XXXI THE LARGEST BIRD IN INDIA

Previous

It has always been a cause of wonder and sorrow to me that the sarus crane (Grus antigone) does not occur in the neighbourhood of Madras, or indeed in South India at all. The tropical portion of the Indian peninsula, with its millions of acres of green paddy, should be a paradise for cranes; yet not one of these fine birds is likely to be found south of the Godavery, or, at any rate, of the Kistna. There is presumably some good reason for this, but that reason has yet to be discovered.

The sarus might well be called the Indian crane, for it is one of the most characteristic and beautiful birds of Northern India; moreover, it appears to be found nowhere outside India. Saruses occur in Burma, but the Burmese birds have fallen into the hands of the ornithological systematist, and he has, of course, made a separate species of them. The sarus from Burma is now known in the scientific world as Grus sharpii—not because very sharp eyes are necessary in order to distinguish him from the Indian form!

The plumage of the sarus is a beautiful shade of grey. The tail feathers are paler than the rest of the plumage, being almost white in some individuals. There is a broad red band round the neck and the lower part of the head. This at the breeding season becomes very brilliant, and then looks like a broad collar of crimson velvet. The legs of the sarus are also bright red and are nearly a yard long. So that the sarus can, when he wishes to assert himself, look over the head of the average human being without unduly stretching his neck.

The sarus is the only crane that stays in India throughout the year. As has already been said, the species is very common in Northern India; indeed, a broad stretch of landscape in that part of the world would not seem true to life did it not contain a pair of saruses standing near together. Every pair of these birds is a regular Darby and Joan. There are instances on record of a sarus having pined away and died because it had lost its mate. This affection of the male and female who pair for life is so notorious that the Indians who eat the flesh of these birds make a point, after they have bagged one of a pair, of killing the mate.

The food of saruses is, as Hume remarks, very varied. No small reptile or amphibian comes amiss to them. They also eat insects and snails, and seeds and green vegetable matter. They are often to be observed feeding at some distance from water. Indeed, my experience is that they are seen more often on dry land than in water. Their long legs appear to be of little use to them except at the nesting season, when they are necessary in order to enable the birds to wade to the nest. Cranes, unlike storks and herons, cannot grip with the foot, so that they never perch in trees. The nest is built on the ground and, presumably for the sake of protection against jackals, wolves, and such-like creatures, is usually surrounded by water. As a rule, it is not constructed on an island, but is itself an islet rising from the bottom of the jhil or tank in which it is situated.

I have not had the good fortune to witness a nest of the sarus in course of construction, but from the behaviour of the owners when heavy rain falls after the nest is completed, I believe that both sexes take part in construction. As the nesting season is in June, July, August, and September, a good deal of rain usually falls while nesting operations are going on. The nest is a mound or cone, composed of rushes and reeds, of which the diameter is two feet at least. The top of this cone, on which the eggs are placed, is usually about a foot above the surface of the water. Thus the eggs lie only a little above the water level; nevertheless, they always feel quite dry, as does the layer of rushes on which they are placed. This is rather surprising—one would expect the water to get soaked up into the parts of the nest above the surface; but this does not happen. It is needless to say that if the top of the nest became submerged it would be impossible to keep the eggs dry; hence, when very heavy rain causes the water level round the nest to rise, the parent saruses raise the top of the nest by adding more material to it.

Two eggs are usually laid. These, as befits the size of the owners, are very large. It is as much as one can do to make both ends meet of a tape eleven inches long, passed round the long axis of the egg. The eggs vary considerably in size, but are usually of a creamy hue, They may be with or without markings. The shell is very thick and hard, so that if sarus’s eggs were used for electioneering purposes, fatalities would often occur.

