THE BLACK-AND-YELLOW GROSBEAK_
The Indian grosbeaks are birds of limited distribution; they appear to be confined to the forests on the higher ranges of the Himalayas. Their most striking feature is the stout conical bill, which is an exaggeration of that of the typical finch, and is responsible for the bird's name. In one genus of grosbeak--_Mycerobas_--the bill is as deep as it is long, while in the other genus--_Pycnorhamphus_--it is nearly as massive. Three species belonging to this latter genus occur in India, namely, _P. icteroides_, the black-and-yellow grosbeak, found in the Western Himalayas; _P. affinis_, the allied grosbeak, found in Nepal, Sikkim, Tibet, and Western China; and _P. carneipes_, the white-winged grosbeak, which occurs all along the higher Himalayas.
There is only one Indian species of the other genus; this is known as the spotted-winged grosbeak (_Mycerobas melanoxanthus_), the localities in which this occurs are said to be "the Himalayas from the Hazara country to Sikkim at considerable elevations and Manipur."
The only Indian grosbeak which I have met in the flesh is the yellow-and-black species. This bird is common in the hills round about Murree, so that, when on ten days' leave there, I had some opportunity of studying its habits. It is a bird of the same size as the Indian oriole (_Oriolus kundoo_). The cock grosbeak, indeed, bears a striking resemblance to the black-headed oriole (_Oriolus melanocephalus_). His whole head, chin, throat, wings, shoulders, upper-tail-coverts, and thighs are black, the remainder of the plumage is a rich yellow, tinged with orange at the hind neck. Thus the colour and markings are almost identical with those of the black-headed oriole, the chief difference being that the latter has a little yellow in the wing. So great is the resemblance that the casual observer will, in nine cases out of ten, mistake the grosbeak for an oriole. The resemblance extends to size and shape, as the following table shows:
Length Length Length Length Length of Bird. of Tail. of Wing. of Tarsus. of Beak. Grosbeak . . 9.0 in. 3.7 in. 5.2 in. 1.0 in. 1.0 in. Oriole . . . 9.5 " 3.4 " 5.4 " 1.0 " 1.3 "
The hen grosbeak differs considerably in colour and marking both from the cock of her species and from the hen black-headed oriole. She is a dull ashy-grey bird, tinged faintly with yellowish red on the back and abdomen. Her wings and tail are black. The only young grosbeak that I have seen resembled the female in appearance, except that it had a yellow rump. It was being fed by a cock bird.
Grosbeaks live in forests, and go about either in couples or in small companies. They seem to feed largely on the ground, picking up insects. The beak of the finch tribe is adapted to a diet of seeds; nevertheless, many finches vary this food with insects. I saw a grosbeak seize, shake, and devour a caterpillar about two inches in length. Grosbeaks also eat berries and stone fruit. When disturbed they at once betake themselves to a tree, among the branches of which they are able to make their way with great agility. Grosbeaks are restless birds, always on the move, here to-day and gone to-morrow. The cock emits a call at frequent intervals. This is not easy to describe. It sounds something like _kiu kree_.
The nest is a cup-shaped structure, composed exteriorly of twigs, grass, and moss, and lined with stalks of maiden-hair fern and fine roots. It is usually placed high up in a fir tree. Colonel Rattray believes that the birds bring up two broods in the year. They lay first in May, and, as soon as the young are able to shift for themselves, a second nest is made. Thus in July both young birds at large and nests with eggs are likely to be seen. The eggs are not unlike those of the English hawfinch; the ground colour is pale greenish grey, blotched and spotted with blackish brown. Sometimes the markings occur chiefly at the broad end of the eggs.
The most striking feature of the black-and-yellow grosbeak, and that on which I wish particularly to dwell, is the extraordinary resemblance that the cock bird bears to the cock black-headed oriole. If this extended to the hen, and if the grosbeak were parasitic on the oriole, it would be held up as an example of mimicry. We should be told that owing to its resemblance to its dupe it was able to approach the nest without raising any suspicion and deposit its egg. But the grosbeak is not parasitic on the oriole, and it is the cock and not the hen that bears the resemblance; moreover, the black-headed oriole does not occur in the Himalayas, so that neither the grosbeak nor the oriole can possibly derive any benefit from this resemblance.
Now, cabinet zoologists are never tired of writing about mimicry. They assert that when organisms belonging to different families bear a close external resemblance, this resemblance has been brought about by natural selection. Having made this assertion, they expend reams of paper in demonstrating how one or both of the species benefits by the resemblance.
