Part 10
At midday, four hours after I had first seen the nest, I was astonished to find that it had assumed a saucer-like form. I was not a witness of the process whereby the original shapeless mass was made to take this shape, but my observations on other nests have convinced me that the nest is shaped entirely by the bird’s body and feet. When a bulbul brings material to the nest, it drops this on to what has already been collected, sits on it, and proceeds to arrange it with its feet, which work so vigorously as to shake the whole plant in which the nest is placed. In the middle of the process the bird usually turns on its axis, a right angle, and thus the interior of the nest becomes rounded by the bird’s breast. All new material is added to the inside of the nest.
At midday, then, the nest in question was a shallow saucer composed chiefly of Duranta and other twigs, dried grass, and bast. The leaves mentioned above had fallen some way below the nest, and the worsted and tissue paper had been crushed into a ball at one side of the nest.
By the evening more material, chiefly bast in bands about a quarter of an inch broad, had been added, and the nest looked almost as complete as some bulbuls’ nests in which I have seen eggs. But that particular pair were evidently bent on building a very substantial structure.
By 8 a.m. on the following day the cup of the nest had grown deeper, and its walls had been considerably thickened. By the evening of the day the nest was practically complete. On the 5th March the finishing touches were put to it in the shape of a few grasses and prickly stems.
The diameter of the completed nest is between 2½ and 3 inches. The nest is rarely quite circular. It is about 2½ inches in depth. The length of its diameter appears to be determined by that of the bird’s body (exclusive of head and tail) which is the mould that shapes it. A bulbul sitting in the nest looks very cramped and uncomfortable, with the tail projecting vertically upwards, the neck stretched out, and the chin resting on the rim of the nest. The crest of the sitting bird is folded right back.
On the early morning of the 8th March the first egg was laid. On the 9th a second egg was deposited. My little boy, to whom I had shown the nest, then thought that he would like a couple of bulbul’s eggs poached for his breakfast, so, regardless of the feelings of the bulbuls, removed both eggs and took them to the cook! As that individual declined to cook them, my little son replaced them, or rather one of them, for he broke the other. On the morning of the 10th a third egg was laid and deposited in the nest beside the other. The usual clutch of _Otocompsa emeria_ is three. On the morning of the 11th I found the nest half pulled down and empty and on the ground beneath I saw a few bulbul’s feathers. Some predaceous creature, possibly a cat or a mongoose, had seized the sitting bulbul in the night.
The above notes show that a pair of bulbuls can build a nest in a couple of days. This observation was confirmed by another pair who constructed a nest in my verandah on the 23rd and 24th March. On the 22nd I noticed a pair of bulbuls prospecting in a croton plant near my _daftar_ window; nevertheless, although I examined that plant carefully, I found no traces of a nest. On the next day, however, I saw that the nest had been commenced. During the three following days I had no leisure in which to look at the nest, but on the 28th I found a bulbul sitting on three eggs, so that, as only one egg per diem is laid, the first egg must have been deposited on the morning of the 26th at the latest.
On returning to my bungalow at about 10.30 p.m. of the 28th, I found some of the servants collected in the verandah. They showed me a dead brown tree snake (_Hipsas trigonata_) which they had killed in the plant containing the bulbuls’ nest. The reptile had evidently discovered the nest and crawled up the stem of the plant. At its approach the incubating bulbul had made a great commotion which attracted the notice of the servants. They promptly killed the snake. On my return the eggs were lying broken on the ground, and I was not able to discover whether the fluttering bulbul or the servants striking the snake had caused their downfall. No further eggs were laid. Bulbuls seem always to desert a nest when their eggs are destroyed. It is worthy of note that the snake attacked the nest in the dark, and on all other occasions on which I have observed similar tragedies they have been enacted at night. What, then, becomes of the elaborate theory of protective colouration?
XXIV NIGHTINGALES IN INDIA
The nightingale shares with the Taj Mahal the distinction of being an object on which every person lavishes high praise. All who hear the song of the nightingale go into ecstasies over it; similarly, every human being who sets eyes on the Taj waxes enthusiastic at the sight thereof. Some years ago a writer in the _Globe_ stated that a patient investigator compiled a list of nearly two hundred epithets bestowed by poets alone on the nightingale’s song, and I doubt not that an equally patient investigator could compile an equally long list of adjectives lavished on the Taj Mahal by those who have attempted to describe that famous tomb. The consequence is that every superlative in the English language has been appropriated by some person, so that he who nowadays wishes to bestow something original in the way of praise on either the nightingale or the Taj is at his wit’s end to know what to say. Recently I met in a railway train a Portuguese gentleman who was paying a visit to India. Needless to say, I asked him what he thought of the Taj. He promptly replied: “_Le Taj, ah! c’est un bijou._” I feel that by way of paying the necessary homage to the nightingale I cannot do better than repeat “_c’est un bijou_.”
