THE CRESTED HAWK PARROT (Deroptyus accipitrinus coronatus).
THE SPARROW PARROT.
The Sparrow Parrot (Psittacula passerina) is one of the smallest of the Brazilian parrots, being scarcely or not at all larger than the species we have just described. The colour of the plumage is a bright green, shaded into yellow upon the brow, face, and lower parts. The under-side of the tail and tail-covers are of a pale bright bluish green; the anterior border of the wing, the large wing-covers, the back, and secondary quill-feathers, as well as the inner wing-covers and the under part of the body, are of a bright ultramarine; the primary quills are blackish brown, with a green anterior edge. The beak is a bluish ashy green; the cere somewhat darker; the feet ash grey, with green, scale-like plates; the eyes brown.
The Sparrow Parrot is very common in Brazil, and inhabits both the woodlands near the sea-coast and the bushes in dry districts, to which it is an admirable ornament. These birds come in troops into the gardens of the settlers like our sparrows, which they also resemble in the fact that when in company with others of their kind they scream and chatter in a very confused manner, the united flock producing a shrill twittering sound. They settle in great numbers upon a tree or shrub to nibble the fruit, during which time the whole swarm is in unceasing confusion, climbing nimbly up and down the branches, and whistling briskly. In other respects the Sparrow Parrot lives after the same manner as the rest of its relatives, making the same kind of nest, sometimes using the deserted oven-shaped abode of the Crested Parrot, and laying from three to four white eggs upon the shreds of wood that cover the bottom of the hole. Both young and old are often captured by the Brazilians, and seem soon to forget the loss of their freedom, if they are not separated from their mates. They are but short lived, and for that reason seldom reach Europe; still, it occasionally happens that, with great care, they will survive some years, and even breed in a state of captivity.
THE SISKIN PARROT.
The Siskin Parrot (Nasiterna pygmæa), the dwarf among the dwarfs belonging to this order, lives in New Guinea and the Papuan Islands. Its green plumage is varied by a yellowish shade on the head, and the face is light golden brown; the middle tail-feathers are blue, the rest are black, with yellow tips; the beak is extraordinarily high and strong. As far as we know, this bird is not rare upon the high trees on the coast of New Guinea and in the forests of Salawatis and Misool, but no observer has as yet given us particulars of its habits.
COCKATOOS.
Amongst the different species of parrots with which Australia is enriched the Cockatoos (Plyctolophus) take high rank. The members of this group are distinguished by their compact body, short tail, and wings of middle size; their large, short, broad beak toothed at the margin, the upper mandible of which terminates in a strong hook. The tongue is usually fleshy and smooth, the region of the eye bare, and the head decked with an upright tuft of bright and beautiful feathers. The plumage is generally very striking, either by reason of its pure white or delicate rose colour, or (for a parrot) the unusually dark tints that predominate. Cockatoos are found not only in Australia, but in the Moluccas, New Guinea, and the Philippine Islands, where most kinds establish themselves in enormous flocks in the woods, and fly from thence over the fields and plains, presenting an appearance that is enchantingly beautiful. "Perched under the shadow of the dark foliage," says Mitchell, "their bright wings and glowing crests transform the heights upon which they live into regions of the most exquisite beauty." In their habits and mode of life Cockatoos resemble other parrots, and must be reckoned among the most pleasing of the whole race. It is quite true that when living together in large flocks their cries frequently become a deafening noise intolerable to ordinary ears, but a solitary bird is very engaging; indeed, there is something so extremely tender in the tone in which it utters the word "cockatoo" (whence is derived the name), that it attracts us involuntarily, for the cry of "cockatoo" is always intended to express a kindly feeling, and changes when angry into a most fearful shriek. The Cockatoo soon learns to make friends with mankind, plays fewer tricks than other parrots, appears grateful for any kindness that is shown to it, and seems eager to make a fitting return; unkindness alone makes it ill-tempered or mischievous, and its excellent memory enables it to avenge an injury after the lapse of years. Its disposition in general is mild and gentle, and its good qualities numerous. It learns to speak with tolerable ease and fluency, forming the words into phrases, as though it understood them, and applies whole sentences at a fitting opportunity. In their wild state, Cockatoos assemble in large flocks, which remain more or less united even during the breeding season; they pass the night buried in the leafy shelter of the trees, and at break of day make the woods resound with their noisy screams as they rise into the air with light strokes of the wing, hovering and gliding till they reach a field yielding suitable food. Fruit, corn, and seeds constitute their principal nourishment, and they will also devour buds and bulbs, obtaining the latter very dextrously by the help of their long beaks. Every fresh occurrence in their daily life is greeted with loud cries; and should a second flock pass over the place where they have settled, their combined shrieks are perfectly appalling, and can only be imagined by those who have heard the yells a few captive cockatoos are capable of producing. As soon as hunger is appeased these flocks retire to rest beneath the shelter of the branches, where they remain some hours in comparative quiet; they then again go in search of a meal, returning to pass the night on their accustomed trees. Thus they live till the breeding season, when they pair, and each couple sets out to find a suitable home, preferring holes in trees, but also resorting to fissures in the rocks. Certain precipices near the South Australian rivers are yearly visited by thousands of Cockatoos, just as the cliffs of the north seas are infested by huge flocks of sea-gulls. We are told that some of these rocks are completely honeycombed by them, and the strength and firmness of their beaks renders this assertion easily credible. They lay two white, pointed eggs, about the size of those of a bantam fowl; but in what manner incubation is carried on we are not aware. We are told by travellers that they soon become timid if they suspect danger, and, like other kinds of parrots, carry on their depredations with so much cunning that it is very difficult, or indeed impossible, to drive them from the fields. The natives hunt them in a very peculiar manner. "Perhaps," says Captain Grey, "it would be impossible to imagine a more exciting spectacle than that of seeing the Australians hunt the Cockatoo. They employ for this purpose a very remarkable weapon called a boomerang; this is a sickle-shaped flat instrument made of wood, which can be thrown by the hand to a distance of 100 feet, and flies in small circles with many windings from the direct path. An Australian will follow a flock either into the fields or woods, preferring, however, places where large trees are situated near water, such spots as these being the favourite resort of the Cockatoos. Here they are to be found in innumerable hosts, climbing on the branches or flying from tree to tree; here they also sleep, and here the wily native comes, most watchfully observing all necessary precautions. He goes from one tree to another, and creeps from bush to bush, taking the greatest care not to disturb the wary birds, but in vain, for, however quiet his movements may be, he is soon discovered, and his near approach greeted with a hideous cry. The birds have already perceived that danger is at hand, though they do not know what the next step may be. At length their pursuer reaches the water, and discloses his dark form to their view; amidst piercing shrieks the white cloud of birds rises into the air, and at the same instant the Australian throws his weapon amongst them. The boomerang, which is thrown with great force, dances and springs in the most wonderful manner over the water, and then, rising higher and higher in its wayward flight, is soon careering in the midst of the frightened multitude. A second, a third, and a fourth weapon is discharged; in vain the terrified creatures try to escape, the apparently aimless course of the missile bewilders them and delays their flight. One after the other is struck by the boomerang, and comes to the ground, having probably either lost its head or broken its wing; they fall screaming with pain and terror, and it is only when the dusky hunter has attained his end that the remainder of the terrified flock hide themselves in the foliage of the trees." The flesh of the Cockatoo is tolerably good, and the soup made from it excellent. The number of these birds that find a home with us prove that they are easily captured, and, like all other parrots, they will live a long time if nourished with simple food.