However, scientific books make no mention of the resemblance between the oriole and the grosbeak. The reason for this is, of course, that the resemblance in this instance cannot be a case of mimicry. Now, I regret to have to say that men of science take up the same attitude towards their theories as lawyers do regarding the cases they argue in Courts of Justice. There would be no harm in taking up this attitude if men of science were to explain that they are acting the part of advocates, that they are fighting for a theory, and trying to persuade the world to accept this theory. It is because they masquerade as judges, and put forward a one-sided case as a matured judicial finding, that I take exception to their methods.
The trouble is that scientific men to-day form a brotherhood, a hierarchy, which lays claim to infallibility, or rather tacitly assumes infallibility.
They form a league into which none are admitted except those who take the oath of allegiance; and, of course, to expose the weakness of the scientific doctrines of the time is equivalent to violating the oath of allegiance. Now, the man of science who has to earn his living by his science, has either to join the league or run the risk of starving. This explains how a small coterie of men has things very much its own way; how it can lay down the law without fear of contradiction. If a man does arise and declines to accept the fiats of this league, it is not difficult for the members to combine and tell the general public that that man is a foolish crank, who does not know what he is talking about; and the public naturally accepts this dictum.
The only scientific men who, as a class, are characterised by humility are the meteorologists. I always feel sorry for the meteorologist. He has to predict the weather, and every man is able to test the value of these predictions. The zoologist, on the other hand, does not predict anything. He merely lays down the law to people who know nothing of law. He assures the world that he can explain all organic phenomena, and the world believes him.
As a matter of fact, zoology is quite as backward as meteorology. Those who do not wish to be deceived will do well to receive with caution all the zoological theories which at present hold the field. Before many years have passed all of them will have been modified beyond recognition. Most of them are already out of date.
There are doubtless good reasons for the colouring of both the grosbeak and the oriole; what these reasons are we know not. But as neither derives any benefit from the resemblance to the other, this _resemblance_ cannot have been effected by natural selection. Now, if the unknown forces, which cause the various organisms to take their varied colours and forms, sometimes produce two organisms of different families which closely resemble one another, and the organisms in question are so distributed that neither can derive the slightest advantage in the struggle for existence from the resemblance, there is no reason why similar resemblances should not be produced in the case of organisms which occupy the same areas of the earth. Thus it is quite possible that many so-called cases of mimicry are nothing of the kind.
The mere fact that one of the organisms in question may profit by the likeness is not sufficient to demonstrate that natural selection is responsible for the resemblance.
In this connection we must bear in mind that, according to the orthodox Darwinian theory, the resemblance must have come about gradually, and in its beginnings it cannot have profited the mimic _as a resemblance_.
So plastic are organisms, and so great is the number of living things in the earth, that it is not surprising that very similar forms should sometimes arise independently and in different parts of the globe. Several instances of this fortuitous resemblance are cited in Beddard's _Animal Colouration_; others are cited in _The Making of Species_ by Finn, and myself.
Perhaps the most striking case is that of a cuckoo found in New Zealand, known as _Eudynamis taitensis_. This is a near relative of the Indian koel, which bears remarkable resemblance to an American hawk (_Accipiter cooperi_). Writing of this cuckoo, Sir Walter Buller says: "Not only has our cuckoo the general contour of Cooper's sparrow-hawk, but the tear-shaped markings on the underparts, and the arrow-head bars on the femoral plumes are exactly similar in both. The resemblance is carried still further, in the beautifully-banded tail and marginal wing coverts, and likewise in the distribution of colours and markings on the sides of the neck. On turning to Mr. Sharpe's description of the young male of this species in his catalogue of the Accipitres in the British Museum, it will be seen how many of the terms employed apply equally to our Eudynamis, even to the general words, 'deep brown above with a chocolate gloss, all the feathers of the upper surface broadly edged with rufous.' ... Beyond the general grouping of the colours there is nothing to remind us of our own Bush-hawk; and that there is no great protective resemblance is sufficiently manifested, from the fact that our cuckoo is persecuted on every possible occasion by the tits, which are timorous enough in the presence of a hawk."
These cases of chance resemblance should make us unwilling to talk about "mimicry," unless there is actual proof that one or other of the similar species benefits by the resemblance.
These cases, further, throw light on the origin of protective mimicry where it does exist.
Protective mimicry is usually said to have been brought about by the action of natural selection. This is not strictly accurate. Natural selection cannot cause two showy, dissimilar species to resemble one another; all it can do is to seize upon and perfect a resemblance that has been caused by the numerous factors that have co-operated to bring about all the diversity of organic life upon this earth.
