We have already remarked that there are but two species of the true Auk. The Puffin belongs to the sub-genus Fratercula. Of the singular figure of this bird our engraving gives a true representation; of its habits, Selby gives the following account, which is corroborated by other writers who have described it. “Although the Puffin is found in very high latitudes, and its distribution through the Arctic Circle is extensive, it is only known to us as a summer visitant, and that from the south, making its first appearance in the vicinity of its breeding stations, about the middle of April, and regularly departing between the 10th and the 20th of August. Many resort to the islands, selecting such as are covered with a stratum of vegetable mould; and here they dig their own burrows, from there not being any rabbits to dispossess upon the particular islets they frequent. They commence this operation about the first week in May, and the hole is generally excavated to the depth of three feet, often in a curving direction, and occasionally with two entrances. When engaged in digging, which is principally performed by the males, they are sometimes so intent on their work as to admit of being taken by hand, and the same may also be done during incubation. At this period I have frequently obtained specimens, by thrusting my arm into the burrow, though at the risk of receiving a severe bite from the powerful and sharp edged bill of the old bird. At the farther end of this hole the single egg is deposited, which in size nearly equals that of a pullet, and, as Pennant observes, varies in form; in some instances one end being acute, and in others equally obtuse. Its color when first laid is white, but it becomes soiled and dirty from its immediate contact with the earth: no materials being collected for a nest at the end of the burrow. The young are hatched after a month’s incubation, and are then covered with a long blackish down above, which gradually gives place to the feathered plumage, so that at the end of a month or five weeks they are able to quit the burrow, and follow their parents to the open sea. Soon after this time, or about the second week in August, the whole leave our coasts, commencing their equatorial migration. At an early age the bill of this bird is small and narrow, scarcely exceeding that of the young Razor-bill at the same period of life; and not till after the second year does this member acquire its full development, both as to depth, color, and its transverse furrows. “In rocky places, they deposit their single egg in the holes and crevices. The length of the bird is about twelve inches. The half of the bill nearest the head is bluish; the rest red. The corners of the mouth are puckered into a kind of star. The legs and feet are orange. The plumage is black and white, with the exception of the cheeks and chin, which are sometimes gray. The young, pickled with spices, are sometimes considered dainties.” [Illustration]
