Part 20

The Humming-birds are the most lovely of the winged race. Nature seems to have endowed them with her rarest gifts. In creating them she surpassed herself, and exhausted all the charms at her disposal; for she gave them grace, elegance, rapidity of motion, magnificence of plumage, and indomitable courage. What can be more delightful than the sight of these little feathered beauties, flashing with the united fires of the ruby, the topaz, the sapphire, and the emerald, flying from flower to flower amid the richest tropical vegetation? Such are the lightness and rapidity of some of the smaller species, that the eye can scarcely follow the quick beat of their wings. When they hover they appear perfectly motionless, and one might fancy them suspended by an invisible thread.

Specially adapted for life in the air, they are unceasingly in motion, searching for their food in the calyx of flowers, from which they drink the nectar with so much gentleness that the plant is scarcely stirred. But the juice and honey of flowers, as some authors affirm, are not their only food—such unsubstantial diet would be insufficient to sustain the great activity displayed almost every moment of their existence.

The tongue of the Humming-bird is a microscopic instrument of marvellous arrangement. It is composed of two half-tubes placed one against the other, capable of opening and shutting, like a pair of pliers. Moreover, it is constantly moistened by a glutinous saliva, by which it is enabled to seize and hold Insects.

Proud of their gay colors, the Humming-birds take the greatest care to protect their plumage. They frequently dress themselves by passing their feathers through their bills.

The nest of the Humming-bird is a masterpiece. It is about the size of half an apricot. These consist of lichens, and are most artistically interwoven, the crevices being closed up with the Bird’s saliva; the interior is padded with the silky fibres furnished by various plants. This pretty cradle is suspended to a leaf, sometimes to a small branch of rushes, or even to the straw roof of a hut. The Bird lays twice a year a pair of pure white eggs, about the size of a pea.

These little creatures are universally admired for their elegance and beauty, and the names given them are generally descriptive of their excessive minuteness. The creoles of the Antilles call them Murmurers; the Spaniards Picaflores; the Brazilians, Shupaflores, or Flower-suckers; finally, the Indians call these darlings Sunbeams.

Among the most formidable enemies of the Humming-bird may be reckoned the Monster Spider, which spins its web round their nests, and devours eggs or young; even the old Birds are sometimes its victims.

Humming-birds are scattered over the greater part of South and North America, even as far north as Canada; but in Brazil and Guiana they are most abundant. At least 500 species are known. Among the more remarkable species we may note the Topaz-throated Trochilus, a native of Brazil; the Sickle-winged Humming-bird; the Double-crested Humming-bird; Gould’s Humming-bird; Cora Humming-bird; the Giant Humming-bird, which attains the size of a Swallow; the Dwarf Humming-bird, whose size does not exceed that of a bee; the Bar-tailed Humming-bird or Sapho Comet, a native of Eastern Peru; the Racket-tailed Humming-bird, so named from the shape of its tail, which spreads out at the extremity in the form of a racket; the Crested Humming-bird, with a double crest on the head of the male Bird; and the Sword-bill Humming-bird, with a bill as long as the whole body of the Bird.

THE CROWS.

The Crows are divided into four groups or sub-genera—namely, the Crows properly so called, Pies, Jays and Nutcrackers.

The genus Corvus, or Crow family, as limited by modern Naturalists, comprehends the Raven, the Carrion Crow, the Royston or Hooded Crow, the Rook, the Jackdaw, Great-billed Crow, Philippine Crow and Fish Crow.

All these species have in many respects the same characteristics, and the same habits. With the exception of the Raven and Magpie, which live in pairs, the others reside together in companies, whether they are in quest of their daily food or roosting for the night. They are all possessed of intelligence, cunning, mischievous habits, the gift of imitation, though in different degrees, and the same provident habit of amassing provisions in secret places. This last peculiarity in the tamed Birds degenerates into a perfect mania, which leads them to carry off and hide everything that attracts or pleases their eye, especially gems and bright articles of metal. The whole group are easily tamed.

The Crows, especially the Raven and the Carrion Crow, are omnivorous. Living or dead flesh, Insects, eggs, fruit, seeds—nothing comes amiss to their palate.

The Ravens possess a vigorous and sustained flight; they have a keen sense of smell and excellent vision. By exercising these latter qualities they quickly learn where food is to be obtained, and as they wing towards it they constantly utter their cry, as if inviting their companions to join them; this croak, as it is called, is harsh and dissonant. Their plumage being of a sombre black, and their voice so unmusical, have doubtless been the reasons why they have long been considered Birds of ill omen. When taken young, they are tamed with great facility, for they will neither rejoin their own race nor desert the neighborhood where they have been kindly treated. True, they may go into the fields to seek for food, but when the increasing shadows predict the approach of night, their familiar resting place in the house of their protector will be sought. They become much attached to those who take notice of them, and will recognize them even in a crowd.

