About These Birds
Sumatran Partridge
A medium-sized partridge (~335 g) of family Phasianidae, with brownish plumage and scaly underparts. Endemic to Sumatra, inhabiting primary and secondary highland forests at 600–2,000 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; Sumatra's mountain forests retain substantial cover in protected areas, supporting stable partridge populations.
Altai Snowcock
The largest snowcock (~2.77 kg), family Phasianidae, of alpine scree and subalpine meadows in the Altai and Tian Shan ranges of Central Asia. Heavily built, grey and white with rusty-brown markings. Feeds on roots, bulbs, and alpine plants. Forms small flocks outside breeding season. Least Concern.
