Oculto, or Tucotuco, a rare rodent with mole-like habits.
Gray fox, abundant in the semiarid regions.
As the sun set, large flocks of blue-crowned parrakeets flew screaming overhead to seek their sleeping-quarters in the tops of the gnarled, stunted trees; and gray-throated parrakeets hurried to their bulky stick nests to chatter and quarrel before settling for the night. The latter species is an abundant bird in the Chaco of Brazil and Paraguay as well as in the Argentine. In the Argentine its range extends eastward into the province of Tucuman, while it is most plentiful in Santiago del Estero. They are extremely noisy and live and travel in flocks of a dozen to several thousand individuals. Should one approach a tree in which a band is feeding or resting, all chatter is hushed. But the birds crane their necks and noiselessly clamber to points of vantage from which they suspiciously eye the intruder. Then there is a sudden burst of wild screams as the whole colony takes wing and swiftly departs at great speed. They feed largely upon the thistle and on cactus fruits as well as on grain when it is to be had.
The nests vary in size from those containing not more than an armful of twigs, and occupied by a single pair of birds, to huge structures weighing several hundred pounds and harboring a dozen families. Frequently three or four nests are placed in the same tree, and usually a number of trees in a given area are occupied. The ground beneath the domiciles is strewn with a thick litter of old nesting material that has fallen from the disused bulky masses above.
The nesting cavities are in the under-side of the “apartments,” and entrance to them is gained through tubular openings underneath, which prevents opossums from entering them. It is not unusual to find a family of the marsupials living in a cavity in the upper part of the structure, but so strongly are the twigs interlaced that they are unable to tear their way through the thorny mass to the toothsome morsels that are so tantalizingly near. The birds occupy the nests throughout the year and it is rare to find them entirely deserted at any hour of the day. The eggs are white, slightly glossy, and of an oval shape; five to eight comprise a set. With the approach of darkness small birds seemed to disappear among the cacti. The secretario kept up a constant fusillade with his sling, but he was a poor shot and did no damage.
Finally the judge suggested supper, so we sat down on a fallen cactus trunk from which the spines had decayed, and enjoyed the bread, sausage, and tangerines which the boy fished out of the bag containing his pebbles and sundry articles; then, in answer to our call, a plump Quechua squaw brought a gourd of water from her near-by hovel; we gave her a cigarette in return, which pleased her so much that she showed us a wonderful vizcacha village not far distant, which, she said, harbored the largest and fattest of the rodents to be found in the district; she also agreed to take charge of our game so that we would not be hampered with it the rest of the evening.
The great silvery moon now began to peep above the cloudless horizon, and in a few minutes the whole country was flooded with light. Not a plant grew on the broad acres the Indian woman had pointed out; there was only the dead stump of a cactus here and there, but these loomed tall and ghostlike in the mellow light. Soon we heard deep, guttural grunts, followed by shrill squeaks, and in a low tone the judge said “vizcachas.” Then he dug down into his pockets and produced some beeswax and cotton, so each of us fixed a small fluff on the sight of our guns, and were then ready for business. We had not gone a hundred yards, after this, when the judge pointed to a mound ahead, and there, looming high above the yellow earth, sat some great, restless creature, squeaking and grunting. My companion had explained to me the business of stalking, a score of times, so I set out as directed, making a wide détour in order to get behind a cactus stump; but I am afraid the excitement was too great and I went too fast, for the first thing I knew there was a glimpse of a fleeting, shadowy form, a sharp, shrill squeal, and the mound was bare.
A few minutes later we could make out another animal some little distance away, so the judge went after it; he crept up cautiously, pausing at frequent intervals; then there was a bright flash, followed by a loud report, and we all rushed forward to pick up the first vizcacha. His disappointment was great when he found that he had “potted” a nice little cactus stump.
It was not long before we saw another of the animals. It being my turn, I began to stalk, profiting by past experience. The creature was outlined clearly, and frequently it sat up to look about; then the white breast showed distinctly. When the vizcacha sat up, I stopped; when it dropped down on all fours, I crept on. At forty yards I took the shot, and this time luck was with us. When we reached the spot the animal was tumbling about, and the judge yelled not to touch it, as they can inflict serious wounds with their sharp teeth and claws. At this stage of the game the secretario came in for his share of the work; he followed the dancing form in its erratic course, and finally dealt it a blow on the neck with the blunt side of the machete, killing it. It was a splendid specimen, weighing a trifle over eighteen pounds, as we later discovered. It differed from the species found in the high mountains in having a shorter tail and coarse fur, besides being much larger; the appearance of the former had always brought to my mind a combination of a squirrel and a rabbit; this creature was, well, simply a vizcacha; there is nothing else like it. The color is slaty-blue on the back and white underneath.
