СКАЧАТЬ Reinhardt states that it is much more numerous in the northern than in the southern part of Greenland. Sir John Richardson, who, during seven years’ residence in the Arctic regions, enjoyed unusual opportunities for studying the habits of this Owl, says that it hunts its prey in the daytime. It is generally found on the Barren Grounds, but is always so wary as to be approached with difficulty. In the wooded districts it is less cautious.

      Mr. Downes states that this Owl is very abundant in Nova Scotia in winter, and that it is known to breed in the neighboring province of Newfoundland. In some years it appears to traverse the country in large flocks. In the winter of 1861–62, he adds, these birds made their appearance in Canada in large numbers.

      Mr. Boardman states that they are present in winter in the vicinity of Calais, but that they are not common. A pair was noticed in the spring of 1862 as late as the last of May, and, in Mr. Boardman’s opinion, were breeding in that neighborhood. In the western part of Maine Mr. Verrill found it also rather rare, and met with it only in winter. He states that it differs greatly in disposition from the Great Horned Owl, being naturally very gentle, and becoming very readily quite tame in confinement, differing very much in this respect from most large Raptores.

      It makes its appearance in Massachusetts about the middle or last of November, and in some seasons is quite common, though never present in very large numbers. It is bold, but rather wary; coming into thick groves of trees in close proximity to cities, which indeed it frequently enters, but keeping a sharp lookout, and never suffering a near approach. It hunts by daylight, and appears to distinguish objects without difficulty. Its flight is noiseless, graceful, easy, and at times quite rapid. In some seasons it appears to wander over the whole of the United States east of the Rocky Mountains, Dr. Heermann having obtained a specimen of it near San Antonio, Texas, in the winter of 1857.

      It is more abundant, in winter, near the coast, than in the interior, and in the latter keeps in the neighborhood of rivers and streams, watching by the open places for opportunities to catch fish. Mr. Audubon describes it as very expert and cunning in fishing, crouching on the edges of air-holes in the ice, and instantly seizing any fish that may come to the surface. It also feeds on hares, squirrels, rats, and other small animals. It watches the traps set for animals, especially muskrats, and devours them when caught. In the stomach of one Mr. Audubon found the whole of a large house-rat. Its own flesh, Mr. Audubon affirms, is fine and delicate, and furnishes very good eating. It is described as a very silent bird, and Mr. Audubon has never known it to utter a note or to make any sound.

      Richardson states that a few remain in the Arctic regions even in midwinter, but usually in the more sheltered districts, whither it has followed the Ptarmigan, on which it feeds. When seen on the Barren Grounds, it was generally squatting on the earth, and, if disturbed, alighted again after a short flight. In the more wooded districts it is said to be bolder, and is even known to watch the Grouse-shooters, and to share in their spoils, skimming from its perch on a high tree, and carrying off the bird before the sportsman can get near it.

      Mr. MacFarlane writes from Fort Anderson that he did not find this species abundant in that quarter, and that its eggs were unknown to him. Mr. B. R. Ross speaks of this Owl as widely distributed, but not common. He found it a winter resident, and has repeatedly seen it at that season near Fort Resolution, and it has been shot in February at Fort Norman. It is very destructive to the snares set by the Indians, eating the hares and breaking the snares, in which they are sometimes caught. The Indians are said to attract these birds near enough to be shot at, by tying a mouse or a piece of hare’s skin to a line, and letting it drag behind them.

      Mr. Donald Gunn writes that the Snowy Owl is merely a visitor in the districts to the west of Lake Winnepeg, but is a constant inhabitant of the country surrounding Hudson Bay. There they hatch their young, from three to five in number, making their nests in the forks of some tall poplar-tree. They lay their eggs very early in the spring, and have hatched their young before other birds begin to nest. This account of their breeding differs from all other statements I have seen, and, if correct, is probably exceptional.

