The swamp pheasant, or pheasant coucal (CENTROPUS PHASIa.n.u.s) is also an early bird, and a bird of varied linguistic capabilities. Folks are apt to a.s.sociate with him but one note, and that resembling the mellow gurgle of cream from a bottle, "Glooc! glooc! glooc! glooc!" An intimate knowledge of his conversational powers leads one to conclude that there are few birds more widely accomplished in that direction. He does use the fluid phrase mentioned, but his notes and those of his consort cover quite a range of exclamations and calls. Just as I write a pair appeal for a just recognition of their accomplishments. That which I a.s.sume to be the lord and master utters a loud resonant "Toom! toom! toom! toom"
a smooth trombonic sound, "hollow to the reverberate hills," which his consort answers with a series of "Tum! tum tum! tum!" on a higher but still harmonious key, and in accelerated tempo. This, I fancy, is the lover"s serenade, and the soft a.s.senting answer; almost invariably the loud hollow sound is the opening phrase of the duet. "Sole or responsive to each other"s note," the birds make the forest resound again during the day, especially in the prime months, and even these notes find varied and pleasing expression. Free and joyous as a rule, occasionally they seem to indicate sadness and gloom. During and after a bush fire the birds give to the notes a mournful cadence like the memories of joy that are past, a lament for the destruction of the gra.s.s among which last year"s dome-shaped nests were hidden. The swamp pheasant also utters a contented, self-complacent chuckle, that resembles the "Goo! goo! goo!" of a happy infant, and occasionally a succession of grating, discordant, mocking sounds, "Tcharn! tcharn! tcharn!" The chuckle may be an expression as if gloating over the detection and a.s.similation of some favourite dainty, and the harsh notes a demonstration of rivalry, anger and hostility. The more familiar and more frequent note is the "Toom," repeated about fourteen or sixteen times, and the thinner, softer response.
The bird resembles in plumage a pheasant. c.u.mbersome and slow of flight, clumsy in alighting, he frequently loses his equilibrium, and is compelled to use his long tail as a counter-balance, as he jumps from branch to branch ascending a tree, in order to gain elevation, whence to swoop and flop across the intervening s.p.a.ce to the next. When compelled to take wing from a low elevation, the flight is slow and laboured in the extreme. He is a handsome fellow, the ruling colours being glossy black, brown and reddish chestnut. One writer describes the bird as half hawk, half pheasant, another as a non-parasitic cuckoo; another "really a cuckoo"; another a swamp or tree parrot with the foot of a lark. Without daring to attempt to dispute any of these descriptions, I may say that the bird is a decided character and possesses the charm of originality.
He has become so confiding that he will perch on the gatepost as one enters, a.s.suming a fierce and resentful aspect, and he will play "hawk"
to the startled fowls. He eats the eggs of other birds and kills chicks; but his murderous instincts are rarely exhibited, and then only, perhaps, when his pa.s.sions are aroused. He does not (as far as my observation goes) kill for food, but merely because Nature gives him at certain times and seasons a fiery, jealous disposition, and a truculent determination to protect his family.
"GO-BIDGER-ROO!"
As the sun shines over the range, the plaintive cooing of the little blue dove, such as picked the rice grains from the bowl beside rapt Buddha"s hands, comes up from among the scented wattles on the flat, the gentlest and meekest of all the converse of the birds. The nervous yet fluty tones are as an emphatic a contrast to the vehement interjections and commands of the varied honey-cater (PTILOTIS VERSICOLOR)--now at the first outburst--as is the swiftly foreshortening profile of the range to the glare in which all the foreground quivers.
Once aroused, the varied honey-eater is wide awake. His restlessness is equalled only by his impertinent exclamations. He shouts his own aboriginal t.i.tle, "Go-bidger-roo!" "Put on your boots!"
"Which--which-which way-which way-which way you go!" "Get your whip!" "Get your whip!" "You go!" "You go!" "None of your cheek!" "None of your cheek!" "Here-here!" And darts out with a fl.u.s.ter from among the hibiscus bushes on the beach away up to the top of the melaleuca tree; pauses to sample the honey from the yellow flowers of the gin-gee, and down to the scarlet blooms of the flame tree, across the panda.n.u.s palms and to the shady creek for his morning bath and drink, shouting without ceasing his orders and observations. He is always with us, though not always as noisy as in the prime of the year--a cheerful, prying, frisky creature, always going somewhere or doing something in a red-hot hurry, and always making a song of it--a veritable babbler. His love-making is pa.s.sionate and impulsive, joyous almost to rowdyism.