Ornithologists assure us that there are three species of nightingale. There is the Western nightingale (_Daulias luscinia_), which visits England in the summer and fills the woods with its glorious melody. Then there is the Eastern species or variety which is also known as the sprosser (_D. philomela_), and, lastly, the Persian nightingale, the _hazar-dastan_ or _bulbul_ of the Persian poets. This last variety is known to men of science as _Daulias golzii_.
It would puzzle the ordinary man to distinguish between these various races. The length of the tail is one test. If the nightingale have a tail well over three inches in length it is the Persian form, if well under three inches it is a Western nightingale, and if about three inches a sprosser. The nightingale, as every one knows, is a small bird varying from 6½ to 7½ inches in length. Both sexes dress alike and in the plainest manner possible, the upper plumage being russet brown and the lower pale buff.
As we have seen, one of the Persian names of the nightingale is “bulbul.” This has given rise to considerable misunderstanding regarding the existence of nightingales in India. Every one knows that India teems with bulbuls, and as “bulbul” is the Persian for nightingale, the average Englishman labours under the delusion that Hindustan abounds with nightingales which fill the soft Indian night with melody, at the time
“When mangoes redden and the asoka buds Sweeten the breeze and Rama’s birthday comes.”
Now, as a matter of fact, the Indian bulbul has nothing whatever to do with the nightingale. There can, I think, be but little doubt that the Persian poets have misapplied the word “bulbul” in using it to denote the nightingale. The term “bulbul” is familiar to every native of India as meaning one of the Brachypodous birds belonging to the genera _Molpastes_, _Otocompsa_, etc., and as there are true bulbuls in Persia, one of which, _Molpastes leucotis_, is a good singer, it is probable that the poets, who are notoriously bad naturalists, have misapplied the name of this songster to an even better singer, namely, the nightingale. And this name, having been immortalised by Hafiz and others, will always remain. We must, therefore, be careful to distinguish between the true bulbuls, which are not very brilliant singers, and the nightingale, which in India is known as the _bulbul bostha_, or _bulbul basta_. Numbers of Persian nightingales are captured and sent in cages to India, where they are highly prized on account of their vocal powers. A good singing cock will fetch as much as Rs. 400 in Calcutta. The cock nightingale alone sings, and as he is indistinguishable in appearance from the hen, a would-be purchaser, before paying a long price for one of these birds, should insist on hearing it sing. Nightingales thrive in captivity if provided with a plentiful supply of insect food. The Western and Eastern forms have both bred in captivity, and the Persian variety will doubtless do likewise if given proper accommodation.
Indian bulbuls, then, are not nightingales. Nor are nightingales common in that country. Oates, it is true, includes _Daulias golzii_ among the birds of India, but, in my opinion, on insufficient evidence. He admits that it is of extreme rarity in the country, “only two instances of its occurrence being known.” Hume, in October, 1865, had a Persian nightingale sent to him, which was said to have been procured in the Oudh terai. It is probable that neither this specimen nor the other whose presence is recorded in India was a wild bird at all; as likely as not they were caged birds that had escaped from captivity! The nightingale is certainly a very retiring bird, and since, if it occurs in India, it can be only as a winter visitor when it is not in song, it is possible that it might be overlooked. But in face of the fact that many good ornithologists have spent long periods in Oudh without ever having seen a nightingale, and the bird has never been observed anywhere else in India, it seems most improbable that nightingales ever stray into India. What, then, are we to think of the statement of Dr. Hartert, a German ornithologist, who says of the Eastern nightingale that “it winters in Southern Arabia, parts of India (e.g. Oudh) and East Africa”?
Here we have an excellent illustration of the adage “A little learning is a dangerous thing,” a good example of how erroneous statements creep into scientific books. Dr. Hartert has heard that nightingales have been recorded in Oudh, so jumps to the conclusion that the species winters there, even as it does in Egypt. This statement will doubtless be copied, without acknowledgment, into many future text-books, for plagiarism is very rife among men of science; and thus the popular notion that nightingales are common in India will be fortified by scientific support! Nightingales undoubtedly do winter in India—but only in cages. We have many fine songsters in Hindustan, but the nightingale is not one of them.
