CHAPTER VII.

_STORKS, HERONS, AND PELICAN TRIBE._

The Storks, Herons, and Pelican Tribe form a group of closely allied but externally very unlike birds, distantly related to the Petrels on the one hand, and the Cranes and Hawk Tribe on the other.

THE STORKS.

There are few birds which have figured more prominently in the realms of fairy-tale and fable than the WHITE STORK. Today it is almost universally held in affectionate regard, and in Holland, Denmark, and Germany is afforded the strictest protection, every effort being made, in localities where it is plentiful, to induce it to build its nest upon the house-roof. Sometimes, to effect this, its fondness for a stage of some sort being known, a cart-wheel is set up, and this generally proves successful, the grateful bird erecting thereon its nest. Once occupied, it may be held by several generations of tenants; and year by year additions are made to the nest, so that the original shallow structure at last attains a height of several feet. The material used in its construction consists of sticks and other substances. He considers himself a fortunate man indeed who can boast a stork's nest on his house.

To show how widespread is the regard in which this bird is held, we may mention that in Morocco, according to Colonel Irby, "almost every Moorish hovel has its stork's nest on the top, a pile of sticks lined with grass and palmetto-fibre," and he goes on to relate that in "Morocco and Fez, and some other large towns in the Moorish Empire, there is a regular storks' hospital, and that, should one be in any way injured or fall from the nest, it is sent to this institution, or rather enclosure, which is kept up by subscriptions from wealthy Moors, who regard the stork as a sacred bird."

Though the nest appears to be generally placed upon buildings, it is, when these fail, built in trees, and the selection of such sites must be regarded as representing the original practice of the species.

The stork is one of the very few birds which appear to be quite dumb. It supplies the want of a voice by a very remarkable clapping noise made by the long, horny beak. But even this noise is rarely made, and appears to be prompted by unusual excitement. "During the breeding-season," Mr. Howard Saunders tells us, "storks keep up a clappering with their bills, and this sound may frequently be heard proceeding from a number of birds circling in the air at such a height as to be almost invisible."

The affection displayed by storks for their young is proverbial. They feed them by thrusting their beaks down into the gaping little mouths, and injecting the half-digested remains of their last meal, which may represent reptile, frog, or fish, varied by a small mammal, young bird, worms, or insects.

The white stork is a really beautiful bird. Except the quill- and some of the smaller wing-feathers, which are black, the plumage is snow-white, whilst the bill and the legs are bright red. Like the swallow, it performs extensive migrations, travelling in flocks, numbering many thousands, at an immense height.

Scarcely less beautiful is the BLACK STORK, and, like its white-plumaged ally, it is also an occasional visitant to Britain. It is a handsome bird, having the plumage of the upper-parts black, richly glossed with purple, copper, and green; the under-parts pure white; and the legs and beak red. But it is far less sociable, and consequently less known, than the white stork, shunning the haunts of men, and seeking seclusion for its nest in the lofty trees of large forests.

The largest members of the Stork Tribe are the ADJUTANT-STORKS and JABIRUS. The adjutants are also, to our eyes at least, singularly ugly birds. In spite of this very natural disadvantage, they have won a very high place in the regard of the people among whom they dwell, on account of the fact that, both in Africa and India, they perform, with the vultures, the work of scavengers. Yet there is something of quaintness about these birds, if they are watched from a distance too great to reveal the character which imparts the ugliness to which we have referred, and their actions not seldom border on the grotesque. The name Adjutant has been bestowed upon them on account of the peculiar gait, which bears a fanciful resemblance to the measured pacing of an officer on parade. Like all the Storks, they have large bodies and very long legs, but they have outstripped all their relatives in the enormous size of the beak. The features which have earned this unenviable reputation for ugliness are the peculiarly unkempt and unwashed appearance of the head and neck. These are but scantily clothed in very shabby, brown-looking down-feathers; and the neck is made still more, we might almost say, repulsive by the presence of a large bare pouch, which can be distended with air to an enormous size at will. The Arabs, on account of this pouch, call the species resident with them "The Father of the Leather Bottle." Some, however, say that the correct translation of the native name would be "The Father of the Beak." But it is not only on account of their scavenging propensities that the adjutants are esteemed, for it is from the under tail-coverts of these birds that the much-prized "marabou" or "comercolly" feathers are obtained--at least the finest kinds; for some appear to be furnished by that chief of scavengers, the vulture. More precious still "is the celebrated stone called Zahir mora, or poison-killer, of great virtue and repute as an antidote to all kinds of poison," to be procured only by splitting open the head of the bird before death. Needless to say, the existence of this stone lives only in popular superstition, though how many poor birds have fallen victims thereto is not pleasant to contemplate.