_THE GREAT HIMALAYAN BARBET_
Barbets may be described as woodpeckers that are trying to become toucans. The most toucan-like of them all is the great Himalayan barbet (_Megalæma marshallorum_). Barbets are heavily-built birds of medium size, armed with formidable beaks, which they do not hesitate to use for aggressive purposes. As regards the nests they excavate, the eggs they lay, the pad that grows on the hocks of young birds, and their flight, they resemble their cousins the woodpeckers. But they are fruit-eating birds, and not insectivorous; it is this that constitutes the chief difference between them and the woodpeckers. Barbets are found throughout the tropical world. A number of species occur in India. The best known of these is the coppersmith, or crimson-breasted barbet (_Xantholæma hæmatocephala_), the little green fiend, gaudily painted about the head, which makes the hot weather in India seem worse than it really is by filling the welkin with the eternal monotone that resembles the sound of a hammer on a brazen vessel. Nearly as widely distributed are the various species of green barbet (_Thereiceryx_), whose call is scarcely less exasperating than that of the coppersmith, and may be described as the word _kutur_ shouted many times and usually preceded by a harsh laugh or cackle.
The finest of all the barbets are the _Megalæmas_. The great Himalayan barbet attains a length of 13 inches. There is no lack of colour in its plumage. The head and neck are a rich violet blue. The upper back is brownish olive with pale green longitudinal streaks. The lower back and the tail are bright green. The wings are green washed with blue, brown, and yellow. The upper breast is brown, and the remainder of the lower plumage, with the exception of a scarlet patch of feathers under the tail, is yellow with a blue band running along the middle line. This bright red patch under the tail is not uncommon in the bird world, and, curiously enough, it occurs in birds in no way related to one another and having little or nothing in common as regards habits. It is seen in many bulbuls, robins, and woodpeckers, and in the pitta. The existence of these red under tail-coverts in such diverse species can, I think, be explained only on the hypothesis that there is an inherent tendency to variation in this direction in many species.
A striking feature of the great Himalayan barbet is its massive yellow bill, which is as large as that of some species of toucan. Although the bird displays a number of brilliant colours, it is not at all easy to distinguish from its leafy surroundings. It is one of those birds which are heard more often than seen.
Barbets are never so happy as when listening to their own voices. Most birds sing and make a joyful noise only at the nesting season. Not so the barbets; they call all the year round; even unfledged nestlings raise up the voices of infantile squeakiness.
The call of the great Himalayan barbet is very distinctive and easy to recognise, but is far from easy to portray in words. Jerdon described the call as a plaintive _pi-o_, _pi-o_. Hutton speaks of it as _hoo-hoo-hoo_. Scully syllabises it as _till-low_, _till-low_, _till-low_. Perhaps the best description of the note is that it is a mournful wailing, _pee-yu_, _pee-yu_, _pee-yu_. Some like the note, and consider it both striking and pleasant. Others would leave out the second adjective. Not a few regard the cry as the reverse of pleasant, and consider the bird a nuisance. As the bird is always on the move--its call at one moment ascends from the depths of a leafy valley and at the next emanates from a tree on the summit of some hill--the note does not get on one's nerves as that of the coppersmith does. Whether men like its note or not, they all agree that it is plaintive and wailing. This, too, is the opinion of hillmen, some of whom declare that the souls of men who have suffered injuries in the Law Courts, and who have in consequence died of broken hearts, transmigrate into the great Himalayan barbets, and that is why these birds wail unceasingly _un-nee-ow_, _un-nee-ow_, which means "injustice, injustice." Obviously, the hillmen have not a high opinion of our Law Courts!
Himalayan barbets go about in small flocks, the members of which call out in chorus. They keep to the top of high trees, where, as has been said, they are not easily distinguished from the foliage. When perched they have a curious habit of wagging the tail from side to side, as a dog does, but with a jerky, mechanical movement. Their flight is noisy and undulating, like that of a woodpecker. They are said to subsist exclusively on fruit. This is an assertion which I feel inclined to challenge. In the first place, the species remains in the Himalayas all the year round, and fruit must be very scarce there in winter. Moreover, Mr. S. M. Townsend records that a barbet kept by him in captivity on one occasion devoured with gusto a dead mouse that had been placed in its cage. Barbets nest in cavities in the trunks of trees, which they themselves excavate with their powerful beaks, after the manner of woodpeckers. The entrance to the nest cavity is a neat circular hole in a tree at heights varying from 15 to 50 feet. Most birds which rear their broods in holes enter and leave the nest cavity fearlessly, even when they know they are being watched by human beings, evidently feeling that their eggs or young birds are securely hidden away in the heart of the tree. Not so the _Megalæma_. It is as nervous about the site of its nest as a lapwing is. Nevertheless, on one occasion, when the nest of a pair of the great Himalayan barbets was opened out and found to contain an egg and a young bird, which latter was left unmolested, the parent birds continued to feed the young one, notwithstanding the fact that the nest had been so greatly damaged. The eggs are white, like those of all species which habitually nest in holes.
