ANIMALS OF THE NEIGHBOURHOOD OF EGA

Scarlet-faced Monkeys--Parauacu Monkey--Owl-faced Night-apes-- Marmosets--Jupura--Bats--Birds--Cuvier's Toucan--Curl-crested Toucan--Insects--Pendulous Coc.o.o.ns--Foraging Ants--Blind Ants

As may have been gathered from the remarks already made, the neighbourhood of Ega was a fine field for a Natural History collector. With the exception of what could be learned from the few specimens brought home, after transient visits by Spix and Martius and the Count de Castelnau, whose acquisitions have been deposited in the public museums of Munich and Paris, very little was known in Europe of the animal tenants of this region; the collections that I had the opportunity of making and sending home attracted, therefore, considerable attention. Indeed, the name of my favourite village has become quite a household word among a numerous cla.s.s of Naturalists, not only in England but abroad, in consequence of the very large number of new species (upwards of 3000) which they have had to describe, with the locality ”Ega”

attached to them. The discovery of new species, however, forms but a small item in the interest belonging to the study of the living creation. The structure, habits, instincts, and geographical distribution of some of the oldest-known forms supply inexhaustible materials for reflection. The few remarks I have to make on the animals of Ega will relate to the mammals, birds, and insects, and will sometimes apply to the productions of the whole Upper Amazons region. We will begin with the monkeys, the most interesting, next to man, of all animals.

Scarlet-faced Monkeys--Early one sunny morning, in the year 1855, I saw in the streets of Ega a number of Indians, carrying on their shoulders down to the port, to be embarked on the Upper Amazons steamer, a large cage made of strong lianas, some twelve feet in length and five in height, containing a dozen monkeys of the most grotesque appearance. Their bodies (about eighteen inches in height, exclusive of limbs) were clothed from neck to tail with very long, straight, and s.h.i.+ning whitish hair; their heads were nearly bald, owing to the very short crop of thin grey hairs, and their faces glowed with the most vivid scarlet hue. As a finish to their striking physiognomy, they had bushy whiskers of a sandy colour, meeting under the chin, and reddish-yellow eyes. These red-faced apes belonged to a species called by the Indians Uakari, which is peculiar to the Ega district, and the cage with its contents was being sent as a present by Senor Chrysostomo, the Director of Indians of the j.a.pura, to one of the Government officials at Rio Janeiro, in acknowledgment of having been made colonel of the new National Guard. They had been obtained with great difficulty in the forests which cover the lowlands near the princ.i.p.al mouth of the j.a.pura, about thirty miles from Ega. It was the first time I had seen this most curious of all the South American monkeys, and one that appears to have escaped the notice of Spix and Martius. I afterwards made a journey to the district inhabited by it, but did not then succeed in obtaining specimens; before leaving the country, however, I acquired two individuals, one of which lived in my house for several weeks.

The scarlet-faced monkey belongs, in all essential points of structure, to the same family (Cebidae) as the rest of the large- sized American species; but it differs from all its relatives in having only the rudiment of a tail, a member which reaches in some allied kinds the highest grade of development known in the order. It was so unusual to see a nearly tailless monkey from America, that naturalists thought, when the first specimens arrived in Europe, that the member had been shortened artificially. Nevertheless, the Uakari is not quite isolated from its related species of the same family, several other kinds, also found on the Amazons, forming a graduated pa.s.sage between the extreme forms as regards the tail. The appendage reaches its perfection in those genera (the Howlers, the Lagothrix and the Spider monkeys) in which it presents on its under-surface near the tip a naked palm, which makes it sensitive and useful as a fifth hand in climbing. In the rest of the genera of Cebidae (seven in number, containing thirty-eight species), the tail is weaker in structure, entirely covered with hair, and of little or no service in climbing, a few species nearly related to our Uakari having it much shorter than usual. All the Cebidae, both long-tailed and short-tailed, are equally dwellers in trees. The scarlet-faced monkey lives in forests, which are inundated during great part of the year, and is never known to descend to the ground; the shortness of its tail is, therefore, no sign of terrestrial habits, as it is in the Macaques and Baboons of the Old World. It differs a little from the typical Cebidae in its teeth, the incisors being oblique and, in the upper jaw, converging, so as to leave a gap between the outermost and the canine teeth. Like all the rest of its family, it differs from the monkeys of the Old World, and from man, in having an additional grinding-tooth (premolar) in each side of both jaws, making the complete set thirty-six instead of thirty-two in number.

