Duperrey ("Voyage de la Coquille,") found the Falklands swarming with penguins. In summer and autumn these strange birds leave their burrows early in the morning, and launch into the sea for fishing. After having filled their capacious stomachs, they waddle on shore, and remain for a time congregated on the strand, raising a dreadful clamour; after which they retire to enjoy a noon-tide sleep among the high tussack grass or in their burrows. In the afternoon the fishing recommences. Lesson says that about sunset on fine summer evenings, which unfortunately are but of rare occurrence on those foggy, storm-visited islands, all the penguins together raise their discordant voices, so that at a distance the noise might be mistaken for the hoarse murmur of a great popular assembly. As soon as the young are sufficiently strong, the whole band leaves the island, departing no one knows whither, though the mariners frequenting those seas believe that they spend the winter on the ocean. This opinion seems to be corroborated by the observations of Sir James Ross, who, on the 4th of December, in 49° S. lat., met on the high sea a troop of penguins that were doubtless on the way to their breeding place. He admired the astonishing instinct of these creatures, half fish, half bird, which leads them hundreds of miles through the pathless ocean to their accustomed summer abodes. It may be imagined how the neighbouring seas must abound with fish, to be able to nourish such multitudes of penguins, whose stomach is capable of holding more than two pounds, and whose voracity is so great that they are often obliged to disgorge their superabundant meal. The elongated stomach reaches to the lower part of the abdomen, and the whole length of the intestinal canal is twenty-five feet, fifteen times longer than the body, so that nature has evidently provided for a most vigorous appetite, whetted by sea-bathing and sea air. There are several species of penguins. The largest (_Aptenodytes antarctica_) weighs about eighty pounds. It is a rare bird, generally found singly, while the smaller species always associate in vast numbers. In 77° S. lat., Sir James Ross caught three of these giant penguins, the smallest of which weighed fifty-seven pounds. In the stomach of one of them he found ten pounds of quartz, granite, and trap fragments, swallowed most likely to promote digestion. The penguin, like his northern representative the auk, lays but one single egg. His not unsavoury flesh is black. Besides his dense plumage, he is protected against the cold of the higher latitudes by a thick cover of fat under his skin.
