ancients, who attributed a fabulous power of fascination to the bird so that as it flew over the ponds the fish "turned their glistering bellies up" that it might take liberal choice. Certainly some limitation on the part of the fish seems to operate in favour of the osprey, otherwise the clumsy fisher would oft go hungry.

It goes against the grain to speak slightingly of the knightly, white-headed sea-eagle--a friend and almost a companion; but as any one may see that it fishes not for the sport but for the pot, and that the plunge into the water is a shock that is dreaded, no injustice is done. Some birds--and they the most graceful--seem to fish for sport alone. These three fishers fish because, like Kipling's kangaroo, they have to--only the kangaroo hopped.

Now, the white-headed sea-eagle, which seems, and with good reason, to be proud of its ruddy back, appears to have no enemy of its kind. While the osprey and the white-bellied sea-eagle fall out and chide and fight, it looks down from some superior height and placidly watches the fish trap, for though knightly it is not above accepting tribute, for it likes fish though it hates fishing.

The great osprey seldom crosses the bay without a challenge from its stealthy foe, the white-belly. The voices of both are alike in their dissonance though different in quality and tone, and the smaller bird is invariably the aggressor. This is how they fight, or rather engage in a vulgar brawl which has in it a smack of tragedy. The osprey, with steady beat of outstretched wing, flies "squaking" from its agile enemy, who endeavours to alight on the osprey's back. Just as white-belly stretches its talons for a grip among the osprey's feathers, the osprey turns--and turns without a tremor in its long, sweeping wings--to shake hands with white-belly. For a moment the huge bird rests on its back, silhouetted against the luminous sky, to interlock talons with its nimble foe. But white-belly is fully alive to the risk of getting "into hoults" with so heavy a weight, for on the instant it swoops up with a harsh cry of rage or disappointment. With but a single flap and no quiver of wing the osprey rights itself and sails away (a methodic, unflurried flight) with fleeter white-belly in pursuit, which when within striking distance swoops again, to be faced by the grim, outstretched talons of the osprey, who has turned in flight with machine-like precision. So swift and sudden is the discreet upward swoop of the white-belly that it almost appears to be a rebound after contact with the bigger bird. So the scrimmage, or, to be exact, screamage, proceeds, for each party to it tells the whole Island of its valour, and business stands still as the series of most graceful, yet savage, aerial evolutions is repeated until the rivals are blotted out by distance.

Once I saw a bunch of feathers fly from the osprey's back. The aerial capsize had not been timed with accustomed accuracy. Weight told, and it speedily shook itself free; but I am waiting for the day when, in mid-air, the osprey and the white-bellied sea-eagle shall clasp hands. It will be an exciting moment for the sea-eagle. The osprey is a cuter as well as a heavier bird, and, in the phrase of the blacks, "That fella carn let go!"

When the osprey comes skirting the hollows of the hills for cockatoos, its hunger will be unsatisfied until, by elaborate and disdainful manoeuvres, the cockatoos are induced to take flight. Perched on the top of a tree, they may jeer in safety as long as they like; but let the flock fly into the open and the osprey will be surprised if it does not get one, and that which is singled out it follows "like a grim murderer still steady to his purpose." Now is the time for this, greatest of the three fishers, to, wax fat and become pompous, for its diet is to be varied with nutmeg pigeons, and the pigeons have come in their thousands and tens of thousands, and if the eaglets do lack and suffer hunger, it will be on account of the laziness of their parents.

For all its laborious fishing, the red-backed sea-eagle is sometimes deprived of its spoil by a bird much inferior in size and weight and which has not the slightest pretensions to the art. An eagle had captured a "mainsail" fish (banded dory) which loomed black against its snowy breast as in strenuous spirals it sought to gain sufficient height whence to soar over the spur of the hill to its eyrie. The fish, though not weighty, was awkward to carry, and the presence of the boat rather baffled the bird, which was shadowed in envious though discreet flight by a white-bellied eagle. Low over the water, close to the fringe of jungle the eagle flew, when a grey falcon dashed out, snatched from its talons the wriggling fish, and with one swoop disappeared under a yellow-flowered hibiscus bush overhanging the tideway. The falcon is no match for the eagle; but, most subtle of birds of prey, it had watched the perplexity of its lord and master, and with audacious courage taken advantage of a moment's embarrassment.


CHAPTER XXI



SOCIALISTIC BIRDS

Repeated observations and diary records have established August 12th as the beginning of the local "bird season." About that date two of the most notable birds arrive from the North--the nutmeg pigeon (MYRISTICIVORA SPILORRHOA) and the metallic starling (CALORNIS METALLICA). Having spent five months in Papua, Java, Borneo, and the Malay Peninsula, the former revisit the islands for incubating purposes.