The white Uakari (Brachyurus calvus), seems to be found in no other part of America than the district just mentioned, namely, the banks of the j.a.pura, near its princ.i.p.al mouth; and even there it is confined, as far I could learn, to the western side of the river. It lives in small troops among the crowns of the lofty trees, subsisting on fruits of various kinds. Hunters say it is pretty nimble in its motions, but is not much given to leaping, preferring to run up and down the larger boughs in travelling from tree to tree. The mother, as in other species of the monkey order, carries her young on her back. Individuals are obtained alive by shooting them with the blow-pipe and arrows tipped with diluted Urari poison. They run a considerable distance after being pierced, and it requires an experienced hunter to track them. He is considered the most expert who can keep pace with a wounded one, and catch it in his arms when it falls exhausted. A pinch of salt, the antidote to the poison, is then put in its mouth, and the creature revives. The species is rare, even in the limited district which it inhabits. Senor Chrysostomo sent six of his most skillful Indians, who were absent three weeks before they obtained the twelve specimens which formed his unique and princely gift. When an independent hunter obtains one, a very high price (thirty to forty milreis) [Three pounds seven s.h.i.+llings to four pounds thirteen s.h.i.+llings] is asked, these monkeys being in great demand for presents to persons of influence down the river.

Adult Uakaris, caught in the way just described, very rarely become tame. They are peevish and sulky, resisting all attempts to coax them, and biting anyone who ventures within reach. They have no particular cry, even when in their native woods; in captivity they are quite silent. In the course of a few days or weeks, if not very carefully attended to, they fall into a listless condition, refuse food, and die. Many of them succ.u.mb to a disease which I suppose from the symptoms to be inflammation of the chest or lungs. The one which I kept as a pet died of this disorder after I had had it about three weeks. It lost its appet.i.te in a very few days, although kept in an airy verandah; its coat, which was originally long, smooth, and glossy, became dingy and ragged like that of the specimens seen in museums, and the bright scarlet colour of its face changed to a duller hue.

This colour, in health, is spread over the features up to the roots of the hair on the forehead and temples, and down to the neck, including the flabby cheeks which hang down below the jaws.

The animal, in this condition, looks at a short distance as though some one had laid a thick coat of red paint on its countenance. The death of my pet was slow; during the last twenty-four hours it lay prostrate, breathing quickly, its chest strongly heaving; the colour of its face became gradually paler, but was still red when it expired. As the hue did not quite disappear until two or three hours after the animal was quite dead, I judged that it was not exclusively due to the blood, but partly to a pigment beneath the skin which would probably retain its colour a short time after the circulation had ceased.

After seeing much of the morose disposition of the Uakari, I was not a little surprised one day at a friend's house to find an extremely lively and familiar individual of this species. It ran from an inner chamber straight towards me after I had sat down on a chair, climbed my legs and nestled in my lap, turning round and looking up with the usual monkey's grin, after it had made itself comfortable. It was a young animal which had been taken when its mother was shot with a poisoned arrow; its teeth were incomplete, and the face was pale and mottled, the glowing scarlet hue not supervening in these animals before mature age; it had also a few long black hairs on the eyebrows and lips. The frisky little fellow had been reared in the house amongst the children, and allowed to run about freely, and take its meals with the rest of the household. There are few animals which the Brazilians of these villages have not succeeded in taming. I have even seen young jaguars running loose about a house, and treated as pets.

The animals that I had rarely became familiar, however long they might remain in my possession, a circ.u.mstance due no doubt to their being kept always tied up.

The Uakari is one of the many species of animals which are cla.s.sified by the Brazilians as ”mortal,” or of delicate const.i.tution, in contradistinction to those which are ”duro,” or hardy. A large proportion of the specimens sent from Ega die before arriving at Para, and scarcely one in a dozen succeeds in reaching Rip Janeiro alive. The difficulty it has of accommodating itself to changed conditions probably has some connection with the very limited range or confined sphere of life of the species in its natural state, its native home being an area of swampy woods, not more than about sixty square miles in extent, although no permanent barrier exists to cheek its dispersal, except towards the south, over a much wider s.p.a.ce.