THE DIPPERS.

The Dippers or Water Wrens have straight and slender bills; large and stout toes, furnished with strong hooked claws, and short wings and tails. The decidedly aquatic habits of these Birds form a curious exception to the rest of the Sparrow family. They live constantly on the edge of the water, or in the water itself, hunting for the Insects which constitute their food.

Although their toes are not webbed, they may often be noticed diving and moving about under water, by extending their wings and using them as fins. They are frequently seen flying along streams, and catching the winged Insects skimming over the surface of the water. They build their nests along the banks of mountain streams, and thrive in great numbers in such rocky countries as the Alps, Pyrenees, and other mountain chains in the south, west and north of Europe.

Fishes.

THE numerous Fishes that inhabit the waters all over the globe are divided into two great groups—the Cartilaginous Fishes, with their framework made up of bones in the form of cartilage or gristle, and the Osseous, or bony Fishes. These large groups are sub-divided in a most puzzling manner by many Naturalists. The long Latin and Greek names used to classify these groups and smaller families are so much more difficult to remember than are the divisions of the great group of Mammals, that we will entirely discard all these derivations and explanations, using only the common English names for grouping them according to their peculiarities of form, the arrangement of the gills, the number and form of their fins, etc., etc.

The first great group of Cartilaginous Fishes is divided into three sections, which make in reality four families, as the second section comprises two. In the first of these we find the queer family of Lampreys, in which the mouth forms a sucker. In the second, are the family of Raias, and the Shark family, characterized by their mouth being furnished with jaws. The third includes the Sturgeons, which are distinguished by having the gills free.

The Bony Fishes are divided into four great sections. The first is represented by the family of Globe Fish and Coffers, which have the jaw attached to the cranium. The second includes the queer family of Pipe-fish and Sea-horses, which have the gills divided into round tufts arranged in pairs. The third division includes the family of soft-finned Fishes, in which the rays of the fins are soft. In the fourth section are the various families of spiny-finned Fishes. And in some one of these groups with their distinct characteristics, may be classified all the numerous Fishes that are known to modern Naturalists.

CARTILAGINOUS FISHES.

THE LAMPREYS AND THE EELS.

It is not usual to class these two families together, but they look so much alike until studied closely, all the different varieties having the appearance of serpents, with fins and curious forms of tails and heads, that it seems best to study them together and find the points of difference. The Lamprey is of a lighter color than the Eel, and is not so graceful, but of a rather clumsy form. But it differs most in its mouth, which is round, and placed below the end of the nose. It resembles the mouth of a Leech more than that of an Eel.

The Lamprey has a hole on top of its head through which it spouts water, somewhat like a Whale, and the fins are formed by a lengthening out of the skin instead of having a set of bones or spines for that purpose. The mouth of the Lamprey is not only formed like that of the Leech, but it has the same property of sticking close to and sucking any body that is applied to it. It has a wonderful power of holding on to stones by sucking with its mouth, so that it is almost impossible to draw it away. We are told of one that weighed only three pounds, and yet it stuck so firmly to a stone weighing twelve pounds, that it remained suspended by its mouth, and it was almost impossible to make it loosen its hold.

This wonderful strength of suction is supposed to arise from the power of the Lamprey to exhaust the air within its body by the hole over the nose, while the mouth is closely fixed to the object, and allows no air to enter.

This adhesive or sticking quality in the Lamprey is somewhat increased by the slimy substance which is smeared all over its body. This substance serves to keep it warm in the cold water, and it also keeps its skin soft and pliant.

Every year, usually about the beginning of the spring, the Lampreys leave the sea, where they usually make their home, and make holes or nests in the gravelly bottoms of rivers. Here the eggs are laid, and the mother Lamprey watches near until the eggs hatch. Then she is often seen with her whole family playing about her until they have become well grown, when she takes the whole family back in triumph to the ocean.

There are several different species belonging to the Lamprey family. The kind known as the Lesser Lamprey inhabits Europe, Japan and the lakes of South America. It measures from twelve to fifteen inches long. Then there is a still smaller member of the family called the Lampern, which lives in European rivers, and is about six or seven inches long. It hides itself under stones or in the mud, but does not have the same power of suction as some of the larger ones.

The Sea Lamprey belongs to the Mediterranean. When full grown it is about three feet long, and its light yellow body is marbled with brown. The Lampreys feed on worms, molluscs and small Fishes. The larger ones often seize Fishes of great size, and suck them like a Leech.

All the different kinds of Lampreys are considered very fine and delicate food, and horrible stories are told of how kings and emperors used to raise the best kinds of Lampreys in ponds and feed them by throwing into the ponds live slaves who had displeased them; as they considered the Lamprey had a finer flavor when fed on human flesh. But only one man, a senator of Rome, was really known to do such a dreadful thing, and we are told that when Augustus, the emperor, heard it he ordered all these ponds to be filled up; but not until after many poor slaves had met this awful death, simply because they did not happen to please their wicked master.

