The Nests and Eggs of Indian Birds - Part 42

Part 42

I have found them between two leaves, the one forming a high back and turned up at the end to support the bottom of the nest, the other hiding the nest in front and hanging down well below it, the tip only of the first leaf being sewn to the middle of the second. I have found them with four leaves sewn together to form a canopy and sides, from which the bottom of the nest depended bare; and I have found them between two long leaves, whose sides from the very tips to near the peduncles were closely and neatly sewn together. For sewing they generally use cobweb; but silk from coc.o.o.ns, thread, wool, and vegetable fibres are also used.

The eggs vary from three to four in number; but I find that out of twenty-seven nests containing more or less incubated eggs, of which I have notes, exactly two thirds contained only three, and one third four eggs.

About the colour of the eggs there has been some dispute, but this is owing to the birds laying two distinct types of eggs, which will be described below. Hutton's and Jerdon's descriptions of the eggs, _white_ spotted with rufous or reddish brown, are quite correct, but so are those of other writers, who call them _bluish green_, similarly marked. Tickell, who gives them as "pale greenish blue, with irregular patches, especially towards the larger end, resembling dried stains of blood, and irregular and _broken lines scratched round_, forming a zone near the larger end," had of course got hold of the eggs of a _Franklinia_. I have taken hundreds of both types, and I note that, as in the case of _Dicrurus ater_, eggs of the two types are never found in the same nest. All the eggs in each nest always belong to one or the other type.

The parent birds that lay these very different looking eggs certainly do not differ; that I have positively satisfied _myself_.

I quote an exact description of a nest which I took at Bareilly, and which was recorded on the spot:--

"Three of the long ovato-lanceolate leaves of the mango, whose peduncles sprang from the same point, had been neatly drawn together with gossamer threads run through the sides of the leaves and knotted outside, so as to form a cavity like the end of a netted purse, with a wide slit on the side nearest the trunk beginning near the bottom and widening upwards. Inside this, the real nest, nearly 3 inches deep and about 2 inches in diameter, was neatly constructed of wool and fine vegetable fibres, the bottom being thinly lined with horsehair. In this lay three tiny delicate bluish-white eggs, with a few pale reddish-brown blotches at the large ends, and just a very few spots and specks of the same colour elsewhere."

Dr. Jerdon says:--"The Tailor-bird makes its nest with cotton, wool, and various other soft materials, sometimes also lined with hair, and draws together one leaf or more, generally two leaves, on each side of the nest, and st.i.tches them together with cotton, either woven by itself, or cotton-thread picked up, and after pa.s.sing the thread through the leaf, it makes a knot at the end to fix it. I have seen a Tailor-bird at Saugor watch till the native tailor had left the verandah where he had been working, fly in, seize some pieces of the thread that were lying about, and go off in triumph with them; this was repeated in my presence several days running. I have known many different trees selected to build in; in gardens very often a guava-tree. The nest is generally built at from 2 to 4 feet above the ground. The eggs are two, three, or four in number, and in every case which I have seen were white spotted with reddish brown chiefly at the large end.... Layard describes one nest made of cocoanut-fibre entirely, with a dozen leaves of oleander drawn and st.i.tched together.

I cannot call to recollection ever having seen a nest made with more than two leaves.... Pennant gives the earliest, though somewhat erroneous, account of the nest. He says: 'The bird picks up a dead leaf and, surprising to relate, sews it to the side of a living one.'"

I have often seen nests made between many leaves, and I have seen plenty with a dead leaf st.i.tched to a yet living one; but in these points my experience entirely coincides with that of the late Mr. A.

Anderson, whose note I proceed to quote:--

"The dry leaves that are sometimes met with attached to the nest of this species, and which gave rise to the erroneous idea that the bird picks up a dead leaf and, surprising to relate, sews it to the side of a living one, are easily accounted for.

"I took a nest of the Tailor-bird a short time ago" (11th July, 1871) from a brinjal plant (_Solanum esculentum_), which had all the appearance of having had dry leaves attached to it. The nest originally consisted of _three_ leaves, but two of them had been pierced (in the act of pa.s.sing the thread through them) to excess, and had in consequence not only decayed, _but actually separated from the stem of the plant_. These decayed leaves were hanging from the side of the nest by a mere thread, and could have been removed with perfect safety. Perhaps instinct teaches the birds to injure certain leaves in order that they may decay?

"Jerdon says that he does not remember ever having seen a nest made with more than two leaves. I have found the nest of this species vary considerably in appearance, size, and in the number of leaves employed, and, I would also add, in the site selected, as well as in the markings of the eggs, which latter never exceed four in number.

"The nest already described was built hardly _2 feet off the ground_, was rather clumsy (if I might use such an expression), and was composed of _three_ leaves. The eggs were white, covered with brownish-pink blotches almost coalescing at the large end. Another nest, taken in my presence (July, again, which is the general time) from the _very top of a high tree_, was enclosed inside of _one_ leaf, the sides being neatly sewn together, and the cavity at the bottom lined with wool, down, and horsehair. These eggs (four) are covered, chiefly at the larger ends, with minute red spots.

