Part 14
Terns are so beautiful that, where they occur, they are apt to attract unto themselves all attention. This is, I think, the reason why so little is on record regarding the swallow-plovers, which haunt all the larger rivers of India to such an extent that it is scarcely possible to spend an hour on the Ganges, the Jumna, the Gogra, the Indus, the Brahmaputra, the Nerbudda, the Mahanuddy, or even the distant Irawaddy without meeting with a flock of those curious little birds.
Swallow-plovers, or pratincoles, as they are often called, are easily described. They are plovers that subsist largely upon flying insects which they catch when on the wing. As a result of this habit swallow-plovers (_Glareola lactea_) have taken on some of the attributes of the swallow, notably the long wings and the broad gape.
The total length of a swallow-plover, including the tail, is 6½ inches, while the wing alone is nearly six inches long. It is these long wings that give the bird a swallow-like appearance.
The general hue of _Glareola lactea_ is that curious sandy-grey shade of brown which, for some occult reason, is known as isabelline. The short tail is white with a black tip. There is a black streak through the eye and a white one near the margin of the wing. The abdomen is white. The legs are short for those of a plover; nevertheless, the species is very nimble on its feet, and runs in the manner peculiar to the peewit family.
Swallow-plovers are to be found at a distance from water, but they are essentially river birds.
At sunset, when insects in their myriads disport themselves over the surface of rivers, the swallow-plovers issue forth and hawk these flying hexapods just as swallows do, and, as they fly low over the face of the waters, they are doubtless often mistaken for swallows.
Jerdon states that swallow-plovers live exclusively on insects which they catch on the wing. I doubt whether this assertion is correct. These birds certainly feed largely on flying insects, but as they spend the major part of their time on the sand, over which they run swiftly, I think that creeping things constitute a not inconsiderable portion of their diet.
Their nesting habits are similar to those of terns and plovers; that is to say, the eggs are placed on the sand or bare ground without any semblance of a nest.
I make a point every year, if possible, of spending a morning on a river at the beginning of the hot weather looking for the nests of terns and other birds which lay on _churs_ and sandbanks. Almost every Indian river is plentifully studded with islets which render its navigation difficult, but afford most convenient nesting sites for many species of birds. The sandy islets whereon eggs are laid are nearly always those of which some portion is sufficiently high to escape being flooded when the river rises in consequence of the melting of the snow on the higher peaks of the Himalayas. The selected islands are almost invariably sufficiently far from the river bank to prevent jackals and other predaceous creatures wading across to them. If terns or plovers fail to take such precautions, the chances are that their eggs will come to grief.
This year (1912), on the 15th April, I went out on the Gogra at Fyzabad, and found over thirty nests of swallow-plovers on one islet, on which I also saw two eggs of the black-bellied tern (_Sterna melanogaster_).
Immediately I set foot on the island the terns and small pratincoles commenced making an uproar, which, of course, amounted to an assurance that they had eggs on the island. One portion of it was well sprinkled with stunted vegetation, and thither I at once repaired, to the great disgust of the swallow-plovers, who flew about excitedly, uttering their lapwing-like cry—_titeri, titeri_. A search of less than a minute served to reveal a couple of eggs placed on the bare ground between two small plants that were growing out of the sand. As I stooped down to examine these eggs I looked round and saw a very curious and pretty sight. Swallow-plovers were surrounding me. They were nearly all on the ground and striking strange attitudes. Some were lying on the sand as though they had been wounded and fallen to the ground; others were floundering on the ground as if in pain; some were fluttering along with one wing stretched out limply, looking as though it were broken; while others appeared to have both wings injured. I did not count the birds, but at least twenty of them were seemingly injured. I had often seen one bird or a pair behave thus, but never a whole flock.
All the plover family have this injury-feigning instinct, but in none is it so well developed as in the pratincoles.
“The strange antics,” writes Hume, “played by these little birds, at least those of them that had young or hard-set eggs, whenever we approached their treasures were very remarkable; flying past one, they would come fluttering down on to the sand a few paces in front of one, and there gasp and flutter as if mortally wounded, hobbling on with draggled wings and limping legs as one approached them, and altogether simulating entirely helpless and completely crippled birds. No one unacquainted with the habits of this class of birds could have believed, to see them flapping along on the sands on their stomachs, every now and then falling head over heels and lying quite still for an instant, as if altogether exhausted, that this was all a piece of consummate acting intended to divert our attention from their nests.”
