The Confessions of a Beachcomber

by E. J. Banfield

Another occupant of this nestful tree is the sulphur-crested cockatoo, whose eggs are laid deep down in a hollow. Two or three hundred of the shining colonists, a brood of sea-eagles, white-headed, snowy-breasted and red-backed, and a couple, perhaps, three, screeching white cockatoos, represent the annual output of this single tree, in addition, of course, to its own crop of sweet savoured flowers (on which birds, bees, beetles and butterflies, and flying-foxes feast) and seeds in thousands in cunning cups.

"STATELY FACE AND MAGNANIMOUS MINDE"

How feeble and ludicrous are the voices of the fierce hawks and eagles. The white-headed sea-eagle's puking discordant twang, the feeble cheep of the grey falcon—the cry of a sick and scared chicken—the harsh protest of the osprey, are sounds distinctive but frail, conveying no notion whatever of the demeanour and characteristics of the birds.

Now the white-headed sea-eagle, with its sharp incurved beak, terrible talons, and armour-plated legs, is a friend to all the little birds. He has the "stately face and magnanimous minde" that old writers were wont to ascribe to the Basilisk, the King of Serpents. They know and respect, almost venerate him. A horde of them never seeks to scare him away with angry scolding and feeble assaults, as it does the cruel falcon and the daring goshawk. Domestic fowls learn of his ways, and are wise in their fearlessness of him. But I was not well assured of the reasons for the trustfulness and admiration of the smaller birds for the fierce-looking fellow who spends most of his time fishing, until direct and conclusive evidence was forthcoming. Two days of rough weather, and the blue bay had become discoloured with mud churned up by the sea, and the eagle found fishing poor and unremunerative sport. Even his keen eyesight could not distinguish in the murky water the coming and going of the fish. just below the house is a small area of partly cleared flat, and there we saw the brave fellow roaming and scooping about with more than usual interest in the affairs of dry land. At this time of year green snakes are fairly plentiful. Harmless and handsome, they prey upon small birds and frogs, and the eagle had abandoned his patrol of the sad-hued water to take toll of the snakes. After a graceful swoop down to the tips of a low-growing bush, he alighted on the dead branch of a bloodwood 150 yards or so away, and, with the help of a telescope, his occupation was revealed—he was greedily tearing to pieces a wriggling snake, gulping it in three-quarter-yard lengths. Here was the reason for the trustfulness and respect of the little birds. The eagle was destroying the chief bugbear of their existence—the sneaking greeny-yellowy murderer of their kind and eater of their eggs, whose colour and form so harmonises with leaves and thin branches that he constantly evades the sharpest-eyed of them all, and squeezes out their lives and swallows them whole. But the big red detective could see the vile thing 50 and even 100 yards away, and once seen—well, one enemy the less. Briskly stropping his beak on the branch of the tree on which he rested, and setting his breast plumage in order, much as one might shake a crumb from his waistcoat, the eagle adjusted his searchlights and sat motionless. In five minutes a slight jerk of the neck indicated a successful observation, and he soared out, wheeled like a flash, and half turning on his side, hustled down in the foliage of a tall wattle and back again to his perch. Another snake was crumpled up in his talons, and he devoured it in writhing, twirling pieces. The telescope gave unique advantage during this entertainment, one of the tragedies of Nature, or rather the lawful execution of a designing and crafty criminal. Within ten minutes the performance was repeated for the third time, and then either the supply of snakes ran out or the bird was satisfied. He shrewdly glanced this way and that, craning and twisting his neck, and seeming to adjust the lenses of his eyes for near and distant observation. No movement among the leaves seemed to escape him. Two yards and a half or perhaps three yards of live snakes constituted a repast. At any rate, after twenty minutes' passive watchfulness, he sailed up over the trees and away in the direction of his home in the socialistic community of the shining calornis.

The white-headed sea-eagle is a deadly foe to the pugnacious sea-serpent also. On the beach just above high water-mark was the headless carcase of one that must have been fully 5 feet long, and while it was under inspection an eagle circled about anxiously. Soon after the intruders disappeared the bird swooped down and resumed his feast, and presently his mate came sailing along to join him. The snake must have weighed several pounds, and apparently was not as dainty to the taste as the green arboreal variety, for after two days' occasional feasting there was still some of the flesh left.

