Part 9

Little is known of these birds in their natural state. "The Large-beaked Parrot," says von Rosenberg, "is not rare in the islands of Waigui, Misool, and Salawatti, and is found on the coast of New Guinea. It usually perches at the very top of the highest trees, keeping its body constantly in motion, and whilst resting, or when by powerful strokes of its wings it raises itself into the air, it utters a trumpet-like note quite different from that produced by the White Cockatoo. The natives take the young birds from the nest, and, when they have reared them, sell them to traders. In captivity they seem to prefer the fruit of the canary tree, the hard shell of which they manage to crack with the utmost facility. One of these so-called Cockatoos, belonging to a resident in Amboyna, was in the habit of flying about all over the town, but always returned home at the proper time to take its meals and to sleep." Von Marten saw a tame parrot of this kind at Mahai. "The Black Cockatoo," he observes, "when perched stiffly with its tail erect, red face, and powerful beak, has the air of an old general, and, owing to its extreme ugliness, makes a forcible impression on all who see it. It is quiet and slow in its movements, but allows strangers to approach, and utters from time to time a disagreeable, harsh, guttural shriek."

According to Rosenberg, the Large-beaked Parrot is often seen at Amboyna, where it may be bought for about twenty or twenty-five shillings: in Europe these remarkable birds are amongst the greatest curiosities in our collections. Unlike all other parrots with which we are acquainted, the Casmalos uses its peculiarly-formed tongue in a strange manner; taking its food with its foot, it carries the morsel to its beak, tears it up, and presses the end of the tongue, which is provided with a round horn-like plate, upon the pieces, which stick to it; the tongue is then drawn in, and the food swallowed; this being a very slow process, the meal usually occupies a considerable time.

* * * * *

The RAVEN COCKATOOS (_Calyptorhynchus_) differ very materially from all other species not only in the colour of the feathers, but in their form. The beak is short, crescent-shaped, and sloping, owing to the great breadth of the lower jaw; the wings are large and broad, reaching only over the first third of the long, strong, and rounded tail; the crest is comparatively small.

The Raven Cockatoos, or Geringeroes, are found exclusively in New Holland, and there only in certain districts. Gould, the great explorer of Australian ornithology, mentions six species in his masterly work, and gives a tolerably full account of their mode of life; there is, however, great similarity between them, and the following observations may be considered as applicable to all.

The Raven Cockatoos are truly _tree_-birds, feeding principally upon the seeds of the Eucalypti, and other trees indigenous to the country, but, unlike other parrots, they will occasionally eat large caterpillars. Another peculiarity is that they only congregate in small parties consisting of not more than from four to eight individuals, and never assemble in considerable flocks. Each part of Van Dieman's Land has its peculiar species.

The manner in which the Raven Cockatoos feed is also very peculiar. Some species break off the little twigs of the fruit trees while eating, apparently out of mischief; and all use their sharp beaks to draw the concealed living insects--principally larvæ--out of the wood. The large caterpillars which they obtain from the gum-trees do not always satisfy their hunger; they wage war upon the grubs that lurk deep in the wood, dextrously stripping off the bark and picking large holes in the branches until they reach their prey. Some species prefer insects to any other kind of nourishment, whilst others subsist upon seeds, principally those of the Casuarinæ and Banksias. Fruit they seem to despise, although they destroy much out of pure mischief, plucking it before it is ripe, to the great annoyance of the owners.

So far as we know, the Geringeroes breed exclusively in the holes of trees, always choosing the highest and most unapproachable trunks, and invariably such as the natives cannot climb. They prepare no regular nest in the holes which they select, or at most only collect chips of wood from the ground, wherewith to line the interior. They lay from two to five tolerably large eggs, 1 2/3 inch in length and 1 1/3 inch broad. Besides the attacks made upon them by man, the Raven Cockatoos often become victims to birds and beasts of prey. Europeans do not prize their flesh very highly, but by the natives it is esteemed a delicacy.