      Although a bird of great vigilance, seldom permitting the hunter to get within range of shot, and equally careful in keeping at a distance from its foe in its flight, it is, Mr. Gunn states, readily deceived and decoyed within easy range by tying a bundle of dark rags to a piece of stout twine, and letting this drag from the end of the hunter’s snow-shoe. The hungry Owl pounces upon the bait, and the hunter turns and shoots it. These birds are sometimes quite fat, and are much prized for food by the Indians. At times they migrate from the more northern regions to the more inland districts. An instance of this took place in the winter of 1855–56. These birds made their appearance about the Red River Settlement in October, and before the latter end of December became very numerous, especially on the plains, where they were to be seen flying at any time of the day. In March all left that vicinity and disappeared. A few pass the summer near Lake Winnepeg, as occasional birds are seen there in the spring and fall. These migrations are supposed to be caused by unusual snow-falls and the scarcity of the animals on which they feed.

      Mr. Dall found them rather rare in the valley of the Lower Yukon, and he has noticed them occasionally flying over the ice in the winter season.

      Mr. Hutchins, in his manuscript observations on the birds of Hudson Bay Territory, speaking of this Owl as the Wapacuthu, states that it makes its nest in the moss on the dry ground, and lays from five to ten eggs in May. Professor Alfred Newton (Proc. Zoöl. Soc. 1861, p. 395) thinks there can be no doubt he refers to this Owl. Richardson states, as the result of his own inquiries, that it breeds on the ground, which the observations of Mr. Hearne confirm. Professor Lilljeborg (Naumannia, 1854, p. 78) found, June 3, 1843, on the Dovrefjeld, a nest of this species which contained seven eggs. It was placed on a little shelf, on the top of a bare mountain, far from the forest, and easy of access. Professor Nilsson was informed, on good authority, that in East Fiarmark the Snowy Owl is said by the Lapps to lay from eight to ten eggs in a little depression of the bare ground on the high mountains. Mr. John Wolley received similar information, and was told that the old birds sometimes attack persons that approach their nests. The 16th to the 24th of May is said to be the time when they usually breed. I received in 1860 an egg of this Owl from Herr Möschler. It had been taken near Okkak, a missionary station of the Moravians, in Labrador, and collected by the Esquimaux. The accounts given by these collectors confirm the statement that this bird always breeds on the ground in open places, and frequently lays quite a large number of eggs. This specimen measures 2.50 inches in length and 1.88 in breadth. It is oblong-oval in shape, equally rounded at either end, and of a dull soiled white. The egg is much discolored, apparently by its contact with the ground.

      Mr. H. S. Hawkins (Ibis, 1870, p. 298) gives an account of the nest and eggs of this species, derived from a correspondent at one of the Moravian missionary stations on the coast of Labrador. The nest is said to consist of only a few feathers, and to be placed generally on a ledge of rocks where there is a slight hollow, sufficient to prevent the eggs from rolling out, but sometimes on the ground. The usual number of eggs is eight; these are not all laid and brooded at one time, but the first two are often hatched by the time the last is laid, so that you may find in one nest young birds, fresh eggs, and others more or less incubated.

      Herr von Heuglin, in his Notes on the birds of Novaja Zemlia (Ibis, 1872, p. 61), mentions meeting with this Owl in Seal’s Bay, on Matthew’s Strait, in the Sea of Kara, where he found three nests with two young birds covered with down. The nest was formed of a shallow depression in the turf, without any lining. The food of the Snowy Owl, in Novaja Zemlia, during the summer time, consisted exclusively of a species of Myodes, which were very numerous. The down of the young is plain brownish-gray. They were easily tamed, and their comical gestures and vivacity are said to have been very amusing.

      Captain C. F. Hall, the celebrated Arctic voyager, during one of his expeditions found a nest and four eggs of this species on the bare ground. These were packed up in an old moccasin, and sent, without emptying, to the Smithsonian Institution, where, after an interval of several months, they were successfully emptied, СКАЧАТЬ
