BUPHUS COMATA ____ SQUACCO HERON

(about ½ Nat. size)]

* * * * *

The WHITE HERONS (Herodias) possess a slender body, long neck, and a comparatively weak bill. Their pure white plumage is adorned with long streaming feathers on the back during the period of incubation.

THE GREAT WHITE HERON.

The GREAT WHITE HERON (Herodias alba) has the entire plumage of pure and dazzling white. The eye is yellow, and the beak dark yellow; the bare cheeks are greenish yellow, and the feet dark grey. This species is forty inches long and seventy-two broad; the wing measures twenty-one inches, and the tail seven inches and a half. The beak changes colour, not according to the age of the bird, but at different seasons of the year. The young do not exhibit the streaming feathers on the back. This Heron inhabits the southern parts of Siberia and South-eastern Europe, and during its migrations appears in South Asia and North Africa. In India, and South and Western Africa, it is replaced by a very similar species. In England it is occasionally but rarely seen. Like its congeners, this beautiful bird occupies marshy ground in the vicinity of water, preferring such spots as are least frequented by man, and subsists upon the same fare as other members of its family. In its general air and movements, however, it differs from them in many respects; it walks with a more stately step, flies faster and more gracefully, and constantly assumes a variety of strange postures; when standing, it frequently buries its head, neck, and one leg in its plumage, and thus presents the appearance of a great white ball fastened to the top of a thin stick. The large nest of this bird is placed amongst reeds, of portions of which it is also built; so firm and strong are these heaps that, as we are told, they can support the weight of a man. The eggs are usually three or four in number, and have a smoother shell and bluer tint than those of the species before described.

THE LESSER EGRET.

The LESSER EGRET (Herodias garzetta) resembles the above bird in its general appearance and habits, but it is not more than twenty-four inches long and forty-two broad; the wing measures twelve and the tail four inches. In this species the eye is bright red, the beak black, and the foot black, with greenish yellow joints. This beautiful little Egret occupies the same latitudes as the larger species, and, according to Layard, has been procured both in winter and nuptial dress in the vicinity of Cape Town; also at Colesberg, and at the Kneysna. The stomachs examined by that naturalist contained multitudes of small aquatic shells. A nearly-allied species (Ardea egretta) is common on the Kneysna, but is so shy as to be almost unapproachable; it breeds on a small rock on the sea.

The Little Egret is now very rare in Great Britain, but was formerly much more common, and was regarded by our forefathers as a dainty article of food. In the celebrated feast on the enthronisation of Archbishop Nevill no less than 1,000 Egrets are mentioned in the bill of fare.

THE CATTLE HERON.

The CATTLE HERON (Bubulcus ibis) represents a group recognisable by their compact form, short neck, short powerful beak, short legs, and the hair-like development of some of their feathers. The plumage is pure white during the breeding season, adorned with long, flowing, rust-red feathers on the crown, upper breast, and back. The eyes are light yellow, the bridles and eyelids greenish yellow, the beak is orange, and the foot of the adult bird reddish yellow; that of the young is of a brownish shade. The male is nineteen inches long and thirty-four broad; the wing measures nine inches and a quarter, and the tail three inches and a quarter; the female is not quite so large. This species is extremely common in Egypt, where, unlike other Herons, it frequents inhabited districts, preferring inundated fields, and only occasionally visiting the banks of lakes or streams. In Egypt it is constantly seen following the buffaloes and cattle, or inspecting their backs, in search of insects or grubs; and in Eastern Soudan accompanying droves of elephants for the same purpose. We have been told, on reliable authority, that as many as twenty of these birds are sometimes seen upon a single elephant. With the natives they live on most excellent terms, and carry on their acceptable work quite regardless of their presence. Such of these birds as inhabit Egypt commence breeding when the Nile rises, while those dwelling in Eastern Soudan lay somewhat earlier in the year. The nests are built close together upon trees, and are constantly seen close to the huts of the natives. The eggs, from three to five in number, are oval in form, and have a greenish blue shell.

THE NIGHT HERON.

The NIGHT HERON (Nycticorax Europæus) has a compact body, short, thick, broad beak, curved at its culmen, moderately high legs, broad wings, and thick plumage, which, unlike that of the members of the family already described, has but three of its feathers unusually prolonged; these are slender, and placed on the back of the head. In the adult bird, the crown, nape, upper part of the back, and shoulders are greenish black, the rest of the mantle and sides of the throat dark grey; the feathers on the under side are pale straw-yellow, and the three long crest-feathers either quite white or white and black. The eye is of a rich purple, the beak black with yellow base, the bare patch on the head green, and the foot greenish yellow. In the young, the mantle is brown, spotted with brownish yellow and yellowish white; the throat yellow, and belly white, spotted with brown; the eyebrows are brown, and the head without crest. This species is from twenty-one to twenty-two inches long, and forty-four broad; the wing measures twelve inches and a half, and the tail four inches and a quarter.

