This species is listed as Data Deficient because it is known from only two specimens, thus there is insufficient information available for assessment of its threat status.

Geographic Range [top]

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.