Hume here voices the popular opinion that birds, when they behave as though they are injured, are deliberately pretending to be wounded with the object of diverting the attention of an intruder from their eggs or young. I hold this view to be utterly and entirely wrong. Consider the long chain of reasoning that a bird has to make before behaving as swallow-plovers are supposed to do. In the first place the birds must know or believe that the intruder has come with the object of taking their eggs or young ones. They must know or believe that the said intruder would like to capture them in preference to their eggs or young. They must further have discovered that a bird with a leg or a wing broken is easier to capture than one that is sound in limb. They must also know how a bird with a broken wing or leg behaves when endeavouring to escape from a foe. Knowing and believing all these things, the swallow-plover must reason thus within itself: “If I pretend that I am injured the intruder will try to catch me and thus be drawn away from my eggs or young. I will, therefore, proceed to act the wounded bird to the best of my ability.”
I do not for a moment believe that the average swallow-plover has half this knowledge and power of reasoning. Its behaviour can be accounted for in a far more probable manner. We all know that instinct teaches birds to fly away from all birds or beasts of prey or large strange moving objects; but instinct teaches them to guard their eggs. Now, when a human being approaches the eggs of a pratincole, these two instincts come into violent opposition, and the bird’s mental equilibrium is much disturbed; the result is that the bird undergoes all manner of strange contortions. We look at these and say, “What a clever little bird! How well it is acting!” The contortions of the swallow-plover undoubtedly do tend to attract the attention of predaceous creatures, and are probably useful to the species when there are young, for these are able to slip away while the attention of the attacker is momentarily diverted by the parent birds. Hence such behaviour must tend to be perpetuated by natural selection. That it is in no sense an intelligent act is obvious from the fact that such behaviour occurs when there are eggs, and so can do no good; moreover, the parents will go on behaving in this manner even after the intruder has taken the eggs and put them in his pocket!
Textbooks tell us that _Glareola lactea_ lays from two to four eggs. I have never found more than two in a clutch, and think that Hume made a mistake when he said “from two to four,” and as plagiarism is very rife among writers on ornithology, other ornithologists have copied his statements without acknowledgment, and, of course, reproduced his mistake!
The eggs of this species are interesting on account of the extraordinary variations they exhibit. As Hume well says, it is scarcely possible to find two eggs (outside the same clutch) that closely resemble each other. It not infrequently happens that the two eggs in the same clutch differ so greatly that it is difficult to believe that they are the produce of one hen. The ground colour may vary from pale green, almost white, to fawn colour. The markings sometimes take the form of blotches, so that the eggs look like those of a small tern. More usually the markings appear as tiny spots, freckles, pencillings, or cloudy smudges. On a sandbank containing twenty nests it is possible to pick out ten eggs, each of which differs so greatly from the others that the casual observer would certainly say they all belonged to different species. The size is, of course, fairly uniform, but the shape varies greatly; some are elongated, while others are nearly as broad as they are long. Occasionally a pear-shaped egg is found, but as a rule the narrow end of the egg is comparatively blunt. That eggs which are laid on the sand in the open should display these extraordinary variations is an awkward fact for those who consider that the colouring of birds’ eggs is the direct result of natural selection. If this were so we should expect to find a wonderful sameness about the eggs of this species, which are laid in such exposed situations. The fact is, of course, that on a sandbank eggs of any colour that is not too pronounced are difficult to see; hence, for purposes of protection, the actual colours of the background and the markings of the egg are matters of little importance.
XXXIII THE BIRDS OF A MADRAS GARDEN
Richard Jefferies devotes several chapters of one of the most delightful of his books—_Wild Life in a Southern County_—to the birds that frequent a farm on the Downs. “On looking back,” he writes, “it appears that the farm-house, garden, orchard, and rickyard at Wick are constantly visited by about thirty-five wild creatures, and, in addition, five others come now and then, making a total of forty. Of these forty, twenty-six are birds, two bats, eight quadrupeds, and four reptiles. This does not include some few additional birds that only come at long intervals, nor those that simply fly overhead or are heard singing at a distance.
“Around the farm-house itself come the starlings, sparrows, swallows, water wagtails, hedge-sparrows, robins, wrens, tomtits, thrushes, and blackbirds. The orchard is frequented by sand martins, cuckoos, missel thrushes, goldfinches, greenfinches, flycatchers, linnets, blackcaps, and titmice.
“In the rickyard are seen redstarts, stone-chats, rooks, chaffinches, wood-pigeons, doves, and larks.”
Now a closer observer of nature than Richard Jefferies never existed, and he knew every square yard of the Wick Farm, so that we may be sure that the list he gives is exhaustive.
This list seems very meagre to one who is accustomed to bird life in India. If the Wick Farm were transported bodily and set down in the middle of India it would be visited by seventy or eighty species of birds instead of twenty-six.
Every garden of tolerable size in Madras is the abode of quite twice as many birds as those which visit a downland farm in England, so superior is India to England as a field for the ornithologist.
