Some time ago I mentioned that there were penguins of weak individuality who allowed others to rob them of their stones, and this was in some cases very noticeable on the flooded ground, and there were one or two nests here which had been almost entirely removed by thieving neighbours.
To quote again from my notes.
“November 10. This evening I saw a hen penguin trying to sit on a nest with two eggs. The nest had no stones, and was scooped deeply in the ground in a slush of melting snow, so that the eggs were nearly covered with water. The poor hen stood in the water and kept trying to squat down on the eggs, but each time she did so, sat in the water and had to get up again. She was shivering with cold and all bedraggled.
“I took the two eggs out of the nest, and Browning and I collected a heap of stones (partly from her richer neighbours!) and built the nest well up above the water. Then I replaced the eggs, and the hen at once gladly sat on them, put them in position, and was busily engaged in arranging the new stones round her when we left.”
One day, when the season was well advanced, I saw a violent altercation taking place between two penguins, one of which was in possession of a nest in a somewhat isolated position. The other evidently was doing his utmost to capture the nest, as whenever he got the other off, he stood on it. There were scarcely any stones in the nest, which contained one egg. I think from the way they fought that both were cocks.
For two reasons I make special mention of the occurrence, first, because of all the fights I ever saw this was the longest and most relentless, and, secondly, because the nest being in such an isolated position it seemed curious that there could be any mistake about its ownership. Such, however, seemed to be the case, and hour after hour, during the whole day, they fought again and again.
After each bout of a few minutes both birds became so exhausted that they sank panting to the ground, evidently suffering from thirst and at the limit of their endurance. Sometimes one captured the nest, sometimes the other, but after several hours of this, one of them began to show signs of outlasting the other, and kept possession. For long after this, however, the other returned repeatedly to the attack.