_PART II_ _The Common Birds of the Nilgiris_
_THE COMMON BIRDS OF THE NILGIRIS_
The avifauna of the Nilgiris is considerably smaller than that of the Himalayas. This phenomenon is easily explained. The Nilgiris occupy a far less extensive area; they display less diversity of climate and scenery; the lofty peaks, covered with eternal snow, which form the most conspicuous feature of the Himalayan landscape, are wanting in the Nilgiris.
The birds found in and about a Nilgiri hill station differ in character from those of the plains distant but a score of miles.
Of the common birds of the plains of Madras, the only ones that are really abundant on the Nilgiris are the black crow, the sparrow, the white-eye, the Madras bulbul, the myna, the purple sunbird, the tailor-bird, the ashy wren-warbler, the rufous-backed shrike, the white-browed fantail flycatcher, the Indian pipit, the Indian skylark, the common kingfisher, the pied crested cuckoo, the scavenger vulture, the Pondicherry vulture, the white-backed vulture, the shikra, the spotted dove, and the little brown dove.
The distribution of the avifauna of mountainous countries is largely a matter of elevation. At the base of the Nilgiris all the plains birds of the neighbourhood occur, and most of them extend some way up the hillsides. The majority, however, do not ascend as high as 1000 feet.
At elevations of 3000 feet the avifauna of the hills is already markedly different from that of the plains; nevertheless many of the hill species do not descend to this level, at any rate in the summer.
It is, therefore, necessary, when speaking of a plains bird as occurring or not occurring on the hills, to define precisely what is intended by this expression.
That which follows is written for people who visit the Nilgiri hill stations in the hot weather, and therefore the birds described are those which occur at elevations of 5500 feet and upwards in the summer. Those which visit the hills only in winter are either altogether ignored or given but the briefest mention.
This article does not deal exhaustively with the birds of the Nilgiris; it is merely a short account of the birds commonly seen in the higher regions of those hills during the summer months. To compile an exhaustive list would be easy. I refrain from doing so because a reader unacquainted with Indian ornithology would, if confronted by such a list, find it difficult to identify the common birds.
With this by way of introduction, I will proceed to describe the birds in question, dealing with them according to the classification adopted in the standard book on Indian ornithology--the bird volumes of the "Fauna of British India" series.
THE CORVIDÆ OR CROW FAMILY
This family is not nearly so well represented on the Nilgiris as it is in the Himalayas. The only crow found on the Nilgiris is the Indian corby (_Corvus macrorhynchus_)--the large black crow familiar to persons living in the plains. He, alas, is plentiful in the various hill stations; but it is some consolation that the grey-necked _Corvus_ ceases from troubling those who seek the cool heights.
Like the grey-necked crow, the Indian tree-pie is not found at the Nilgiri hill stations--5000 feet appears to be the highest elevation to which he attains.
Of the tits only one species can be said to be common on the higher Nilgiris: this is the Indian grey tit (_Parus atriceps_)--a striking little bird, smaller than a sparrow. The head, throat, and neck are black, and a strip of this hue runs down the middle of the abdomen. The wings and tail are grey. The cheeks, the sides of the abdomen, and a patch on the back of the head are white. There is also a narrow white bar in the wing, and the grey tail is edged with white. The bird is found all over India, but is far more abundant on the hills than in the plains.
Another tit which, I believe, does not ascend so high as Ootacamund, but which is not uncommon in the vicinity of Coonoor is the southern yellow tit (_Machlolophus haplonotus_). This bird is not, as its name would seem to imply, clothed from head to foot in yellow. Its prevailing hues are green and brown. The head, breast, and upper abdomen are bright yellow, except the crown, crest, a broad streak behind the eye, and a band running from the chin to the abdomen, which are black. It is impossible to mistake this sprightly little bird, which is like the English tom-tit in shape. Tits are arboreal in habits; they seldom descend to the ground. Sometimes they go about in small flocks. They are supposed to live chiefly on insects, but most of them feed on fruit and seeds also, and the grey tit, alas, eats peas, among which it works sad havoc. The inhabitants of the Nilgiris call this last _Puttani kurivi_, which, I understand, means the pea-bird.
THE CRATEROPODIDÆ OR BABBLER FAMILY
This heterogeneous family is well represented in the Nilgiris.
The Madras seven sisters (_Crateropus griseus_) do not ascend the hills to any considerable height. But, of course there are seven sisters in the hills. Every part of India has its flocks of babblers. The Nilgiri babbler is a shy bird; it seems to dislike being watched. One might think it is aware that it is not so beautiful as it might be. But this cannot be the reason, because it has no objection to any person hearing its voice, which may be likened to the squeak of a rusty axle. This Nilgiri babbler does not enter gardens unless they are somewhat unkempt and contain plenty of thick bushes.