Where the metallic starlings spend their retreat I know not; but they return with impetuous haste, as if absence had been disciplinary and not for pleasure. They assemble in glittering throngs, shrilly discussing their plans for the season, without reserve debating important concerns of house and home. Shall the tall Moreton Bay ash in the forest be again occupied and the shabby remnants of old nests designedly destroyed before departure last season be renovated, or shall a new settlement be established and the massive milkwood-tree overtopping the jungle be selected as a capital site? Discussion is acidulous and constant. For days the majority of the burnished citizens do little else but talk, while the industrious few begin, some to build nests on the sites of the old, others to lay hasty foundations among the leaves of the milkwood. Each faction wishes to carry its point, for ever and anon both rejoin the main body and proclaim and testify. Then all adjourn to the disputed sites successively and join in frantic commotion until some sage makes an entirely original proposition, and off they all go on a flight of inspection and abruptly end all differences of opinion by favouring a tree which appears to have no distinctive merits.

These delightfully engaging birds have been known to nest in a particular tree for a quarter of a century, and again they may select a different site every year. Though I have no evidence in confirmation of the theory, I am inclined to think that arboreal snakes are influential in causing changes. Although the domed nests must be difficult for even a snake to enter so large a congregation of noisy birds would inevitably attract these slim nocturnal marauders.

Moreover, a case may be cited in support of the theory. In a Moreton Bay ash (EUCALYPTUS TESSELARIS), not far from this spot, there nested a pair of white-headed sea eagles, a pair of cockatoos, and a colony of metallic starlings, four or five hundred strong. The memory of man knows not the first settlement of this amicable community, which remained until during temporary absence the blacks were suborned to climb the tree to secure the eggs of the eagle. They also helped themselves to a few of the callow starlings. The sea eagles and cockatoos discarded the tree forthwith, and the starlings in a couple of years. And why? Because, in my opinion at least, the eagles had policed the tree, killing offhand any green or grey snake which had the stupidity to sneak among the nests. When the policemen went to another beat the snakes took to frightening the unprotected birds and to the burgling of their nest. This incident caused a revision of the protective laws. They are much more explicit, and the pains and penalties for the violation of them are now absolutely unholy in their truculence.

During the 1909 season a serious diminution was noted in the number of metallic starlings and nutmeg pigeons. In the case of the former I am at a loss to account for the cause of the comparatively few visitors--always highly esteemed and admired and preserved from interference--except on the theory of the outbreak of an epidemic or in the possible fact that they are falling victims to the feminine passion for fine feathers.

The Grouse Disease Commission has found a recognised period in the fluctuations of the number of those game birds. During a cycle of sixty years there recur the good year, the very good year, the record year, the bad disease year, the recovery, the average, and the good average. The round is said to be almost invariable. So may it be with the metallic starling.

With the nutmeg pigeons the case is different. Here we have direct evidence of the desolating effects of the interference of man. Congregating in large numbers on the islands to nest, and only to nest, these birds offer quite charming sport to men with guns. They are the easiest of all shooting. Big and white, and given to grouping themselves in cloudy patches on favourable trees, I have heard of a black boy, with a rusty gun, powder, and small stones for shot, filling a flour-sack full during an afternoon. It is, therefore, not strange that men shoot 250 in an hour or so. The strange thing is that "men" boast of such butchery. On the very island where this bag Of 250 was obtained a little black boy, twelve years old, killed four pigeons with a single sweep of a long stick. He did not boast--to his father and mother and himself the four birds represented supper; but in the case of the sportsman it might be asked, how many of the butchered doves went into the all-redeeming pot?

These pigeons are one of the natural features of the coast of North Queensland, in the conservation of which the State and the Commonwealth are concerned. It may be contended that the extermination of a species represented by such multitudes is impossible. But while the history of the passenger pigeon of North America is extant such argument carries no weight.

When the birds are, so to speak, shot on their nests or sitting in their crowded dormitories a whole season's natural increase may be discounted by an afternoon's wretched "sport." If nutmeg pigeons are to be preserved as one of the attractions and natural features of the coast of North Queensland, extensive sanctuaries must be established. Strict prohibition might be enforced for a period of, say, five years to enable the colonies to regain their population, and thenceforward they might--if the shooting of sitting birds is still deemed to be "sport"--be allowed a "jubilee" every second year.

If the unrestricted molestation is permitted, the day is not far distant when indignation will arise and lovers of Nature will ask passionately why a unique feature of the coast was allowed to be obliterated in blood. True sportsmen would unanimously rejoice in the permanent preservation of birds elegant and swift of flight, not very good to eat, and which visit us at a time when inhospitality is a wanton crime.