Shrewd as is the observation of the white-headed sea-eagle he is not exempt from blunders. Though he pounces with authoritative certainty and precision, he does not discriminate until the capture is complete, between the acceptable and the unacceptable. Generally whatsoever is seized is carried off, apparently without inspection. Perhaps the balloon fish is the only one that is promptly discarded. The sea porcupine (DIODON), which shares with that repugnant creature the habit of exemplifying the extent to which the skin of a fish is capable of distention without bursting, is frequently picked up from the shallow water it favours. Short sharp needles stand out rigidly from its skin, forming a complete armament against most foes. The sea-eagle does not always devour the sea porcupine, which at the very best is nothing more than a picking. Amongst such a complex labyrinth of keen bones a hasty meal is not to be found, and the sea-eagle is not a leisurely eater. He likes to gulp; and so when he has indiscreetly blundered on a porcupine he frequently unlocks his talons and shakes himself free, while the fish, inflated to the last gulp, floats away high and light, bearing on its tense silvery-white side the crimson stigmata of the sea-eagle.

When misguided fish have blundered into the trap in the corner of the bay, the sea-eagle demands a share of the easily-gotten spoil. Perched on the tallest stake, he faithfully indicates the presence of food that he cannot obtain unless by goodwill; yet who would deny the bird of his right? Having fulfilled his duty as sentinel, he soars to an adjacent tree, uttering that sneering twang which is his one paltry attribute, and when a fish is thrown into the shallow water he swoops down and is away with it to his eyrie. If the sand is bare, however, he cannot, owing to his length of wing, pick up the fish in his flight. Unbecoming as it may be to tantalise by trickery so regal a bird, a series of trials was undertaken to ascertain the height from the surface whence a fish could be gripped. Twelve successive swoops for a mullet flopping on the sand failed, though it was touched at least six times with the tips of the eagle's outstretched talons. Consenting to failure, the bird was compelled to alight undignifiedly a few yards away, to awkwardly jump to the fish and to eat it on the spot, for however imperious the sea-eagle is in the air, and dexterous in the seizure of a fish from the water, he cannot rise from an unimpressionable plane with his talons full. On another occasion a fish was raised 4 inches on a slender stake. The sea-eagle dislodged it several times, but could not grasp it. Raised a further 4 inches the fish was seized without fumbling. Eight inches or so, therefore, seems to be about the minimum height from which a bird with 6 feet of red wing and a nice determination not to bruise or soil the tips, may grip with certainty.

WHITE NUTMEG PIGEON

No birds of the air which frequent these parts attract more attention than the white nutmeg or Torres Straits pigeons (MYRISTICIVORA SPILORRHOA), which resort to the islands during the incubating season. White with part of each flight feather black, and with down of pale buff, it is a handsome bird, strong and firm of flesh, and possesses remarkable powers on the wing. Half of the year is spent with us. They come from the north in their thousands during the first week of September, and depart during March. While in this quarter they seek rest and recreation, and increase and multiply on the islands, resorting to the mainland during the day for food. Their flights to and from are made in companies varying from four to five to as many as a hundred—but the average is between thirty and forty. Purpose and instinct guide them to certain islands, and to these the companies set flight. Towards the end of the breeding season, when the multitude has almost doubled its strength by lusty young recruits, for an hour and more before sunset until a few minutes after, there is a never-ending procession from the mainland to the favoured islands—a great, almost uncountable host. Soon some of the tree-tops are swaying under the weight of the masses of white birds, the whirr and rush of flight, the clacking and slapping of wings, the domineering "coo-hoo-oo" of the male birds and the responsive notes of the hens; the tumult when in alarm all take wing simultaneously and wheel and circle and settle again with rustling and creaking branches, the sudden swoop with whistling wings of single birds close overhead, create a perpetual din. Then as darkness follows hard upon the down-sinking of the sun, the birds hustle among the thick foliage of the jungle, with querulous, inquiring notes and much ado. Gradually the sounds subside, and the subdued monotonous rhythm of the sea alone is heard.

An endeavour, from the outset destined to be futile, has been made each season in succession, to estimate the number of nutmeg pigeons passing a given point per minute on their evening flight. With so methodical a bird, it was to be expected that the companies would have favoured points of departure from the mainland, and would fly along precise routes to a common destination. There are thousands of stragglers all along the coast, but the main bodies keep to particular routes. Most of those which rest on the islands in this neighbourhood quit the mainland between Clump Point and Tam o' Shanter, the trend of numbers being toward the latter point. Six miles separate these headlands, but the channel between Tam o' Shanter and Dunk Island is little more than 2 1/2 miles, so that the pigeons here become concentrated to a certain extent. Early in the season they pass Dunk Island at the rate of about 300 per minute, during the hour and a half preceding sunset. To speak more definitely, but well within the mark, those flying south, easily within range of sight from the sand spit here, may be calculated at something like 27,000. But in reality the procession of birds may cover a breadth of 2 miles, while only those flocks nearest to the observer are included in the estimate. No doubt, fully 100,000 come and go evening and morning. When the incubating season is at its height the number lessens; when all the young are hatched the unmarshalled procession trails along with but brief intervals between the companies—some flying low over the water, others high and wide.
