Part 17

Professor Owen, in his minute examination of the mandibles, remarks that the principle of the cylinder is introduced into the elaborate structure; the smallest of the supporting pillars of the mandibles are seen to be hollow or tubular when examined with the microscope.

Light and almost diaphonous as is the bill of the Toucan, its strength and the power of the muscles, which act upon the mandibles, are evident in the wrenching and masticatory processes. When taking fruit, the Toucan generally holds it for a short time at the extremity of his bill, applying to it, with apparent delight, the pointed tip of the slender tongue: the bird then throws it, with a sudden upward jerk, to the throat, where it is caught and instantly swallowed.

Mr. Gould divides the Toucans into six genera. 1. The true Toucans, with large and gaily-coloured bills, plumage black. 2. The Araçaris, with smaller beaks, plumage green, yellow, and red. 3. The Banded Aracauris, an Amazonian genus, proposed by Prince C. L. Bonaparte. 4. Toucanets, small, with crescent of yellow on the back, and brilliant orange and yellow ear-coverts. 5. Hill Toucans of the Andes. 6. Groove-bills, grass-green plumage.

A very fine true Toucan, figured by Mr. Gould, is remarkable for the splendour and size of the bill, of a fine orange-red, with a large black patch on each side. Powder-flasks are made of large and finely-coloured bills. The naked skin round the eye is bright orange. The chest is white, with a tinge of sulphur below, and a slight scarlet margin. Upper tail-coverts, white; under tail-coverts, scarlet; the rest of the plumage, black. Several specimens of this beautiful bird lived both in the menagerie of the late Earl of Derby, at Knowsley, and in the gardens of the Zoological Society. It is a native of Cayenne, Paraguay, &c.

Toucans in their manners are gentle and confident, exhibiting no alarm at strangers, and are as playful as magpies or jackdaws; travellers assure us that they may be taught tricks and feats like parrots; and although they cannot imitate the human voice, they show considerable intelligence. One of the Toucanets is named from Mr. Gould, the plates in whose monograph, from their size, beauty, and accuracy, have all the air of portraits.

ECCENTRICITIES OF PENGUINS.

This group of amphibious birds, though powerless in the wing as an organ of flight, are assisted by it as a species of fin in their rapid divings and evolutions under water, and even as a kind of anterior of extremity when progressing on the land. Their lot has been wisely cast on those desolate southern islands and shores where man rarely intrudes, and in many instances where a churlish climate or a barren soil offers no temptations to him to invade their territory.

Le Vaillant, when on Dassen Island, found that the smaller crevices of the rocks served as places of retreat for Penguins, which swarmed there. "This bird," says Le Vaillant, which is about two feet in length, "does not carry its body in the same manner as others: it stands perpendicularly on its two feet, which gives it an air of gravity, so much the more ridiculous as its wings, which have no feathers, hang carelessly down on each side; it never uses them but in swimming. As we advanced towards the middle of the island we met innumerable troops of them. Standing firm and erect on their legs, these animals never deranged themselves in the least to let us pass; they more particularly surrounded the mausoleum, and seemed as if determined to prevent us from approaching it. All the environs were entirely beset with them. Nature had done more for the plain tomb of the poor Danish captain than what proceeds from the imaginations of poets or the chisels of our artists. The hideous owl, however well sculptured in our churches, has not half so dead and melancholy an air as the Penguin. The mournful cries of this animal, mixed with those of the sea-calf, impressed on my mind a kind of gloom which much disposed me to tender sensations of sadness. My eyes were sometime fixed on the last abode of the unfortunate traveller, and I gave his manes the tribute of a sigh."

Sir John Narborough says of the Patagonian Penguins that their erect attitude and bluish-black backs, contrasted with their white bellies, might cause them to be taken at a distance for young children with white pinafores on. A line of them is engraved in Webster's "Voyage of the Chanticleer," and reminds us of one of the woodcuts in Hood's "Comic Annual."

The "towns, camps, and rookeries," as they have been called, of Penguins have been often described. At the Falkland Islands are assemblies of Penguins, which give a dreary desolation to the place, in the utter absence of the human race. In some of the towns voyagers describe a general stillness, and when the intruders walked among the feathered population to provide themselves with eggs, they were regarded with side-long glances, but they seemed to carry no terror with them. In many places the shores are covered with these birds, and three hundred have been taken within an hour; for they generally make no effort to escape, but stand quietly by whilst their companions are knocked down with sticks, till it comes to their turn.

