The paradise flycatchers leave Northern India and migrate southwards a few weeks after the young birds have left the nest.
Numbers of bulbuls" nests are likely to be found in July, but the breeding time of these birds is rapidly drawing to its close. Sparrows and doves are of course engaged in parental duties; their eggs have been taken in every month of the year.
The nesting season is now at its height for the white-necked storks, the koels and their dupes--the house-crows, also for the various babblers and their deceivers--the brain-fever birds and the pied crested cuckoos. The tailor-birds, the ashy and the Indian wren-warblers, the brahminy mynas, the wire-tailed swallows, the amadavats, the sirkeer cuckoos, the pea-fowl, the water-hens, the common and the pied mynas, the cuckoo-shrikes and the orioles are all fully occupied with nursery duties. The earliest of the brain-fever birds to be hatched have left the nest. Like all its family the young hawk-cuckoo has a healthy appet.i.te. In order to satisfy it the unfortunate foster-parents have to work like slaves, and often must they wonder why nature has given them so voracious a child. When it sees a babbler approaching with food, the cuckoo cries out and flaps its wings vigorously. Sometimes these completely envelop the parent bird while it is thrusting food into the yellow mouth of the cuckoo.
The breast of the newly-fledged brain-fever bird is covered with dark brown drops, so that, when seen from below, it looks like a thrush with yellow legs. Its cries, however, are not at all thrushlike.
Many of the wire-tailed swallows, minivets and white-browed fantail flycatchers bring up a second brood during the rains. The loud cheerful call of the last is heard very frequently in July.
Numbers of young bee-eaters are to be seen hawking at insects; they are distinguishable from adults by the dullness of the plumage and the fact that the median tail feathers are not prolonged as bristles.
Very few crows emerge from the egg before the 1st of July, but, during the last week in June, numbers of baby koels are hatched out. The period of incubation for the koel"s egg is shorter than that of the crow, hence at the outset the baby koel steals a march on his foster-brothers. Koel nestlings, when they first emerge from the egg, differ greatly in appearance from baby crows. The skin of the koel is black, that of crow is pink for the first two days of its existence, but it grows darker rapidly. The baby crow is the bigger bird and has a larger mouth with fleshy sides. The sides of the mouth of the young koel are not fleshy. The neck of the crow nestling is long and the head hangs down, whereas the koel"s neck is short and the bird carries its head huddled in its shoulders. Crows nest high up in trees, these facts are therefore best observed by sending up an expert climber with a tin half-full of sawdust to which a long string is attached. The climber lets down the eggs or nestlings in the tin and the observer can examine them in comfort on _terra firma_. The parent crows do not appear to notice how unlike the young koels are to their own nestlings, for they feed them most a.s.siduously and make a great uproar when the koels are taken from the nest. Baby crows are noisy creatures; koels are quiet and timid at first, but become noisier as they grow older.
The feathers of crow nestlings are black in each s.e.x. Young koels fall into three cla.s.ses: those of which the feathers are all black, those of which a few feathers have white or reddish tips, those which are speckled black and white all over because each feather has a white tip. The two former appear to be young c.o.c.ks and the last to be hens.
Baby koels, in addition to hatching out before their foster-brethren, develop more quickly, so that they leave the nest fully a week in advance of the young corvi. After vacating the nest they squat for some days on a branch close by; numbers of them are to be seen thus in suitable localities towards the end of July. At first the call of the koel is a squeak, but later it takes the form of a creditable, if ludicrous, attempt at a caw. The young cuckoo does not seem to be able to distinguish its foster-parents from other crows; it clamours for food whenever any crow comes near it.
Of the scenes characteristic of the rains in India none is more pleasing than that presented by a colony of nest-building bayas or weaver-birds (_Ploceus baya_). These birds build in company. Sometimes more than twenty of their wonderful retort-like nests are to be seen in one tree. This means that more than forty birds are at work, and, as each of these indulges in much cheerful twittering, the tree in question presents an animated scene. Both s.e.xes take part in nest-construction.
