insects; now it flies into a tree or bush, where it pursues its search for insects or pours forth its joyous song. Nor does it confine its operations to trees, bushes, and dry land. I have seen a magpie-robin hunting for insects on a tangled mass of weeds and stems floating on water. On these it hopped about just as it does on terra firma. Each little jump caused considerable commotion in the water. The bird did not seem to mind its toes getting wet.

The dhayal is essentially a bird of gardens. Like the English robin, it prefers to dwell as near human habitations as possible. In my opinion it is one of the finest song birds in the world. Like the majority of melodious birds, the magpie-robin is not in song all the year round. During the early winter it is a silent creature. Towards the end of the cold weather the cock begins to find his voice, and at that time his efforts are not very pleasing to the human ear. But each successive day’s effort produces better results, until, by March, the bird is able to pour forth a torrent of far-reaching melody which is inferior to that of no Indian bird save his cousin, the shama.

Needless to say, the period when the cock dhayal is in song corresponds to the mating time. At this season the cocks are very pugnacious. This pugnacity is simply the expression of the fact that the dhayal is at that time more than usually overflowing with energy. This energy has to find outlets. One of these is through the medium of vigorous song. Another way of dissipating energy is by performing gymnastic feats in the air. As a rule magpie-robins rarely perform sustained flights. They are content with flitting from bush to bush, or making little excursions to the ground and back again. But at the breeding season the cocks often fly up high in the air and describe a series of wide circles. They will spend hours in this performance with only a few seconds’ rest at long intervals.

The eggs are nearly always placed in some natural hole, that is to say, one not excavated by the dhayal itself. The hole is sometimes in a tree, but nine times out of ten in Northern India the site selected is a hole in some building. The servants’ quarters in the corner of some shady garden are almost invariably chosen. A very favourite spot is between the wooden lintel and the mud wall of a kachcha building; such buildings are well called kachcha, for they begin to crack and fall down as soon as they are built. The cracks and crevices that appear in them offer just what magpie-robins want for nesting purposes. The eggs are not laid on the bare brick, mud, or other material in which the cavity exists. The hole is invariably lined with roots, fibres, grass, feathers, or any other soft material available. My experience of the nests of this species has been confined chiefly to Northern India, and I do not recollect ever having found a nest that was not in the wall of some building; but observers from South India say that, as often as not, the dhayal nests in trees.[1] Oates states that in Burma the magpie-robin almost invariably selects a large hollow bamboo, and places its nest about two feet inside, near the first joint; but he adds that the bamboos selected are generally to be found lying about the verandahs and cucumber framings of the native houses. The truth of the matter would seem to be that magpie-robins select the very first cavity of the right size they come across, and, as they affect human habitations, the cavity used is almost invariably near some man’s dwelling. In Northern India the construction of the dwellings of Indians is such that the walls afford convenient sites, so that these are generally utilised; in other parts of the country, where the walls do not present so many holes, other cavities in trees, etc., are selected.

The eggs have a greenish-white background which is usually largely obliterated by blotches of brownish red. March, April, May, and June are the months in which eggs are most likely to be found; April and May for preference.

THE INDIAN SNAKE-BIRD

The Indian darter, or snake-bird (Plotus melanogaster) is best described by what I may perhaps call the synthetic method. Take a large cormorant and remove the head and neck; to the headless cormorant, sew on the head and neck of a heron, and you will have produced a very fair imitation of the Indian snake-bird. If during the operation you happen to have dislocated one of the lower neck vertebrae of the heron, so much the better, for the slender neck of the darter is characterised by a bend at the junction of the eighth and ninth vertebrae, which, as Mr. Garrod has shown, enables the bird, by suddenly straightening the neck, to transfix the fish on which it has designs. As a catcher of fish the snake-bird is probably without peer. This is not surprising, since it possesses the swimming and diving apparatus of the cormorant, the long neck and dagger-like beak of the heron, and, in addition, a patent thrusting apparatus in the shape of the aforesaid kink in the neck.

The Indian darter is a bird with which all who go down to jhils to shoot duck must be familiar, since it is a full yard in length and occurs in most parts of India, Burma, and Ceylon. Notwithstanding its large size, it is apt to be overlooked when in the water, because it almost invariably swims with the body submerged, showing only the upper neck above the surface. Every now and again it completely disappears from view. After remaining submerged for several seconds the head reappears with a small fish projecting from the bill. The fish is forthwith thrown a little way into the air, and then caught and swallowed. This habit of tossing food into the air preparatory to swallowing it occurs in many long-billed species, and appears to be the most expeditious method of getting food from the tip of an elongated beak to the other extremity, where it is seized by the muscular walls of the gullet and passed onwards.

The snake-bird is said sometimes to secure its quarry by diving from a perch like a kingfisher. I have not observed the bird behave thus, and the method does not appear to be generally practised.

Plotus melanogaster is called the snake-bird because of its long, slender, snake-like neck, which looks very like the anterior portion of a water-snake when the bird swims, as it often does, with the body submerged. If danger threatens the bird usually sinks in the water until every part of it except the beak disappears. This certainly is a method of hiding superior to that said to be adopted by the ostrich.

The snake-bird is a rapid swimmer, and as it frequently remains under water for thirteen or fourteen seconds at a time, it is able to move considerable distances while completely submerged.

The snake-bird is a powerful flier. While on the wing it does not retract its neck after the manner of the heron, but progresses with neck extended. The neck being so slender gives the bird a comic appearance and renders it easy to identify during flight. When resting