XXV THE WIRE-TAILED SWALLOW
Were each species of bird to record in writing its opinion of men, the resulting document would certainly not be flattering to the human race. The inhumanity of man would figure largely in it. The majority of the feathered folk have but little cause to love their human neighbours. Men steal their eggs, destroy their nests, kill them in order to eat them or to decorate women with their plumage, and capture them in order to keep them in cages. A few species, however, ought to regard man with friendly eyes, for they owe much to him. The swallow tribe, for example, must acknowledge man as its greatest benefactor. Take the case of the common swallow (_Hirundo rustica_), the joyful herald of the English summer, the bird to which Gilbert White devotes a particularly charming letter. All the places in which this species builds owe their origin to human beings. The myriads of swallows that visit Great Britain in the spring find in the chimneys of houses ideal nesting places—hence the birds are known as house or chimney swallows.
“The swallow,” writes White, “though called the chimney swallow, by no means builds altogether in chimneys, but often within barns and outhouses against the rafters, and so she did in Virgil’s time:
‘Ante Garrula quam tignis nidos suspendat hirundo.’
“In Sweden she builds in barns, and is called _ladu swala_, the barn swallow. Besides, in the warmer parts of Europe there are no chimneys to houses, except they are English-built. In those countries she constructs her nest in porches and gateways and galleries and open halls. Here and there a bird may affect some odd, peculiar place, as we have known a swallow build down the shaft of an old well through which chalk had been formerly drawn up for the purpose of manure; but in general with us this _Hirundo_ breeds in chimneys, and loves to haunt those stacks where there is a constant fire, no doubt for the sake of warmth. Not that it can subsist in the immediate shaft where there is a fire, but prefers one adjoining to that of the kitchen, and disregards the perpetual smoke of that funnel, as I have often observed with some degree of wonder.”
In the days before man began to build substantial houses for his habitation, the swallows can have nested only in caverns and under natural ledges in cliffs, so cannot have existed in anything like their present numbers. _Hirundo rustica_ is a common bird in India. During the winter it spreads itself over the plains, and may be seen, as in England, dashing through the air after tiny insects. In the East the gentle twittering of the birds as they propel themselves through the air sounds doubly sweet, since it recalls scenes in our distant island. The swallows which winter in India migrate to the Himalayas or Kashmir or Afghanistan, where they rear up their families.
But to-day I write of a more beautiful bird even than _Hirundo rustica_, of the most beautiful of the swallow kind, of a species on which Gilbert White could not have set eyes. Like the common species, the wire-tailed swallow (_Hirundo smithii_) is a glossy, steel-blue bird. The forehead, crown, and nape are chestnut, and all the lower plumage, including the chin, is white. In this last respect it differs considerably from the common swallow, which has the chin and throat chestnut, a black pectoral band, and the rest of the under parts pale reddish brown. In both species there is a white spot on each of the tail feathers, except the median pair. These white spots are very conspicuous when the bird sits with tail expanded.
The chief characteristic of _Hirundo smithii_ is the great development of the shafts of the outer tail feathers. In most swallows the shaft is elongated. In _H. rustica_ it extends 2½ inches beyond the other tail feathers. In the wire-tailed swallow the shaft of each of the outer tail feathers attains a length of seven inches, and is thus more than twice as long as the body of the bird. This swallow, indeed, looks as though two pieces of wire had been inserted into its tail; hence the popular name, which is far more appropriate than the scientific one. Jerdon called this species _H. filifera_, an excellent name, but among cabinet ornithologists the excellence or appropriateness of a bird’s name counts for nothing. Many years ago a member of the Smith family made the acquaintance of the bird, and it was named after him. This name being the oldest is the one by which we must call the bird until some bibliophile manages to unearth some yet earlier name.
The elongated shafts of the outer tail feathers are brittle and easily broken, so that it is the exception rather than the rule to see a bird with both the delicate filiferous appendages complete.
The habits of this swallow are similar to those of other species, except that it is probably not migratory. It is found all the year round in the plains of North-West India. It is rare in Lower Bengal, Assam, Upper Burma, and in South India. Although it occurs in the Madras Presidency, it is not often seen as far south as the city of Madras. Since water is always conducive to the presence of the small insects on which swallows feed, these birds usually seek their quarry in the vicinity of the liquid element, and naturally roost near their feeding grounds. This fondness for the neighbourhood of water doubtless gave origin to the once prevalent belief that some swallows did not leave England in the autumn, but remained behind and hibernated underwater. This idea is, of course, erroneous.
Wire-tailed swallows like to roost in considerable companies in the minarets of mosques or in other lofty towers. Unlike swifts, swallows frequently perch. Telegraph wires are a very favourite resting place. When these are not available the birds will settle on stones or tufts of grass.
