The yellow-thigh hawfinch ( Mycerobas affinis ) is a species from the goldfinch-like subfamily . The species occurs exclusively in Asia. The IUCN classifies the yellow-thigh hawfinch as not endangered ( least concern ).
Appearance
The yellow-thigh grosbeak reaches a body length of 22 to 24 centimeters. The males resemble those of the golden grosbeak , however the black plumage of the yellow-thigh grosbeak is more extensive.
The male of the yellow-thigh hawfinch has a black head. The black extends to the front of the chest. The wings and tail are also black. The rest of the body are bright yellow. The females, on the other hand, are much more inconspicuous in color. Their plumage is almost monochrome olive green. On the underside of the body as well as in the neck, the plumage has a yellowish tinge. The wings and tail are also black in the female. Both sexes have reddish brown eyes.
Way of life
The distribution area of the yellow-thigh hawfinch stretches from northern Pakistan through northern India and Tibet to Yunnan in southwest China . The distribution area overlaps with that of the gold grouse. However, it is significantly larger, especially in China. Like the golden grosbeak, the yellow-thigh grosbeak is also a species of high altitude. It usually occurs at altitudes between 2,500 and 4,000 meters. Its habitat is forests and bushland with a population of pines , spruces , birches , junipers and rhododendrons . During the winter months it stays at lower altitudes and then migrates to Myanmar and northern Thailand .
The nest is cup-shaped. The clutch comprises two to four eggs. The female breeds alone. The incubation period is thirteen to fourteen days. The young birds fledge after 17 to 18 days, which is relatively long for a goldfinch.
