AUCHENIA LLAMA. _Desmarest._

Guanaco of the aborigines of Chile.

“The Guanaco abounds over the whole of the temperate parts of South

America, from the wooded islands of Tierra del Fuego, through Patagonia,

the hilly parts of La Plata, Chile, even to the Cordillera of Peru. I

saw several of these animals in Navarin Island, forty miles north of

Cape Horn; the Guanaco, therefore, has, with the exception of a fox and

mouse, inhabitants of the same island, the most southern range of all

American quadrupeds. Although preferring an elevated site, it yields in

this respect to its near relative the Vicuña. On the plains of Southern

Patagonia, we saw them in greater numbers than in any other part.

Generally they go in small herds, from half a dozen to thirty together;

but on the banks of the Santa Cruz, we saw one herd, which must have

contained at least five hundred. On the northern shores of the Strait of

Magellan they are also very numerous. The Guanacoes are generally wild

and extremely wary: Mr. Stokes told me, that he one day in Patagonia saw

through a glass a herd of these beasts, which evidently had been

frightened, and were running away at full speed, although their distance

was so great that they could not be distinguished by the naked eye.

“The sportsman frequently receives the first intimation of their

presence, by hearing from a long distance their peculiar shrill neighing

note of alarm. If he then looks attentively, he will, perhaps, see the

herd standing in a line on the side of some distant hill. On

approaching, a few more squeals are given, and then off they set, at an

apparently slow but really quick canter, along some narrow beaten track

to a neighbouring hill. If, however, by chance he should abruptly meet a

single animal, or several together, they will generally stand

motionless, and intently gaze at him;—then, perhaps, move on a few

yards, turn round, and look again. What is the cause of this difference

in their shiness? Do they mistake a man in the distance for their chief

enemy the puma? Or does curiosity overcome their timidity? That they are

curious is certain, for if a person lies on the ground, and plays

strange antics, such as throwing up his feet in the air, they will

almost always approach by degrees to reconnoitre him. It is an artifice

that was repeatedly practised with success by the sportsman of the

Beagle, and it had moreover the advantage of allowing several shots to

be fired, which were all taken as parts of the performance. On the

mountains of Tierra del Fuego, and in other places, I have more than

once seen a Guanaco on being approached, not only neigh and squeal, but

prance and leap about in the most ridiculous manner, apparently in

defiance, as a challenge. These animals are very easily domesticated,

and I have seen some in this state near the houses in northern

Patagonia, although at large on their native plains. They are, when thus

kept, very bold, and readily attack a man, by striking him from behind

with both knees. It is asserted, that the motive for these attacks is

jealousy on account of their females. The wild Guanacoes, however, have

no idea of defence; and even a single dog will secure one of these large

animals, till the huntsman can come up. In many of their habits they are

like sheep in a flock. Thus when they see men approaching in several

directions on horseback, they soon become bewildered, and know not which

way to run. This circumstance greatly facilitates the Indian method of

hunting, for they are thus easily driven to a central point, and are

encompassed.

“The Guanacoes readily take to the water; several times at Port Valdes

they were seen swimming from island to island. Byron, in his voyage,

says he saw them drinking salt water. Some of our officers likewise saw

a herd apparently drinking the briny fluid from a Salina near Cape

Blanco; and in several parts of the country, if they do not drink salt

water, I believe they drink none at all. In the middle of the day, they

frequently roll in the dust, in saucer-shaped hollows. The males often

fight together; one day two passed quite close to me, squealing and

trying to bite each other; and several were shot with their hides deeply

scored. Herds appear sometimes to set out on exploring parties: at Bahia

Blanca, where within thirty miles of the coast these animals are

extremely scarce, I one day saw the tracks of thirty or forty, which had

come in a direct line to a muddy salt water creek. They then must have

perceived, that they were approaching the sea, for they had wheeled with

the regularity of cavalry, and had returned back in as straight a line,

as they had advanced. The Guanacoes have one singular habit, the motive

of which is to me quite inexplicable, namely, that on successive days

they drop their dung on one defined heap. I saw one of these heaps,

which was eight feet in diameter, and necessarily was composed of a

large quantity. Frezier remarks on this habit as common to the Guanaco

as well as to the Llama;[13] he says it is very useful to the Indians,

who use the dung for fuel, and are thus saved the trouble of collecting

it.

“The Guanacoes appear to have favourite spots for dying in. On the banks

of the Santa Cruz, the ground was actually white with bones in certain

circumscribed spaces, which generally were bushy and all near the river.

On one such spot I counted between ten and twenty heads. I particularly

examined the bones; they did not appear, as some scattered ones which I

had seen, gnawed or broken as if dragged together by a beast of prey.

The animals in most cases, must have crawled, before dying, beneath and

amongst the bushes. Mr. Bynoe informs me, that during the last voyage,

he observed the same circumstances on the banks of the Rio Gallegos. I

do not at all understand the reason of this; but I may add, that the

Guanacoes which were wounded on the plains near the Santa Cruz

invariably walked towards the river. This quadruped seems particularly

liable to contain in its stomach bezoar stones. The Indians who trade at

the Rio Negro, bring great numbers to sell as Remedios or quack

medicines; and I saw one old man with a box quite full of them, large

and small.”—D.
