About These Birds
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.
Lesser Prairie-chicken
A medium-sized grouse (~725 g) of family Phasianidae, paler than Greater Prairie-chicken with crimson-orange air sacs in males. Inhabits arid mixed-grass and shinnery oak prairies in the southern Great Plains of the United States. Feeds on plant matter and invertebrates. Vulnerable; severe population declines due to oil and gas development, overgrazing, drought, and loss of native shrub prairie.
