Biology

Rare resident. Inhabits the pine and spruce groves, the larch forests with bushes and deciduous trees both on plains and in mountains at altitudes 1450-1900 m. In April - May males display in small groups (3-10 birds). Nest is built by female mostly on southern slopes, under the bush in shallow hole and is lined with thin twigs and grass. Clutch of 6-8 eggs is laid from early-mid May to early June. Only female incubates clutch and care juveniles which hatch from the end of May to early July. In September - October birds join to flocks (separately males and females) and begin to disperse in nearby areas with plenty food, at distance more than 50 km.

The subspecies of birds living in Kalbinskiy Altai is unknown. Capercaillie living in Kokchetav pine forest was introduced in 1912, and then in 1964 and 1986 from the Kirovskaya Province and Novosibirskaya Province.
