The skua was disgusted. Had he been what he in some ways so much resembled, namely, a goshawk or falcon, with a hawk’s deadly talons, the encounter would have had a very different result. But his handsome black feet were armed with nothing more formidable than webs for swimming. His only weapons were his hook-tipped beak and his long, powerful, buffeting wings. Backed, however, by his pluck and his audacity, which were worthy of a better occupation, these weapons were usually sufficient, and he was not used to being balked as these two serious little householders had balked him. With a vicious yelp, he went swooping low along the sentinel ranks of the puffins, followed by a snapping of indignant beaks which crackled along the lines as he went – a curious, dry sound, audible through the deep roar of the surf and the high-pitched clamor of bird-cries. Here and there a buffet of his wing, as it dipped suddenly, would knock over one of the grotesque but dauntless doorkeepers, who would pick himself up, ruffle his feathers, and waddle back to his post with outraged solemnity.

But revenge for his recent discomfiture was not the only or the chief reason for this raid of the pirate skua over the domain of the citizen puffins. What he wanted above all was food – whether fish, or eggs, or nestlings, it was all the same to him. A fairly competent fisherman himself – though not, of course, in the same class with the puffins, because of their power of swimming under water – he nevertheless preferred to make others do his fishing for him, and to take toll of their honest gains by force. A hardy and fearless highwayman, there was satisfaction for him in the robbery itself. As he flew thus close, and with the air of set purpose, above the puffin burrows, a few desultory saddle-backs who were circling just above dipped lower to see what was going to happen. In case of a scrimmage of any sort, there was always the possibility of a chance to snatch something.

As the skua skimmed along, just ahead of him came a puffin, volleying upward from the sea with a particularly fine fish in his beak. The lucky fisherman shot straight to his hole. But, by the finest hairbreadth, the robber got there before him. There was a wild mix-up of wings. The puffin was knocked clean over on his back, losing the fish, which fell just before the next burrow. Like a flash the proprietor of that next burrow bobbed his head forward and snatched at the unexpected windfall. He caught it by the tail, and turned to plunge into the burrow with it. But in that same instant the long beak of the skua caught it by the head. For a second or so the two tugged savagely at the prize, with a vast flapping and squawking. Then the outraged owner, recovering himself, floundered up, fixed his beak in the exposed belly of the fish, and began to pull and jerk like an angry terrier.

Feathers and sand flew into the air as the triangular tug-of-war went on. But frantic as was the turmoil of scuffling and flapping, the near-by ranks of puffins paid no attention to it whatever, except to turn their great beaks, all at the same angle, and stare solemnly, like so many fantastic maskers. The gulls overhead, however, gathered down with excited cries, seeking a chance to take part in the scuffle.

But before they could get their greedy beaks into it, it had come to an end. The fish was torn apart. The puffin who had grabbed the tail fell backwards with it, ruffled but triumphant, into his burrow; the original owner was left with just so much as his beak could hold – fortunately no mean mouthful; while the too-successful marauder, bearing by far the largest share of the prize, beat vigorously aloft through the screaming gulls, who would have tried to rob him had they dared. Rising strongly above them, he headed for the flat ledge, a little inland, where he and his dusky mate had made their nest.

Meanwhile, on the neighboring cliff-face, had just occurred one of those incidents which were forever stirring up excitement among the colonies of the auks and the saddle-backs. It began in the usual way. Each pair of auks, it must be remembered, has but one egg, which is laid, with no pretence of a nest, on the bare narrow ledge. As these eggs lie side by side along the rock, just far enough apart for the parents to brood them, and as they all look amazingly alike, sometimes the owners themselves get mixed up as to the identity of their speckled property. In this instance, two mothers, on a crowded shelf some forty feet above the sea, claimed the same egg, and both insisted on brooding it at the same time. With curious, strident grumblings, deep in their throats, they struggled over it. Their mates, chancing both to return from their fishing at this moment, joined vigorously in the discussion. The egg was promptly rolled off the ledge and smashed on the rocks below. But in the excitement its absence was not noticed. Meanwhile the combatants were making things most uncomfortable for their nearest neighbors, so these presently were dragged into the fight. The unfortunate eggs began dropping over the ledge. Instantly the great saddle-backs, from the noisy colony higher up the cliff, swept down to gather in the juicy harvest. They loved eggs, whether fresh or half brooded. Screaming joyously, they thronged the air just below the scene of the quarrel, which still went on with zest. Some of the tumbling eggs were stabbed cleverly and sucked in mid-air as they fell, while others were devoured or sucked up, according to the stage of development of their contents, on the rocks below. So long did the foolish auks continue their quarrel, so unusual was the rain of eggs, so wild was the screaming of the delighted banqueters below the ledge, that presently a number of the brooding saddle-backs – those who should have stayed by their charges to guard them, whatever their consorts might be doing – were seduced from their too tame responsibilities. Standing up in their dizzy nests, – most of which held either two or three muddy-colored eggs, scrawled with markings of dull maroon, – they stretched their fierce yellow beaks over the brink and peered down with predacious eyes. For many of them the temptation was not to be resisted. With hoarse cries they launched themselves downward, and joined deliriously in the scramble.