Adjutants choose almost inaccessible pinnacles of rock on which to build their nests, though they sometimes nest in trees. From two to four white eggs are laid, from which, if all goes well, as many young, covered with fluffy white down, are hatched.

The JABIRUS are distant relatives of, and scarcely inferior in size to, the Adjutants. There are three species, one occurring in the Indian Peninsula, New Guinea, and Australia, one in Africa, and one in South America. It is to this last species that the name Jabiru correctly applies. Furthermore, there can be no doubt that it is one of the handsomest of its tribe. The whole plumage is pure white, and the upper-parts are made additionally resplendent by an indescribable satin-like gloss. The beautiful whiteness of its plumage is enhanced by the fact that the head and neck, bill and feet, are jet-black. Some would give the palm of beauty to the AFRICAN SADDLE-BILLED STORK. Black and white, as in the American form, are the contrasting "colours"; but the plumage of the body, instead of being pure white, is plentifully enriched with black, with beautiful purple reflections.

More or less nearly allied to the Storks are several species familiar enough to the professional ornithologist, but not very well known generally. One of the rarest and most interesting of these is the WHALE-HEADED or SHOE-BILLED STORK of the Nile, remarkable for its enormous boat-shaped bill. More common but equally interesting are the beautiful FLAMINGOES. Apart from the brilliancy of their colour, the most noticeable feature of these birds is the curious beak, which is bent downwards at a sharp angle, and provided on its inside with horny plates resembling those of the Ducks and Swans. The tongue of this bird, unlike that of the Stork Tribe generally, is thick and fleshy, and also resembles that of the duck.

The flamingo is the only member of the Stork Tribe which builds a mud-nest. Its foundation laid often in as much as 15 inches of water, and rising above the surface from 6 to 8 inches, with a diameter at the top of 15 inches, it forms a pile of no mean size. Strangely enough, though these birds are never so happy as when wading "knee" deep in water, yet after the construction of the nest the incubation of the eggs is delayed so long that before they are hatched the water has disappeared, leaving a burning plain of sun-baked mud. On the top of this nest the parent sits with its long neck neatly curled away among the back-feathers, with its long legs doubled up, and projecting behind her for some distance beyond the tail. Until quite recently it was believed that the bird incubated its eggs by sitting _astride_ the nest, the length of the legs forbidding any other position: this has now been proved beyond cavil to be an entirely erroneous opinion.

The eggs, two in number, are peculiar in that they are encased in a thick outer chalky coat, which on removal reveals a greenish-blue shell.

The characteristic crooked beak of the adult is not at all apparent in the young bird, and only appears as it approaches maturity.

The huge flocks in which these birds consort are graphically described by Mr. Abel Chapman as follows: "In herds of 300 to 400, several of which are often in sight at once, they stand feeding in the open water, all their heads under, greedily tearing up the grasses and water-plants from the bottom. On approaching them, which can only be done by extreme caution, their silence is first broken by the sentries, who commence walking away with low croaks; then hundreds of necks rise at once to full extent, every bird gaggling its loudest, as they walk obliquely away, looking back over their shoulders, as though to take stock of the extent of the danger. Pushing a few yards forward, up they all rise, and a more beautiful sight cannot be imagined than the simultaneous spreading of the crimson wings, flashing against the sky like a gleam of rosy light. In many respects these birds bear a strong resemblance to geese. Like them, flamingoes feed by day; and great quantities of grass, etc., are always floating about the muddy water when a herd has been feeding. Their cry is almost indistinguishable from the gaggling of geese, and they fly in the same catenarian formations."