BANKS' RAVEN COCKATOO.

BANKS' RAVEN COCKATOO (_Calyptorhynchus Banksii_) attains the length of a foot and a half. The plumage of the male is black, the only exception being the tail, which is a brilliant black with a greenish sheen. The female is greenish-black upon the head, spotted with yellow on the neck and wings, and striped with light yellow upon the breast. The male has a broad scarlet band extending along the middle of the tail, but not reaching the two middle feathers or the outer edge of the side feathers. The female has broad yellow and reddish-yellow spotted stripes similarly disposed, both upon the outer and the under side of the tail-covers.

Banks' Raven Cockatoo belongs to New South Wales, and is principally found in the district between Moreton Bay and Port Philip, though by no means rare in the immediate neighbourhood of Sydney and other large towns. Its flight is heavy; the wings are lax, and seem to move with difficulty; it seldom rises high in the air, but will, nevertheless, sometimes fly for a mile at a stretch; whilst on the wing it utters a loud cry, which is less shrill than the harsh screech of the cockatoo. When on the ground, these birds move with difficulty; upon the tops of trees their motions are less deliberate, but always slow. Most of them are shy and distrustful, owing no doubt to the manifold persecutions from which they suffer, and it is only during feeding-time that they are less upon the watch. They are much attached to their companions, and should one of them be killed or wounded, the hapless individual is seldom deserted by the others, who generally fly about him, uttering a wailing cry, and expose themselves so recklessly to the hunter, that he, knowing how to avail himself of this habit, often succeeds in capturing the whole flock.

THE KAKAPO, OR NIGHT-PARROT OF NEW ZEALAND.

For the same reason that the Owls and the Falcons are grouped as distinct families, we shall consider the KAKAPO, or NIGHT-PARROT OF NEW ZEALAND (_Strigops habroptilus_) as the type of a peculiar race. This bird, indeed, reminds us so forcibly of the Owls, that were it not for the structure of the foot, we should decidedly class it as one of them. Its scientific name of "owl-faced" (_Strigops_) is very well chosen. The large body of this species is covered with soft, delicate feathers, which form a rudimentary veil about the face; the wings are short and trough-shaped; the tail long and rounded; the beak long, bent like that of an owl, and nearly covered with stiff, bristle-like feathers; the feet are of middle size, the toes long. The general colour is a dark green, interspersed with tolerably regular stripes, and some irregular yellow spots; upon the breast the colour is lighter and yellower than on the back, and the stripes are indistinct; the green tail is banded with dark brown. The habitat of the Kakapo is restricted to New Zealand, and the species is now found in tolerable abundance only in the most remote Alpine valleys of the southern island. It has been nearly exterminated in the northern portion. Lyall and Haast have given us full particulars of its habits. "The Kakapo," says the first of these writers, "is still found occasionally in the northern districts of New Zealand, frequenting the dry cliffs or the low grounds near the banks of the rivers, where the high trees and woods are, to some extent, free from ferns and brushwood. The first time we met with it was upon some hills, rising 4,000 feet above the level of the sea; but we afterwards found it living with others of the same species, on open spots near the mouth of the river, and not far from the coast." "Most striking," adds Haast, "is the fact that the Kakapo (except in the valley of the Makavora, formed by the Lake Wanaka) is never seen east of the mountains, although forests abound there; apparently the absence of woodland in the intervening district is an obstacle to its farther progress in that direction. These birds are less numerous in the Wilkin valley, where I have observed traces of the wild dog; in the valley of the Hunter, which is only separated from these districts by a chain of not very high mountains and some inconsiderable hills, no trace of them is to be found, although the fine beech forests offer them a favourable retreat." "In such places," says Lyall, "the tracks of the Kakapo were visible; these are about a foot wide, very regularly worn, and often resemble in so striking a manner those made by men, that at first we really believed that the natives must have been in the neighbourhood. The Kakapo lives in holes under the roots of trees, and in the cavities of overhanging rocks."