As chimneys are scarce in the plains of India, the wire-tailed swallow has to look elsewhere for nesting sites. True to the traditions of its family, it almost invariably elects to build on some structure erected by man. Nine out of ten nests are built under the arches of low bridges or culverts, preferably those under which there is a little water lying. The nest projects from the arch like a little shelf. It resembles a deep saucer in shape, and is composed of a shell of mud, lined with feathers.
Wire-tailed swallows obtain the mud they use from the edge of water, and carry it in the bill in precisely the same way as the house martin does in England. One of the prettiest sights of a London suburb is to watch the house martins taking the materials for their nests from a muddy road, which they always contrive to do without soiling their white-feathered legs. Muddy roads are not common in India, hence wire-tailed swallows are not able to resort to them for nest-building materials.
The cup of the nest is usually fairly thick, especially at the place where the nest is attached to its foundation. The outside of the cup has a rugged appearance, and each of the projections which it displays corresponds to a mouthful of mud added to it by the bird. According to Mr. James Aitken, the birds occupy about four weeks in building the nest, “a narrow layer of mud being added each day and left to dry.”
When once a pair of wire-tailed swallows have made up their minds to nest in a certain spot they are not easily deterred from carrying out their intention. Mr. Aitken admits having on one occasion removed two eggs, out of a clutch of three, but the little mother sat on and hatched out the one egg that remained. A man of my acquaintance, who, although an egg collector, is not altogether devoid of the milk of kindness, always carries about with him one or two sparrow’s eggs which he exchanges for the birds’ eggs he wishes to add to his collection. One May day at Lahore this person came upon a wire-tailed swallow’s nest which contained one egg. This he removed, and substituted for it a sparrow’s egg. The owners of the nest either did not, or pretended not to, notice the exchange, and the hen laid two more eggs, so that when I visited the nest three days later I found that two legitimate eggs had been placed beside the spurious one. The incubating bird sat very tight, and allowed me to touch her, and had I wished to do so I could easily have caught her; such is the strength of the incubating instinct in some birds. The nest in question was built under a low arch, one end of which was blocked up. The only other occupants of the arch were a number of wasps. Birds seem to have little or no fear of wasps. Indeed, it is rather the wasps that fear the birds, which have a disagreeable habit of swallowing them, notwithstanding their sting and warning colouration! Three weeks later I paid another visit to the arch in question, and found that the swallow’s nest had been removed by some person or persons unknown, but under the same arch was another nest containing two eggs. It would seem that the plucky little birds, undaunted by the fate of their first nest and eggs, had quickly set to work to make good the loss.
XXVI WINTER VISITORS TO THE PUNJAB PLAINS
Six months ago we welcomed the birds that came to spend the summer with us—the tiny iridescent purple sunbird, the emerald bee-eater, its larger blue-tailed cousin, the golden oriole, the superb paradise flycatcher, the yellow-throated sparrow, the solemn night heron, and the noisy koel.
These have all built their nests, reared up their families (except, of course, the koels who made the crows do their nursemaids’ work) and departed. The sunbirds were the first, and the koels the last, to go. By August the former had all disappeared, but throughout the first half of October young koels were to be seen, perched in trees, flapping their wings, opening a great red mouth, and making creditable but ludicrous attempts at cawing.
Even the koels have now gone and will not reappear until the sun once again causes us human beings to wonder why we have come to this “Land of Regrets.”
The places left vacant by the summer visitors are being rapidly filled up. Lahore has for birds a winter as well as a summer season. The former is the more important of the two. So numerous are our winter bird visitors that it is not feasible to enumerate them in this place; we must be content with a glimpse at those which come in the greatest numbers and are, therefore, most likely to attract attention.
The earliest to arrive are the rosy starlings (_Pastor roseus_) or _Gulabi Mainas_, or _Tilyers_ as the natives call them. They are easy to recognise. They go about in great flocks. When a flock settles on a tree it is a point of etiquette for all the individuals that compose it to talk simultaneously. The head, crest, neck, throat, upper breast, wings, and tail are glossy black. The rest of the plumage is a beautiful rose colour in the adult cock and pale coffee colour in the hens and young cocks.
Rosy starlings arrive in Lahore as early as July. As they do not leave us until the end of April, and are supposed to nest in Asia Minor, it might be thought that they are the discoverers of some specially rapid method of nest-construction, egg-incubation, and bird-rearing. This is not so. The fact is they do not migrate simultaneously. The birds that were in Lahore in such numbers last April are not those which appeared in July. These latter probably migrated to Asia Minor in February.
It is only in the spring that the rosy starlings go about in very large flocks; these are the result of “packing” prior to migration. At other times the birds occur in nines and tens and associate with the ordinary mynas, feeding either on fruit or grain.
