Charles Roberts - Some Animal Stories

For perhaps ten minutes the great bird stood there without the movement of so much as a feather, apparently unconcerned while the small inhabitants of the swamp made merry in the streaming sunshine. But his full round eyes took in, without stirring in their sockets, all that went on about him, in air, or sedge, or water. Suddenly, and so swiftly that it seemed one motion, his neck uncoiled and his snaky head darted downward into the water near his feet, to rise again with an eight-inch chub partly transfixed and partly gripped between the twin daggers of his half-opened bill. Squirming, and shining silverly, it was held aloft, while its captor stalked solemnly in through the sedges to a bit of higher and drier turf. Here he proceeded to hammer his prize into stillness upon an old half-buried log. Then, tossing it into the air, he caught it adroitly by the head, and swallowed it, his fierce eyes blinking with the effort as he slowly forced it down his capacious gullet. It was a satisfying meal, even for such a healthy appetite as his, and he felt no immediate impulse to continue his fishing. Remaining where he was beside the old log, thigh deep in the young grasses and luxuriously soaking in the sunshine, he fell once more into a position of rigid movelessness. But his attitude was now quite different from that which he had affected when his mind was set on fish. His neck was coiled backwards till the back of his head rested on his shoulders, and his bill pointed skyward, as if the only peril he had to consider seriously during his time of repose might come, if at all, from that direction. And though he rested, and every nerve and muscle seemed to sleep, his gem-like eyes were sleeplessly vigilant. Only at long intervals a thin, whitish membrane flickered down across them for a fraction of an instant, to cleanse and lubricate them and keep their piercing brightness undimmed.

Once a brown marsh-hawk, questing for water-rats, winnowed past, only ten or a dozen feet above his head. But he never stirred a muscle. He knew it would be a much more formidable and daring marauder than the marsh-hawk that would risk conclusions with the uplifted dagger of his bill.

In about half-an-hour – so swift is the digestion of these masters of the swamp – the bittern began to think about a return to his easy and pleasant hunting. But, always deliberate except when there was need for instant action, at first he did no more than uncoil his long neck, lower his bill to a level, and stand motionlessly staring over the sedge-tops. One of the big red-and-black butterflies came wavering near, perhaps under the fatal delusion that that rigid yellow bill would be a good perch for him to alight on. A lightning swift dart of the snaky head; and those gay wings, after curiously adorning for a moment the tip of the yellow bill, were deftly gathered in and swallowed – an unsubstantial morsel, but not to be ignored when one is blest with a bittern's appetite.

After a few minutes more of statuesque deliberation, having detected nothing in the landscape particularly demanding his attention, the bittern lazily lifted his broad wings and flapped in slow flight, his long legs almost brushing the sedge-tops, back to the post of vantage where he had captured the chub. As soon as he alighted he stiffened himself erect, and stared about as if to see whether his flight had been noticed. Then, presently, he seemed to remember something of importance. This was the season of mating joys and cares. It was time he signalled his brown mate. First he began snapping his bill sharply, and then he went through a number of contortions with his throat and neck, as if he were trying to gulp down vast quantities of air, and finding the effort most difficult. At length, however, the painful-looking struggle was crowned with achievement. Once more, as on the preceding evening, that great call boomed forth across the swamp, sonorous yet strangulated, uncouth yet thrilling and haunting, the very voice of solitude and mystery: — Klunk-er-glungk – Klunk-er-glungk – Klunk-er-glungk .

Almost immediately came an acknowledgement of this untuneful love-song – a single hoarse quaw-awk ; and another snaky brown head and yellow dagger bill were raised above the tops of the sedges. The hen bittern, in response to her mate's cry, had just come off her nest.

For some tranquil moments the two eyed each other without stirring, and it almost seemed as if their very immobility was a mode of expression, a secret code for communication between them. The result, if so, appeared to be satisfactory. The hen came stalking solemnly through the grass and sedges towards the water's edge, only pausing on the way to transfix and gulp down a luckless frog. And the stately male, once more spreading his spacious vans, flapped slowly over and dropped again into the grass some ten or a dozen feet from the nest.

The nest was a rather casual structure of dry grass and weeds, in a hollow of the turf, and more or less concealed by leaning tufts of swamp-grass. It contained three large eggs of a dull greenish buff, clouded with darker tones, and blending elusively with the soft colourings of the nest. These precious eggs the male bittern had no intention of brooding. His object was merely to stand guard over them, with jealous vigilance, while his mate was away foraging. The sun was softly warm upon them, through the thin shadows of the grass blades, and he knew they would not chill during her brief absence. He took his post just near enough to keep his eye upon the nest, without unduly drawing attention to its hiding-place.

This patch of water-meadow, perhaps a half-acre in extent, on which the bitterns had their nest, was one of many such tiny islands scattered amid the interlacing channels of Lost-Water Swamp. It formed a congenial refuge for all that small life of the wilderness which loves to be near water without being in it. It was particularly beloved of the meadow-mice, because the surrounding watercourses and morasses were an effectual barrier to some of their worst enemies, such as foxes, skunks, and weasels; and they throve here amazingly. To be sure the bittern would take toll of them when they came his way, but he did not deliberately hunt them, rather preferring a diet of frogs and fish; and moreover, his depredations upon the mice were more than counterbalanced by his eager hostility to their dreaded foes, the snakes. So, on the whole, he might have been regarded by the mouse community as a benefactor, though a rather costly one.

Even now, as he stood there apparently thinking of nothing but his guardianship of the nest, he gave a telling example of his beneficence in this regard. There was a tiny, frightened squeak, a desperate small rustling in the grass-stems, and a terrified mouse scurried by, with a two-foot black snake at its tail. The bittern's head flashed down, unerringly, and rose again, more slowly, with the snake gripped by the middle. Held high in air, as if on exhibition, between the knife-edge tips of that deadly yellow bill, the victim writhed and twisted, coiling itself convulsively around its captor's head and neck. But with two or three sharp jerks it was drawn further back, towards the base of the mandibles, and then, with an inexorable pressure, bitten clean in two, the halves uncoiled and fell to the ground, still wriggling spasmodically. With grave deliberation the bittern planted one foot upon the head half, and demolished the vicious head with a tap of his bill. This done, he swallowed it, with determined and strenuous gulpings. Then he eyed the other half doubtfully, and decided that he was not yet ready for it. So, placing one foot upon it with a precise air, as if in assertion of ownership, he lifted his head again and resumed his motionless guarding of the nest. If any mice were watching – and their beady bright eyes are always watching – they may well have congratulated themselves that the pair of bitterns had chosen this particular island for their nesting-place.
