These “arries” seem to occupy a ribbon strip in width: it is drawn around the outward edges of the flat table-top to Walrus Island as a regular belt, reserved all to themselves: while the small grassy interior from which they are thus self-excluded is the only place, I believe, in Bering Sea where the big white gull, _Larus glaucus_, breeds. Here I found among grassy tussocks the white burgomaster building a nest of dry grass, sea-ferns, _Sertularidæ_, etc., very nicely laid up and rounded, and in which it laid usually three eggs, sometimes only a couple; occasionally I would look into a nest with four. These heavy gulls could not breed on either of the other islands in this manner, for the glaucous gull is too large to settle on the narrow shelf-ledges of the cliffs, as the smaller gulls do, and lesser water-fowls, and those places which could receive it would also be a happy hunting-ground and footing to the foxes. The red-legged kittiwake, _Rissa brevirostris_, and its cousin, _Rissa tridactyla_, build in the most amicable manner together on the faces of those cliffs, for they are little gulls, and they associate with cormorants, sea-parrots, and tiny auks, all together, and, with the exception of the last, their nests are very easy of access. All birds, especially the “arries,” have an exceedingly happy time of it on this Walrus Islet—nothing to disturb them, in my opinion, free from the ravenous maw of blue foxes over on St. Paul, and from the piratical and death-dealing sweep of owls and hawks, which infest the Aleutian chain and the mainland. The position of the islands is such as to be somewhat outside of that migratory path pursued by the birds on the mainland, and owing to this reason they are only visited by a few stragglers from that quarter, a few from the Asiatic side, and by the millions of their own home-bred and indigenous stock. One of these migratory species, a turnstone, however, comes here every summer, for three or four weeks’ stay, in great numbers, and actually gets so fat in feeding upon the larvæ which abound in the decaying carcasses over the killing-grounds that it usually bursts open when it falls, shot on the wing. A heavy easterly gale once brought a strange bird to the islands from the mainland—a grebe, _P. griseigena_. It was stranded on St. George in 1873, whereupon the natives declared the like of which they had never seen before; again, I found a robin one cool morning in October, the 15th: the natives told me that it was an accident—brought over by some storm or gale of wind that took it up and off from its path across the tundra of Bristol Bay. The next fair wind sweeping from the north or the west could be so improved by this robin, _M. migratoria_, that it would spread its wings and as abruptly return. Thus hawks, owls, and a number of strange water-fowls visit the islands, but never remain there long.