BULLY, SWAGGERER, SWASHBUCKLER
The drongo shrike is another permanent resident; glossy black, with a metallic shimmer on the shoulders, long-tailed, sharp of bill and masterful. He has a scolding tongue, and if a hawk hovers over the bloodwoods he tells without hesitation of the evil presence. He is the bully of the wilderness of leaves, bouncing birds vastly his superior in fighting weight and alertness of wing, and clattering his jurisdiction to everything that flies. When the nest on the nethermost branch of the Moreton Bay ash is packed with hungry brood, his industry is exhilarating. Ordinarily he gets all the food he wants by merely a superficial inspection; but with a family to provide for, he is compelled to fly around, shrewdly examining every likely looking locality. Clinging to the bark of the bloodwood, with tail spread out fan-wise as additional support, he searches every interstice, and ever and anon flies to the Moreton Bay ash, and tears off the curling fragments of crisp bark which afford concealment to the smaller beetles, grubs and spiders.
With the loose end of bark in his bill, tugging and fluttering, using his tail as a lever with the tree as a fulcrum, and objurgating in unseemly tones, as the bark resists his efforts, the drongo a.s.sists the Moreton Bay ash in discarding worn-out epidermis, and the tree reciprocates by offering safe nesting-place on its most brittle branches.
The drongo is a bird of many moods. Silent and inert for months together, during the nesting season he is noisy and alert, not only the first to give warning of the presence of a falcon, but the boldest in chiveying from tree to tree this universal enemy.
He is then particularly partial to an aerial acrobatic performance, unsurpa.s.sed for gracefulness and skill, and significant of the joy of life and liberty and the delirious pa.s.sion of the moment. With a mighty effort, a chattering scream and a preliminary downward cast, he impels himself with the ardour of flight--almost vertically--up above the level of the tree-tops. Then, after a momentary, thrilling pause, with a gush of twittering commotion and stiffened wings preternaturally extended over the back and flattened together into a single rigid fin, drops--a feathered black bolt from the blue--almost to the ground, swoops up to a resting-place, and with bowing head and jerking tail gloats over his splendid feat.
Though denied fluency of utterance, the spangled drongo has no rival in the peculiar character of the notes and calls over which he has secure copyright. The shrill stuttering shriek which accompanies his aerial acrobatic performances, the subdued tinkling tones of pleasure, the jangle as of cracked china, the high-pitched tirade of jarring abuse and scolding at the presence of an enemy, the meek cheeps, the tremulous, coaxing whistles when the young first venture from the nest--each and every sound, unique and totally unlike that of any other bird, indicates the oddity of this sportful member of the crow family.
EYES AFLAME
Perhaps the most interesting and entertaining of all the birds of the island is that commonly known as the weaver or friendly bird, otherwise the metallic starling, the shining calornis of the ornithologist, the "Tee-algon" of the blacks. Throughout the coastal tract of North Queensland this bird is fairly familiar. In these days it could not escape notice and comment, for it is an avowed socialist establishing colonies every few miles. There are four on Dunk Island, and though not permanent residents, spending but little more than half the year with us, they are among the few birds who have permanent homes. In some lofty tree they build perhaps two hundred nests in groups of from two to six. With all these nests weighting its thinner branches the tree may look wearied and afflicted, but it obtains direct benefit from the presence of the birds. The nests, deftly built of tendrils and slender creepers and gra.s.s are domed, the entrance being at the side, and so hidden and overhung as almost to escape notice. Each August the birds appear, coming from the north. and until the middle of March, when they take their departure, they do not indulge in many leisure moments. There are the old nests to renovate and new ones to build in accordance with the demand of the increasing population, and loads of fruits and seeds and berries to be conveyed from the jungle to the colony. The shining calornis is a handsome fellow, gleaming black, with purple and green sheen. The live bird differs so greatly from the dull, stuffed specimen of the museum that one is tempted to endeavour to convey by similitude its wonderful radiance. A soap bubble, black yet retaining all its changing lights and flashing reflections, is the nearest approach to a just description, and then there are to specify the rich, red eyes, eyes gleaming like polished gems. Until after the first year of their existence the young are brown-backed, and mottled white and bluish-grey of breast, and would hardly be recognised as members of the colony, but for the shrill notes and restless activity and those flaming eyes--living gems of wondrous radiance, and the eyes epitomise the life of the bird which is all flame and fever.
