except during the evening and about daybreak, at the latter time always flying in the direction of the island as if hastening homewards. I have also, when at sea, engaged in cod-fishing to the westward of the Harris Islands, in very gloomy and rainy weather observed a few Fulmars flying about the boat, probably attracted by the fish we had caught. At its breeding-places, however, the Fulmar is always in motion, comparatively few being to be seen upon the rocks, the great mass being engaged flying in circles along the face of the precipice and always in the same direction, none crossing, probably on account of the confusion this would cause among such an immense multitude. I never heard them utter any cry when thus engaged, not even when their nests were being robbed. The Fulmar does not allow itself to be handled with impunity, but defends itself with its powerful bill, which it can use with as much effect as good will.” says the elder Macgillivray, “it is surprising , «Considering the vast number that resort to St. Kilda,’ that so few are to be seen along the west coast of Scotland; on the eastern side, however, where there 1s no breeding-place, individuals often appear in stormy weather in the Moray Frith ; and along the coast from St. George to Fraserburgh many continue all the winter, arriving toward the end of autumn and departing in spring.” From the various statements made by observers it appears that the Fulmar feeds on fishes, cepha- lopodous mollusca, cirripedia, and most other kinds of animal substance, especially such as are oily or fatty. The Rev. Mr. Scoresby, in his ‘ Arctic Regions,’ states that it 1s the constant companion of the whale-fisher, joining his ship immediately on passing the Shetland Islands, and accompanying it to the highest accessible latitudes, keeping an eager watch for any thing thrown overboard. ‘‘ Fulmars are extremely greedy of the fat of the whale. Though few should be seen when a whale is about to be captured, yet, as soon as the flensing process commences they rush in from all quarters, and frequently accumulate to many thousands in number. They then occupy the greasy track of the ship, and, being audaciously greedy, fearlessly advance within a few yards of the men employed in cutting up the whale. If, indeed, the fragments of fat do not float sufficiently away, they approach so near the scene of operations that they are knocked down with boat- hooks in great numbers, and sometimes taken up by the hand. ‘The sea immediately about the ship’s stern is occasionally so completely covered with them that a stone can scarcely be thrown overboard without striking one. When any thing is thus cast among them, those nearest the spot where it falls take the alarm ; and these, exciting fear in others more remote, sometimes put a thousand of them in motion; but as in rising into the air they assist their wings for the first few yards by striking the water with their feet, there is produced by such a number of them a loud and most singular splashing. It is highly amusing to observe the voracity with which they seize the pieces of fat that fall in in their way; the size and number of pieces they take at a meal; the curious chuckling noise which in their anxiety for despatch they always make, and the jealousy with which they view, and the boldness with which they attack, any of their species engaged in devouring the finest morsels. They frequently glut themselves so completely that they are unable to fly ; in which case, when they are not relieved by a quantity being disgorged, they endeavour to get on the nearest piece of ice, where they rest until the advancement of digestion restores their wonted powers. Then, if opportunity permit, they return with the same gust to the banquet as before; and though numbers of the species may be killed, and allowed to float about among them, they appear unconscious of any danger to themselves.” We learn from Mr, Newton’s ‘Notes on the Birds of Spitsbergen”. that Dr. Malmgren found the Falmar breeding in thousands on the north side of Brandywine Bay, lat. 80° 24’ N., and in smaller numbers on the Alkenhorn and also on Bear Island. ‘The very limited number of the breeding-places of the Fulmar,” remarks Mr. Newton, ‘‘ forms a curious contrast to the extraordinary abundance of the species.” A very interesting account of this bird by Capt. Elwes will be found in ‘The Ibis’ for 1869; but as the details are similar to those already given from the pen of John Macgillivray, I have not considered it necessary to make any extracts from it. I have observed a considerable variation in the size of the Fulmars that have come under my notice, particularly in two which bad been captured on the coast of Yorkshire, and were kindly sent me by Mr. J. H. Gurney, Jun. One of these was so much darker than the other in colouring that it might almost be described as of a uniform deep grey, while the other, a large old male, had the upper surface of a light silvery grey and the under surface pure white. The figures represent a bird in the usual plumage, and the dark-coloured specimen above mentioned, both of the natural size.
