Fig. 54. A Young Sea-Leopard on Sea-Ice
The sea-leopard has not a reputation for attacking men in boats, and this one may have been actuated by curiosity merely, but in favour of its meaning to attack us were, first, that it came to us straight from the direction of the dead bull we had shot, and secondly, that it seems hardly likely that after bumping against our keel, mere curiosity could have tempted it to come back and try to look over the gunwale! As a rule we had to drift very quietly along when hunting sea-leopards, as the slightest sound frightened them away.
All that we could do to protect our friends was to shoot as many of these sea-leopards as possible but though we may have made some difference, there were always many about.
Some idea of the depredations committed by these animals may be gathered from the fact that in the stomach of one which we shot I found the bodies of eighteen penguins, in various stages of digestion, the beast's intestines being literally stuffed with the feathers remaining from the disintegration of many more. Photographs of these animals are seen in Figs. [52], [53], and [54].
Though the actual presence of a sea-leopard put the Adélies to confusion, causing them to “porpoise” madly away for a few hundred yards, yet once away from the immediate neighbourhood of the arch enemy, they appeared to think no more of him, and behaved as though there were no further need for anxiety, though probably they kept a sharp look-out nevertheless. Evidence goes to show that the sea-leopard is the only living enemy, excepting man, that threatens the life of the adult Adélie penguin.
One day, as I watched some hundreds of Adélies bathing in an open lead, suddenly the back of an enormous killer-whale (Orca gladiator) rose above the surface as it crossed the lead from side to side, appearing from beneath the ice on one side and disappearing beneath it on the other. To my surprise, not the slightest fear was shown by the birds in the water. Had this beast been a sea-leopard, there would have been a stampede, and every bird have leapt from the water on to the sea-ice. On this evidence I formed the opinion that in all probability killer-whales do no harm to Adélie penguins; later I saw it confirmed, when a school of killers shaved close past several floes that were crowded with Adélies, and made not the least attempt to get at them, as they might so easily have done by upsetting the floes. Very probably this is because the agile bird can escape with such ease from the ponderous whale, and fears it no more than a terrier fears a cow, though he thinks twice before coming within reach of its jaws.
