The Svalbard rock ptarmigan is the largest terrestrial bird overwintering in Svalbard and is widespread in most of the archipelago. Greatest densities are found in central areas of Spitsbergen where plant production is highest. The Svalbard rock ptarmigan is an endemic sub-species of rock ptarmigan. The male (cock) establishes a territory in March–April, which it protects through creating a diversion and making a burping sound. Males can often be spotted sitting on a rock or high ground guarding its territory. The female (hen) lays the 9-11 eggs within the territory. As soon as the chicks are hatched, they leave the nest and start wandering about. They are capable of flying after 10-12 days, but stay with the hen for another 10-12 weeks.
