Sometimes the bait would attract an Albatross, cause him to alight, and shake it with his beak; but, “putting on a knowing look,” he eyed it again, perhaps suspicious of its appearance, would refuse it, and fly off. Perhaps he had had a good feast of cuttle-fish, and therefore, being in a dainty mood, did not like the bit of skinny pork that was offered for his acceptance. These birds are the greatest part of their existence on the wing; but there are other of the oceanic birds which merely seek their food during the day, returning to the land to roost at night; but, from sometimes being blown away by heavy gales, they are obliged to bear away for the nearest port, and take refuge, much exhausted, on the rigging of ships. The booby is one of these; and from the circumstance of being easily captured at night on the rigging, has received its common name, whereas it is as much gifted with sense as any of the oceanic tribe of birds, which, at the best, is not an overplus; but Nature, no doubt, has given them as much as they require for their existence in this world. So marked is the form of the superorbital depression in aquatic birds, that I have no doubt, judging from my limited series of observations, the genus may be determined by it alone. So marked is it in the Albatross genus, that from it the skull of that bird may be easily recognized. The Petrel tribe have it only half bony, the membranous portion projecting from the outer edge of the bone, which membranous portion is usually found wanting in the prepared skulls of those birds. In the Larus or gull tribe, the flatness of the cavities, and their extending over the anterior part of the skull, so as nearly, if not actually, to touch, seems a distinguishing mark in that genus. In the booby, duck, and some others, there is no depression, although the gland exists, being situated over the orbit, merely on a membranous projection.
