Obs. As stated in the preceding pages, this bird much resembles, if it is not identical with, the species known as _Bernicla Hutchinsii_, from which the most essential distinctive character is the white ring around the neck. If identical, we have, at any rate, the gratification of being the first to represent that species, in mature plumage. At present we regard it as a distinct, though nearly allied bird. The date of the publication of Prof. Brandt’s first description we have not succeeded in ascertaining, not having access to the Bulletin of the Academy of St. Petersburg. The reference to the volume and page we copy from his own citation, in his work above quoted, in which, however, the date is not stated. THALASSIDROMA FURCATA.—(Gmelin.) The Gray Storm Petrel. PLATE XLVI. Adults. The little birds of the group to which that now before the reader belongs, are known to seamen, wherever the English language is spoken, as Storm Petrels, or “Mother Carey’s Chickens,” and have too, a reputation, not without a tinge of superstition, of being the harbingers of the storm and of maritime disaster. Of the many birds adapted by their organization to a life of adventure on the ocean or its tributaries, and of which in fact during a large portion of their lives they are almost as much inhabitants as fishes, the Albatrosses and the Storm Petrels, or Mother Carey’s Chickens, venture the most boldly. The birds of both these genera, though one contains the largest and the other the smallest of marine birds, are alike in this particular character, and are also alike known as inhabitants of shores very remote from each other, and as wanderers over immense extents of the ocean. Boldly directing their course far out on the sea, like their gigantic relatives the Albatrosses, our present little birds are frequently to be met with in nearly all latitudes usually traversed by navigators, and are generally tempted to remain for a time in the wakes of vessels, and about them, by the fragments of food to be gleaned from refuse thrown overboard. Flitting as it were before the gale, with it, the appearance of these birds may readily be coincident, or premonitory of its coming, thus acquiring, and perhaps in some degree justly, the attributed character of precursors.
