Overview

Distribution

Range Description

Leucosticte sillemi has been described from two specimens collected in 1929 on a barren plateau at 5,125 m in southern Xinjiang Autonomous Region, China (in an area under Chinese administration but also claimed by India). Its population is unknown, but it is presumably localised and scarce. One of the birds collected was a juvenile with wings not yet fully grown and the collector considered that the birds had either bred close to where they were collected or on the nearby peaks in the Kunlun Shan range.

Sillem's Mountain Finch

The Sillem's Mountain Finch or Tawny-headed Mountain Finch[3] (Leucosticte sillemi) is a species of finch in the Fringillidae family. It is found only in China and was only known from two specimens collected in 1929 from the Aksai Chin area of southern Xinjiang Autonomous Region. In 2012, it was confirmed that the bird had been photographed by a French nature photographer, 1500 km from the original collection location.[4]

The species is named after Jérome Alexander 'Lex' Sillem, a Dutch bird collector who was a member of the expedition that collected the specimens in 1929.[5]
