When swimming, very little of their bodies appear above water, and their necks are extended a little forward,--their progress being slow.
The rhea is hunted by the Gauchos and Indians on horseback. The huntsmen form a semicircle, gradually closing in on the bird, which does not know in which way to escape. It generally runs off against the wind; at the same time, when it first starts, it expands its wings, and, like a vessel, makes sail. As the huntsman gets close to it he throws his la.s.so over its neck; or if he is using the bolas, he casts them so as to entangle the bird"s-legs, and thus bring it to the ground.
The rhea is easily tamed, and is constantly seen about the huts of the Patagonians.
In the southern part of Patagonia another species, much smaller, exists,--the Avestris petise, now called Struthio Darwinii, in compliment to the naturalist who has described it. He states that not more than fifteen eggs are found in the nest of the petise, deposited by two or more females. This bird does not expand its wings when first starting at full speed, after the manner of the northern kind. It is a smaller and more graceful bird: its white feathers are tipped with black at the extremities, and the black ones in like manner are tipped with white.
A third species, the large-billed rhea (Rhea macrorhyncha), has been discovered. These birds in vast numbers inhabit the wide-extended plains, and afford a welcome addition to the food of their roving inhabitants.
CARACARA POLYBORUS.
The largest caracara--Polyborus Braziliensis--ranges the gra.s.sy savannahs of La Plata. Across the desert, between the rivers Negro and Colorado, numbers constantly attend the line of road, to devour the carca.s.ses of the exhausted animals which chance to perish from fatigue and thirst. It also attends the estancias and slaughtering-houses, accompanied by its smaller relative, the chimango. "When an animal dies on the plain the gallinaso commences the feast, and then the two species of polyborus pick the bones clean," says Darwin. These birds, although thus commonly feeding together, are far from being friends. When the caracara is quietly seated on the branch of a tree or on the ground, the chimango often continues for a long time flying backwards and forwards, up and down, in a semicircle, trying each time at the bottom of the curve to strike its larger relative. The caracara takes little notice, except by bobbing its head. The caracaras are crafty, and steal numbers of eggs; they also attempt, together with the chimango, to pick off the scabs from the sore backs of horses and mules. These false eagles rarely kill any living bird or animal; and their vulture-like, necrophagous habits are very evident to any one who has fallen asleep on the desolate plains; for, when he awakes, he will see on each surrounding hillock one of these birds patiently watching him with an evil eye. If a party of men go out hunting with dogs and horses, they will be accompanied during the day by several of these attendants.
The flight of the caracara is heavy and slow, and it is generally an inactive, tame, and cowardly bird. It destroys young lambs, by tearing the umbilical cord; and it pursues the gallinaso till that bird is compelled to vomit up the carrion it may have recently gorged. It is said, also, that several caracaras will unite in chase of large birds, even such as herons.
The chimango is tame and fearless; and when an animal is killed a number soon collect, and patiently wait, standing on the ground on all sides.
Darwin describes seeing one pounce on a dog which was lying asleep close to one of a party of sportsmen. They had difficulty in preventing their canine companion from being seized before their eyes.
It will frequently wait, as does the caracara, at the mouth of a rabbit-hole, and seize on the animal when it comes out. It is also very mischievous and inquisitive. It will pick up almost anything from the ground: a large black glazed hat was carried nearly a mile, as were a pair of heavy bolas. On another occasion a small Kater"s compa.s.s in a red morocco case was carried off, and never recovered. These birds are, moreover, quarrelsome and very pa.s.sionate, tearing up the gra.s.s with their bills in their rage. They are noisy, too, uttering several harsh cries--one of them like that of the English rook.
OWLS OF THE PAMPAS (ATHENE CUNICULAEIA).
The traveller across the Pampas will see a number of little owls-- generally seated in pairs, during the evening, on the hillocks near the burrows of the bizcacha, occasionally uttering their strange wild hoots to each other. If disturbed, they either run into the holes of their friends, in which they have their abode; or, uttering a shrill, harsh cry, they move with a remarkably undulatory flight to a short distance, and then turning round, steadily gaze at their pursuer.
THE PAMPAS CUCKOO (MOLOTHRUS NIGER).
Among the birds of numerous kinds which abound on the plains, there are several worthy of notice. One is remarkable from its habits.
It deposits its eggs, like the cuckoo, in the nests of other birds.
