About These Birds
Malaysian Crested Argus
A poorly known Phasianidae pheasant of montane forests in peninsular Malaysia. Closely related to the Annamite Crested Argus but considered a separate species; males feature similar spectacularly elongated spotted tail feathers. Solitary and secretive. Diet presumed frugivorous and insectivorous. Near Threatened.
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.