The rookeries are described as designed with the utmost order and regularity, though they are the resort of several different species. A regular camp, often covering three or four acres, is laid out and levelled, and the ground disposed in squares for the nests, as accurately as if a surveyor had been employed. Their marchings and countermarchings are said to remind the observer of the manoeuvres of soldiers on parade. In the midst of this apparent order there appears to be not very good government, for the stronger species steal the eggs of the weaker if they are left unguarded; and the King Penguin is the greatest thief of all. Three species are found in the Falkland Islands. Two, the Kings and the Macaroni, deposit their eggs in these rookeries. The Jackass, which is the third, obtained its English name from its brayings at night. It makes its nests in burrows on downs and sandy plains; and Forster describes the ground as everywhere so much bored, that a person, in walking, often sinks up to the knees; and if the Penguin chance to be in her hole, she revenges herself on the passenger by fastening on his legs, which she bites very hard.

But these rookeries are insignificant when compared with a settlement of King Penguins, which Mr. G. Bennett saw at the north end of Macquarrie Island, in the South Pacific Ocean--a colony of these birds, which covered some thirty or forty acres. Here, during the whole of the day and night, 30,000 or 40,000 Penguins are continually landing, and an equal number going to sea. They are ranged, when on shore, in as regular ranks as a regiment of soldiers, and are classed, the young birds in one situation, the moulting birds in another, the sitting hens in a third, the clean birds in a fourth, &c.; and so strictly do birds in a similar condition congregate, that, should a moulting bird intrude itself among those which are clean, it is immediately ejected from them. The females, if approached during incubation, move away, carrying their eggs with them. At this time the male bird goes to sea, and collects food for the female, which becomes very fat.

Captain Fitzroy describes, at Noir Island, multitudes of Penguins swarming among the bushes and tussac-grass near the shore, for moulting and rearing their young. They were very valiant in self-defence, and ran open-mouthed by dozens at any one who invaded their territory. The manner of feeding their young is amusing. The old bird gets on a little eminence and makes a loud noise, between quacking and braying, holding its head up as if haranguing the Penguinnery, the young one standing close to it, but a little lower. The old bird then puts down its head, and opens its mouth widely, into which the young one thrusts its head, and then appears to suck from the throat of its mother; after which the clatter is repeated, and the young one is again fed: this continues for about ten minutes.

Mr. Darwin, having placed himself between a Penguin, on the Falkland Islands, and the water, was much amused by watching its habits. "It was a brown bird," says Mr. Darwin, "and, till reaching the sea, it regularly fought and drove me backwards. Nothing less than heavy blows would have stopped him: every inch gained, he firmly kept standing close before me, erect and determined. When thus opposed, he continually rolled his head from side to side in a very odd manner. While at sea, and undisturbed, this bird's note is very deep and solemn, and is often heard in the night time. In diving, its little plumeless wings are used as fins, but on the land as front legs. When crawling (it may be said on four legs) through the tussacks, or on the side of a grassy cliff, it moved so very quickly that it might readily have been mistaken for a quadruped. When at sea, and fishing, it comes to the surface for the purpose of breathing with such a spring, and dives again so instantaneously, that I defy any one, at first sight, to be sure that it is not a fish leaping for sport."

Bougainville endeavoured to bring home a Penguin alive. It became so tame that it followed the person who fed it; it ate bread, flesh, or fish; but it fell away and died. The four-footed Duck of Gesner might have owed its origin to an ill-preserved Penguin. The notion of its being four-footed might have been fortified by some voyager who had seen the bird making progress as Mr. Darwin has above described.

Mr. Webster describes the feathers of Penguins as very different from those of other birds, being short, very rigid, and the roots deeply embedded in fat. They are, in general, flat, and bent backwards, those on the breast being of a satin or silky white, and those on the flippers so short and small as to approach the nature of scales, overlaying each other very closely. The skins are loaded with fat. Their feet are not regularly webbed, but present a broad, fleshy surface, more adapted for walking than swimming. Mr. Webster saw great numbers of Penguins on Staten Island. They are the only genus of the feathered race that are there, and live in the water, like seals. He saw them at the distance of 200 miles from the land, swimming with the rapidity of the dolphin, the swiftest of fishes. When they come up to the surface for fresh breath, they make a croaking noise, dip their beaks frequently in the water, and play and dive about near the surface, like the bonita. Penguins have great powers of abstinence, and are able to live four or five months without food. Stones have been occasionally found in their stomachs, but they generally live on shrimps and crustacea, gorging themselves sometimes to excess. The sensations of these curious birds do not seem to be very acute. Sparrman stumbled over a sleeping one, and kicked it some yards, without disturbing its rest; and Forster left a number of Penguins apparently lifeless, while he went in pursuit of others, but they afterwards got up and marched off with their usual gravity.

The bird is named from the Welsh word, Pengwyn. White head (pen, head; gwyn, white), and is thought to have been given to the bird by some Welsh sailors, on seeing its white breast. Davis, who discovered, in 1585, the straits which are named after him, was of Welsh parents. Might he not have given the name Pengwyn to the bird? Swainson considers the Penguins, on the whole, as the most singular of all aquatic birds; and he states that they clearly point out that nature is about to pass from the birds to the fishes. Others consider Penguins more satisfactorily to represent some of the aquatic reptiles, especially the marine testudinata.