_Mirabile dictu_, this shy and retiring bird is none other than the jungle babbler (_Crateropus canorus_)--the common seven sisters or _sath bhai_--which in northern India is as bold and almost as confiding as the robin. No one has attempted to explain why the habits of this species on the Nilgiris should differ so much from those it displays in other places.
The southern scimitar-babbler (_Pomatorhinus horsfieldi_), like the jungle babbler on the Nilgiris, is a bird heard more often than seen.
Every person who has spent any time at Coonoor must be well acquainted with the notes of this species. A common call is a loud _ko-ko-ko-e-e-e_. Sometimes one bird calls _ko-ko-ko_, and another answers _ko-ee_. When the birds are feeding in company, they keep up a continual chatter, which is not unpleasing to the ear. When alarmed they give vent to a harsh cry of a kind characteristic of the babbler tribe. The scimitar-babbler is a bird nearly as big as a myna. It is of brownish hue and has a tail of moderate length. The breast and chin are pure white, and there is a white line running along each side of the head from front to back. The yellow beak is long and curved, hence the adjectival "scimitar." It is impossible to mistake the bird. The difficulty is to obtain anything more than a fleeting glimpse of it. It is so shy that it takes cover the instant it knows that it is being watched. It hops about in thick bushes with considerable address, much as a crow-pheasant does. It feeds on insects, which it picks off the ground or from leaves and trunks of trees. It uses the long bill as a probe, by means of which it secures insects lurking in the crevices of bark.
The Nilgiri laughing-thrush (_Trochalopterum cachinnans_) is a very common bird on the hills. Like the two species of babbler already described, it is a shy creature, living amid thick shrubs, from which it seldom ventures far. The head is slightly crested, the upper plumage, including the wings and tail, is olive brown. The head is set off by a white eyebrow. The under parts are chestnut. The beak and legs are black. Laughing-thrushes congregate in small flocks. They subsist chiefly on fruit. Their cry is loud and characteristic; it may be described as a bird's imitation of human laughter. Their cheerful calls are among the sounds heard most often at Ootacamund and Coonoor.
The Indian white-eye (_Zosterops palpebrosa_) is a bird that has puzzled systematists. Jerdon classed it among the tits, and its habits certainly justify the measure; but later ornithologists have not accepted the dictum "Manners makyth bird," and have placed the white-eye among the babblers.
The white-eye is a plump little bird, considerably smaller than a sparrow. The head and back are yellowish green, becoming almost golden in the sunlight. The wings and tail are brown. The chin, breast, and feathers under the tail are bright yellow, the abdomen is white. Round the eye is a ring of white feathers, interrupted in front by a black patch.
From this ring--its most striking feature--the bird has derived its name. The ring is very regular, and causes the bird to look as though it had been decorating its eye with Aspinall's best enamel.
White-eyes invariably go about in flocks; each member of the company utters unceasingly a cheeping note in order to keep his fellows apprized of his movements. These birds feed largely on insects, which they pick off leaves in truly tit-like manner, sometimes even hanging head downwards in order to secure a morsel.
The beautiful southern green-bulbul (_Chloropsis malabarica_) is numbered among the Crateropodidæ. It is not a true bulbul. It is common on the lower slopes of the Nilgiris, but does not often venture as high as Coonoor. A rich green bulbul-like bird with a golden forehead, a black chin and throat, and a patch of blue on the wing can be none other than this species.
The true bulbuls are also classified among the Crateropodidæ.
