Lagopus muta

Rock Ptarmigan has 25 subspecies.

Rock Ptarmigan is mostly active in groups except during the breeding season, mostly in small groups of 3-5, and sometimes even up to 100 in winter. It mainly moves on the ground, and roosts in snow caves at night in winter. It flies quickly, but not far. It lives in groups in autumn and winter, up to hundreds of them. Its call is a rough kuh, kuh, kwa-kwa-kwa, or the male bird calls arr, arr fiercely. Its food mainly consists of birch, willow, and tender branches, buds, tender leaves, flowers, berries, seeds and fruits of various shrubs and herbs.

The breeding season of the rock ptarmigan is from June to August. After arriving at the breeding ground, the male birds first divide the territory, and each of them keeps singing and flying in their own territory. At the same time, the fleshy crown above the eyes swells and the color becomes a brighter blood red. If other male birds invade, they will immediately fly over with their fleshy crowns erected and tail feathers open to drive them away. They are very territorial. When the female bird is attracted to its territory by its courtship call, it will run over with its neck arched, tail feathers cocked, wings half-opened, and head extended toward the female bird to show courtship. The female bird lowers her head, slightly opens her wings, and stretches her body downward. Then the male bird jumps onto the female bird's back and bites the feathers on the back of her neck to mate. Each male bird can mate with 2-3 female birds. After mating, the female bird starts to nest alone, usually in the male bird's territory. The nest is mostly built in the alpine tundra rich in shrubs or near the rocks on the hillside, often hidden by rocks or shrubs. The nest is relatively simple, with 6-13 eggs per nest. The eggs are ochre in color with dense chestnut spots. The incubation period is 24-26 days. After hatching, the chicks move with their parents to the higher, moist and warm hillside areas, and form a larger group.

The real threat to the survival of the rock ptarmigan is all kinds of birds and beasts, because with the skills of the rock ptarmigan, except for escaping, there is no chance of victory. Just like the snowy owl, skuas, etc., they can almost easily deal with the rock ptarmigan. In nature, the rock ptarmigan is basically at the bottom of the food chain like lemmings, and everyone who sees them wants to exploit them.

It can also live in alpine meadows above 2500 meters. It is a bird that lives in the tundra and forest-steppe areas near the Arctic.
