Seeds and fruits are the favorite food in the tundra formations. It is not particularly skilled in flight, which is characterized by rigid and frequent flapping of wings, often with inclinations on one or the other side.
Couples are formed in winter, or during the migration season. The nest is placed dry on the ground, well hidden in the undergrowth or among the rocks, however in the vicinity of a stream. It consists of a small concave area and is surrounded by plant material and large quantities of feathers and fluff which the female adds to it after laying about 5 or 6 eggs. After a short time after hatching, which takes place after a month, the chicks leave the nest, as they are already capable of swimming and diving, despite the fact that the mother still provides them for a long time. The first flight takes place about a week after hatching.