My experience is that the common bulbul of the plains--_Molpastes hæmorrhous_, or the Madras red-vented bulbul--is very rarely seen at the Nilgiri hill stations. Jerdon, likewise, states that it ascends the Nilgiris only up to about 6000 feet. Davison, however, declares that the bird begins to get common 4 miles from Ootacamund and is very numerous about Coonoor and all down the ghats. Be this as it may, the Madras red-vented bulbul is not the common bulbul of the Nilgiris. Its sweet notes are very largely, if not entirely, replaced by the yet sweeter and more cheery calls of the hill-bulbul. It will be labour lost to look up this name in Oates's ornithology, because it does not occur in that work. The smart, lively little bird, whose unceasing twittering melody gives our southern hill stations half their charm, has been saddled by men of science with the pompous appellation _Otocompsa fuscicaudata_. Even more objectionable is the English name for the pretty, perky bird. What shall I say of the good taste of those who call it the red-whiskered bulbul, as though it were a seedy Mohammedan who dips his grizzly beard in a pot of red dye by way of beautifying it? I prefer to call this bird the southern hill-bulbul. This name, I admit, leaves something to be desired, because the species is not confined to the hills. It is to be found in most places along the west coast. Nor is it the only bulbul living on the hills. The justification for the name is that if a census were taken of the bird-folk who dwell in our hill stations, it would show that _Otocompsa fuscicaudata_ outnumbered all the crows, mynas, sparrows, flycatchers, and sunbirds put together. It is _the_ bird of the southern hills. Every thicket, every tree--nay, every bush on the hills--has its pair of bulbuls. This species has distinctive plumage. Its most striking feature is a perky crest, which arises from the crown of the head and terminates in a forwardly-directed point, like Mr. Punch's cap. The crest is black and gives the bird a very saucy air. The wings and tail are dark brown, but each feather has a pale edge, which makes a pattern like scales on a fish. Below the eye is a brilliant patch of crimson. A similarly-coloured but larger patch is displayed at the base of the tail. The lower part of the cheek is white; this is divided off from the snowy breast by a narrow black band. The breast is, in its turn, separated from the greyish abdomen by a broad black band, which ornithologists term a collaret. Sometimes the collaret is interrupted in the middle. The hill-bulbul is a most vivacious bird. From dawn to sunset it is an example of perpetual motion. Its vocal cords are as active as its wings. The tinkling sounds of this bulbul form the dominant notes of the bird chorus. Husband and wife almost always move about in company. They flit from tree to tree, from bush to bush, plucking raspberries and other hill fruit as they pass. Bulbuls eat insects, but not when fruit is available. Like all birds bulbuls have large appetites. Recently I saw an Otocompsa devour three wild raspberries within as many minutes, each berry was swallowed at one gulp--a surprising feat, considering the small size of the bird's bill.
A bulbul's nest is a beautifully-shaped cup, usually placed in a bush at about 3 feet from the ground. As a rule, the bulbul selects an exposed site for its nest; in consequence many of the eggs are devoured by lizards. Crows in particular are addicted to young bulbuls, and take full advantage of the simplicity of the parent birds. Probably, three out of four broods never reach maturity. But the bulbul is a philosophic little bird. It never cries over broken eggs. If one clutch is destroyed it lays another.
The yellow-browed bulbul (_Iole icteria_) demands notice in passing, because it is common on the minor ranges. Its upper plumage is greenish yellow, the wings being darker than the back. The lower parts are canary yellow; the bird has also a yellow ring round the eye. Its note has been described as a soft, mellow whistle.
A very different bird is the southern or Nilgiri black bulbul (_Hypsipetes ganeesa_). This is an untidy-looking creature. Its crest is ragged. Its general hue is shabby black or brown, tinged with grey in places. The bill and feet are bright coral red. Black bulbuls utter a variety of notes, most of which are pleasing to the human ear, although they incline to harshness. The birds go about in flocks.
THE SITTIDÆ OR NUTHATCH FAMILY
Nuthatches are little climbing birds characterised by short tails. Like woodpeckers, they feed on insects, which they pick off the trunks and branches of trees. Unlike woodpeckers, however, they move about the trunks of trees with the head pointing indifferently downwards or upwards. The common nuthatch of the Nilgiris is the velvet-fronted blue nuthatch (_Sitta frontalis_). The upper plumage is dark blue, the cock having a velvety-black forehead and a black streak through the eye. The lower parts are creamy white. The bill is coral red. The note is a loud _tee-tee-tee_.
THE DICRURIDÆ OR DRONGO FAMILY
Several species of drongo or king-crow occur on the Nilgiris, but not one of them is sufficiently abundant to be numbered among the common birds of the hill stations.
THE SYLVIIDÆ OR WARBLER FAMILY
Of the warblers it may be said "their name is legion." So many species exist, and the various species are so difficult to differentiate, that the family drives most field ornithologists to the verge of despair. Many of the Indian warblers are only winter visitors to India. Eliminating these, only two warblers are entitled to a place among the common birds of the Nilgiris. These are the tailor-bird and the ashy wren-warbler.
At Coonoor the tailor-bird (_Orthotomus sartorius_) is nearly as abundant as it is in the plains. Oates, be it noted, states that this species does not ascend the hills higher than 4000 feet. As a matter of fact, the tailor-bird does not venture quite up to the plateau, but it is perfectly at home at all elevations below 6000 feet. This species may be likened to a wren that has grown a respectable tail. The forehead is ruddy brown, the back of the head is grey, the back is brown tinged with green. The lower plumage is a pale cream colour. There is a black patch or bar on each side of the neck, visible only when the bird stretches its neck to utter its loud _to-wee_, _to-wee_, _to-wee_. In the breeding season the shafts of the middle pair of tail feathers of the cock grow out beyond the rest. These projecting, bristle-like feathers render the cock easy of identification.
