The Roborowskigimpel ( Carpodacus roborowskii , Syn . : Kozlowia roborowskii ) is a songbird from the finch family . The large, long-winged carmine fin species differs significantly from other representatives of the genus and is therefore often placed in the monotypical genus Kozlowia . It is endemic to rock deserts and mountains of Tibet .
description
Appearance
With a body length of 17-18 cm, the Roborovsky pimple is about the same size as a grosbeak and can be easily distinguished from other species of the genus due to its habitus with the long hand-wing projection. The 12 mm long beak is slender and pointed, strong to pale yellow with a dark tip. The wing length is 121–123 mm, the tail length 90 mm.
The sexes differ significantly in the color of the plumage. The male has a velvety wine-red head, the plumage of which is interspersed with lighter tips and which is gray on the neck, where dark red feathers show up. The back and shoulder feathers are pale gray with pale pink or reddish tips, often forming a stripe or linear pattern. The rump and upper tail-coverts are light pink. The underside is bright pink to pale lilac from the breast down, tinged orange-red on the lower flanks and becoming lighter towards the whitish under tail-coverts. The arm covers are pale brown with light pink hems in the fresh plumage. The wing, coverts and wings are dark brown. The hand wings and outer arm wings are pink, the inner arm wings and umbrella feathers are lined with whitish. The slightly forked tail is black-brown with dark pink edges.
The head of the female is beige-brown with fine dashes. The chin, throat and chest are warmer beige-brown and also darkened. The belly, the flanks and the under tail-coverts are beige and irregularly dashed. Dark feather centers form a stripe on the warm brown back. The rump and tail-coverts are not drawn. The wing feathers and tail are dark brown with beige edges.
The youth dress has not yet been described, but probably resembles that of the female.
The flight is fast and elegant and is reminiscent of the Grandala ( Grandala coelicolor ). The species waddles awkwardly on the ground due to its short legs.
voice
The Roborowskigimpel is not very shouting, but a plaintive, melodic whistle can be heard from time to time, which is often repeated as a short trill.
Distribution and existence
The monotypical Roborovsky pimp occurs in northeastern Tibet, the eastern foothills of the Buckhan Boda Shan , the southern chain of the Amnye Make Mountains and in the Marco Polo Mountains in central Qinghai . The species is rare and little known. According to the IUCN, it is not threatened.
Way of life
The Roborowskigimpel can be found at altitudes between 4500 and 5400 m above sea level and in winter also in somewhat lower elevations. It inhabits rocky deserts and bare plateaus on clay slate mountains - a habitat that is otherwise inhabited by no other species except for the matted snow bull . He can be found individually or in pairs, occasionally also in small family groups. It feeds mainly on seeds and other plant parts that the sparse vegetation offers it.
Systematics
The taxonomic status of this species has long been unclear. The species was described in 1887 as Leucosticte roborowskii and until recently was also often placed in a monotypical genus Kozlowia, which is related to the genus of the snow bullfinch ( Leucosticte ) . A relationship with the genus of the snow sparrows ( Montifringilla ) or the family of the bunting (Emberizidae) has also been suggested. Recent phylogenetic studies from 2012 show that the species, together with its sister species , the sillemfinch ( Carpodacus sillemi ), belong to the genus of the carmine finch ( Carpodacus ).
