The Ivory Gull is an inhabitant of the Arctic Regions, and is only a rare visitor in lower latitudes. It may be regularly met with at Spitzbergen, as also in the Asiatic part of the Arctic Ocean, and in the northern parts of Greenland, but even Iceland seems too far south for its residence. In Greenland it can hardly be called scarce, seeing that during and after the autumnal storms it sometimes makes its appearance in great numbers. Audubon tells us that it visits the southern parts of Labrador and Newfoundland every winter. A few individuals have been seen on different parts of the British coasts. "Although so delicate in appearance," says Scoresby, "this Gull is almost as rare as the Fulmar Petrel, and as little nice in its food; it is, however, more cautious. It is a constant attendant on the flensing operations of the whale-fishers, when it generally seizes its portion while on the wing." Like all other birds inhabiting extreme northern latitudes, it is easily captured indeed, Holboell states that it may be tempted to come within reach of the hand with a bit of bacon tied to a string. Wherever a walrus has been killed these birds are sure to make their appearance, and so devoid of shyness are they, that by throwing them bits of blubber a man may catch as many of them as he chooses. Numbers of these Gulls are constantly to be seen upon the carcases left by the seal-hunters, or the Polar bears, and they are always present around the holes or rifts in the ice, to which seals generally resort. As relates to the breeding of these birds, the same author tells us that on the 7th of July, at the northern extremity of Murchison's Bay, he saw a great number of them upon the ledges of a perpendicular cliff of limestone in company with a variety of other birds. It was easy to perceive that the females were sitting upon their eggs; these were at the time quite unapproachable, but on the 30th of June he was ably assisted by a party of men, furnished with long ropes, to get at some of the nests, which consisted of a small quantity of grass, spread upon the bare rock, and rudely lined with grass, seaweed, moss, and feathers. * * * * *