Lyall tells us that the holes he saw had two openings, and the trees above them were for some distance hollow. The Kakapo, he says, was not visible by day, except when driven from its retreat; and he was never able to find it but with the help of dogs. When these birds were more plentiful, the natives used to catch them at night by torch-light. There is a breed of half-wild dogs in the northern part of this island continually hunting the Kakapos, which, indeed, they have almost exterminated. It is said that the spread of these dogs is arrested by a river; but it is to be feared that so soon as they succeed in crossing that barrier, the total extinction of these birds will ensue; for although they use their beak and claws very energetically, and can make a powerful resistance, still, sooner or later, they must succumb to their four-footed enemy, and ultimately share the fate of the MOA, the DRONTE, and other species recently become extinct. "The Maoris assure me," says Haast, "that the Kakapo is brave, and often confronts the dogs with success; but this cannot be credited if their dogs are worth anything, for mine never had any serious battle with it. At first, the dog was attacked both with beak and claws, but it soon learnt to conquer its game by biting it through the back." An idea was formerly entertained that the Kakapos were nocturnal in their habits, but our observations lead us to believe that this is not exactly the case. We generally heard their voices about an hour after sunset, in places which were rendered dark and obscured by thick foliage, and they then began to sweep about, attracted by the light. We, however, twice saw these birds during the day feeding upon the ground, and strictly upon their guard against approaching danger. On the first occasion, about noon on a cloudy day, we were returning through an open wood from the western coast, and saw the Kakapo sitting upon an uprooted tree, not far from the Haast river; as we approached, it quickly disappeared, but was caught by the dogs. The second time, on a clear day, as we entered a deep ravine, we saw one of these birds perched ten feet high upon a fuchsia-tree, the berries of which it was eating. As soon as it saw us, it fell, as though shot, to the earth, and disappeared beneath the surrounding blocks of stone. The most astonishing thing was, that the bird made no use of its wings; indeed, did not even open them to break its fall. In order to ascertain whether it would either fly or flutter, we followed, and having with us a Kakapo that had been taken uninjured by the dogs, we set it free upon a large, open, gravelly spot, where there was plenty of room to run away, if it wished to do so, or to raise itself into the air, even should it require a large space for that purpose. We were much surprised to find that it only ran to the nearest thicket, and that much faster than we could have thought possible from the structure of its toes and the bulk of its body. Its movements resembled those of a barn-door fowl. We stood on one side of it, and it appeared to us that it kept its wings quite close to the body; but one of our companions, who was behind it, observed that the wings were slightly raised, but motionless; so that doubtless they are employed more as a means of balancing the bird than to accelerate its progress. Though its shape is not suited to running, it can progress in this manner to a considerable distance, as we often saw by its tracks, which extended sometimes for more than a mile over sand and shingle down to the bank of the river. Lyall, however, has seen this bird flying, though only for trifling distances. "During our hunt," he says, "we only saw the Kakapo fly when, having climbed a hollow tree, it wished to reach another in the neighbourhood. From the first tree it flew down to the next in height, making its way up each in turn, climbing very quickly to the top by the help of its tail; the motion of the wings was very trifling--indeed, almost imperceptible.