THE EELS.

The Eels belong to the family of bony Fishes, although the Lampreys which they resemble in general appearance, belong to the family of Fishes whose framework is made up of cartilage, or gristle. The Eels form a very large family if we would include the different kinds of bony Fishes that have the same snake-like form of the common Eel. We find these smaller families classed under the name of Apoda; this word means without feet when applied to animals, but when used to describe Fishes, means without the ventral fins which serve in the place of feet.

As the different kinds of Eels found under this family of Apoda are described by their Greek or Latin names, it will be well for us to understand the meaning of each of the four divisions. We would hardly recognize the plain Sand Eel, when we find him classed with “Osseous Fishes” under the name of “Ammodytes,” yet this is where the Naturalists place him, because this word in Latin means a sand-burrower, a kind of serpent, and is also derived from two Greek words meaning sand, and diver. The Electrical Eel is classed under fresh water Fishes under the name of Gymnotus, which comes from two Greek words meaning naked and back, showing that the back of the Electrical Eel is without fins. The Sea Eel is classed under the name of Muraenas, while Anguilla, which means snaky, serpent-like, is used to describe the plain Eels with smooth bodies and very few of the characteristics which distinguish the other Eels.

We will simply give all these different kinds of Eels their plain common name, but when we read of wonderful fresh water Fishes called Gymnotus Electricus, who have strange electrical powers, we will know the word is used to describe the Electrical Eel.

ELECTRICAL EELS.

Very strange stories are told of these Eels, and its power to give an Electric shock to any person or animal who touches it. Alexander von Humboldt is said to have given the first precise account of this very curious Eel. This celebrated Naturalist tells of a voyage up the Orinoco for the purpose of studying the Electrical Eel, great numbers of which are found in the neighborhood of this river. Some Indians conducted the party to the Cano de Bera, a muddy pond surrounded by rich vegetation, Indian figs and beautiful flowers.

The party of Naturalists were surprised when they learned that it would be necessary to use about thirty half-wild Horses to help them fish for the Electrical Eel, and that the severe shocks of electricity given by the Eels must be expended upon the Horses before it would be safe to touch the Eels.

While our hosts were explaining to us this strange mode of fishing, the troop horses and mules had arrived, and the Indians had made a sort of battue, pressing the horses on all sides, and forcing them into the marsh. The Indians, armed with long canes and harpoons, placed themselves round the basin, some of them mounting the trees, whose branches hung over the water, and by their cries, and still more by their canes, prevented the horses from landing again.

The Eels, stunned by the noise, defended themselves by repeated discharges of their batteries. For a long time it seemed as if they would be victorious over the Horses. Some of the Mules especially, being almost stifled by the frequency and force of the shock, disappeared under the water, and some of the Horses, in spite of the watchfulness of the Indians, regained the bank, where, overcome by the shocks they had undergone, they stretched themselves at their whole length.

The picture presented was now indescribable. Groups of Indians surrounded the basin; the Horses with bristling mane, terror and grief in their eyes, trying to escape from the storm which had surprised them; the Eels, yellow and livid, looking like great aquatic Serpents swimming on the surface of the water, and chasing their enemies, were objects at once appalling and picturesque. In less than five minutes two Horses were drowned.

When the struggle had lasted a quarter of an hour, the Mules and Horses appeared less frightened, the manes became more natural, the eyes expressed less terror, the Eels shunned, in place of attacking them; at the same time approaching the bank, when they were easily taken by throwing little harpoons at them attached to long cords; the harpoon, sometimes hooking two at a time, being landed by means of the long cord. They were drawn ashore without being able to communicate any shock.

Having landed the Eels, they were transported to little pools dug in the soil, and filled with fresh water; but such is the terror they inspire, that none of the people of the country would release them from the harpoon—a task which the travelers had to perform themselves, and receive the first shock, which was not slight—the most energetic surpassing in force that communicated by a Leyden jar, completely charged.

The Electrical Eel surpasses in size and strength all the other Electric Fishes. Humboldt saw them five feet three inches long. They vary in color according to age, and the nature of the muddy water in which they live. Beneath, the head is of a fine yellow color mixed with red; the mouth is large, and furnished with small teeth arranged in many rows.

The Electrical Eel gives the most frightful shocks without the least muscular movement in the fins, in the head, or any other part of the body. The shock, indeed, depends upon the will of the animal, and in this respect differs from a Leyden jar, which is discharged by communicating with two opposite poles. It happens sometimes that an Electrical Eel, seriously wounded, only gives a very weak shock, but if, thinking it exhausted, it is touched fearlessly, its discharge is terrible.

SEA EELS.