Having selected the branch of a tree from which the nest will hang, the birds proceed to collect material. Each completed nest contains many yards of fibre not much thicker than stout thread. Such material is not found in quant.i.ty in nature. The bayas have, therefore, to manufacture it. This is easily done. The building weaver-bird betakes itself to a clump of elephant-gra.s.s, and, perching on one of the blades, makes a notch in another near the base. Then, grasping with its beak the edge of this blade above the notch, the baya flies away and thus strips off a narrow strand. Sometimes the strand adheres to the main part of the blade at the tip so firmly that the force of the flying baya is not sufficient to sever it. The bird then swings for a few seconds in mid-air, suspended by the strip of leaf. Not in the least daunted the baya makes a fresh effort and flies off, still gripping the strand firmly. At the third, if not at the second attempt, the thin strip is completely severed. Having secured its prize the weaver-bird proceeds to tear off one or two more strands and then flies with these in its bill to the nesting site, uttering cries of delight. The fibres obtained in this manner are bound round the branch from which the nest will hang. More strands are added to form a stalk; when this has attained a length of several inches it is gradually expanded in the form of an umbrella or bell. The next step is to weave a band of gra.s.s across the mouth of the bell. In this condition the nest is often left unfinished. Indians call such incomplete nests _jhulas_ or swings; they a.s.sert that these are made in order that the c.o.c.ks may sit in them and sing to their mates while these are incubating the eggs. It may be, as "Eha" suggests, that at this stage the birds are dissatisfied with the balance of the nest and for this reason leave it. If the nest, at this point of its construction, please the weaver-birds they proceed to finish it by closing up the bell at one side of the cross-band to form a receptacle for the eggs, and prolonging the other half of the bell into a long tunnel or neck. This neck forms the entrance to the nest; towards its extremity it becomes very flimsy so that it affords no foothold to an enemy. Nearly every baya"s nest contains some lumps of clay attached to it. Jerdon was of opinion that the function of these is to balance the nest properly. Indians state that the bird sticks fireflies into the lumps of clay to light up the nest at night. This story has found its way into some ornithological text-books. There is no truth in it.
The present writer is inclined to think that the object of these lumps of clay is to prevent the light loofah-like nest swinging too violently in a gale of wind.
Both s.e.xes take part in nest-construction. After the formation of the cross-bar at the mouth of the bell one of the birds sits inside and the other outside, and they pa.s.s the strands to each other and thus the weaving proceeds rapidly. While working at the nest the bayas, more especially the c.o.c.ks, are in a most excited state. They sing, scream, flap their wings and snap the bill. Sometimes one c.o.c.k in his excitement attacks a neighbour by jumping on his back! This results in a fight in which the birds flutter in the air, pecking at one another.
Often the combatants "close" for a few seconds, but neither bird seems to get hurt in these little contests.
Every bird-lover should make a point of watching a company of weaver-birds while these are constructing their nests. The tree or trees in which they build can easily be located by sending a servant in July to search for them. The favourite sites for nests in the United Provinces seem to be babul trees that grow near borrow pits alongside the railroad.
In the rainy season two other birds weave nests, which are nearly as elegant as those woven by the baya. These birds, however, do not nest in company. They usually build inside bushes, or in long gra.s.s.
For this reason they do not lend themselves to observation while at work so readily as bayas do. The birds in question are the Indian and the ashy wren-warbler.
The former species brings up two broods in the year. One, as has been mentioned, in March and the other in the "rains."
The nest of the Indian wren-warbler (_Prinia inornata_) is, except for its shape and its smaller size, very like that of a weaver-bird. It is an elongated purse or pocket, closely and compactly woven with fine strips of gra.s.s from 1/40 to 1/20 inch in breadth. The nest is entered by a hole near the top. Both birds work at the nest, clinging first to the neighbouring stems of gra.s.s or twigs, and later to the nest itself when this has attained sufficient dimensions to afford them foothold.
They push the ends of the gra.s.s in and out just as weaver-birds do.
Like the baya, the Indian wren-warbler does not line its nest. The eggs are pale greenish-blue, richly marked by various shades of deep chocolate and reddish-brown. As Hume remarks: "nothing can exceed the beauty or variety of markings, which are a combination of bold blotches, clouds and spots, with delicate, intricately woven lines, recalling somewhat ... those of our early favourite--the yellow-hammer."
The ashy wren-warbler (_Prinia socialis_) builds two distinct kinds of nest. One is just like that of the tailor-bird, being formed by sewing or cobbling together two, three, four or five leaves, and lining the cup thus formed with down, wool, cotton or other soft material. The second kind of nest is a woven one. This is a hollow ball with a hole in the side. The weaving is not so neat as that of the baya and the Indian wren-warbler. Moreover, several kinds of material are usually worked into the nest, which is invariably lined.