The ashy wren-warbler (_Prinia socialis_) is another "tiny brownie bird." The wings and tail are brown, the remainder of the upper plumage is the colour of ashes, the under parts are cream coloured. This warbler is a slight, loosely-built bird, and is easily distinguished from others of its kind by the curious snapping noise it makes as it flits from bush to bush. It occurs in pairs or singly. Davison remarks that it is "very fond of working its way up to some conspicuous post--to the top of one of the long flower-stalks of _Lobelia excelsa_, for instance--where it will halt for a minute or two, and then, after making a feeble attempt at a song, will dive suddenly in the brushwood and disappear."
THE LANIIDÆ OR SHRIKE FAMILY
Shrikes or butcher-birds are hawks in miniature, as regards habits if not in structure. With the exception of the brown shrike (_Lanius cristatus_), which is merely a winter visitor to India, the rufous-backed shrike (_L. erythronotus_) is the only butcher-bird common on the Nilgiris. The head of this species is pale grey, the back is of ruddy hue. The lower parts are white. The forehead and a broad band running through the eye are black. A bird having a broad black band through the eye is probably a shrike, and if the bird in question habitually sits on an exposed branch or other point of vantage, and from thence swoops on to the ground to secure some insect, the probability of its being a butcher-bird becomes a certainty.
Closely related to the shrikes are the minivets. Minivets are birds of tit-like habits which wander about in small flocks from place to place picking insects from the leaves of trees. They are essentially arboreal birds. I have never seen a minivet on the ground.
The common minivet of the Nilgiris is the orange minivet (_Pericrocotus flammeus_). The head and back of the cock are black. His wings are black and flame-colour, the red being so arranged as to form a band running lengthwise and not across the wing. The tail feathers are red, save the median pair, which are black. During flight the flashing red obliterates the black, so that the moving birds resemble tongues of flame and present a beautiful and striking spectacle. The hen is marked like the cock, but in her the red is replaced by bright yellow. This beautiful bird ceases to be abundant at elevations higher than Coonoor.
THE ORIOLIDÆ OR ORIOLE FAMILY
Both the Indian oriole (_Oriolus kundoo_) and the black-headed oriole (_O. melanocephalus_) occur on the Nilgiris, but on the higher ranges they are nowhere numerous. They therefore merit only passing notice.
THE STURNIDÆ OR STARLING FAMILY
The common myna of the Nilgiris is not _Acridotheres tristis_ but _Æthiopsar fuscus_--the jungle myna. The casual observer usually fails to notice any difference between the two species, so closely do they resemble one another. Careful inspection, however, shows that the jungle myna has a little patch of feathers in front of the head over the beak. _Æthiopsar fuscus_ has all the habits of the common myna. Like the latter, it struts about sedately in company with cattle in order to snatch up the grasshoppers disturbed by the moving quadrupeds. It feeds largely on the insects that infest the capsules of _Lobelia excelsa_, and is often to be seen clinging, like a tit, to the stem in order to secure the insects. Davidson gives these mynas a very bad character, he declares that they do immense damage to the fruit gardens on the Nilgiris, so that without the aid of nets, it is next to impossible to preserve pears from their depredations.
No other species of myna is common on the Nilgiris.
THE MUSCICAPIDÆ OR FLYCATCHER FAMILY
As in the Himalayas so on the Nilgiris the family of flycatchers is well represented. In one small Nilgiri wood I have come across no fewer than six species of flycatcher.
The beautiful little black-and-orange flycatcher (_Ochromela nigrirufa_) is a bird peculiar to the hills of Southern India.
The head and wings of the cock are black, the rest of the body is orange, of deeper hue on the back and breast than on the other parts. The portions of the plumage that are black in the cock are slaty brown in the hen. This flycatcher feeds on insects. But unlike most of its kind, it picks them off the ground more often than it secures them in the air.
It never takes a long flight, and almost invariably perches on a branch not more than two feet above the ground. It emits a low cheeping note--a _chur-r-r_, which is not unlike the sound made by some insects.
The Nilgiri blue-flycatcher (_Stoparola albicaudata_) is stoutly-built and a little larger than a sparrow. The male is clothed from head to tail in dark blue; his wife is more dingy, having a plentiful admixture of brownish grey in her plumage. Blue-flycatchers often occur in little flocks. They have the usual habits of their family, except that they seem sometimes to eat fruit.