Every Madrassi whose bungalow is placed in a garden worthy of the name may, without leaving the same, count upon seeing fifty species of birds before he has been many months in the country.
First there are the perennials—the birds which, like the poor, are always with us—the jungle and the house crows, the white-headed babbler, the iora, the red-vented and the white-browed bulbuls, the king-crow, the tailor bird, the common and the brahmany mynas, the common sparrow, the golden-backed woodpecker, the bush lark, Loten’s and the purple-rumped sunbirds, the coppersmith, the white-breasted kingfisher, the hoopoe, the koel, the crow-pheasant, the spotted owlet, the common and the brahmany kites, the spotted and the little brown doves, and the cattle egret; while if the garden boast of anything in the shape of a pond there will be found the common kingfisher and the paddy bird.
Nearly all these birds nest in the compound, and all are so familiar to every Anglo-Indian that no description is needed. Moreover, I have, I think, previously treated of all of them with the exception of the iora (_Aegithina tiphia_). In case there be any who are unable to give this beautiful little species a name when they see or hear it, let me briefly describe it. It is considerably smaller than a sparrow, and lives amid the foliage, from which it picks the tiny insects that constitute its food. In summer the upper parts of the cock are black, and the lower parts bright yellow. There are two narrow white bars in the wing. In winter the black on the head and back is replaced by yellowish green. The hen has the upper plumage and tail green, and the lower parts yellow. She also has the two white wing bars. To my mind the iora is a good songster. Nevertheless, “Eha” states that it “has no song, but scarcely any other bird has such a variety of sweet notes.” I will not quarrel over the meaning of the word song; every one who knows the iora must agree that it continually makes a joyful noise.
Less common than the birds named above, but occupants of almost every garden, are the butcher birds and their cousins the wood-shrikes, the fantail flycatchers, and the pied wagtails, the emerald bee-eaters, and parakeets, the robin and the palm swift.
The commonest species of butcher bird in Madras is the bay-backed shrike (_Lanius vittatus_), a small bird with a grey head and a maroon back, and a broad black streak through the eye. This tyrant of the garden takes up a perch on a bare branch, and there remains like a sentinel on a watch-tower, until it espies an insect on the ground. On to this it swoops, displaying, as it descends, much white in the wings and the tail.
The wood-shrike (_Tephrodornis pondiceranus_) frequents trees and hedgerows. But for its broad white eyebrow and the white in its tail, it might pass for a sparrow. It is most easily recognised by its melodious and cheerful call—_tanti tuia, tanti tuia_.
The pied wagtail (_Motacilla maderaspatensis_)—elegance personified—loves to sit on the housetop and pour forth a lay which vies with that of the canary. Suddenly away it flies, speeding through the air in undulating flight, until it reaches the ground, where, nimble-footed as Camilla, it chases its insect quarry.
The fantail flycatcher (_Rhipidura albifrontata_) is another study in black and white. This most charming of birds frequents leafy trees, whence it pours forth its sweet song of six or seven notes. Every now and again it, after the manner of all flycatchers, sallies into the air after insects. Having secured its victim, it alights on a branch or on the ground, and there spreads out its tail and turns as if on a pivot, now to one side, now to the other.
We must seek the robin (_Thamnobia fulicata_) among the tangled undergrowth in some corner of the compound neglected by the gardener. There shall we find the pair of them—the cock a glossy black bird with a narrow white bar in the wing, the hen arrayed in a gown of reddish brown. In each sex there is a patch of brick-red feathers under the tail, and, as if for the purpose of displaying this, the tail is carried almost erect.
If there be any fruit ripening, even if it be that of the cypress, green parrots (_Palaeornis torquatus_) are certain to visit the garden. On the approach of a human being these feathered marauders will fling themselves into the air with wild screams, and dash off, looking, as Lockwood Kipling says, like “live emeralds in the sun.”
Even more like living emeralds are the little green bee-eaters (_Merops viridis_), whose feeble twitter may emanate from any tree. Take a huge emerald and cut it into the shape of a bird. Insert a pale blue turquoise at the throat, rubies for the eyes, and set these off with strips of darkest emery, let into the head a golden topaz, then breathe into this collection of gems the breath of life, and you will have produced a poor imitation of that gem of the feathered world—the little emerald merops.
If there be palm trees in the garden the presence of the little palm swift (_Tachornis batassiensis_) is assured. Palm swifts are tiny smoky-brown birds which travel unceasingly through the air in pursuit of the insects on which they feed. During flight the wings remain expanded, looking like a bow into the middle of which the slender body is inserted.