When I descended the river in 1859, we had with us a tame adult Uakari, which was allowed to ramble about the vessel, a large schooner. When we reached the mouth of the Rio Negro, we had to wait four days while the custom-house officials at Barra, ten miles distant, made out the pa.s.sports for our crew, and during this time the schooner lay close to the sh.o.r.e, with its bowsprit secured to the trees on the bank. Well, one morning, scarlet-face was missing, having made his escape into the forest. Two men were sent in search of him, but returned after several hours' absence without having caught sight of the runaway. We gave up the monkey for lost, until the following day, when he re-appeared on the skirts of the forest, and marched quietly down the bowsprit to his usual place on deck. He had evidently found the forests of the Rio Negro very different from those of the delta lands of the j.a.pura, and preferred captivity to freedom in a place that was so uncongenial to him.

The Parauacu Monkey.--Another Ega monkey, nearly related to the Uakaris, is the Parauacu (Pithecia hirsuta), a timid inoffensive creature with a long bear-like coat of harsh speckled-grey hair.

The long fur hangs over the head, half concealing the pleasing diminutive face, and clothes also the tail to the tip, which member is well developed, being eighteen inches in length, or longer than the body. The Parauacu is found on the ”terra firma”

lands of the north sh.o.r.e of the Solimoens from Tunantins to Peru.

It exists also on the south side of the river, namely, on the banks of the Teffe, but there under a changed form, which differs a little from its type in colours. This form has been described by Dr. Gray as a distinct species, under the name of Pithecia albicans. The Parauacu is also a very delicate animal, rarely living many weeks in captivity; but any one who succeeds in keeping it alive for a month or two, gains by it a most affectionate pet. One of the specimens of Pithecia albicans now in the British Museum was, when living, the property of a young Frenchman, a neighbour of mine at Ega. It became so tame in the course of a few weeks that it followed him about the streets like a dog. My friend was a tailor, and the little pet used to spend the greater part of the day seated on his shoulder, while he was at work on his board. Nevertheless,it showed great dislike to strangers, and was not on good terms with any other member of my friend's household than himself. I saw no monkey that showed so strong a personal attachment as this gentle, timid, silent, little creature. The eager and pa.s.sionate Cebi seem to take the lead of all the South American monkeys in intelligence and docility, and the Coaita has perhaps the most gentle and impressible disposition; but the Parauacu, although a dull, cheerless animal, excels all in this quality of capability of attachment to individuals of our own species. It is not wanting, however, in intelligence as well as moral goodness, proof of which was furnished one day by an act of our little pet. My neighbour had quitted his house in the morning without taking Parauacu with him, and the little creature having missed its friend, and concluded, as it seemed, that he would be sure to come to me, both being in the habit of paying me a daily visit together, came straight to my dwelling, taking a short cut over gardens, trees, and thickets, instead of going the roundabout way of the street. It had never done this before, and we knew the route it had taken only from a neighbour having watched its movements. On arriving at my house and not finding its master, it climbed to the top of my table, and sat with an air of quiet resignation waiting for him. Shortly afterwards my friend entered, and the gladdened pet then jumped to its usual perch on his shoulder.

Owl-laced Night Apes--A third interesting genus of monkeys found near Ega, are the Nyctipitheci, or night apes, called Ei-a by the Indians. Of these I found two species, closely related to each other but nevertheless quite distinct, as both inhabit the same forests, namely, those of the higher and drier lands, without mingling with each other or intercrossing. They sleep all day long in hollow trees, and come forth to prey on insects and eat fruits only in the night. They are of small size, the body being about a foot long, and the tall fourteen inches, and are thickly clothed with soft grey and brown fur, similar in substance to that of the rabbit. Their physiognomy reminds one of an owl, or tiger-cat: the face is round and encircled by a ruff of whitish fur. the muzzle is not at all prominent; the mouth and chin are small; the cars are very short, scarcely appearing above the hair of the head; and the eyes are large and yellowish in colour, imparting the staring expression of nocturnal animals of prey.