PELICANS AND CORMORANTS.

Pelicans are described as a large, voracious, and wandering tribe of birds, living for the most part on the ocean, and seldom approaching land but at the season of incubation. They fly with ease, and even with swiftness. Their bill is long, and armed at the end with an abrupt hook; the width of the gape is excessive; the face is generally bare of feathers, and the skin of the throat sometimes so extensible as to hang down like a bag; it will occasionally contain ten quarts. "By this curious organization," observes Swainson, "the Pelicans are able to swallow fish of a very large size; and the whole family may be termed oceanic vultures."

The neighbourhood of rivers, lakes, and the sea-coast, is the haunt of the Pelican, and they are rarely seen more than twenty leagues from the land. Le Vaillant, upon visiting Dassen Island, at the entrance of Saldanha Bay, beheld, as he says, after wading through the surf, and clambering up the rocks, such a spectacle as never, perhaps, appeared to the eye of mortal. "All of a sudden there arose from the whole surface of the island an impenetrable cloud, which formed, at the distance of forty feet above our heads, an immense canopy, or, rather, a sky, composed of birds of every species and of all colours--cormorants, sea-gulls, sand-swallows, and, I believe, the whole winged tribe of this part of Africa, were here assembled." The same traveller found on the Klein-Brak river, whilst waiting for the ebb-tide, thousands of Pelicans and Flamingoes, the deep rose-colour of the one strongly contrasting with the white of the other.

Mr. Gould says the bird is remarkable for longevity and the long period requisite for the completion of its plumage. The first year's dress is wholly brown, then fine white. The rosy tints are only acquired as the bird advances in age, and five years are required before the Pelican becomes fully mature. The expanse of wings is from twelve to thirteen feet. Although the bird perches on trees, it prefers rocky shores. It is found in the Oriental countries of Europe; and is common on the rivers and lakes of Hungary and Russia, and on the Danube. That the species exists in Asia there is no doubt. Belon, who refers to Leviticus xi. 18, where the bird is noted as unclean, says that it is frequent on the lakes of Egypt and Judæa. "When he was passing the plain of Roma, which is only half a day's journey from Jerusalem, he saw them flying in pairs, like swans, as well as in a large flock. Hasselquist saw the Pelican at Damietta, in Egypt. "In flying, they form an acute angle, like the common wild geese when they migrate. They appear in some of the Egyptian drawings."--(Rossellini.)

Von Siebold saw the Pelican in Japan. "Pelicans," says Dr. Richardson, "are numerous in the interior of the fur countries, but they seldom come within two hundred miles of Hudson's Bay. They deposit their eggs usually on small rocky islands, on the brink of cascades, where they can scarcely be approached; but they are otherwise by no means shy birds. They haunt eddies under waterfalls, and devour great quantities of carp and other fish. When gorged with food they doze on the water, and may be easily captured, as they have great difficulty in taking wing at such times, particularly if their pouches be loaded with fish."

The bird builds on rocky and desert shores: hence we read of "the Pelican of the wilderness," alluded to in these beautiful lines:--

"Like the Pelicans On that lone island where they built their nests, Nourish'd their young, and then lay down to die."

The bird lives on fish, which it darts upon from a considerable height. James Montgomery thus describes this mode of taking their prey:--

"Eager for food, their searching eyes they fix'd On Ocean's unroll'd volume, from a height That brought immensity within their scope; Yet with such power of vision look'd they down, As though they watch'd the shell-fish slowly gliding O'er sunken rocks, or climbing trees of coral, On indefatigable wing upheld, Breath, pulse, existence, seem'd suspended in them; They were as pictures painted on the sky; Till suddenly, aslant, away they shot, Like meteors chang'd from stars in gleams of lightning. And struck upon the deep; where, in wild play, Their quarry flounder'd, unsuspecting harm. With terrible voracity they plunged Their heads among the affrighted shoals, and beat A tempest on the surges with their wings, Till flashing clouds of foam and spray conceal'd them. Nimbly they seized and secreted their prey, Alive and wriggling, in th' elastic net Which Nature hung beneath their grasping beaks; Till, swoll'n with captures, th' unwieldy burthen Clogg'd their slow flight, as heavily to land These mighty hunters of the deep return'd. There on the cragged cliffs they perched at ease, Gorging their hapless victims one by one; Then, full and weary, side by side they slept, Till evening roused them to the chase again."

Pelican Island.

Great numbers of Pelicans are killed for their pouches, which are converted by the native Americans into purses, &c. When carefully prepared, the membrane is as soft as silk, and sometimes embroidered by Spanish ladies for work-bags, &c. It is used in Egypt by the sailors, whilst attached to the two under chaps, for holding or baling water.