The SPOONBILLS and IBISES also belong to the Stork Tribe. The former are remarkable chiefly for the strange spoon-shaped bill: one species, a few hundred years ago, nested in England. This remarkable beak is associated with a peculiar method of feeding, well described by the late Mr. Wolley. During the operation, he says, "the beak was passed sideways through the water, and kept open till something palatable came within its grasp; but the action by which the bird effected this was most singular; for instead of turning only its head and neck, it turned its whole body from left to right and from right to left, like the balance-wheel of a watch; its neck stretched out and its beak immersed perpendicularly to about half its depth: this semicircular action was kept up with great vigour and at a tolerably quick march."

A graphic description by Mr. Alfred Crowley of a visit to the breeding-haunts of the spoonbill, about fifteen miles from Amsterdam, in 1884, is well worth reproducing here: "Taking a small boat in tow, we were punted across the open water, over which were flying numbers of sand-martins, swifts, common and black terns, and black-headed gulls, the reeds being full of coots, moorhens, sedge- and reed-warblers, etc., and in the distance we saw, rising above the reeds occasionally, a small spoonbill or purple heron. On nearing a large mass of reeds, one of the boatmen struck the side of the punt with the pole, when up rose some fifty spoonbills and eight or ten purple herons; and as we came closer to the reeds there were soon hovering over our heads, within easy shot, some 200 of the former, and fifty or sixty of the latter. Strange to say, not a note or sound escaped from the spoonbills, and only a few croaks from the herons. On reaching the reeds, we moored our punt, and two of the men, wading in the mud, took us in the small boat about fifty yards through the reeds, where we found ourselves surrounded by spoonbills' nests. They were placed on the mud among the reeds, built about 1 foot or 18 inches high and 2 feet in diameter at the bottom, tapering to 1 foot at the top, where there was a slight depression, in which lay four eggs, or in most cases four young birds, many ready to leave the nest, and several ran off as we approached. In the nests with young there was a great difference in age and size, one being about a day or so old, and the oldest nearly ready to leave the nest--some two or three weeks old--so that evidently the birds lay their four eggs at considerable intervals, and begin to sit on depositing the first. After wandering about, a matter of difficulty on account of the mud, we found a clutch of only three eggs, and one of four, which I managed to blow. We also obtained two clutches of eggs of the purple heron, but some of the latter had young."

The IBISES, though much alike in form, are strangely diverse in colour. One species was sacred to the ancient Egyptians. The reverence and affection they showed to this bird, above all others, is probably largely due to its migrating habits, which obtained in that far past just as they do to-day. The naturalist Brehm says on this subject: "When the Nile, after being at its lowest ebb, rose again, and the water assumed a red tinge, then the ibis appeared in the land of the Pharaohs as a sure guarantee that the stream--the giver and preserver of life, which the people in their profound reverence raised to the rank of a god--would once again empty the well-spring of plenty over the thirsty land. The servant and messenger of an all-bounteous Deity commanded of a necessity a reverence of a poetic and distinguished character, by reason of its importance: he too must be a god."

Another species, the GLOSSY IBIS, occurs sometimes in Britain. Perhaps the most beautiful of all is the SCARLET IBIS of America, numbers of which can be seen in the Zoological Gardens of London. On account of the curved, sickle-shaped bill the Ibises were at one time believed to be related to the Curlews: this, however, is now known to be quite incorrect.

It was at one time believed that "the ibis [was] adopted as a part of the arms of the town of Liverpool. This bird is termed a _Liver_, from which that flourishing town derived its name, and is now standing on the spot where the _Pool_ was, on the verge of which the _Liver_ was killed." The arms of the town of Liverpool, however, as Mr. Howard Saunders points out, are "comparatively modern, and seem to have no reference to the ibis. The bird which was adopted in the arms of the [extinct] Earls of Liverpool was described in a former edition of 'Burke's Peerage' as a cormorant, holding in the beak a branch of seaweed. In the Plantagenet seal of Liverpool, which is believed to be of the time of King John, the bird has the appearance of a dove, bearing in its bill a sprig of olive, apparently intended to refer to the advantages that commerce would derive from peace."

