About These Birds
Taiwan Partridge
A medium-sized partridge (~260 g) of family Phasianidae, with reddish-orange throat, dark brown upperparts, and scaly underparts. Endemic to the montane forests of Taiwan at 500–2,800 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; Taiwan's mountain forests are well protected, supporting stable populations of this island endemic.
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.
