The "towns, camps, and rookeries," as they have been called, of Penguins have been often described. At the Falkland Islands are assemblies of Penguins, which give a dreary desolation to the place, in the utter absence of the human race. In some of the towns voyagers describe a general stillness, and when the intruders walked among the feathered population to provide themselves with eggs, they were regarded with side-long glances, but they seemed to carry no terror with them. In many places the shores are covered with these birds, and three hundred have been taken within an hour; for they generally make no effort to escape, but stand quietly by whilst their companions are knocked down with sticks, till it comes to their turn. The rookeries are described as designed with the utmost order and regularity, though they are the resort of several different species. A regular camp, often covering three or four acres, is laid out and levelled, and the ground disposed in squares for the nests, as accurately as if a surveyor had been employed. Their marchings and countermarchings are said to remind the observer of the manoeuvres of soldiers on parade. In the midst of this apparent order there appears to be not very good government, for the stronger species steal the eggs of the weaker if they are left unguarded; and the King Penguin is the greatest thief of all. Three species are found in the Falkland Islands. Two, the _Kings_ and the _Macaroni_, deposit their eggs in these rookeries. The _Jackass_, which is the third, obtained its English name from its brayings at night. It makes its nests in burrows on downs and sandy plains; and Forster describes the ground as everywhere so much bored, that a person, in walking, often sinks up to the knees; and if the Penguin chance to be in her hole, she revenges herself on the passenger by fastening on his legs, which she bites very hard. But these rookeries are insignificant when compared with a settlement of King Penguins, which Mr. G. Bennett saw at the north end of Macquarrie Island, in the South Pacific Ocean--a colony of these birds, which covered some thirty or forty acres. Here, during the whole of the day and night, 30,000 or 40,000 Penguins are continually landing, and an equal number going to sea. They are ranged, when on shore, in as regular ranks as a regiment of soldiers, and are classed, the young birds in one situation, the moulting birds in another, the sitting hens in a third, the clean birds in a fourth, &c.; and so strictly do birds in a similar condition congregate, that, should a moulting bird intrude itself among those which are clean, it is immediately ejected from them. The females, if approached during incubation, move away, carrying their eggs with them. At this time the male bird goes to sea, and collects food for the female, which becomes very fat.