The glossy ibis has been found breeding in colonies of thousands in Slavonia. The nests are large structures formed of sticks and a few weeds, never far from the water, and many even, in the colony referred to, were so near the surface that they appeared to be floating. The eggs, three or four in number, are of a beautiful greenish blue. The young, while still unable to fly, climb actively among the branches of the trees in which the nest is placed, clinging so firmly with the feet as to be removed with difficulty.

THE HERONS AND BITTERNS.

In the first mentioned of these two groups the COMMON HERON is the best known in the British Islands. Indeed, there must be few who have not encountered it in a wild state at some time or another. In suitable spots it may occasionally be met with standing mid-leg in water on the look-out for eels and other fish and frogs, a diet varied by an occasional young bird or small mammal. Sometimes this prey is hunted, so to speak, the bird walking along with a slow, measured step, striking with lightning rapidity and wonderful precision the moment its victim is sighted, whilst at others it stands motionless, as when fishing, striking the instant the unsuspecting eel or flounder comes within range.

From the earliest times until the reign of William IV. the heron was specially protected by law, being held in high regard both as an object of sport and a desirable addition to the dinner-table. So late as James I.'s time an Act was passed making it illegal to shoot with any gun within 600 paces of a heronry. The favourite way of taking the heron was by hawking, a sport which has furnished material in abundance both for poet and painter.

Herons breed in more or less extensive colonies, the nests--somewhat bulky structures, made of sticks and lined with twigs--being placed in the tops of high trees. From four to six is the normal number of eggs, and these are of a beautiful sea-green colour. The young are thinly clad in long, hairy-looking down, and for some considerable time are quite helpless.

Similar in appearance to the common heron is the American GREAT BLUE HERON, though it is by no means the largest of the herons, as its name might seem to imply. This distinction belongs to the GOLIATH HERON. A native of Africa, it is remarkable not only for its size, but for an extraordinary development of long, loose feathers hanging down from the lower part of the breast, and bearing a strange resemblance to an apron, concealing the upper part of the legs.

Passing over many species, we pause to descant on the EGRETS. These are numbered amongst the most unfortunate of birds, and this because of the gracefulness and beauty of certain parts of the plumage worn during the breeding-season, which are coveted alike by Eastern magnates and Western women. The feathers in question are those known as "egrets," or, more commonly, "ospreys"; and their collection, as Professor Newton points out, causes some of "the most abominable cruelty practised in the animal world." The wearing of these feathers can no longer be excused; for Sir William Flower in England, and Professor W. E. D. Scott in America, have given the greatest publicity to the horrible barbarities and sickening scenes which are perpetrated by the men sent to gather in this harvest. The egrets, however, are not the only victims, as a glance at the milliners' windows will show, the distorted and mangled bodies of almost every known species of the smaller birds being therein displayed! Many of those who wear these "ornaments" offend unwittingly; it is certain that if they realised the suffering and waste of life that this method of decoration entails they would eschew any but ostrich feathers for ever.

The CATTLE-EGRET, better known as the BUFF-BACKED HERON, breeds in the southern portion of the Spanish Peninsula, where from March to autumn it is very common in the marshes of Andalusia, thousands congregating there, herding with the cattle, from the backs of which they may be often seen picking off the ticks; hence the Spaniards give them a name meaning "cattle-cleaners."

The NIGHT-HERONS are comparatively small birds, and derive their name from their habit of turning night into day, waking up only as the shades of evening fall to hunt for food; only during the breeding-season is this habit broken through, when they are obliged to hunt for food for their young during the daytime. They breed in colonies, in bushes or low trees in the neighbourhood of swamps. In some places they are protected--as, for instance, round the Great Honam Temple at Canton, where these birds are held sacred.

Colonel Swinhoe, says Mr. Howard Saunders, describes the nests "as placed thickly in some venerable banyans, the granite slabs that form the pavement beneath the trees being bedaubed with the droppings of old and young, while from the nests arose the chattering cry of the callow broods, for which the parent birds were catering the whole day long, becoming more active at sunset. As darkness set in, the noise and hubbub from the trees rose to a fearful pitch."

