Taxonomy

The Altai snowcock was first described by Frederic Gebler in 1836. He was a doctor and naturalist who lived in the Altai region for forty years and named many previously unknown species. There are two subspecies, ''Tetraogallus altaicus altaicus'' and ''Tetraogallus altaicus orientalis''.

Description

The Altai snowcock is a plump, partridge-like bird. While most snowcocks are similar in size, the Altai might be the largest species with a length of around and a mean body mass of approximately in females and in males. The head and neck are slatey-grey and there is a partial dark collar at the base of the neck. The upperparts are grey with white spots and the tail is black. The chin, breast and belly are white.
