The Himalayan finch ( Chloris spinoides , Syn .: Carduelis spinoides ), also called Himalayan greenling , more rarely Himalayan siskin or siskin greenling , is a species from the goldfinch subfamily . The species occurs exclusively in Asia.
Appearance
The Himalayan finch reaches a body length of thirteen centimeters. It is therefore somewhat smaller and slimmer than the greenfinch found in Central Europe . A gender dimorphism is present.
The males of the Himalayan finches have a black skull, black ear patches and a black beard. The forehead is also feathered black up to the neck. The over-eye stripe is bright yellow. The ear patches are also circled in yellow. The chin and throat are also yellow feathered. The back is greenish black. The rump and the upper tail-coverts are yellowish. The elytra and wings are black. However, there are two broad yellow bands running across it. The wings of the hand have a yellow mirror. The underside of the body is brownish yellow. The middle of the abdomen and the underside of the tail are whitish.
The female resembles the male, but is a little more dull in color. The body parts that are black in the male are brown-black to brown in her. Young birds are even paler and have dark stripes.
Distribution area and way of life
The distribution area of the Himalayan finch is the Himalayas from Pakistan via Manipur to the west of Myanmar . The species occurs mainly at altitudes between 1,200 and 4,000 meters above sea level. The Himalayan greenling reaches the tree line during the summer half-year. In the winter months he moves to lower areas. The habitat are light forest areas, forest and roadsides as well as plantations and gardens.
The nest is built at a height of two to five meters above the ground. It only breeds the female. The clutch consists of three to six pale blue eggs with brown to purple spots and scribbles. The incubation period is thirteen to fourteen days. The male parent bird also participates in the rearing. The young are fully fledged after seventeen days and independent after another two to three weeks.
Keeping in human care
The Himalayan finch has a long tradition as an ornamental bird in Europe. It was introduced towards the end of the 19th century. It has been on the market more frequently since the 1960s.
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 Chinese finch ( Chloris sinica )
- the Vietnamese greenfinch ( Chloris monguilloti )