In Hungary large numbers of herons and egrets breed together in the marshes, egrets and night-herons breeding together with the common and purple herons. Landbeck, an enthusiastic ornithologist, writes of such heronries: "The clamour in these breeding-places is so tremendous and singular in its character as almost to defy description; it must be heard before a person can form any idea of what it is like. At a distance these hideous noises blend with a confused roar, so as in some way to resemble the hubbub caused by a party of drunken Hungarian peasants; and it is only on a nearer approach the separate notes of the two species, the common and the night-heron, can be distinguished--namely, 'craik' and 'quack,' to which the notes of the young, 'zek-zek-zek,' ... in different keys, serve as an accompaniment. When close to, the noise is tremendous and the stench unbearable. This, together with the sight of dozens of young herons in every stage of putrefaction and teeming with maggots, is perfectly sickening, though the contemplation of life and movement in this immense heronry is a matter of interest to the true ornithologist.... The tops of the highest trees are usually occupied by the nests of the common heron; a little lower down is the habitation of the shy and beautiful GREAT EGRET, while in the forks of the lowest branches the night-heron takes up her abode. All these species build in one and the same tree, the nests numbering not infrequently as many as fifteen in a single tree, and yet peace invariably reigns amongst all these varieties. High over the trees appears the common heron, laden with booty, announcing his arrival with a hoarse 'craaich,' when, changing his note to a goose-like 'da-da-da-da,' he either jerks the provender down the throats of the ever-hungry youngsters or throws it up before them, when the fish are greedily swallowed, amid a desperate accompaniment of 'gohé-é-é-é, gohé-é-é-é',' a sound much resembling the frantic cry of a calf which is being lifted into a farmer's market-cart. The conduct of the more cautious egret is very different. Circling far above the nest, she first satisfies herself that no foe is hidden below before she alights among her family, which are much quieter and less hasty than their cousins. The night-herons, on the contrary, approach their nests from all sides, high and low, their crops filled with frogs, fish, and insects. A deep 'quâk' or 'gowek' announces the arrival of the old bird already from some distance, to which the young answer, while feeding, with a note resembling 'queht, queht,' or 'quehaoâheh, quehoehah'. As soon as the parents have taken their departure the youngsters recommence their concert, and from every nest uninterrupted cries of 'tzik, tzik, tzik, tzek-tzek, tzek,' and 'gétt, gétt-gétt,' are the order of the day. This amusement is varied by the nestlings climbing out among the branches till they reach the top of the tree, whence they can have a good look-out, and can see the old birds returning home from a long distance, though they are in many cases often mistaken in their identity."

A common North American bird is the so-called GREEN HERON, known by many local aliases, such as "Fly-up-the-Creek," "Chalk-line," and "Chuckle-head." Seen at short range, its plumage is lustrous and beautiful, but this disappears as soon as the bird takes wing. The nest is of very loose construction; and a story is told of one which was such a shaky concern that every time the old birds jarred it a stick fell off, and the structure grew smaller and smaller, until the day when the young were ready to fly there were but three sticks left; finally these parted, and the little herons found themselves perching on the branch that once held the nest!

THE BITTERNS.

These are birds of a remarkable type of coloration, adapted to aid their skulking habits. The coloration partakes so completely of the nature of the undergrowth among which they dwell, that, aided by certain peculiar habits described below, they succeed in harmonising so perfectly with their surroundings as to render themselves invisible to their enemies.

The best-known species is the COMMON BITTERN, though this epithet is no longer applicable, for at the present time it is but an occasional visitant to Britain. Once it was plentiful enough, as the frequent references both in prose and poetry bear witness. These references have been inspired mainly by its very peculiar note, made apparently only during the breeding-season. This sound is variously described as "booming," "bellowing," and "bumping," and many are the theories which have been invented to account for its origin. Thomson, in "The Seasons," says that it is made whilst the beak is thrust into the mud:--

The bittern knows his time, with bill ingulf'd To shake the sounding marsh.

Chaucer, that it is caused whilst it is immersed under water; and Dryden represents it as made by thrusting the bill into a reed. Mr. J. E. Harting is one of the few who have actually watched the bird during the production of the sound, and from him we gather that it is made by expelling the air from the throat whilst the head is held vertically upwards.

