On Spitzbergen there is sometimes to be met with in the interior of the country, on the mountain slopes, a game bird, _spetsbergsripan_, the rock ptarmigan (_Lagopus hyperboreus_, Sund.). A nearly allied type occurs on the Taimur peninsula, and along the whole north coast of Asia. It perhaps therefore can scarcely be doubted that it is also to be found on Novaya Zemlya, though we have not hitherto seen it there. On Spitzbergen this bird had only been found before 1872 in single specimens, but in that year, to our glad surprise, we discovered an actual ptarmigan-fell in the neighbourhood of our winter colony, immediately south of the 80th degree of latitude. It formed the haunt of probably a thousand birds; at least a couple of hundred were shot there in the course of the winter. They probably breed there under stones in summer, and creeping in among the stones pass the winter there, at certain seasons doubtless in a kind of torpid state. [Illustration: PTARMIGAN FELL. Mussel Bay on Spitzbergen, after a photograph taken by A. Envall on the 21st June, 1872. ] The mode of life of the Spitzbergen ptarmigan is thus widely different from that of the Scandinavian ptarmigan, and its flesh also tastes differently. For the bird is exceedingly fat, and its flesh, as regards flavour, is intermediate between black-cock and fat goose.[65] We may infer from this that it is a great delicacy. [Illustration: THE SNOWY OWL. Swedish, Fjelluggla (Strix nyctea L.) ] When I was returning, in the autumn of 1872, from an excursion of some length along the shore of Wijde Bay, I fell in with one of our sportsmen, who had in his hand a white bird marked with black spots, which he showed me as a "very large ptarmigan." In doing so, however, he fell into a great ornithological mistake, for it was not a ptarmigan at all, but another kind of bird, similarly marked in winter, namely, _fjellugglan_, the walrus-hunter's _isoern_, the snowy owl (_Strix nyctea_, L.). It evidently breeds and winters at the ptarmigan-fell, which it appears to consider as its own poultry-yard. In fact, the marking of this bird of prey is so similar to that of its victim that the latter can scarcely perhaps know how to take care of itself. On Spitzbergen the snowy owl is very rare; but on Novaya Zemlya and the North coast of Asia--where the lemming, which is wanting on Spitzbergen, occurs in great crowds--it is common. It commonly sits immoveable on an open mountain slope, visible at a great distance, from the strong contrast of its white colour with the greyish-green ground. Even, in the brightest sunshine, unlike other owls, it sees exceedingly well. It is very shy, and therefore difficult to shoot. The snow ptarmigan and the snowy owl are the only birds of which we know with certainty that they winter on Spitzbergen, and both are, according to Hedenstroem, native to the New Siberian Islands (_Otrywki o Sibiri_, p. 112).