The Night Heron is extremely common in Holland in the summer, and is also met with in Germany, Italy, the south of France, and Spain; occasionally, but very rarely, it has been shot in Great Britain. It visits Africa during the winter, and is found far in the interior of that continent. In northern latitudes it appears about the end of April, and leaves again in September or October. The Night Herons both sleep and breed upon trees, and therefore principally frequent well-wooded localities, whether these be in the vicinity of water or not; in moist, well-planted regions, however, they are especially numerous. Except during the breeding season they sleep, or at any rate remain quiet, throughout the entire day, and only descend at twilight from their perches in order to seek for food. Upon the ground they progress slowly, with short steps, but move in the air with comparative swiftness, alternating an easy gliding motion with rapid but noiseless strokes of the wings. In places where these birds abound, they are often seen flying together in very large flocks, at a considerable height, on their way to a suitable hunting-ground, over which they generally hover before alighting. Among the branches they climb with an agility that is not exceeded by any member of the family. Their voice is extremely harsh, and somewhat resembles the discordant croak of the Raven. The Night Herons breed from May to July, and usually form regular settlements not only of their own species, but with many allied birds. The large, carelessly-constructed nest is placed high on trees, and contains four or five oval green eggs of very various shades. The female broods, whilst her mate mounts guard quietly perched by her side, or quarrels with and teases other males in his neighbourhood.

The Great Night Heron of America, which is considered by Audubon and others as a distinct species, is seen as far as the northern and eastern extremities of the United States, but is unknown farther northwards. In the winter it goes as far as the tropics. These birds arrive in Pennsylvania in April, and immediately take possession of their old nurseries, usually in the depths of a cedar swamp, or of some inundated and inaccessible grove of oaks; there they pass the day till twilight comes, and then the parent birds sally forth to the sea-shores and marshes in search of food for themselves and young, proceeding in marshalled ranks, and uttering from time to time a guttural "kwah," in a hollow voice, that resembles the sound of a person vomiting. The eyries of the "Kwah" birds have been occupied from remote times by eighty or one hundred pairs, and when the trees are felled, they only remove to another part of the same swamp.

The BITTERNS (Ardetta) are recognisable by their comparatively small size, slender bill, low feathered tarsi, their short wings, in which the second quill is longer than the rest, and weak short tail. The plumage, which is by no means striking in its coloration, varies in hue according to the age and sex of the bird.

THE LITTLE BITTERN.

The LITTLE BITTERN (Ardetta minuta) is from fourteen to sixteen inches long, and from twenty-one to twenty-three broad; the wing measures five inches and three-quarters, and the tail two inches. This elegant bird is of a glossy blackish green on the crown, nape, back, and shoulders; the upper wing and under side are reddish yellow, spotted with black on the side of the breast; the quills and tail-feathers are black; the eye and bridles yellow. The pale yellow beak is brown at its culmen; and the foot greenish yellow. In the female all the dark parts are brownish black, and the light portions of the plumage pale yellow; the young have the crown and nape reddish brown, striped with a deeper shade, the under side spotted brown and reddish yellow, and lower belly and tail-covers white. The Little Bittern is only a summer visitor to Great Britain. It frequents marshes, osier holts, and other places in the neighbourhood of water, feeding on such small animal food as is there easily obtained.

The COMMON BITTERN (Botaurus stellaris) is the representative of a group having a compact body, long thin neck, a narrow high beak, large-toed feet, broad wings, a tail composed of ten feathers, and thick plumage, which is slightly prolonged on the neck. The sexes only differ in their size. In both the crown is black, the nape greyish black, mixed with yellow, and the rest of the plumage spotted and streaked with dark brown of various shades; the throat exhibits three stripes; the eye is bright yellow, and the bare portion around it greyish green; the upper mandible is brownish grey, and the lower one of greenish hue; the foot is light green, with yellow joints. This bird is twenty-eight inches long and forty-eight broad. The wing measures fifteen and the tail five inches. The nest is placed in marshes, among reeds. The eggs are five in number, of an olive colour. Its food consists principally of fish and reptiles of various kinds. During the breeding season it utters a loud bellowing noise, and for this cause it probably received the generic name of Botaurus. "This bellowing noise", says Latham, "is supposed to arise from a loose membrane, which can be filled with air and exploded at pleasure. The situation of it is at the divarication of the windpipe. It is capable of great distension, and is probably the cause of this singular phenomenon, observed, we believe, in no other bird, at least in the same degree." At other times the bird makes a sharp harsh cry on rising, not unlike that of a Wild Goose.

THE SUN BITTERN, OR PEACOCK HERON.

