Unknown, decreasing.
IUCN Red List Status:
Near Threatened
CITES Listing:
Appendix II
Threat Summary:
Not globally threatened. Apparently fairly common within its relatively undisturbed range; recorded as usually occurring in large flocks. The species was formerly threatened by the loss of breeding habitat; however, this eased in the 1990s, but old-growth trees are still used for housing and firewood.
Range:
E Himalayas and Tibetan Plateau, from Arunachal Pradesh, NE India, and SE Tibet, east in Tsangpo River valley, to SW China in SE Xizang, SW Sichuan and W Yunnan. Isolated group 50km from Simao, Yunnan, S China.
Habitat:
Found in highland forest from 2700-4000m (8856-13,120 ft). Seen in coniferous or mixed Pinus and Quercus forest, also from alpine Rhododendron growth areas. Also reported in cultivated valleys at harvest.
Wild Diet:
Feeds on seeds of Pinus tabulaeformis, catkins of Populus ciliata, pine cones and cultivated fruits and grain.
Ecology and Behaviour:
Gregarious; found in noisy, boisterous flocks of up to several dozen individuals. Rarely seen in pairs or singles.
Clutch and Egg Size:
2 to 4 eggs, 36.0 x 27.5mm (1.4 x 1.1 in)
Breeding Season:
June. Nest is in tree cavity, often Populus ciliata; also seen in sand tunnels, presumably in high riverbanks.