The forehead is whitish, and decorated with three black stripes, which in one of the species (Nyctipithecus trivirgatus) continue to the crown; and in the other (N. felinus), meet on the top of the forehead. N. trivirgatus was first described by Humboldt, who discovered it on the banks of the Ca.s.siquiare, near the head waters of the Rio Negro.

I kept a pet animal of the N. trivirgatus for many months, a young one having been given to me by an Indian compadre, as a present from my newly-baptised G.o.dson. These monkeys, although sleeping by day, are aroused by the least noise; so that, when a person pa.s.ses by a tree in which a number of them are concealed, he is startled by the sudden apparition of a group of little striped faces crowding a hole in the trunk. It was in this way that my compadre discovered the colony from which the one given to me was taken. I was obliged to keep my pet chained up; it therefore, never became thoroughly familiar. I once saw, however, an individual of the other species (N. felinus) which was most amusingly tame. It was as lively and nimble as the Cebi, but not so mischievous and far more confiding in its disposition, delighting to be caressed by all persons who came into the house.

But its owner, the Munic.i.p.al Judge of Ega, Dr. Carlos Mariana, had treated it for many weeks with the greatest kindness, allowing it to sleep with him at night in his hammock, and to nestle in his bosom half the day as he lay reading. It was a great favourite with everyone, from the cleanliness of its habits to the prettiness of its features and ways. My own pet was kept in a box, in which was placed a broad-mouthed gla.s.s jar; into this it would dive, head foremost, when any one entered the room, turning round inside, and thrusting forth its inquisitive face an instant afterwards to stare at the intruder. It was very active at night, venting at frequent intervals a hoa.r.s.e cry, like the suppressed barking of a dog, and scampering about the room, to the length of its tether, after c.o.c.kroaches and spiders. In climbing between the box and the wall, it straddled the s.p.a.ce, resting its hands on the palms and tips of the out-stretched fingers with the knuckles bent at an acute angle, and thus mounted to the top with the greatest facility. Although seeming to prefer insects, it ate all kinds of fruit, but would not touch raw or cooked meat, and was very seldom thirsty. I was told by persons who had kept these monkeys loose about the house, that they cleared the chambers of bats as well as insect vermin. When approached gently my Ei-a allowed itself to be caressed; but when handled roughly, it always took alarm, biting severely, striking out its little hands, and making a hissing noise like a cat. As already related, my pet was killed by a jealous Caiarara monkey, which was kept in the house at the same time.

Barrigudo Monkeys.--Ten other species of monkeys were found, in addition to those already mentioned, in the forests of the Upper Amazons. All were strictly arboreal and diurnal in their habits, and lived in flocks, travelling from tree to tree, the mothers with their children on their backs-- leading, in fact, a life similar to that of the Pararauate Indians, and, like them, occasionally plundering the plantations which lie near their line of march. Some of them were found also on the Lower Amazons, and have been noticed in former chapters of this narrative. Of the remainder, the most remarkable is the Macaco barrigudo, or bag- bellied monkey of the Portuguese colonists, a species of Lagothrix. The genus is closely allied to the Coaitas, or spider monkeys, having, like them, exceedingly strong and flexible tails, which are furnished underneath with a naked palm like a hand, for grasping. The Barrigudos, however, are very bulky animals, while the spider monkeys are remarkable for the slenderness of their bodies and limbs. I obtained specimens of what have been considered two species, one (L. olivaceus of Spix?) having the head clothed with grey, the other (L.

Humboldtii) with black fur. They both live together in the same places, and are probably only differently-coloured individuals of one and the same species. I sent home a very large male of one of these kinds, which measured twenty-seven inches in length of trunk, the tail being twenty-six inches long; it was the largest monkey I saw in America, with the exception of a black Howler, whose body was twenty-eight inches in height. The skin of the face in the Barrigudo is black and wrinkled, the forehead is low, with the eyebrows projecting, and, in short, the features altogether resemble in a striking manner those of an old negro.

