snowcock
The snowcocks are a group of bird species in the genus ''Tetraogallus'' of the pheasant family, Phasianidae. They are ground-nesting birds that breed in the mountain ranges of southern Eurasia from the Caucasus to the Himalayas and western China. Some of the species have been introduced into the United States. Snowcocks feed mainly on plant material.
==Characteristics==
Snowcocks are bulky, long-necked, long-bodied partridge-like birds. Males and females are generally similar in appearance but females tend to be slightly smaller and rather duller in colouration than males. They are generally grey with varying amounts of white, black and brown according to species and with distinctive white under tail-coverts. Their plumage is thick with a downy base to the feathers which helps them to withstand severe winter temperatures that may fall to . The colour of juvenile snowcocks is similar to the colour of the females and the young are not fully grown until their second year of life.
Snowcocks are heavy birds and are unable to fly far with flapping flight. Instead they run to a high point, launch themselves into the air and glide, gradually losing altitude. They are to be found on open slopes above the tree line where they feed on leaves, shoots, roots, fruits, berries and insects.〔