The protective coloration and the peculiar habits associated therewith have only recently been recognised. These birds, when threatened, do not take flight, but immediately bring the body and the long neck and pointed head into one vertical line, and remain absolutely motionless so long as the cause of alarm persists. The peculiar coloration of the body harmonises so perfectly with the surrounding undergrowth, that, as just remarked, detection is well-nigh impossible. Although the pattern and tone of the coloration vary in the various species of bittern--which occur all over the world--this principle of protection obtains in all.

The drainage of the fens is answerable for the extinction of the bittern in England.

We would draw special attention to the great length of the feathers on the neck, which, when the bird is excited, are extended on either side to form an enormous feather shield. This is admirably shown in the photograph below, which represents a bittern preparing to strike. It is a curious fact that, when extended, the hind part of the neck is protected only by a thin coat of down. When the excitement has passed, the elongated feathers fall again, and, curling round the unprotected area, give the bird the appearance of having a perfectly normally clothed neck.

A wounded bittern will strike at either man or dog, and is extremely dangerous, owing to the sharpness of its dagger-like bill. If a dog advances on one not entirely disabled, the bird immediately turns itself upon its back, and fights with beak and claws, after the fashion of a wounded hawk or owl. Owing to the way in which the neck can be tucked up, by throwing it into a series of curves, and then suddenly extended, great danger attends the approach of the unwary.

The bittern is by no means particular in its choice of food, small mammals, birds, lizards, frogs, fishes, and beetles being alike palatable. The writer remembers taking from the gullet and stomach of one of these birds no less than four water-voles, three of which had apparently been killed only just before it was shot, for the process of digestion had hardly begun.

On migration these birds appear to travel in flocks of considerable size, since Captain Kelham reports having seen as many as fifty together high up in the air, when between Alexandria and Cairo. Curiously enough, they flew like "a gaggle" of geese--in the form of a V; but every now and then he noticed they, for some reason or other, got into great confusion.

At one time the flesh of the bittern was much esteemed as food for the table, being likened in taste and colour to the leveret, with some of the flavour of wild-fowl. Sir Thomas Browne, who flourished during the middle of the seventeenth century, says that young bitterns were considered better eating than young herons.

In the fourteenth century it bred in considerable numbers in the fens of Cambridgeshire, and was so highly esteemed as a bird for the table that the taking of its eggs was forbidden. At a court-baron of the Bishop of Ely, according to Mr. J. E. Harting, held at Littleport in the eleventh year of the reign of Edward II., several people were fined for taking the eggs of the bittern and carrying them out of the fen, to the great destruction of the birds. Decreasing steadily in numbers, the bittern continued to breed in Britain till the middle of the nineteenth century, one of the last nests being taken in Norfolk in 1868.

THE PELICAN TRIBE.

The members of the Pelican Tribe may be readily distinguished from other living birds by the fact that all their toes are united in a common fold of skin or web. In the Ducks and other web-footed birds only the front toes are so united.

The Pelican Tribe embraces several apparently dissimilar forms, whose only claim to be grouped together, judged from a superficial point of view, lies in the fact that they possess the peculiar type of foot above mentioned. With the general appearance of the Pelican itself probably every one is familiar, but we had better mention here that the other representatives of the group with which we have now to deal are the Cormorants and Gannets, common on the British coasts, and the less-known Darters, Frigate-birds, and Tropic-birds; these, as we know from their anatomy, are all closely allied forms, and with the Pelicans make up a somewhat isolated group whose nearest allies appear to be the members of the Stork Tribe.

The PELICAN figures largely in ecclesiastical heraldry as the type of maternal tenderness. Tradition has it that the bird, in admonishing its young, occasionally did so with such violence as to slay them. Remorse immediately following, the distracted parent drew blood from its own breast, and therewith sprinkled the victims of its wrath, which thereupon became restored to life again. The exhaustion following on this loss of blood was so great that the young had perforce to leave the nest to procure food for themselves and the sinking parent. If any, through lack of filial affection, refused to aid in this good work, the mother, on recovering strength, drove them from her presence, but the faithful children she permitted to follow her wherever she went.