Several of them may be seen standing together on the back of a cow or horse. They also perch on low boughs: and while pluming themselves in the sun, attempt to sing; but their voice is rather like a hiss, resembling that of bubbles of air pa.s.sing rapidly from a small orifice under water, so as to produce an acute sound.
THE CALANDRIA (MINA ORPHEUS).
The best songster on the Pampas is a species of mocking-bird, called by the inhabitants calandria. Its song is powerful--similar to that of the hedge-warbler. It only sings, however, during the spring; at other times its cry is harsh and inharmonious. They frequent the neighbourhood of houses; and will boldly peck at the meat which is hung up on the posts or walls to dry. When any of the other small birds join the feast, the calandria soon chases them away.
FLAMINGOES.
The flamingo, in large flocks, visits the New World as well as the Old.
On the sh.o.r.es of the great rivers, as also on the banks of lagoons and marshes, it may be seen feeding with other water-fowl--its beautiful red and white plumage shining brightly in the sun, and contrasting with the dark green of the river vegetation.
OVEN-BIRDS.
Of the genus Furnarius there are several species. The best-known is the oven-bird of La Plata--the casara, or house-maker, of the Spaniards. It builds its nest in an exposed situation, on the top of a vast bare rock or cactus. It is composed of mud and bits of straw, and has strong, thick walls--its shape being precisely that of an oven, or depressed bee-hive. The opening is large and arched, and directly in front.
Within the nest there is a part.i.tion which reaches nearly to the roof, thus forming a pa.s.sage or ante-chamber to the true nest.
THE LITTLE HOUSE-BUILDER.
There is another species of Furnarius, which the Spaniards call the casarita, or little house-builder. This species builds its nest at the bottom of a narrow cylindrical hole, which extends horizontally to nearly six feet under ground. It generally chooses the side of a low bank, but sometimes penetrates the mud walls round the houses, through which it works its way, frequently--very much to its disappointment-- coming out unexpectedly on the opposite side.
THE SCISSOR-BEAK.
The scissor-beak (Rhynchops nigra) frequents the lakes and streams. It is about the size of a tern, with short legs, webbed feet, and extremely long, pointed wings. The beak is flattened laterally, and the lower mandible is an inch and a half longer than the upper. When flying along in small flocks, close to the surface of a lake, the birds keep their bills wide open, the lower mandible half buried in the water. In their flight they frequently twist about with extreme swiftness, managing, with their projecting lower mandible, to plough up small fish, which they retain in the lower half of their scissor-like bills. Each bird thus leaves its wake on the mirror-like surface. On quitting the water their flight is wild, irregular, and rapid. They then utter loud, harsh cries; their tails, as they fly, are much used in steering their irregular course.
During the day they may generally be seen resting in flocks on the gra.s.sy plains, at some distance from the water, as they usually take to fishing at night.
PARROTS.
A small green parrot, with a grey breast, frequents the banks of the Parana. It builds on the higher branches of the taller trees.
These birds fly in large flocks, and commit great ravages on the corn-fields.
THE BOAT-BILL HERON.
In the same localities the curious boat-bill heron is found,--its short thick neck and enormous beak giving it a clumsy, ungainly look alongside the elegant flamingo. The beak may be likened to two boats, laid one upon the other, gunwale to gunwale, the upper part of the mandible representing the keel. It feeds on the Crustacea which it picks up on the sh.o.r.e, as well as on fish--on which it pounces, as they swim by, from some branch overhanging the water.
It is about the size of a duck, its legs being shorter, in proportion to its body, than those of waders in general. On the top of its head the male has a full, long plume of black feathers drooping over the back.
The neck and breast are of a greyish-white. The back also is grey, with a wash of rusty-red; while there is a patch of a deeper tint of the same colour upon the middle of the under part of the body. The sides are black, and the tail white.
Although many other creatures besides those which have been described are to be found in the vast regions we have rambled over, none of the larger or more curious have been omitted. We have, however, been able to take only a very cursory glance at the human inhabitants or the wonders of the vegetable kingdom; but it is hoped that the reader will have gained a general and correct view of the various aspects which the wilder portions of the Western World present, as well as of the animals with which the Creator, in his infinite wisdom, has thought fit to people them.
Quitting America, we purpose,--in future volumes,--to wander over the Eastern portions of the globe, the islands of the Pacific, Australasia, and the Indian Archipelago, and to visit the Arctic and Antarctic regions,--where numberless objects are to be found, not less interesting and wonderful than those described in the preceding pages.