The SUN BITTERN, or PEACOCK HERON (Eurypyga helias), represents a group of South American birds, having a small meagre body, long thin neck, a head resembling that of a Heron, and a long, straight, hard-pointed, and powerful beak, compressed at its sides, and slightly arched at its culmen. The high slender foot has the hinder toe moderately developed; and the large broad wing has its third quill longer than the rest; the remarkably long tail is composed of broad feathers. The rich, lax, and variegated plumage is black upon the head and nape; the eyebrows, a line that passes from the corner of the mouth to the nape, the chin, and throat are all white; the feathers on the back and shoulders, and the upper secondaries are black, striped with brownish red; the feathers on the rump and upper tail-covers are black and white; those on the neck striped black and white; and those on the under side yellowish or brownish white; the quills are light grey, veined with black and white, and striped with brown; the tail is similarly coloured, but is broadly marked with a black stripe, edged on one side with brown. Slight variations from the above colours and markings are often observable. The eye is red, the beak yellow, and the foot straw-colour. This species is about sixteen inches long.

This beautiful bird is a native of the northern parts of South America, and is met with on the coast and river-banks from Guiana to Peru, and from Ecuador to the Province of Goyas, in Brazil. Upon the shores of the Orinoco and Amazon it is especially numerous. We are told by travellers that among all the gorgeously-coloured inhabitants of these luxuriant regions, the Peacock Heron is conspicuous, presenting as it does a most brilliant combination of yellow, green, black, brown, and grey, when seen by the full light of the sun, in whose rays it delights to bask, keeping meanwhile its wings and tail gracefully outspread. In Para, in Northern Brazil, says Bates, "the banks at the edge of the water are clothed with mangrove bushes, and beneath them the muddy banks, into which the long roots that hang down from the fruit before it leaves the branches strike their fibres, swarm with crabs. On the lower branches the beautiful Ardea Eurypyga helias is found. This is a small Heron, of exquisitely graceful shape and mien; its plumage is minutely variegated with bars and spots of many colours, like the wings of certain kinds of moths. It is difficult to see the bird in the woods, on account of its sombre colours and the shadiness of its dwelling-places; but its note, a soft, long-drawn whistle, often betrays its hiding-place. I was told by the Indians that it builds on trees, and that the nest, which is made of clay, is beautifully constructed. It is a favourite pet-bird of the Brazilians, who call it Pavaõ (pronounced 'Pavaong'), or Peacock. I often had opportunities of observing its habits. It soon becomes tame, and walks about the floors of houses, picking up scraps of food, or catching insects, which it secures by walking gently to the place where they settle, and spearing them with its long slender beak. It allows itself to be handled by children, and will answer to its name 'Pavaõ! Pavaõ!' walking up with a dainty, circumspect gait, and taking a fly or beetle from the hand." According to Castelnau, in its wild state the Sun Bittern is by no means so amiable, but if molested, springs upon its enemy as a cat does upon a mouse, beating the air meanwhile with its wings.

For further particulars respecting the habits of this beautiful species, we are indebted to observations made on birds that have been successfully reared in the Zoological Gardens of London and Amsterdam. A pair of Peacock Herons purchased in 1862 by the London Zoological Society, in 1865 showed symptoms of a desire to breed. According to Mr. Bartlett, whom we have to thank for the following interesting particulars, early in May they commenced carrying bits of grass, sticks, and such-like scraps, and were constantly walking round their pond, evidently in search of materials to compose a nest, and appeared to try to mix wet dirt with bits of moss. This proceeding suggested the idea of supplying them with wet clay and mud, which they at once employed. After a short time, they decided to make their nest on the top of a pole or tree about ten feet from the ground, on which was fixed an old straw nest. Both birds carried up mud and clay, mixed with bits of straw and grass-roots, in order to form the outer wall, and plastered the inside thickly with a coating of mud. Shortly after the nest was completed a broken egg was found, and in the early part of June another was laid; both parents took their turn in the work of incubation, and hatched the young bird on the 9th of July. It was covered with fine short down, and closely resembled a young Plover or Snipe in its general appearance. It remained in the nest, and was fed with small live fishes and insects, and did not gape or cry, but as soon as the parents appeared with food, it pecked the morsels from them, and swallowed them. It left the nest in twenty-one days, its wings being strong enough to bear it to the ground, where it was fed as before, and never returned to the nest; it grew very rapidly, and in two months' time was not distinguishable from the adults. Early in August the old birds began to repair the nest, adding a fresh lining of mud and clay; and at the end of the month the female laid another egg. This time the male attended more to the duties of incubation than his partner, who devoted her principal attention to feeding her now full-grown offspring. The second young bird was hatched on the 28th of September, but received such slight attention from its parents that the keeper feared it might starve from their neglect, and he therefore determined to go up by a ladder and feed it. The hungry little fellow took the food readily from his hand, and was thus reared till it arrived at maturity.

The MARSH-WADERS (Paludicolæ) comprise so great a variety of species as to render a general description of their characteristics extremely difficult. In these birds the body is powerful, the neck of moderate size, the head small, the beak round and straight, the legs long, and the feet furnished with four toes; the wings are of medium length, and the tail short. The thick plumage varies strikingly in its hues in old and young birds, and but little in the sexes. Most of the members of this group occupy moist or boggy localities, and pass their lives upon the ground, while some few frequent the branches of trees. Insects, small animals of various kinds, combined with vegetable diet, afford them the means of subsistence. The eggs are deposited in a nest, and have a spotted shell.