I had almost forgotten one of the most striking birds in the world—the Indian paradise flycatcher (_Terpsiphone paradisi_), which certainly is entitled to a place among the common birds of a Madras garden. The cocks are white or chestnut, according to age. The crested head is shining black, and the two median tail feathers are greatly elongated, so that they flutter in the air like satin streamers as the bird flits about among the trees. The hen lacks the lengthened tail feathers, and, as “Eha” says, looks like a chestnut-coloured bulbul. Indeed, Anglo-Indian boys call this species the _Shah Bulbul_.
There are a number of occasional bird visitors to our Madras gardens.
## Parties of minivets and cuckoo shrikes come and seek for insects among
the leaves of trees. The unobtrusive yellow-throated sparrow (_Gymnorhis flavicollis_) is another tree-haunting species to be looked for in the garden. Conspicuous among the less common birds which feed on the ground are the gorgeous roller or “blue jay,” the sprightly magpie robin, the white-throated munia, attired like a quaker, and that bird of many colours the Indian pitta, which keeps always near thick underwood, sometimes issuing from thence into the open to give forth a cheery whistle.
In conclusion, mention must be made of the migrant species. Many of the birds that come to the farm on the downs of which Jefferies wrote—the swallows, the cuckoos, and the wagtails—are but summer visitors to England. So do a number of migrating species visit our Madras gardens. There is, however, this difference in the two cases. The migrating species visit England in summer for nesting purposes, whereas they spend the winter in warm Madras, and leave it in summer before the nesting time begins.
Among the winter visitors which come into the garden must be mentioned the beautiful Indian oriole, a study in yellow and black, the Indian redstart, or, to give it its older name, the fire-tail, the grey-headed wagtail, whose under parts are bright yellow, the dull earthy-hued little Sykes’s warbler, which hides itself in a bush and keeps on calling out _chick_, and the grey-headed myna, which, but for the fact that the head and recumbent crest are grey, might easily pass for a brahmany myna.
The birds above enumerated do not form by any means an exhaustive list. Were birds that sometimes come into the garden included, the list would extend to three times its present length.
XXXIV SUNBIRDS
Sunbirds, or honey-suckers as they are sometimes called, are to the tropics of the Old World what humming birds are to the warmer portions of the New World.
Sunbirds are tiny feathered exquisites which vary in length from 3½ to 5 inches, including a bill of considerable length for the size of the bird.
They are numbered among the most familiar birds of India, owing to their abundance and their partiality to gardens. They occur all the year round in the warmer parts of the peninsula, but leave the coldest regions for a short time during the winter.
Twenty-nine species of sunbirds are described as belonging to the Indian Empire, but most of them are only local in their distribution. Three species, however, have a considerable range. These are _Arachnechthra asiatica_, the purple sunbird, which occurs throughout India and Burma, ascending the hills to 5000 feet; _A. zeylonica_—the purple-rumped sunbird—which is the commonest sunbird in all parts of Southern India except Madras, where the third species, _A. lotenia_—Loten’s sunbird—is perhaps more abundant.
The genus _Arachnechthra_ is characterised by a great difference in appearance between the sexes. The hens of all the species are very like one another; all are homely-looking birds, dull greenish brown above and pale yellow below. The cocks of the various species are arrayed in metallic colours as resplendent as those that decorate humming birds.
Seen from a little distance, the cock of the purple-rumped species is a bird with dark head, neck, wings, back, and tail, and bright yellow under parts, while the female is brown above and yellowish beneath. Thus at a distance the male does not look much more beautiful than the female, but if one is able to creep up sufficiently near him his plumage is seen to be unsurpassable; it glistens with a splendid metallic sheen, which is purple or green according to the direction from which the sun’s rays fall upon it. On the top of the head is a patch of brilliant shining metallic green, which exceeds in beauty any crown devised by man.
The cocks of the purple and Loten’s species are very much alike, but may be readily distinguished by the fact that the slender curved bill of Loten’s is considerably longer than that of its cousin. How shall I describe these beautiful birds? In my volume _Indian Birds_ I classed them among black birds, because they look black when seen at a distance, but I stated that they are in reality dark purple, and have been taken to task for not classing them among the blue birds. The fact of the matter is that these birds cannot be said to be of any colour; like shot silk, their hue depends upon the angle at which the sun’s rays fall upon them. In the sunlight their plumage glistens like a new silk hat, and sometimes the sheen looks lilac and at others green.
The habits of all three species appear to be exactly alike.
The cocks of all have fine voices. At his best the purple sunbird sings as sweetly as a canary. Indeed, on one occasion when I was staying at Bangalore I heard a bird singing in the verandah which I thought was a caged canary; it was only when I went to look at the canary that I discovered it to be a wild sunbird pouring forth its music from some trellis-work!
Sunbirds are always literally bubbling over with energy. They are bundles of vivacity—ever on the move. Although they eat tiny insects, they subsist chiefly on the nectar of flowers, which appears to be a most stimulating diet.