"The cry of the Kakapo is a hoarse croak, which changes into a discordant screech when the bird is angry or hungry. The Maoris declare that the noise these creatures make is sometimes deafening during the winter, when they congregate in great numbers, and greet each other on their arrival or departure. The stomach of a specimen we killed contained a pale or almost white homogeneous mass, without any trace of flesh, so that, doubtless, its food consists partly of roots and partly of leaves and delicate shoots of plants. We observed that at one place where the birds were very numerous, a leguminous plant, growing on the banks of the river, had all its buds nipped off; and learnt from a boatman, who had lived in that place for many years engaged in the whale fisheries, that the Kakapo was the offender. We also found its beak covered with hardened dirt. This species, he told us, requires a great deal of river water in order to dilute the pulpy mass of vegetable matter in its crop. Except in two instances, in which berries had been eaten, we found the crop always filled with half-digested moss, and so distended and heavy that it weighed many ounces; the bird, moreover, appeared much smaller when the crop was emptied. The quantity of innutritious food with which it stuffs itself explains its liking for living upon the ground, and compels it to resort to wild localities inhabited by no other parrots. Another peculiarity, also perhaps a consequence of this vegetable diet, is, that instead of the soft oily fat that other birds have under the skin, it has an abundance of solid white fat; its flesh is much whiter than that of other parrots, and has a very superior flavour. We must be forgiven for observing that it is a dainty article of food for those who are wandering in these wildernesses, and we can quite believe that the Maoris smack their lips whenever the Kakapo is mentioned."

On the subject of their propagation, Lyall makes the following statement:--"During the latter half of February and the first days of March, at which time we tarried among the dwelling-places of the Kakapos, I found young in many holes, often only one, and never more than two in each. In one instance I found a single nestling and an addled egg. Sometimes, not always, I found the parent in the hole. There is no real nest; the bird only scratches a shallow cavity in the dry mass of decayed wood. The egg is pure white, about the size of a pigeon's.

"Many young birds were brought to us on board ship, but most of them died in a few days, apparently in consequence of the unusual treatment; others lived for some months. Generally, after a few weeks, their legs were crippled by confinement, either on account of the smallness of their cage, or the want of proper food. We fed them principally with sopped bread and cooked potatoes; if we allowed them to run about in the garden, they ate the grass and cabbages, and snapped eagerly at every green leaf that came in their way. A Kakapo which we succeeded in bringing alive to within six hundred miles of the English coast, ate, while we resided in Sydney, the leaves of the Banksias and Eucalypti. It seemed to relish nuts and almonds, and during the latter part of our voyage home, lived almost entirely upon Brazil nuts. On several occasions this bird was seized with cramp for two or three days, and whilst this lasted it ate nothing, cried furiously, and hacked with its bill if any one ventured to disturb it. At such times it was not to be trusted, for it bit most fiercely, precisely when least expected. Its temper was always at the best when any one took it out of its cage. Early in the morning it would busy itself, as soon as out of confinement, with the first object that came in its way, generally with our trousers or boots. The latter it much fancied--it would squat upon them, beat its wings, and give every symptom of the greatest enjoyment; it would then rise, rub its sides against them, roll on them back downwards, and kick its feet in the most lively manner. An unlucky accident caused its death."

Another of these birds, which Captain Stoke brought ashore and transmitted to the care of Major Murray, was allowed to run about the garden freely. It showed a strong liking for the company of children, and would follow them about like a dog.

* * * * *

The LONG-TAILED PARROTS are rich in species, and present considerable variety in their dimensions, their size ranging from that of the largest Parrot to that of a Finch; but they all possess in common a graduated tail, at least as long as the body, the middle feathers of which are sometimes twice the length of those at the side. The wings, which are moderately pointed, seldom reach, when folded, beyond the first third of the tail. The beak is, as a rule, strong, almost always short, and very round, but sometimes, in solitary cases, it is long and but slightly bowed.

The plumage of the Long-tailed Parrots is very varied, still it never possesses the softness and gloss observable in the coat of the Lory. A tuft-like prolongation of the feathers is rarely but occasionally met with. It is, however, impossible to describe the plumage of this group in general terms; suffice it to say, that the hues we have mentioned as employed in the coloration of other parrots, also predominate in their feathers. The Long-tailed Parrots may be considered as the type of their order, inhabiting, as they do, all the various countries in which the race is found.

THE ARARAS.

