The Burtongimpel ( Callacanthis burtoni ), also called goldfinch, is a species from the subfamily of goldfinch-like (Carduelinae) and the only recent representative of the genus Callacanthis . The species occurs exclusively in Asian high mountains. The species is currently classified as not endangered ( least concern ) by the IUCN .
Appearance
The burton pennant reaches a body length of seventeen to eighteen centimeters. A sexual dimorphism is given to a small extent. The females are overall a bit more gray-brown. They lack the orange facial drawing.
The male of the burton is colored auburn. The top of the body is a little darker. The head, wings and tail are black. The forehead and the area around the eyes are reddish orange. The tips of the large wing covers and the wings are white. The feet and the beak are brightly horn-colored. The eyes are brown.
Way of life
The distribution area of the burton impulse is the Himalayas from Pakistan to Sikkim . Similar to the snow bullfinch ( Leucosticte ), the burton bullfinch is a bird of high altitude. It occurs during the summer months at altitudes between 2,000 and 3,500 meters. It is a migratory bird that migrates to lower altitudes during the winter months. It can then be found at altitudes above 1,000 meters.
Unlike the snow bull, the burton does not build its nest on the ground, but in conifers at heights between 3 and 21 meters. The nest is very solid and is made of small twigs, blades of grass, pine needles and hair. The clutch consists of three to four eggs. The female breeds alone.