In the forests, the Barrigudo is not a very active animal; it lives exclusively on fruits, and is much persecuted by the Indians, on account of the excellence of its flesh as food. From information given me by a collector of birds and mammals, whom I employed, and who resided a long time among the Tucuna Indians near Tabatinga, I calculated that one horde of this tribe, 200 in number, destroyed 1200 of these monkeys annually for food. The species is very numerous in the forests of the higher lands, but, owing to long persecution, it is now seldom seen in the neighbourhood of the larger villages. It is not found at all on the Lower Amazons. Its manners in captivity are grave, and its temper mild and confiding, like that of the Coaitas, owing to these traits, the Barrigudo is much sought after for pets; but it is not hardy like the Coaitas, and seldom survives a pa.s.sage down the river to Para.

Marmosets.-It now only remains to notice the Marmosets, which form the second family of American monkeys. Our old friend Midas ursulus, of Para and the Lower Amazons, is not found on the Upper river, but in its stead a closely-allied species presents itself, which appears to be the Midas rufoniger of Gervais, whose mouth is bordered with longish white hairs. The habits of this species are the same as those of the M. ursulus, indeed it seems probable that it is a form or race of the same stock, modified to suit the altered local conditions under which it lives. One day, while walking along a forest pathway, I saw one of these lively little fellows miss his grasp as he was pa.s.sing from one tree to another along with his troop. He fell head foremost, from a height of at least fifty feet, but managed cleverly to alight on his legs in the pathway, quickly turning around, gave me a good stare for a few moments, and then bounded off gaily to climb another tree. At Tunantins, I shot a pair of a very handsome species of Marmoset, the M. rufiventer, I believe, of zoologists. Its coat was very glossy and smooth, the back deep brown, and the underside of the body of rich black and reddish hues. A third species (found at Tabatinga, 200 miles further west) is of a deep black colour, with the exception of a patch of white hair around its mouth. The little animal, at a short distance, looks as though it held a ball of snow-white cotton in its teeth. The last I shall mention is the Hapale pygmaeus, one of the most diminutive forms of the monkey order, three full-grown specimens of which, measuring only seven inches in length of body, I obtained near St. Paulo. The pretty Lilliputian face is furnished with long brown whiskers, which are naturally brushed back over the cars. The general colour of the animal is brownish-tawny, but the tail is elegantly barred with black. I was surprised, on my return to England, to learn from specimens in the British Museum, that the pigmy Marmoset was found also in Mexico-- no other Amazonian monkey being known to wander far from the great river plain. Thus, the smallest and apparently the feeblest, species of the whole order, is one which has, by some means, become the most widely dispersed.

The Jupura.--A curious animal, known to naturalists as the Kinkajou, but called Jupura by the Indians of the Amazons, and considered by them as a kind of monkey, may be mentioned in this place. It is the Cercoleptes caudivolvus of zoologists, and has been considered by some authors as an intermediate form between the Lemur family of apes and the plantigrade Carnivora, or Bear family. It has decidedly no close relation s.h.i.+p to either of the groups of American monkeys, having six cutting teeth to each jaw, and long claws instead of nails, with extremities of the usual shape of paws instead of hands. Its muzzle is conical and pointed, like that of many Lemurs of Madagascar; the expression of its countenance, and its habits and actions, are also very similar to those of Lemurs. Its tail is very flexible towards the tip, and is used to twine round branches in climbing. I did not see or hear anything of this animal while residing on the Lower Amazons, but on the banks of the Upper river, from the Teffe to Peru, it appeared to be rather common. It is nocturnal in its habits, like the owl-faced monkeys, although, unlike them, it has a bright, dark eye. I once saw it in considerable numbers, when on an excursion with an Indian companion along the low Ygapo sh.o.r.es of the Teffe, about twenty miles above Ega. We slept one night at the house of a native family living in the thick of the forest where a festival was going on and, there being no room to hang our hammocks under shelter. on account of the number of visitors, we lay down on a mat in the open air, near a shed which stood in the midst of a grove of fruit-trees and pupunha palms.