The building of two totally different types of nest is an interesting phenomenon, and seems to indicate that under the name _Prinia socialis_ are cla.s.sed two different species, which anatomically are so like one another that systematists are unable to separate them. Both kinds of nests are found in the same locality and at the same time of the year. Against the theory that there are two species of ashy wren-warbler is the fact that there is no difference in appearance between the eggs found in the two kinds of nest. All eggs are brick-red or mahogany colour, without any spots or markings.
Many of the Indian cliff-swallows, of which the nests are described in the calendar for March, bring up a second brood in the "rains."
Needless to state that in the monsoon the tank and the _jhil_ are the happy hunting grounds of the ornithologist.
In July and August not less than thirty species of waterfowl nidificate. Floating nests are constructed by sarus cranes, purple coots and the jacanas. The various species of egrets breed in colonies in trees in some village not far from a tank; in company with them spoonbills, cormorants, snake-birds, night-herons and other birds often nest. The white-breasted waterhen constructs its nursery in a thicket at the margin of some village pond. The resident ducks are also busy with their nests. These are in branches of trees, in holes in trees or old buildings, or on the ground.
When describing the nesting operations of waterfowl in Northern India it is difficult to apportion these between July and August, for the eggs of almost all such species are as likely to be found in the one month as in the other. A few individuals begin to lay in June, the majority commence in July, but a great many defer operations until August. There is scarcely an aquatic species of which it can be said: "It never lays before August." Nor are there many of which it can be a.s.serted: "Their eggs are never found after July."
Individuals differ in their habit. A r.e.t.a.r.ded monsoon means that the water-birds begin to nest later than usual. The first fall of the monsoon rain seems to be the signal for the commencement of nesting operations, but by no means every pair of birds obeys the signal immediately.
The nearest approach to a generalisation which it is possible to make is that the egrets and paddy-birds are usually the first of the monsoon breeders to begin nest-building, while the spot-billed duck, the whistling teal and the bronze-winged jacana are the last. In other words, the eggs of the former are most likely to be found in July and those of the latter in August.
As the calendar for this month has already attained considerable dimensions, a description of the nests of all these water-birds is given in the August calendar. It is, however, necessary to state that the eggs of the following birds are likely to be found in July: purple coot, common coot, bronze-winged and pheasant-tailed jacana, black ibis, white-necked stork, cormorant, snake-bird, cotton teal, comb duck, spot-billed duck, spoonbill, and the various herons and egrets.
AUGUST
See! the flushed horizon flames intense With vivid red, in rich profusion streamed O"er heaven"s pure arch. At once the clouds a.s.sume Their gayest liveries; these with silvery beams Fringed lovely; splendid those in liquid gold, And speak their sovereign"s state. He comes, behold!
MALLET.
The transformation scene described in July continues throughout August. Torrential rain alternates with fierce sunshine. The earth is verdant with all shades of green. Most conspicuous of these are the yellowish verdure of the newly-transplanted rice, the vivid emerald of the young plants that have taken root, the deeper hue of the growing sugar-cane, and the dark green of the mango topes.
Unless the monsoon has been unusually late in reaching Northern India the autumn crops are all sown before the first week in August. The sugar-cane is now over five feet in height. The cultivators are busily transplanting the better kinds of rice, or running the plough through fields in which the coa.r.s.er varieties are growing.
The aloes are in flower. Their white spikes of drooping tulip-like flowers are almost the only inflorescences to be seen outside gardens at this season of the year. The mango crop is over, but that of the pineapples takes its place.
At night-time many of the trees are illumined by hundreds of fireflies. These do not burn their lamps continuously. Each insect lets its light shine for a few seconds and then suddenly puts it out.
It sometimes happens that all the fireflies in a tree show their lights and extinguish them simultaneously and thereby produce a luminous display which is strikingly beautiful. Fireflies are to be seen during the greater part of the year, but they are far more abundant in the "rains" than at any other season.
As in July so in August the voices of the birds are rarely heard after dark. The nocturnal music is now the product of the batrachian band, ably seconded by the crickets.
During a prolonged break in the rains the frogs and toads are hushed, except in _jhils_ and low-lying paddy fields. Cessation of the rain, however, does not silence the crickets.
