The great peterel is as large as the common albatross, and is carnivorous. It is frequently called the break-bones, or osprey peterel. They are not at all shy, and, when properly cooked, are palatable food. In flying they sometimes sail very close to the surface of the water, with the wings expanded, without appearing to move them in the least degree, or make any exertion with them whatever. The albatross is one of the largest and fiercest of the South Sea birds. It is of the gull species, and takes its prey on the wing, never coming on land except for the purpose of breeding. Between this bird and the penguin the most singular friendship exists. Their nests are constructed with great uniformity upon a plan concerted between the two species—that of the albatross being placed in the centre of a little square formed by the nests of four penguins. Navigators have agreed in calling an assemblage of such encampments a rookery. These rookeries have been often described, but as my readers may not all have seen these descriptions, and as I shall have occasion hereafter to speak of the penguin and albatross, it will not be amiss to say something here of their mode of building and living. When the season for incubation arrives, the birds assemble in vast numbers, and for some days appear to be deliberating upon the proper course to be pursued. At length they proceed to action. A level piece of ground is selected, of suitable extent, usually comprising three or four acres, and situated as near the sea as possible, being still beyond its reach. The spot is chosen with reference to its evenness of surface, and that is preferred which is the least encumbered with stones. This matter being arranged, the birds proceed, with one accord, and actuated apparently by one mind, to trace out, with mathematical accuracy, either a square or other parallelogram, as may best suit the nature of the ground, and of just sufficient size to accommodate easily all the birds assembled, and no more—in this particular seeming determined upon preventing the access of future stragglers who have not participated in the labor of the encampment. One side of the place thus marked out runs parallel with the water’s edge, and is left open for ingress or egress. Having defined the limits of the rookery, the colony now begin to clear it of every species of rubbish, picking up stone by stone, and carrying them outside of the lines, and close by them, so as to form a wall on the three inland sides. Just within this wall a perfectly level and smooth walk is formed, from six to eight feet wide, and extending around the encampment—thus serving the purpose of a general promenade.
