colored. The calls and chants of the Schwarzkopf greenfinch resemble the Chinese greenfinch and the greenfinch native to Central Europe .
Distribution area and way of life
The black-headed greenfinch is found from northern Laos and Vietnam to northern Myanmar as well as eastern Tibet and western and southwestern China . The habitat of the Schwarzkopf greenfinch are coniferous and mixed forests at altitudes above 1,200 meters.
The clutch usually consists of four to five pale blue eggs. These have dark spots and scribbles on the shell. The female breeds alone. The incubation period is thirteen to fourteen days. The male takes part in the rearing of the young. The young birds are fledged at around 17 days of life and independent after another two to three weeks.
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 European greenfinch ( Chloris chloris )
- the Chinese finch ( Chloris sinica )
- the Vietnamese greenfinch ( Chloris monguilloti )
- the Himalayan finch ( Chloris spinoides )