Twenty or thirty may be peering about in a bloodwood, and with a unanimous impulse and a call in unison they slip through the forest, and shoot into the jungle, flashing sun-glints. Eager, alert, always under high pressure, the business of the moment brooks of no delay. The flocks come and go between the home and the feeding-ground with noisy exclamations and impetuous haste. With whirr of wings and jeering notes they swoop close overhead, wheeling into the wilderness of leaves with the rapidity of thought, and with such graceful precision that the sunlight flashes from their shoulders as an arc of light. Work, hasty work, is a necessity, for their wastefulness is extreme, or, rather, do they not unconsciously perform a double duty, being chief among the distributing agents--industrious and trustworthy though unchartered carders for many helpless trees. When the company darts again out of the jungle, each with a berry in its bill and each shrilly exulting, many a load is dropped by the way, and many another falls to mother earth in the act of feeding the clamorous young. Berries and seeds having no means of self-transportation are thus borne far from parent trees to vegetate in sweet unenc.u.mbered soil. Other birds take part in this generous dispersal, but none engage in it so systematically or so openly.
Beneath the tree which is the head centre of the colony is a carpet of debris several inches thick. Old and discarded nests, fragments of unused building materials, the nutmeg with its lacing of coral-red mace, the blue quandong, the remains of various species of figs, hard berries, chillies, degenerated tomatoes, the harsh seed-vessels of the umbrella-tree, samples of every fruit and berry of attractive appearance, however hot and acrid, all go to form a mulching of vegetable matter such as no other tree of forest or jungle gets. Prodigal and profuse as she may be, Nature is the rarest of economists. Out here in the forest is springing up an oasis of jungle, every plant of which owes its origin to the shining calornis.
It must not be thought that all the notes of these most engaging birds, symbolic of light in plumage and in flight, are shrill and strident. When they feed--and they seem always to be feeding or carrying food--their chatter is perpetual and varied in tone. Occasionally a male bird sets himself to beguile the time with song. Then his flame-red eyes flash with ardour, his head is thrown back, a sparkling ruffle appears on his otherwise satiny smooth neck, and the tune resembles that of a well-taught canary--more fluty but briefer. But the song is only for the ears of those who know how to overcome timidity and shyness. Birds naturally so impetuous are restless and uneasy under observation. One must pose in silence until his presence is forgotten or ignored. Then the delicious melody, the approving comments of the songster"s companions, and the efforts of ambitious youngsters to imitate and excel, are all part of a quaint entertainment.
THE NESTFUL TREE
All the forest brood do not plot mutual slaughter. Some live in strict amity. Here in the Moreton Bay ash, taken advantage of by the shining calornis, a white-headed, rufous-backed sea-eagle nests, and the graceful, fierce-looking pair come and go among the glittering noisy throng without exciting any special comment. Of course it would be impossible to detect any certain note of remonstrance, for the smaller birds are generally commenting on something or other in acidulous tones.
Another occupant of this nestful tree is the sulphur-crested c.o.c.katoo, 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 c.o.c.katoos, 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 b.u.t.terflies, 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 tw.a.n.g, 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 a.s.saults, 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 a.s.sured 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 const.i.tuted a repast. At any rate, after twenty minutes" pa.s.sive 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 tw.a.n.g 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 mult.i.tude has almost doubled its strength by l.u.s.ty 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 ma.s.ses 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 pa.s.sing 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 pa.s.s 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.