Amongst the Long-tailed Parrots, the ARARAS (_Aræ_) are easily distinguished by their unusually large beak, furnished with a smooth broad summit. The lower mandible is very short, and incised or obliquely cut, without any ridge upon the chin, and having its base entirely covered by a cere. The cheeks are broad and naked, but sometimes covered with small feathers arranged in rows; the tarsus is thick, strong, and short; the toes long, and furnished with large strongly bent claws; the wings are long and pointed, and reach far down the tail, which is longer than the body. The plumage is very thick.

The members of this very conspicuous group are almost exclusively confined to the eastern parts of South America, where they inhabit the primitive forests, far from man and the turmoil of the world. Unlike other parrots, they live in little companies, which very rarely unite to form a flock. They feed principally upon fruit, are comparatively quiet, and although they exhibit but little vivacity, are as intelligent as the rest of their race.

THE SCARLET MACAW (_Ara Macao_).

This species is about 2 3/4 feet long, of which more than 1 foot belongs to the tail; the stretch of its wings is about 3 3/4 feet. The plumage is magnificent and very brightly coloured. The head, neck, breast, and belly are scarlet; the feathers of the neck and upper part of the back have a greenish edge, which becomes broader lower down. The middle and lower regions of the back, the rump, and under tail-covers are a beautiful sky blue; the upper feathers of the wings are scarlet; the middle, hinder, under, and shoulder feathers green, the latter shaded with red; the front wing-covers are ultramarine on the outer web, and on the inner pale red. The same is the case with the inner wing-covers; the middle tail-feathers are more or less red, the inner web of the quills black. On the naked flesh-coloured cheeks, which look as though powdered with white flour, are five or six rows of little pencil-shaped red feathers, implanted near the nostrils, and ranged around the eyes; the beak is of a clear horn colour, black at the point and edge, as is the lower mandible; the eyes are yellowish white, the feet blackish grey, the claws brownish black. The two sexes are alike in colour, the young birds more delicately tinted than the old ones. In the variety of this bird represented in the frontispiece to Part I., the colours are somewhat different.

The principal portion of the plumage is bright scarlet, the quill-feathers of the wings fine blue, the greater wing-coverts yellow, tinged with green, the upper and under tail-coverts blue, the two middle feathers of the tail crimson, and the remainder of the tail-feathers, which gradually decrease in length towards the sides, are partly red and partly blue; the feet are dusky black, the naked skin of the cheeks wrinkled and white, the upper mandible whitish, and the lower one black or dusky.

The Macaw was formerly to be found in the immediate neighbourhood of such large cities as Rio de Janeiro, &c., but it has long since left the inhabited part of the country. Flat, well-watered, primitive forests appear to be its favourite haunts; it will not ascend mountains, but in high, parched districts, burnt up by the heat of the sun, or in the rocky, wild parts of Bahia, its cry is constantly to be heard. "Whilst we were upon the rivers that irrigate the woods upon the coast," says the Prince von Wied, "we saw this proud red bird, and recognised it at once by its voice, size, and streaming tail, as it slowly beat the air with its long large wings, and steered its course through the blue air." "The habits of this beautiful bird," continues the same author, "resemble those of other parrots. At noon we generally saw them sitting quietly upon the strong under-branches of a large tree, the neck drawn in, and the long tail hanging straight down. Except during pairing time, they fly in small companies in search of different kinds of fruits, especially those of various species of palms, on the hard shells of which they are very fond of trying their powerful beaks. Notwithstanding the noise they usually make, like other species of parrots they become at once perfectly silent so soon as they have found a tree laden with suitable produce, and when they settle upon it, their presence is only indicated by the fall of the husks, which they bite off and throw down. During the cold season of the year we often found them busily seeking out the fruit of a creeping plant called _sphinha_; they climb up its tangled stems very adroitly, and it is then easier to shoot them than under other circumstances. Their crops were quite full of the white seeds of this plant; at other times we found their beaks dyed blue by some species of fruit that they had eaten."