The first streak of dawn is the signal for the striking up of the jungle and the spotted owlets. Hard upon them follow the koels and the brain-fever birds. These call only for a short time, remaining silent during the greater part of the day. Other birds that lift up their voices at early dawn are the crow-pheasant, the black partridge and the peac.o.c.k. These also call towards dusk. As soon as the sun has risen the green barbets, coppersmiths, white-breasted kingfishers and king-crows utter their familiar notes; even these birds are heard but rarely in the middle of the day, nor have their voices the vigour that characterised them in the hot weather. Occasionally the brown rock-chat emits a few notes, but he does so in a half-hearted manner.
In the early days of August the magpie-robins sing at times; their song, however, is no longer the brilliant performance it was. By the end of the month it has completely died away.
The Indian cuckoo no more raises its voice in the plains, but the pied crested-cuckoo continues to call l.u.s.tily and the pied starlings make a joyful noise. The oriole"s liquid _pee-ho_ is gradually replaced by the loud _tew_, which is its usual cry at times when it is not nesting.
The water-birds, being busy at their nests, are of course noisy, but, with the exception of the loud trumpeting of the sarus cranes, their vocal efforts are heard only at the _jhil_.
The did-he-do-its, the rollers, the bee-eaters, two or three species of warblers and the perennial singers complete the avian chorus.
Numbers of rosy starlings are returning from Asia Minor, where they have reared up their broods. The inrush of these birds begins in July and continues till October. They are the forerunners of the autumn immigrants. Towards the end of the month the garganey or blue-winged teal (_Querquedula circia_), which are the earliest of the migratory ducks to visit India, appear on the tanks. Along with them comes the advance-guard of the snipe. The pintail snipe (_Gallinago stenura_) are invariably the first to appear, but they visit only the eastern parts of Northern India. Large numbers of them sojourn in Bengal and a.s.sam. Stragglers appear in the eastern portion of the United Provinces; in the western districts and in the Punjab this snipe is a _rara avis_. By the third week in August good bags of pintail snipe are sometimes obtained in Bengal. The fantail or full-snipe (_G.
coelestis_) is at least one week later in arriving. This species has been shot as early as the 24th August, but there is no general immigration of even the advance-guard until quite the end of the month.
The jack-snipe (_G. gallinula_) seems never to appear before September.
Most of the monsoon broods of the Indian cliff-swallow emerge from the eggs in August. The "rains" breeding season of the amadavats or red munias is now over, and the bird-catcher issues forth to snare them.
His stock-in-trade consists of some seed and two or three amadavats in one of the pyramid-shaped wicker cages that can be purchased for a few annas in any bazaar. To the base of one of the sides of the cage a flap is attached by a hinge. The flap, which is of the same shape and size as the side of the cage, is composed of a frame over which a small-meshed string net is stretched. A long string is fastened to the apex of the flap and pa.s.sed through a loop at the top of the cage.
Selecting an open s.p.a.ce near some tall gra.s.s in which amadavats are feeding, the bird-catcher sets down the cage and loosens the string so that the flap rests on the earth. Some seed is sprinkled on the flap.
Then the trapper squats behind a bush, holding the end of the string in his hand. The cheerful little _lals_ inside the cage soon begin to twitter and sing, and their calls attract the wild amadavats in the vicinity. These come to the cage, alight on the flap, and begin to eat the seed. The bird-catcher gives the string a sharp pull and thus traps his victims between the flap and the side of the cage. He then disentangles them, places them in the cage, and again sets the trap.
Almost all the birds that rear up their young in the spring have finished nesting duties for the year by August. Here and there a pair of belated rollers may be seen feeding their young. Before the beginning of the month nearly all the young crows and koels have emerged from the egg, and the great majority of them have left the nest. Young house-crows are distinguished from adults by the indistinctness of the grey on the neck. They continually open their great red mouths to clamour for food.
The wire-tailed swallows, swifts, pied crested-cuckoos, crow-pheasants, butcher-birds, cuckoo-shrikes, fantail flycatchers, babblers, white-necked storks, wren-warblers, weaver-birds, common and pied mynas, peafowl, and almost all the resident water-birds, waders and swimmers, except the terns and the plovers, are likely to have eggs or young. The nesting season of the swifts and butcher-birds is nearly over. In the case of the others it is at its height. The wire-tailed swallows and minivets are busy with their second broods.
