or five islands--miles apart--to rest and breed. The assemblages 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 cockatoos, scrub turkeys, and scrub fowls scattered over an area of the mainland corresponding in extent with the feeding-ground of the nutmeg pigeons were massed 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 association, 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 pass 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 deglutition 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 assimilated. 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 assemblage occurs only in the tragic presence of a falcon, whose murderous deeds are transiently recorded by stray painted feathers. But the fright soon passes, 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 bass. "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 assurance 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 passing 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.

Cockatoos 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-assertive 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 passed 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