Great as the company of birds seems, it is small compared with the myriads that favoured the islands in years gone by. Pioneers tell of the days when blacks were wont to make regular expeditions, returning to the mainland with canoes ladened with fledglings and eggs, which in accordance with tradition were devoured by the older men and women. The youngsters of the tribes were nurtured in the belief that if they partook of such luxuries all the pigeons would fly away never to re-visit their haunts. Strange as it may seem, the vast quant.i.ties eaten by the blacks did not seem to decrease the numbers. But since the advent of the white man, with his nerve-shattering gun, a remarkable diminution has been observed in some localities. No doubt it could be successfully maintained that the gun is responsible for an insignificant toll compared with that taken by the blacks of the past. But the birds were then deprived of their nestlings and eggs quietly, if remorselessly, while the noise of the gun is more demoralising to the species as a whole than the numbers actually killed.
Nutmeg pigeons are frequently shot by the hundred as they reach their nesting-place and ma.s.s themselves on the trees. Some of their nurseries lie far away from the usual tracks of the sportsman. Yet a single expedition during the breeding season to one of the islands may cause immense destruction and unprofitable loss of life. Though in lessening numbers they venture much further along the coast to the south, they keep well within the tropical zone. The most favoured resorts within many miles are the Barnard Islands, 14 miles to the north of Dunk Island. The whole of the tribes, therefore, though scattered for feeding over an immense area of the coast congregate on four or five islands--miles apart--to rest and breed. The a.s.semblages are indeed prodigious; but they represent the gathering together of clans which have a very wide dispersal. Crowded together the host appears innumerable, but on the mainland during the day (when only the hen birds stay at home) the pigeons seem scarce. An occasional group may be met with, and they may be heard fluttering and flapping on the tree-tops (they are generally silent when feeding), but they are too thinly distributed to afford sport. Any other species of native bird which took to gregarious habits might seem as numerous as this. If all the sulphur-crested c.o.c.katoos, scrub turkeys, and scrub fowls scattered over an area of the mainland corresponding in extent with the feeding-ground of the nutmeg pigeons were ma.s.sed each night in four or five communities, the numbers would seem startling; but because the poor pigeon, conspicuous and heedless, has the instinct or habit of a.s.sociation, it is argued that they outnumber all the other birds, that their legions are infinite, and that that fact is sufficient licence for the destruction of thousands during the breeding season.
Compared with some species, nutmeg pigeons may be considered scarce, although their breeding establishments extend over hundreds of miles of the eastern coast of North Queensland. But it must be remembered that the birds breed only on the islands. To preserve them effectually certain islands should be proclaimed sanctuaries, and genuine sportsmen will never indulge their propensities when haunted by the thoughts of the consequent cruelty.
There are many contradictory statements in popular natural history works with reference to the habits of this bird, and it may not be out of place to quote what one authority says:--
"This singularly shy bird has acquired its popular name from the well-remarked habit it has of exclusively frequenting the wild nutmeg tree (MYRISTICA), in the tops of which it may be said to pa.s.s its life, except during the brief pairing season. Then it commonly selects the denser scrub or the mangroves, most probably guided by their contiguity to fresh water. Here it makes its nest, a more than ordinarily careless structure, the few crossed sticks barely sufficing to prevent the single egg it is destined to receive, from falling through to the ground. The fruit of the nutmeg is undoubtedly swallowed whole by the bird, and to the powers of deglut.i.tion is left the separation of the nutritive portion which we know as mace, from the hard and indigestible nut which is voided in flight. Thus this elegant little creature becomes the useful means of disseminating the remarkable nutmeg-tree, and it is found that some chemical treatment corresponding to that which it undergoes during sojourn within the body of the bird, is actually necessary before the nut can be fertilised and induced to take root. So strictly arboreal is this pigeon in its habits that it is questionable if it ever alights upon the ground, and so timid that it is impossible to procure specimens unless stratagem is resorted to."