The Sea Eels are slender, serpent-like Fishes, that are very strong and active, and they swim with the same waving movements in the water, as the serpents use in creeping on dry land. These Eels feed on small Fishes, Crabs, etc., and are such hungry fellows that when other food fails they begin to nibble at each other’s tails.

It is difficult to catch a Sea Eel; they are usually caught with rod and line, or with line and ground bait, but they are quick in making their escape. When they have swallowed a hook they will often cut the line with their teeth, or they turn upon it, and try, by winding it round some object, to strain or break it. When caught in a net they quickly choose some mesh through which their body can glide.

Like the Lampreys, these Sea Eels make excellent food, and are often raised in ponds and carefully fed to give their flesh a delicate flavor.

SAND EELS.

The Sand Eel is an easily frightened little fellow who buries himself in the sand. He is quite handsome, being silvery-blue—brighter on the lower parts than on the upper, with the radiating fins first white and then blue in color.

This Eel is seldom seen swimming about. It hollows out a burrow for itself in the sand to the depth of fifteen or twenty inches, where it hunts out worms on which it feeds, while it shelters itself from the jaws of the hungry Fishes which eagerly hunt for its delicate flesh.

COMMON EELS.

The plain, snake-like Eel classed under the name of Anguilla is found in European rivers, and in various parts of North America. Although it is sometimes eaten it is not considered especially good for food; it does not often measure much over two feet in length, and is covered with a soft, slimy skin, and sometimes with tiny scales almost too small to be seen.

CONGER EELS.

The Conger Eel of the United States which belongs to this family is often five feet or more in length, while the Conger Eel of Europe is very large, as thick as a man’s leg, and sometimes ten feet long.

THE FAMILY OF RAIAS, OR FLAT-FISH.

All the curious Fish of this family—which forms the second group of the Cartilaginous Fishes—are broad, and swim flat on the water, and they are distinguished by the spines or prickles which the different species have on various parts of their body, or on the tail.

It is by these spines that the different members of this family are distinguished from each other. The Skate has the middle of the back rough, and a single row of spines on the tail. The Sharp-nosed Ray has ten spines that are situated towards the middle of the back. The Rough Ray has its spines spread over the whole back. The Fire-flare has but one spine but that is a terrible one. This dangerous weapon is placed on the tail, about four inches from the body, and is about five inches long. It is of flinty hardness; the sides are thin, sharp-pointed, and closely and sharply bearded the whole way.

The White Ray, the Lump-fish and the Torpedo or Cramp-fish are the most important of this family, and these curious specimens are worthy of special description.

THE WHITE RAY.

The mouth of this Fish is placed in the lower part of the head, and far from the extremity of the nose; it is furnished with many rows of hooked and pointed teeth. The eyes, which are on the upper part of the head are half projecting and are protected by an elastic skin which covers the head. Immediately behind the eyes are two blow-holes which are connected with the interior of the mouth. The Fish is able to open and close these holes at pleasure, by means of a membrane which acts as a sort of valve. Through these holes it ejects the surplus water that is not required for respiration. In its general color this Fish is ashy grey on its upper surface; and white, with rows of black spots below.

Its tail is long, flexible and slender and is used as a rudder, and as a weapon. When lying in wait for its prey at the bottom of the sea, and it has no desire to change its position, a rapid and sudden stroke of this formidable weapon, armed with hooked bones on its upper surface, arrests its victim by wounding or killing it, without disturbing the mud or sea-weed by which the Fish is covered. This species often grows to be quite large, and their flesh is firm and nourishing, but the larger specimens seldom approach inhabited shores.

THE LUMP-FISH.

This is one of the largest of the Ray family. It sometimes reaches a length of twelve feet, and being excellent eating, is much sought after by fishermen. It is commonly seen with the Skate-fish in European markets, as it inhabits all the European seas.

A ray of great curving spines extends all along the back of the Lump-fish, to the end of the tail. Two similar spines are above and two below the point of the nose. Two others are placed before, and three behind the eyes. In fact, the whole surface of this curious Lump-fish fairly bristles with large and small spines, and because of this it is sometimes called the Buckler-fish; for these spines are not merely for ornament, but for defence. The color of the upper surface of this Fish is brown with light spots. The tail, which often exceeds the body in length, has three small fins at the end.

Ray-fish of all kinds are inhabitants of the deep sea, but they change according to the seasons. While stormy weather prevails they hide themselves in the depth of the ocean, where they lie in ambush, creeping along the bottom. But they do not always live at the bottom; they rise occasionally to the surface, far from shore, eagerly chasing other inhabitants of the deep, lashing the water with their tails and fins, springing out of the water, and making it foam with their sport.

When pursuing their prey they use their great fins which resemble wings, and with these and their tail, they beat the waters in order to fall unexpectedly upon their prey, as the Eagle swoops upon its victim.

THE TORPEDO, OR CRAMP FISH.