Various observers give very different accounts of the behaviour of the parent saruses when their nest is attacked. The general experience is that they show no fight, but that they retire gracefully as soon as the human being gets within twenty yards of the nest. Hume, however, records one case of a sitting sarus making such vigorous pokes and drives at the man who approached her when sitting on the nest that he was forced to flap her in the face vigorously with his waist cloth before she left her eggs. That, says Hume, is the nearest approach to a fight for its penates he has ever seen a sarus make. Recently I visited a nest of these birds, which was situated in a small patch of water, perhaps forty feet square, with a millet field on one side and paddy on the other three. I was on horseback, not wishing to wade nearly to my waist. With me were three men. When we first noticed the nest, the hen was sitting on it and the cock standing near by. As we approached the female rose to her feet very slowly, and then I could see that the nest contained a young one. When we were at a distance of some ten yards the female began to move her feet as if scraping the nest, and the young bird betook itself quietly to the water, and swam slowly into the neighbouring flooded paddy field. The hen then slowly descended from the nest into the water and quietly walked off. On reaching the nest, I found in it one egg. I sent one of the men after the youngster, which he quickly secured and brought to me to look at. It was about the size of a small bazaar fowl, and had perhaps been hatched three days. It was covered with soft down. The down on the upper parts was of a rich reddish fawn colour, the back of the neck, a band along the backbone, and a strip on each wing being the places where the colour was most intense; these were almost chestnut in hue. The lower parts were of a cream colour, into which the reddish fawn merged gradually at the sides of the body. The eyes were large and black. The bill was of pink hue and broad at the base where the yellow lining of the mouth showed. The pink of the bill was most pronounced towards the base, fading almost to white at the tip. The legs and feet were pale pink, the toes being slightly webbed. Even at that stage of the youngster’s existence the legs were long, and enabled him to swim with ease, but they were not strong enough to support him when he tried to walk. Sarus cranes cannot walk properly until they are several months old.

While I was handling the young bird the cock sarus was evidently summoning up his courage, for presently he began to advance in battle array, that is to say, with neck bent, so that the head projected forward, mouth slightly open, and wings about half expanded. Thus he slowly approached, looking very handsome. He did not advance direct, but took a circuitous course as if stalking us. When he had approached within about six feet I made a pretence of striking him with a short cane. Of this act of hostility he took not the least notice, but continued to approach. The men with me, who were on foot, began to fear being attacked, so one of them pulled up some paddy stalks and threw these at him. This made him jump and retreat a few paces. But he soon recommenced his advance in battle array. Then one of the men rushed at him. That caused him to retreat a few paces hastily, but with dignity. He then proceeded to attempt a rear attack, and as he circled round us with bent neck he put me in mind of the villain of the melodrama, who stalks about saying “My time will come!” When the sarus had advanced thus to within four feet of my men and looked as though he were about to spring at them, one of these lunged at him with a short stick, and he would have been struck had he not beaten a hasty retreat. Nothing daunted, he again returned to the attack. We were at the nest for fully ten minutes, and the whole time he was trying to get at us. Only once did he utter his trumpet-like call. The female meanwhile remained watching at a distance of perhaps forty yards.

Having seen what we wanted, we replaced the young bird and the egg in the nest and retreated fifteen or twenty yards. We waited to see what the parent birds would do. The female came up to the cock (she is distinguishable by her smaller size); then they both advanced very slowly towards the nest, the hen approaching the faster. When at a distance of perhaps eight yards from the nest, the cock indulged in some curious antics. He slowly drew himself up to his full height and stood thus motionless for a few seconds, then he stretched out his bill towards the sky. Next, the long neck began to bend slowly until it took roughly the shape of the letter S. Then, while the neck was still so bent, the sarus dipped his bill into the water. After this he again stood upright and repeated the whole performance. Finally he indulged in a little dance. Meanwhile the hen slowly advanced, and when within a yard of the nest stood still and contemplated it for a little, then, after caressing the youngster with her bill, she slowly climbed on to the nest. The nest cavity being a very shallow one, the young bird sitting in it could be seen from a considerable distance, and its reddish fawn plumage showed up in strong contrast to its surroundings. The sarus nestling cannot by any stretch of the imagination be called protectively coloured, but it fares very well, notwithstanding its conspicuousness, because its parents never depart far from the nest, and while they are present it is immune from attack. Even large birds of prey avoid the powerful beak of an infuriated crane.
