In another islet, in the Straits of Magellan, Captain Drake’s crew killed more than 3,000 in one day. These facts are not exaggerated. This island, when visited by these navigators, probably had never been pressed previously by a human foot, and the Birds had succeeded each other from generation to generation in incalculable numbers, hitherto free from molestation. The Penguins have no fear of man. Mr. Darwin pleasantly relates an encounter that he had with one of these Birds on the Falkland Islands. “One day,” he says, “having placed myself between a Penguin and the water, I was much amused by the action of the Bird. It was a brave Bird, and, till reaching the sea, it regularly fought and drove me backwards. Nothing less than heavy blows would have stopped him. Every inch gained he kept firmly, standing close before me firm, erect and determined, all the time rolling his head from side to side in a very odd manner.” There are many species of Penguins, the handsomest probably being the Crested Penguin, which is a native of Patagonia, and has a very conspicuous appearance. These Birds are called by sailors, regardless of species, Jackass Penguins, from their habit, when on shore, of throwing their head backwards, and of making a strange loud noise very like the braying of a Donkey. This family all defend themselves vigorously with their beaks when an attempt is made to lay hands on them; and when pursued, they will pretend to retreat, and return immediately, throwing themselves upon their assailant. “At other times they will look at you askance,” says Pernetty, “the head inclined first on one side, then on the other, as if they were mocking you.” They hold themselves upright on their feet, the body erect in a perpendicular line with the head. Navigators passing these islands of the southern seas might suppose that they were densely inhabited, for the loud roaring voices of these Birds produce a noise equal to that of a great crowd. The flesh is most unpalatable, but it is frequently the only resource of ship’s crews who find themselves short of provisions in these inhospitable regions. However, their eggs have the redeeming quality of being excellent. THE AUK. The Auk is a noble Bird, which was once common in our waters, but at this date scarce even in the Arctic seas; it is but little known. In habits and mode of life it strongly resembles the Penguins. THE GREBES. The Grebes have the head small, the neck somewhat elongated, the legs attached to the abdomen, the tail rudimentary, the tarsi compressed, the anterior toes united at their base by a membrane. These Birds live on the sea, but they inhabit fresh water by preference, feeding on small Fishes, Worms, Molluscs, Insects, and the products of aquatic vegetation. While they dive and swim admirably, they also fly with vigorous wing; but they rarely resort to this unless alarmed or when migrating.
