Perhaps you have yourself witnessed the proof. You have seen one ant rob another of its crumb of bread, that by a laborious effort has been carried far. You have seen the companions of both gather around the spot, deprive the despoiler of its ill-gotten prize, restore the crumb to its lawful possessor, and punish the would-be pilferer. If you have not seen this, others have,—myself among the number. Surely, it is reason; surely, it is moral perception. If not, what is it? The closet-naturalist calls it instinct,—a ready word to cloak that social cowardice which shrinks from acknowledging that besides man there are other beings upon the earth with talents worth saving.
Soon after the ant-eater had gone to sleep, a little bird about the size of a starling was seen flitting about. It was of the ordinary shape of the shrikes, or fly-catchers, and, like them, of sombre plumage,—a dull grey blended with bluish slate. As already said, it was flitting about among the tree-tops, now and then rising above them, and hovering for a while in the air; then lighting again upon a branch, and from this hopping to another, and another, all the time giving utterance to twittering but scarcely musical notes.
“An ant-thrush,” Munday said. “It’s hunting about for the very creatures that are swarming on that log. If it should spy them we’ll have no more trouble with the tocandeiras. That friend will clear them out of our way. If it but gets its eye on that red crowd, it’ll treat them very differently from what the beast has done. In twenty minutes there won’t be a tocandeira to sting us. May the Great Spirit prove propitious, and turn its eyes upon the dead-wood!”
For a time the bird kept up its flickering flight and twittering cry, while our adventurers watched it manoeuvres, keeping quiet, as a precaution against scaring it away. All at once the ant-thrush changed its tactics, and its louder note proclaimed a surprise. It had come close to the tree that contained the tamandua, and saw the quadruped taking its siesta upon the branch. From the presence of the ant-eater it argued the proximity of their common prey.
The swarm of fire-ants, reddening the log, formed too conspicuous an object to escape being seen. The ant-thrush soon saw them, and announced the discovery with a screech, which was a signal to scores of hungry companions. It was answered by what seemed a hundred echoes, and soon the air resounded with whistling wings, as the feathered ant-eaters came crowding to the feast.
Boy reader, you have bred pigeons, and fed them too. You have flung before them whole baskets of barley, and pecks of oats, until the pavement was thickly strewed. You have observed how quickly they could clear the ground of the grain. With the like rapidity was the log cleared of the tocandeiras. In ten minutes not a single insect could be seen upon it; and then the feathered ant-eaters, without giving the tamandua a hint that his premises had been despoiled, flew off into the forest in search of a fresh swarm.
