Wanderings In South America by Charles Waterton (chromebook ebook reader .txt) 📖

the young of other birds or touch carrion. The larger is called bouradi by the Indians (which means nose), the other scirou. They seem partial to each other's company, and often resort to the same feeding-tree and retire together to the same shady noon-day retreat. They are very noisy in rainy weather at all hours of the day, and in fair weather at morn and eve. The sound which the bouradi makes is like the clear yelping of a puppy-dog, and you fancy he says "pia-po-o-co," and thus the South-American Spaniards call him piapoco.

All the toucanets feed on the same trees on which the toucan feeds, and every species of this family of enormous bill lays its eggs in the hollow trees. They are social, but not gregarious. You may sometimes see eight or ten in company, and from this you would suppose they are gregarious; but upon a closer examination you will find it has only been a dinner-party, which breaks up and disperses towards roosting-time.

You will be at a loss to conjecture for what ends Nature has overloaded the head of this bird with such an enormous bill. It cannot be for the offensive, as it has no need to wage war with any of the tribes of animated nature, for its food is fruits and seeds, and those are in superabundance throughout the whole year in the regions where the toucan is found. It can hardly be for the defensive, as the toucan is preyed upon by no bird in South America and, were it obliged to be at war, the texture of the bill is ill-adapted to give or receive blows, as you will see in dissecting it. It cannot be for any particular protection to the tongue, as the tongue is a perfect feather.

The flight of the toucan is by jerks: in the action of flying it seems incommoded by this huge disproportioned feature, and the head seems as if bowed down to the earth by it against its will. If the extraordinary form and size of the bill expose the toucan to ridicule, its colours make it amends. Were a specimen of each species of the toucan presented to you, you would pronounce the bill of the bouradi the most rich and beautiful: on the ridge of the upper mandible a broad stripe of most lovely yellow extends from the head to the point; a stripe of the same breadth, though somewhat deeper yellow, falls from it at right angles next the head down to the edge of the mandible; then follows a black stripe, half as broad, falling at right angles from the ridge and running narrower along the edge to within half an inch of the point. The rest of the mandible is a deep bright red. The lower mandible has no yellow: its black and red are distributed in the same manner as on the upper one, with this difference, that there is black about an inch from the point. The stripe corresponding to the deep yellow stripe on the upper mandible is sky-blue. It is worthy of remark that all these brilliant colours of the bill are to be found in the plumage of the body and the bare skin round the eye.

All these colours, except the blue, are inherent in the horn: that part which appears blue is in reality transparent white, and receives its colour from a thin piece of blue skin inside. This superb bill fades in death, and in three or four days' time has quite lost its original colours.

Till within these few years no idea of the true colours of the bill could be formed from the stuffed toucans brought to Europe. About eight years ago, while eating a boiled toucan, the thought struck me that the colours in the bill of a preserved specimen might be kept as bright as those in life. A series of experiments proved this beyond a doubt. If you take your penknife and cut away the roof of the upper mandible, you will find that the space betwixt it and the outer shell contains a large collection of veins and small osseous fibres running in all directions through the whole extent of the bill. Clear away all these with your knife, and you will come to a substance more firm than skin, but of not so strong a texture as the horn itself. Cut this away also, and behind it is discovered a thin and tender membrane: yellow where it has touched the yellow part of the horn, blue where it has touched the red part, and black towards the edge and point; when dried this thin and tender membrane becomes nearly black; as soon as it is cut away nothing remains but the outer horn, red and yellow, and now become transparent. The under mandible must undergo the same operation. Great care must be taken and the knife used very cautiously when you are cutting through the different parts close to where the bill joins on to the head: if you cut away too much the bill drops off; if you press too hard the knife comes through the horn; if you leave too great a portion of the membrane it appears through the horn and, by becoming black when dried, makes the horn appear black also, and has a bad effect. Judgment, caution, skill and practice will ensure success.

You have now cleared the bill of all those bodies which are the cause of its apparent fading, for, as has been said before, these bodies dry in death and become quite discoloured, and appear so through the horn; and reviewing the bill in this state, you conclude that its former bright colours are lost.