About level with the crest of the cliff, some half dozen of the dusky skuas were sailing leisurely. They saw their chance. There was nothing in the world more to their taste than eggs – and particularly the big, rich eggs of the great saddle-back gulls. Down they swooped upon the unguarded nests; and in a moment, plunging their long beaks through the shells, they were feasting greedily. All around them sat the other gulls, by the hundred – faithful ones who had resisted temptation and stuck to their nests. These screamed angrily, but made no attempt to interfere. “Let each look out for his own” was frankly their policy. Before any of the delinquent brooders came back, the skuas had cleared out every unguarded nest, and sailed off with derisive cries.

And so it came about that an unwonted number of saddle-backs, freed from domestic ties until they should be ready to lay new clutches of eggs, but very savage and vindictive for all their release, now came flapping inland over the island on the lookout for any possible chance to avenge themselves.

At this moment the great skua who had robbed the puffin of its fish came in sight of his nest. At his approach the female, who had grown impatient, arose from her handsome, greenish-brown, mottled eggs, sprang into the air, and sailed off toward the sea. For just about ten or a dozen seconds the precious eggs were left exposed, while the male swept down to them on a long, swift glide. But in those brief seconds fate struck. With an exultant yelp a huge saddle-back dropped out of the sky, directly upon the nest, and plunged his beak into one of the eggs. The egg was not far from hatching. He dragged forth the naked chick and swallowed it ravenously. Before he could turn to another egg, the skua had fallen upon him, hurling him clear of the nest, and tearing at him with desperate beak.

Now, the great gull, fully two feet and a half in length from the tip of his punishing yellow beak to the tip of his tail, was not far from twice the size of his fearless and furious assailant. Moreover, having just had his own nest destroyed, he was in a fighting mood. Ordinarily, being a thorough bully, he would have cowered and fled before the skua’s swift rage, but now he turned and struck back savagely. More nimble than he, the skua evaded the blow, and caught him by the neck. And promptly the two became entangled into a flapping, tearing jumble of beaks and feathers.

It was close beside the nest that the struggle went on; but meanwhile the two remaining eggs were lying uncovered to the eyes of prowlers. They did not lie there long. Two more big saddle-backs straightway pounced upon them, crushing them flat in the scuffle. Engrossed though he was, the skua saw them. He was only a shameless robber, but his mettle was of a temper of the finest, and he knew not fear. Tearing himself free from his heavy foe, he pounced frantically upon these new assailants of his home. Startled, they hesitated whether to fight or flee. Then, seeing the odds so far in their favor, they turned to fight. The first saddle-back joining them, they presently succeeded in pulling the skua down. Then against their great weight and overpowering wings, his courage availed him little. Smothered, beaten, trodden upon, he disappeared from sight beneath the yelping turmoil. The odds had been too great for him. In half a minute the battle was over and his dark body, with the throat completely torn out, lay unresisting beneath the broad, pink, heavy-webbed feet of his conquerors.

Suddenly, as if at a signal, all three saddle-backs lifted their heads and stared about them. They marked their victim’s mate winging upward toward them from the sea, swiftly, as if a prescience of evil had summoned her. They saw two other skuas sailing down from the cliff-top, as if to demand their business in skua territory. They had no stomach to face that demand; they had no heart for a fight on anything approaching fair terms. Flapping heavily into the air, they flew off in haste to lose themselves in the myriads of their screaming fellows. The female skua, returning, hovered low; but she did not alight. In silence, her head thrust downwards, she circled and circled endlessly on dark wings above the scattered ruins of her nest, the bedraggled and tattered body of her slain mate. And the stiff ranks of the puffins, like fantastic toy birds carved in wood and painted, stared down upon her solemnly from the slopes near by.
