lagopède alpin Drôme

Across the DACH Alps the rock ptarmigan inhabits the open alpine belt above the tree line, typically between around 1,800 and 3,000 metres. It favours dwarf-shrub heaths, dry mountain grasslands, moraines and rocky scree fields with sparse vegetation. As an ice age relict it is tightly bound to cold, harsh elevations; temperatures above roughly 15 degrees are already considered stressful. In summer the bird wears a finely mottled grey-brown camouflage, in winter an almost entirely white plumage with feathered feet that blends seamlessly with the snow.

Rock ptarmigan are resident birds that perform only short altitudinal movements within their territory. They are largely monogamous; the female lays a clutch of several speckled eggs and the precocial chicks follow her shortly after hatching. The diet is purely vegetarian, ranging from buds, shoots and berries to leaves and seeds of alpine plants. When threatened, ptarmigan rely on their excellent crypsis and tend to sit tight until a hunter or dog is almost upon them. In winter they dig roost chambers into the snowpack for insulation.

For hunters, the rock ptarmigan is a classic high-mountain quarry. Where seasons are open at all in the DACH region, it is pursued exclusively by demanding stalking in steep alpine terrain, frequently with a pointing dog. At the same time the species is under serious pressure from climate change, shrinking high-altitude habitat and disturbance from tourism and winter sports; models project substantial habitat losses by mid-century. Restrained harvest matched to the local population, and a willingness to step back in weak years, are part of the ethical baseline. Please always follow the closed and open seasons set by your federal state or canton.
