Behavior

Rock ptarmigans seasonally migrate for short distances, flying south to wintering grounds in winter. They make gender specific flocks in winter which disband at the onset of spring. Males become territorial during spring and defend their area vigorously when an intruder shows up.

Mating & Reproduction

Breeding season occurs in spring. Before egg-laying, hens build a nest on the ground in a shallow depression nearby a large rock.  She lays between 7 and 10 eggs which are then incubated for around 21 days.

Life-cycle

Hatchlings are born covered in feather and can leave the nest soon after hatching, usually a day. The mother takes care of her chicks, although they can feed themselves. They become capable of flying at the age of 10 days and become independent after 10 to 12 weeks of age. They reach sexual maturity when they are about 6 months old.
