My Tropic Isle

by E. J. Banfield

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.

For this indulgence of my feelings I have, I am aware, laid myself open to censure. It is foreign to, indeed, quite out of place in, a book which professes neither message nor mission. Yet, mayhap, some kindred spirit having influence and judicious eloquence at command may read these lines. Then the birds need not much longer fear the naughty local man. Long may the dulcet islands within the Barrier Reef burst morn and eve into snowy bloom as the pigeons go and come!

So having soothed my fretfulness by irresponsible scolding, consigned countless white pigeons to inviolable sanctuary and thereby confirmed to perpetuity the charter under which a bustling interchange of seeds and the kernels of fruit-trees between isle and mainland is maintained, I am at liberty to chronicle certain every-day incidents in the establishment of a colony by those other companionable birds, metallic starlings, also under engagement to Nature as distributing agents.