Past midnight, when all became still, after the uproar of holidaymaking, as I was listening to the dull, fanning sound made by the wings of impish hosts of vampire bats crowding round the Caju trees, a rustle commenced from the side of the woods, and a troop of slender, long-tailed animals were seen against the clear moonlit sky, taking flying leaps from branch to branch through the grove. Many of them stopped at the pupunha trees, and the hustling, twittering, and screaming, with sounds of falling fruits, showed how they were employed. I thought, at first, they were Nyctipitheci, but they proved to be Jupuras, for the owner of the house early next morning caught a young one, and gave it to me. I kept this as a pet animal for several weeks, feeding it on bananas and mandioca-meal mixed with treacle. It became tame in a very short time, allowing itself to be caressed, but making a distinction in the degree of confidence it showed between myself and strangers. My pet was unfortunately killed by a neighbour's dog, which entered the room where it was kept. The animal is so difficult to obtain alive, its place of retreat in the daytime not being known to the natives, that I was unable to procure a second living specimen.

Bats--The only other mammals that I shall mention are the bats, which exist in very considerable numbers and variety in the forest, as well as in the buildings of the villages. Many small and curious species, living in the woods, conceal themselves by day under the broad leaf-blades of Heliconiae and other plants which grow in shady places; others cling to the trunks of trees.

While walking through the forest in the daytime, especially along gloomy ravines, one is almost sure to startle bats from their sleeping-places; and at night they are often seen in great numbers flitting about the trees on the shady margins of narrow channels. I captured altogether, without giving especial attention to bats, sixteen different species at Ega.

The Vampire Bat.--The little grey blood-sucking Phyllostoma, mentioned in a former chapter as found in my chamber at Caripi, was not uncommon at Ega, where everyone believes it to visit sleepers and bleed them in the night. But the vampire was here by far the most abundant of the family of leaf-nosed bats. It is the largest of all the South American species, measuring twenty-eight inches in expanse of wing. Nothing in animal physiognomy can be more hideous than the countenance of this creature when viewed from the front; the large, leathery ears standing out from the sides and top of the head, the erect spear-shaped appendage on the tip of the nose, the grin and the glistening black eye, all combining to make up a figure that reminds one of some mocking imp of fable. No wonder that imaginative people have inferred diabolical instincts on the part of so ugly an animal. The vampire, however, is the most harmless of all bats, and its inoffensive character is well known to residents on the banks of the Amazons. I found two distinct species of it, one having the fur of a blackish colour, the other of a ruddy hue, and ascertained that both feed chiefly on fruits. The church at Ega was the headquarters of both kinds, I used to see them, as I sat at my door during the short evening twilights, trooping forth by scores from a large open window at the back of the altar, twittering cheerfully as they sped off to the borders of the forest. They sometimes enter houses; the first time I saw one in my chamber, wheeling heavily round and round, I mistook it for a pigeon, thinking that a tame one had escaped from the premises of one of my neighbours. I opened the stomachs of several of these bats, and found them to contain a ma.s.s of pulp and seeds of fruits, mingled with a few remains of insects. The natives say they devour ripe cajus and guavas on trees in the gardens, but on comparing the seeds taken from their stomachs with those of all cultivated trees at Ega, I found they were unlike any of them; it is therefore, probable that they generally resort to the forest to feed, coming to the village in the morning to sleep, because they find it more secure from animals of prey than their natural abides in the woods.

Birds.--I have already had occasion to mention several of the more interesting birds found in the Ega district. The first thing that would strike a newcomer in the forests of the Upper Amazons would be the general scarcity of birds; indeed, it often happened that I did not meet with a single bird during a whole day's ramble in the richest and most varied parts of the woods. Yet the country is tenanted by many hundred species, many of which are, in reality, abundant, and some of them conspicuous from their brilliant plumage. The cause of their apparent rarity is to be sought in the sameness and density of the thousand miles of forest which const.i.tute their dwelling-place. The birds of the country are gregarious, at least during the season when they are most readily found; but the frugivorous kinds are to be met with only when certain wild fruits are ripe, and to know the exact localities of the trees requires months of experience. It would not be supposed that the insectivorous birds are also gregarious, but they are so-- numbers of distinct species, belonging to many different families, joining together in the chase or search of food. The proceedings of these a.s.sociated bands of insect-hunters are not a little curious, and merit a few remarks.

While hunting along the narrow pathways that are made through the forest in the neighbourhood of houses and villages, one may pa.s.s several days without seeing many birds; but now and then the surrounding bushes and trees appear suddenly to swarm with them.
