"Sent from Connecticut, to Mrs. Blackburn. Possibly the great flocks of pretty Pied Ducks, which whistled as they flew, or as they fed, seen by Mr. Lawson in the western branch of Cape Fear inlet, were of this kind." The Labrador-Duck is one of those birds, the disappearance of which is not easily explained. As Mr. Dutcher truly said, "we can speculate as to the cause of its disappearance, but we have no facts to warrant a conclusion." Formerly _Camptolaimus_ was of regular occurrence along the northern Atlantic shores of North America, in winter south to New Jersey and New York. It has often been sold on the markets of New York and Baltimore, and nobody anticipated even fifty years ago that they might become extinct, but they {106} appear never to have been very numerous, at least we have no proof of this. It is true that Professor Newton tells us that this duck used to breed on rocky islets, and that "its fate is easily understood," since "man began yearly to visit its breeding haunts, and, not content in plundering its nests, mercilessly to shoot the birds." This, however, seems to be mere conjecture, as we do not know for certain where the breeding haunts of this Duck have been, and that anyone has ever visited them. All information known about the breeding of this bird is that of Audubon, who says that his son was shown empty nests on the top of bushes, which a clerk of the fishing establishment told him were those of the Labrador Duck. This information is certainly too uncertain to draw any conclusions from, but the breeding places might just as well have been much further to the north, and probably were.
