SOME CLEVER MONKEYS[402-*]
By Thomas Belt
On the dryer ridges near the Artigua River, a valuable timber tree, the “nispera,” as it is called by the native, is common. It grows to a great size, and its timber is almost indestructible; so that we used it in the construction of all our permanent works. White ants do not eat it, nor, excepting when first cut, and before it is barked, do any of the wood-boring beetles. It bears a round fruit about the size of an apple, hard and heavy when green, and at this time is much frequented by the large yellowish-brown spider-monkey, which roams over the tops of the trees in bands of from ten to twenty. Sometimes they lay quiet until I was passing underneath, when, shaking a branch of the nispera tree, they would send down a shower of the hard round fruit; but fortunately I was never struck by them. As soon as I looked up, they would commence yelping and barking, and putting on the most threatening gestures, breaking off pieces of branches and letting them fall, and shaking off more fruit, but never throwing anything, simply letting it fall. Often, when on lower trees, they would hang from the branches two or three together, holding on to each other and to the branch with their fore feet and long tail, whilst their hind feet hung down, all the time making threatening gestures and cries.
Sometimes a female would be seen carrying a young one on its back, to which it clung with legs and tail, the mother making its way along the branches, and leaping from tree to tree, apparently but little encumbered with its baby. A large black and white eagle is said to prey upon them, but I never saw one, although I was constantly falling in with troops of the monkeys. Don Francisco Velasquez, one of our officers, told me that one day he heard a monkey crying out in the forest for more than two hours, and at last, going out to see what was the matter, he saw a monkey on a branch and an eagle beside it trying to frighten it to turn its back, when it would have seized it. The monkey, however, kept its face to its foe, and the eagle did not care to engage with it in this position, but probably would have tired it out. Velasquez fired at the eagle, and frightened it away. I think it likely, from what I have seen of the habits of this monkey, that they defend themselves from its attack by keeping two or three together, thus assisting each other, and that it is only when the eagle finds one separated from its companions that it dares to attack it.
Sometimes, but more rarely, a troop of the white-faced cebus monkey would be fallen in with, rapidly running away, throwing themselves from tree to tree. This monkey feeds also partly on fruit, but is incessantly on the look-out for insects, examining the crevices in trees and withered leaves, seizing the largest beetles and munching them up with the greatest relish. It is also very fond of eggs and young birds, and must play havoc among the nestlings. Probably owing to its carnivorous habits, its flesh is not considered so good by monkey eaters as that of the fruit-feeding spider-monkey.