Something still remains to be done. You have rendered the bill transparent by the operation, and that transparency must be done away to make it appear perfectly natural. Pound some clean chalk and give it enough water till it be of the consistency of tar, add a proportion of gum-arabic to make it adhesive, then take a camel-hair brush and give the inside of both mandibles a coat; apply a second when the first is dry, then another, and a fourth to finish all. The gum-arabic will prevent the chalk from cracking and falling off. If you remember, there is a little space of transparent white in the lower mandible which originally appeared blue, but which became transparent white as soon as the thin piece of blue skin was cut away: this must be painted blue inside. When all this is completed the bill will please you: it will appear in its original colours. Probably your own abilities will suggest a cleverer mode of operating than the one here described. A small gouge would assist the penknife and render the operation less difficult.

The houtou ranks high in beauty amongst the birds of Demerara. His whole body is green, with a bluish cast in the wings and tail; his crown, which he erects at pleasure, consists of black in the centre, surrounded with lovely blue of two different shades; he has a triangular black spot, edged with blue, behind the eye extending to the ear, and on his breast a sable tuft consisting of nine feathers edged also with blue. This bird seems to suppose that its beauty can be increased by trimming the tail, which undergoes the same operation as our hair in a barber's shop, only with this difference, that it uses its own beak, which is serrated, in lieu of a pair of scissors. As soon as his tail is full grown, he begins about an inch from the extremity of the two longest feathers in it and cuts away the web on both sides of the shaft, making a gap about an inch long. Both male and female adonise their tails in this manner, which gives them a remarkable appearance amongst all other birds. While we consider the tail of the houtou blemished and defective, were he to come amongst us he would probably consider our heads, cropped and bald, in no better light. He who wishes to observe this handsome bird in his native haunts must be in the forest at the morning's dawn. The houtou shuns the society of man: the plantations and cultivated parts are too much disturbed to engage it to settle there; the thick and gloomy forests are the places preferred by the solitary houtou.

In those far-extending wilds, about daybreak, you hear him articulate, in a distinct and mournful tone, "houtou, houtou." Move cautious on to where the sound proceeds from, and you will see him sitting in the underwood about a couple of yards from the ground, his tail moving up and down every time he articulates "houtou." He lives on insects and the berries amongst the underwood, and very rarely is seen in the lofty trees, except the bastard siloabali-tree, the fruit of which is grateful to him. He makes no nest, but rears his young in a hole in the sand, generally on the side of a hill.

While in quest of the houtou, you will now and then fall in with the jay of Guiana, called by the Indians ibibirou. Its forehead is black, the rest of the head white, the throat and breast like the English magpie; about an inch of the extremity of the tail is white, the other part of it, together with the back and wings, a greyish changing purple; the belly is white. There are generally six or eight of them in company: they are shy and garrulous, and tarry a very short time in one place. They are never seen in the cultivated parts.

Through the whole extent of the forest, chiefly from sunrise till nine o'clock in the morning, you hear a sound of "wow, wow, wow, wow." This is the bird called boclora by the Indians. It is smaller than the common pigeon, and seems, in some measure, to partake of its nature: its head and breast are blue; the back and rump somewhat resemble the colour on the peacock's neck; its belly is a bright yellow. The legs are so very short that it always appears as if sitting on the branch: it is as ill-adapted for walking as the swallow. Its neck, for above an inch all round, is quite bare of feathers, but this deficiency is not seen, for it always sits with its head drawn in upon its shoulders. It sometimes feeds with the cotingas on the guava- and hitia-trees, but its chief nutriment seems to be insects, and, like most birds which follow this prey, its chaps are well armed with bristles: it is found in Demerara at all times of the year, and makes a nest resembling that of the stock-dove. This bird never takes long nights, and when it crosses a river or creek it goes by long jerks.

The boclora is very unsuspicious, appearing quite heedless of danger: the report of a gun within twenty yards will not cause it to leave the branch on which it is sitting, and you may often approach it so near as almost to touch it with the end of your bow. Perhaps there is no bird known whose feathers are so slightly fixed to the skin as those of the boclora. After shooting it, if it touch a branch in its descent, or if it drop on hard ground, whole heaps of feathers fall off: on this account it is extremely hard to procure a specimen for preservation. As soon as the skin is dry in the preserved specimen the feathers become as well fixed as those in any other bird.

Another species, larger than the boclora, attracts much of your notice in these wilds: it is called cuia by the Indians, from the sound of its voice.