One of the most remarkable features of the pelican is the pouch which hangs suspended from the under side of the beak. This is capable of great distension, and is used, when fishing, as a sort of bag-net, of which the upper jaw serves as the lid. The young are fed by the female, which, pressing her well-filled pouch against her breast, opens her mouth and allows them to take their fill therefrom.

Pelicans display great sagacity when fishing, a flock often combining to form a horseshoe, and, driving the fish into a mass, take their fill. This method, of course, is only possible when fishing in the estuaries of rivers or lakes, where the fish can be "rounded up," so to speak. Clumsy as the pelican looks, it is yet capable of wonderful powers of flight; indeed, it shares the honour with the vultures, storks, and adjutants as an expert in the peculiar form of flight known as "soaring."

A North American species of pelican is remarkable in that during the breeding-season the beak is ornamented with a peculiar horny excrescence, which is shed as soon as that period is over.

Pelicans are natives of the tropical and temperate regions of the Old and New Worlds, and live in flocks often numbering many thousands. The nest is placed on the ground, and therein are deposited two white eggs. The young are helpless for some time after hatching.

In all some six-and-thirty species of CORMORANTS are known to science, of which two are commonly to be met with round the British coasts, one of which also travels inland to establish itself on such lakes and rivers as may afford it support.

In various parts of the world cormorants are taken when young and trained to catch fish: sometimes for sport, or--as in China--to furnish a livelihood for their owners. At one time the Master of the Cormorants was one of the officers in the Royal Household of England, the post having been created in 1611 by James I. The method of hunting is as follows:--After fastening a ring around the neck, the bird is cast off into the water, and, diving immediately, makes its way beneath the surface with incredible speed, and, seizing one fish after another, rises in a short space of time with its mouth full and throat distended by the fish, which it has been unable to swallow by reason of the restraining ring. With these captures it dutifully returns to its keeper, who deftly removes the fish, and either returns the bird to the water, or, giving it a share of the spoil, restores it to its perch.

Cormorants nest either in trees or on the ground; they lay from four to six eggs, and the young feed themselves by thrusting their heads far down the parents' throats and helping themselves to the half-digested fish which they find there.

The cormorant has a certain sinister appearance equalled by no other bird, so that its introduction in Milton's "Paradise Lost" (Book IV., 194) seems particularly appropriate. Satan, it will be remembered, is likened to a cormorant:--

So clomb this first grand Thief into God's fold . . . . . . . Thence up he flew, and in the Tree of Life, The middle tree and highest there that grew, Sat like a cormorant.

The curious bottle-green plumage, green eyes, long hooked beak, and head surmounted by a crest of the smaller sea-loving representative of the two British species were doubtless familiar enough to Milton before blindness overtook him.

Some of our readers may have made the acquaintance of the cormorant's nearest ally, the DARTER, or SNAKE-NECK, in the Fish-house at the Zoological Gardens of London. For the sake of those who have not, we may say that the darter may be described as a long-necked cormorant, with somewhat lighter plumage. The head is small and flat, and armed with a pointed, dagger-like bill, whose edges are finely toothed, with needle-like points projecting backwards. The neck is very long and slender; hence its name of Snake-neck. Furthermore, it is remarkable for a very strange "kink," formed by a peculiar arrangement of the neck-bones--an arrangement intimately associated with its peculiar method of capturing its prey, which, as with the cormorant, is pursued under water. How dexterously this is done may be seen any day in the Fish-house at the Zoological Gardens, where, as we have already mentioned, these birds are kept. At feeding-time they are turned loose into a large tank into which a number of small fish have been placed. The birds dive as soon as they reach the water, and with surprising speed chase their prey till within short range. Then, by a sudden bayonet-like lunge, made possible by the peculiar "kink" in the neck, a victim is transfixed, brought to the surface, released from the bill by a series of sudden jerks, tossed into the air, and dexterously caught and swallowed.

The darter is found in Africa, India, the Malay region, Australia, and South America, frequenting the banks of rivers, lakes, and swamps, sometimes singly, sometimes in pairs or in immense flocks.

Very different from either of the foregoing species, both in build and coloration, is the GANNET. In its habits it is also different. The adult bird is about the size of a goose, white in colour, and armed with a powerful pointed bill. The young have a quite distinct plumage, being deep brown, speckled with white, this livery being worn for nearly three years.