Some years of repeated observation enable me to offer certain amendments to this narrative, evidently written by one who has been impressed by half the life-history of the bird--the half spent on the mainland. The food of the nutmeg pigeon is multifarious. All sorts of nuts and seeds, and even fruits are consumed--quandongs, various palm seeds (including those of the creeping palm or lawyer vine, CALAMUS), nutmeg (MYRISTICA INSIPIDA, not the nutmeg of commerce, though resembling it), the white hard seeds of the native cabbage (SCOEVOLA KOENIGII), the Burdekin plum (PLEIOGYNIUM SOLANDRI), and all sorts of unpromisingly tough and apparently indigestible, innutritious woodeny nuts and drupes. Moreover, it fattens on such diet, but still the wonder grows at the happy provision which enables nuts proportionately of such enormous size to be swallowed by the bird, and ejected with ease after the pulp or flesh has been a.s.similated. As the birds alight on the island after their flight from the mainland, a portion of the contents of the crop seems to be expelled. A shower of nuts and seeds comes pattering down through the leaves to the ground as each company finds resting-place. Perhaps those only who are suffering from uncomfortable distention so relieve themselves. The balance of the contents of the crops seem to go through the ordinary process of digestion. Thus, by the medium of the pigeons, there is a systematic traffic in and interchange of seeds between the mainland and the islands. The nutmeg pigeon resorts to islands where there is no fresh water, and builds a rude platform of twigs, and occasionally of leaves, on all sorts of trees, in all sorts of localities. Palms and mangroves, low bushes, rocky ledges, saplings, are all favoured, no particular preference being shown. It rears generally two, but sometimes three young, one at a time, during the long breeding season, which continues from the end of September until the end of January, and for each successive egg a fresh carpet of twig or leaves is spread. A rare nest was composed of fresh leaves of the Moreton Bay ash, with the petioles towards the centre, forming a complex green star. No doubt the arrangement of the leaves was accidental, but the white dumpy egg as a pearl-like focus completed a quaint device. Another egg reposed carelessly at the base of a vigorous plant of DENDOBRIUM UNDULATUM, the old-gold plumes of the orchid fantastically shading it.
Those pigeons who elect to incubate on the ground discard even the rude platform of twigs, which generally represents the nest of those who prefer bushes and trees, but gradually encircle themselves with tiny mounds of ejected seeds, until the appearance of a nest is presented. At the termination of the breeding season these birthplaces of the young are indicated by circular ramparts, in the composition of which the aromatic nutmeg predominates. Personal experiments on the spot prove that these nutmegs germinate less readily than those taken direct from the tree.
Planted with the red mace still adherent the nuts are quite reliable; others which have been swallowed by the pigeon and ejected, though submitted to like conditions, fail in considerable proportion. So that the oft-repeated theory that the Queensland nutmeg requires primarily to undergo some chemical process similar to that which takes place in the crop of the pigeon to ensure germination, has no foundation whatever in fact. The part the pigeon performs is to transport the nut to free, unstifled soil.
No bird is more precise and punctual in its visits. It comes to its nesting-places and departs with almost almanac-like regularity. It is a large bird as pigeons go, and becomes wonderfully tame and trustful when undisturbed. Specimens may be procured in thousands. Blacks, understanding their habits, climb particular trees known to be well patronised, and as the birds swoop down to rest, kill them easily with a swoop of a long slender stick, or hurl nulla-nullas into the home-coming flocks, just as they alight. It is not a good table bird, the flesh being dark, tough, and of an earthy flavour--far inferior to the generality of pigeons, and not to be compared with ground or aquatic game.
FRUIT-EATERS
The tyrannical fig-tree of the species referred to elsewhere, in full fruit--pink in colouring until it attains purple ripeness--attracts birds from all parts, and for nearly a quarter of the year is as gay as a theatre. From sunset to sunrise birds feast and flirt with but brief interludes. A general dispersal of the a.s.semblage occurs only in the tragic presence of a falcon, whose murderous deeds are transiently recorded by stray painted feathers. But the fright soon pa.s.ses, and the magnificent fruit pigeon--green, golden-yellow, purplish-maroon, rich orange, bluish-grey, and greenish-yellow, are his predominant colours--resumes his love-plaint in bubbling ba.s.s. "Bub-loo, bub-loo maroo," he says over and over again in unbirdlike tone, without emphasis or lilt. "Bub-loo, bub-loo maroo," a grievance, a remonstrance and a threat in one doleful phrase; but to the flattered female it is all compliment and gallantry. That other, known as the allied--so like his cousin that his dissonant accents, "quok--quok--quoo," are more to be relied upon as ready means of identification than any striking difference in plumage; the white-headed, the pheasant-tail, the gorgeous "superb,"
the tranquil dove, Ewing"s fruit pigeon--most timorous of the order--are regular patrons, and each of the family has the distinctive demeanour and note. All save the allied--which is too full of a.s.surance and fruit to be disconcerted by the presence of man--may flutter into the jungle, and then, as the momentary disturbance subsides, a study, whimsical and rich, begins.