A pretty little bird, of which the head, back, tail, and wings are deep blue, and the breast is orange fading into pale yellow towards the abdomen, is Tickell's blue-flycatcher (_Cyornis tickelli_). It has the characteristic habits of its tribe, and continually makes, from a perch, little sallies into the air after flying insects. But, more often than not it starts from one branch, and, having secured its quarry, alights on another. It sings a joyous lay, not unlike that of the fantail-flycatcher, but less sweet and powerful. It nests in a hole in a tree or bank, laying in May two or three eggs very thickly speckled with red spots.
The grey-headed flycatcher (_Culicicapa ceylonensis_) is a bird of somewhat sombre plumage. Its total length is only five inches, and of this half is composed of tail. The head is ashy grey, the back and wings are greenish; the lower plumage is bright yellow, but this is not conspicuous except when the bird is on the wing. This flycatcher has a loud song, which may be syllabised: _Think of me.... Never to be_.
The white-browed fantail-flycatcher (_Rhipidura albifrontata_), which delights the inhabitants of Madras with its cheerful whistle of five or six notes, occurs on the Nilgiris, but is there largely replaced by an allied species--the white-spotted fantail-flycatcher (_R. pectoralis_). The latter has all the habits of the former. Both make the same melody, and each has the habit of spreading out and erecting the tail whenever it settles on a perch after a flight. The white-spotted is distinguishable from the white-browed species by the white eyebrow being much narrower and less conspicuous. It is a black bird with a white abdomen, some white in the wings and tail, a few white spots on the chin, and the white eyebrow mentioned above.
The most beautiful of all the flycatchers is _Terpsiphone paradisi_--the paradise-flycatcher, or ribbon-bird, as it is often called. This is fairly abundant on the Nilgiris. The cock in the full glory of his adult plumage is a truly magnificent object. His crested head is metallic blue-black. This stands out in sharp contrast to the remainder of the plumage, which is as white as snow. Two of his tail feathers, being 12 inches longer than the others, hang down like satin streamers. Young cocks are chestnut instead of white. Birds in both phases of plumage breed. The hen has the metallic blue-black crested head, but she lacks the elongated tail feathers. Her plumage is chestnut, like that of the young cock. In both the hen and the young cock the breast is white. As "Eha" remarks, the hen looks very like a bulbul.
THE TURDIDÆ OR THRUSH FAMILY
This heterogeneous family includes thrushes, chats, robins, accentors, and dippers.
The southern pied bush-chat (_Pratincola atrata_) is one of the commonest and most familiar birds of the Nilgiris. It frequents gardens and is often found near houses: hence it is known as the hill-robin. The cock is clothed in black except the lower part of the back, the under parts, and a bar on the wing, which are white. Those parts that are black in the cock are brown in the hen, while her back and under parts are russet instead of white, but the white bar on the wing persists. This species lives on insects. It dwells in low shrubs and captures its quarry on the ground. It nests in a hole in a bank or well, lining the same with grass or hair. But summer visitors to the hills are not likely to come across the eggs, because these are usually hatched before May.
The Nilgiri blackbird (_Merula simillima_) is very like the blackbird of England. The plumage of the cock, however, is not so black, and the legs, instead of being brown, are reddish. Its charming song, with which all who have visited Ootacamund are familiar, is almost indistinguishable from that of its European cousin.
The Nilgiri thrush (_Oreocincla nilgirensis_) resembles the European thrush in appearance. Its upper plumage is pale brown, spotted with black and buff; its throat and abdomen are white with black drops. This bird has a fine powerful song, but he who wishes to hear it has usually to resort to one of the forests on the plateau of the Nilgiris.
THE PLOCEIDÆ OR WEAVER-BIRD FAMILY
This family includes the weaver-birds, famous for their wonderful hanging retort-shaped nests, and the munias, of which the amadavat or _lal_ is familiar to every resident of India as a cage bird.
The weaver-birds do not ascend the hills, but several species of munia are found on the Nilgiris. Spotted munias (_Uroloncha punctulata_) are abundant in the vicinity of both Coonoor and Ootacamund. They occur in flocks on closely-cropped grassland. They feed on the ground. They are tiny birds, not much larger than white-eyes. The upper plumage is chocolate brown, becoming a rich chestnut about the head and neck, while the breast and abdomen are mottled black and white, hence the popular name. The black spots on the breast and abdomen cause these to look like the surface of a nutmeg grater; for that reason this munia is sometimes spoken of as the nutmeg-bird. The rufous-bellied munia (_Uroloncha pectoralis_) occurs abundantly a little below Coonoor, but does not appear to ascend so high as Ootacamund. Its upper parts are chocolate brown, save the feathers above the tail, which Oates describes as "glistening fulvous." The wings and tail are black, as are the cheeks, chin, and throat. The lower parts are pinkish brown. The stout bill is slaty blue. Like the spotted munia, this species is considerably smaller than a sparrow. |