The greater part of a gannet's lifetime seems to be spent upon the wing, a fact which implies a very different method of feeding from that followed by the cormorant and darter; and this is actually the case. Preying upon shoals of herring, mackerel, sprats, or pilchards, the birds, flying singly or in flocks, as soon as the fish are discovered, rise, soar in circles to such a height as experience shows best calculated to carry them by a downward motion to the required depth, and then, partially closing the wings, plunge upon their prey, and rarely without success, the time which elapses between the plunge and the immersion being about fifteen seconds. A flock of gannets feeding is a really wonderful sight, and can be witnessed in many places around the British coasts, for the gannet is one of the very common British birds. The pilchard-fishermen off the Cornish coast learn when the shoals are at hand, and the direction in which they are travelling, by the actions of these birds. A very cruel experiment is sometimes practised upon the gannet, based upon its well-known method of fishing. A herring is tied to a beam and set adrift, and the bird, not noticing the trap, plunges with its usual velocity upon the fish, with the result that it is killed instantly by the shock of the contact.

Gannets breed in colonies of thousands on the islands off the east and west coasts of Scotland. They lay but a single egg, in a nest composed of seaweed deposited in inaccessible crags of precipitous cliffs. The young are at first naked; later they become clothed with long white down. "At one time," says Mr. Howard Saunders, "young gannets were much esteemed as food, from 1,500 to 2,000 being taken in a season during the month of August. They are hooked up, killed, and flung into the sea, where a boat is waiting to pick up the bodies. These are plucked, cleaned, and half roasted, after which they are sold at from eightpence to a shilling each.... The fat is boiled down into oil, and the feathers, after being well baked, are used for stuffing beds, about a hundred birds producing a stone of feathers."

Gannets present one or two structural peculiarities of sufficient interest to mention here. In most birds, it will be remembered, the nostrils open on each side of the beak; but in the gannet no trace of true nostrils remains; and the same may almost be said of the cormorant and darter. In gannets, however, a slight indication of their sometime existence remains, though the nostril itself no longer serves as an air-passage; and these birds are compelled to breathe through the mouth. Again, the tongue, like the nostrils, has also been reduced to a mere vestige. Stranger still is the fact that immediately under the skin there lies an extensive system of air-cells of large size, which can be inflated or emptied at will. Many of these cells dip down between the muscles of the body, so that the whole organism is pervaded with air-cells, all of which are in connection with the lungs.

The FRIGATE- and TROPIC-BIRDS, which now remain to be described, are probably much less familiar to our readers than the foregoing species.

FRIGATE-BIRDS are remarkable in more ways than one. To begin with, their general appearance may be described as that of a small, long-winged, fork-tailed albatross, mounted upon particularly diminutive legs, so short as to do little more than raise the body off the ground. Their flight is wonderfully graceful, and capable of being sustained for considerable periods; for, like the gannets, they pass most of their time on the wing. They feed upon surface-fish, which they capture from the surface of the water without alighting, or upon fish which they take from the gannets of the neighbourhood.

Frigate-birds build their nests in trees, on low bushes, or on the ground, and sometimes upon ledges of precipitous cliffs. The nest is a loose structure composed of sticks, and its construction is accompanied by much pilfering from one another. Only a single egg is laid.

About the beginning of January the male acquires a very remarkable pouch of brilliant scarlet skin, which hangs beneath the beak. Frigate-birds are found all over the world within the tropics.

The TROPIC-BIRDS, or BOATSWAIN-BIRDS, as they are sometimes called, are more like gulls or the heavier species of terns in general appearance, and in no way resemble superficially the forms with which they are associated, save in the fact that all the toes are enclosed in the same web. A study of their anatomy, however, leaves little doubt that these birds are really members of the Pelican Tribe.

Either pure white, relieved with black, or of a beautiful apricot-yellow, with similar black markings, with a powerful bill and long tapering tail, the tropic-bird is one of the most beautiful of sea-birds. There are altogether about six species of tropic-birds, distributed over the Pacific and Indian Oceans. They nest in hollows of cliffs or holes in trees, and lay a single egg, which bears some resemblance to that of a kestrel.