With one exception the fruit pigeons, however gay the colouring of the throat and breast and under parts generally, are green of back, that pa.s.sing falcons may be deceived by resemblance to leafy environment. Yet the "superb" and Ewing"s and Swainson"s have the richest of crowns--crowns pink, or shimmering rosy purple. Why this fanciful decoration if not to carry the delusion further by resemblance to a flower?
These glorious pigeons are but a few of the many birds that come to the tree with its millions of pink figs, and enliven the scene with soft notes and eager whistles. Varied and fasciated honey-eaters, black and white, and Jardine"s caterpillar-eaters, the tiny swallow dicaeum, in a tight-fitting costume of blue-black and red (who must bruise and batter the fruit to reduce it to gobbling dimensions), the yellow white-eye (who pecks it to pieces), the white-bellied and the varied graucalus, the drongo, the shining calornis--these and others have been included time after time in the one enumeration.
c.o.c.katoos do not visit the fig-trees as systematically as might be expected. When they come they waste almost as lavishly as the flying foxes at night, nipping off branchlets and dropping them after eating but two or three of the figs.
When the grey falcon soars overhead the birds display varied forms of strategy. The inconspicuous pigeons crouch motionless but alert, their eyes fixedly following the circles of the enemy; the readily detected graucalus fly straight to a forest tree, whence there is a clear get-away; the companies of yellow white-eyes, with a unanimous note of alarm, dart into the jungle; the caterpillar-eaters and the honey-eaters, peering about, drop discreetly down among the lower branches, and silence prevails.
No serious heed is taken of the white-headed sea-eagle. Though the fruit-eaters do not recognise the lordly fellow on the instant of his appearance, he may perch on the topmost branches of the tree to scrutinise the shallows, and they will resume their feasting and noise.
But a falcon is as a death"s-head, and alas! too often a sanguinary disturber of the peace, as the tufts of painted feathers tell.
AUSTRALIA"S HUMMING-BIRD
One of the most self-a.s.sertive of birds of the island is also one of the least--the sun-bird (CINNYRIS FRENATA). Garbed in rich olive green, royal blue, and bright yellow, and of a quick and lively disposition, small as he is, he is always before his public, never forgetful of his appearance, or regardless of his rights. Feeding on honey and on insects which frequent honey-supplying flowers, the sun-bird is generally seen amid surroundings quite in keeping with the splendour of his plumage. The best part of his life is pa.s.sed among blossoms, and he seems to partake of their beauty and frailness. The gold of the gin-gee, the reds of the flame-tree, the umbrella-tree, and of the single and double hibiscus are reflected from his shining feathers, as he flutters and darts among the blooms, often sipping on the wing after the habit of the humming-bird--which he resembles even to the characteristic expansion of the tail feathers. When in September the flame-tree is a dome of red, sun-birds gather by the score--the gayest of all the revellers. Uncommon length of bill enables them to probe recesses of flowers forbidden others, and they seem proud of the superiority. The varied-honey-eater visits flower after flower with something of method. The sun-bird flashes from raceme to raceme, sampling a dozen blooms, while his noisy rival sips with the air of a connoisseur at one. There is a spell in the nectar of the flame-tree as irresistibly attractive to taste of birds as the colour is to the sight of man. Although the tree bursts into bloom with truly tropical ardour, they await the coming banquet with unaffected impatience. Then one of the prettiest frolics of the sun-bird is revealed. Time cannot lag with such gay, saucy creatures, so while they wait half a dozen or more congregate in a circle and with uplifted heads directed towards a common centre sing their song in unison. Whether the theme of the song is of protest against the tardiness of the tree, or of thanks in antic.i.p.ation, or of exultation in race, or of rivalry, matters not; but one is inclined to the last theory, for none but males take part in it. The sun glints on their burnished b.r.e.a.s.t.s, their throats throb, their long bills quaver with enthusiastic effort, and the song still matters not, for it is but a thin twittering, so feeble and faint as to be inaudible a few yards off. Patience and stillness are the price of it.
