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,[Pg 87] 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.
The CRANES (Grues) constitute by far the largest, best formed, and most intelligent division of the above birds, and are characterised by their almost conical body, long thin neck, small, beautifully-shaped head, and sharp, moderately strong beak, which is straight and slightly compressed at its sides and blunt at the culmen, about as long as the head, soft at its base, and hard at the tip. The long powerful legs are bare, and the feet are furnished with four toes; of these the hinder toe is so small as not to touch the ground; the exterior and centre toes are connected by skin as far as the first joints; the claws are short, blunt, and flatly curved, the wings large and broad, with the third quill longer than the rest and the upper secondaries much prolonged; the short tail is usually rounded, and the thick plumage composed of small feathers; in some species the head and neck are bare, in others adorned with beautiful plumes. The sexes are similar in their coloration, but differ much in size; the young resemble the adult bird after the first moulting, but only attain the flowing crest at a later period.[Pg 88]
THE SUN BITTERN, OR PEACOCK HERON (Eurypyga helias). ONE-FOURTH NATURAL SIZE.
Cranes are met with in almost every portion of the globe, but are especially numerous in its warmer regions; such as inhabit northern latitudes migrate as far as, but do not breed in the countries near the equator. Marshy localities or morasses, in the vicinity of cultivated land, are the situations they prefer, as affording a rich and constant supply of the frogs, molluscs, worms, and vegetable diet upon which they subsist. In Palestine the Cranes visit the cultivated districts only in the time of their spring migrations, when but a few pairs remain in the marshy plains, while the greater number pass on to the north. In the Southern Wilderness they resort in immense numbers to certain favourite roosting-places during the winter. Towards evening at this season, we are told that clouds of these enormous birds literally darken the air. Their roosting-place, according to Dr. Tristram, is usually a gently-sloping, isolated knoll, where no ambush is possible, and where they can keep a good look-out on all sides. In such situations their whooping and trumpeting cry is to be heard through the entire night. The following interesting particulars respecting the migrations of these birds in the Wilderness of Sinai are from the notes of the Rev. F. W. Holland:—"On March the 22nd we saw an immense flock of Cranes crossing the Red Sea from Africa. The line appeared to stretch across the whole breadth of the sea. Five days afterwards we found a solitary one amongst the mountains, which did not attempt to fly, but stalked majestically on before our camels, quite regardless of a few revolver bullets whizzing close past him. At last an Arab boy gave chase, and running him into a bush soon caught him, and returned in triumph, holding him up by the tips of his wings. When released he stalked on as unconcernedly as before; but when on the point of being caught again, the strange bird suddenly took wing, and after wheeling round several times flew away over the mountains. On the 13th of April, three days south of Beersheba, in the desert, another large flock of more than two[Pg 89] thousand Cranes passed over our heads, all going north as the others. In the beginning of May, several smaller flocks were seen crossing the same desert from Akabah towards Suez."
THE COMMON CRANE.
The COMMON CRANE (Grus cinerea) is recognisable by its partially bare head, and the long curly feathers on its upper wing-covers. In this bird the plumage is principally ash-grey, black in the region of the throat and brow, and whitish on the side of the neck; the quills are black, the eyes brownish red, and the feet blackish; the beak is reddish at its base, and blackish green at its tip. This species is four feet and a half long, and seven and three-quarters broad; the wing measures twenty-five and the tail eight inches in length.