"A third nest seen by me was composed of _seven_ or _eight leaves_".

Captain Hutton tells us that he has seen many nests. All were "composed of cotton, wool, vegetable fibre, and horsehair, formed in the shape of a deep cup or purse, enclosed between two long leaves, the edges of which were sewed to the sides of the nest, in a manner to support it, by threads spun by the bird."

He adds that the birds, though common at their bases, do not ascend the hills; but this is a mistake, for I have repeatedly taken nests at elevations of over 3000 feet; and Mr. Gammie, writing from Sikhim, says:--"We often find nests of this species near my house at Mongphoo (which is at an elevation of about 3500 feet). I took one there on the 16th May, which contained four hard-set eggs. It was in a calicarpa tree and between two of its long ovate leaves, the terminal halves of which were sewn together by the edges, so as to form a purse in which the real nest was placed. Yellow silk of some wild silkworm was the sewing material used."

Again, writing from the Nilgiris, Miss c.o.c.kburn remarks:--"The Tailor-bird is seldom met with on the highest ranges, but appears to prefer the warmer climates enjoyed at the elevation of about 3500 or 4000 feet. They often build in the coffee-trees; a nest now before me was built on a coffee-tree, two of the leaves of which were bent down and sewn together. The threads are of cobweb, and the cavity is lined with the down of seed-pods and fine gra.s.s. At the back of the nest the leaves are made to meet, but are a little apart in front, so as to form an opening for the birds to hop in and out. The depth of the nest inside is 2 inches. It was found in the month of June, and contained four eggs, which were white spotted with light red."

Of its breeding in Nepal, Dr. Scully tells us:--"It breeds freely in the valley at an elevation of 4500 feet. I took many of its nests in the Residency grounds, Rani Jangal, &c., in May, June, and July."

Major C.T. Bingham writes:--"The Indian Tailor-bird breeds in April, May, and June, both at Allahabad and at Delhi. The nest formed of one, two, and occasionally three, leaves neatly sewn so as to form a cone, and lined with the down of the madar, is well known."

Colonel Butler has furnished me with the following note:--

"The Tailor-bird breeds, I fancy, at least twice in the year, as I have seen young birds early in the hot weather both at Mount Aboo and in Deesa, and I have also taken nests in the rains. The nest is usually constructed with much skill and ingenuity. One nest which I took on the 3rd September at Mount Aboo consisted of three leaves cleverly sewn together with raw cotton, leaving a moderate-sized entrance on one side near the top, the inside being lined exclusively with horsehair and fine dry fibres.

"I captured the hen bird with a horsehair noose fixed to the end of a long thin rod as she left the nest. Another nest which I took in Deesa on the 3rd September, 1876, was composed almost entirely of raw cotton with a scanty lining of horsehairs and dry gra.s.s-stems. It was fixed to the outside twigs of a lime-tree, two of the leaves of which were sewn to it; two dead leaves were also attached to the nest, one being sewn on each side as a support to the cotton. It was cup-shaped and open at the top, much like a Chaffinch's nest."

Mr. Oates remarks:--"This is a common bird in Burma in the plains, and possibly also on the hills, though I did not observe it on the latter.

I found the nest of this species containing young birds in the Thayetmyo cantonment on the 12th August. In the Pegu plains it appears to nest from the middle of May to the end of August."

The eggs are typically long ovals, often tapering much towards the small end. The sh.e.l.ls are very thin, delicate, and semi-transparent, and have but little gloss.

The ground-colour is either reddish white or pale bluish green. Of the two types, the reddish white is the more common in the proportion of two to one. The markings consist of bold blotchings or sometimes ill-defined clouds (in this respect recalling the eggs of _Prinia inornata_,) chiefly confined to the large end; and specks, spots, and splashes, extending more or less over the whole surface, typically of a bright brownish red, varying, however, in different examples both in shade and intensity. The markings have a strong tendency to form a bold, irregular zone or cap at the large end, and in some specimens the markings are entirely confined to this portion of the egg's surface.

The eggs, which have a reddish-white ground, though smaller and of a much more elongated shape, closely resemble those of _Suya fuliginosa_.

In length the eggs vary from 06 to 07, and in breadth from 045 to 05; but the average of fifty eggs measured is 064 by 046.

375. Orthotomus atrigularis, Temm. _The Black-necked Tailor-bird_.

Orthotomus atrigularis, _Temm., Hume, cat._ no. 530 bis.

Mr. Mandelli sends me a nest which he a.s.sures me belongs to this species, and the bird he sent me for identification certainly did so belong. The nest was found near the great Ranjit River on the 18th July, and then contained three fresh eggs. The nest, which is a regular Tailor-bird's, composed entirely of the finest imaginable panicle-stems of flowering gra.s.s, is a deep cup placed in between two living leaves, which have been sewn together at the tips and along the margins from the tip for about half their length, so as to provide a perfect pocket in which the nest rests. The leaves of which the pocket is composed were the terminal ones of the twigs of a sapling, and only about 3 feet from the ground. The leaves are large oval ones, each about 7 inches in length; they have been sewn together with wild silk carefully knotted, exactly as is the practice of the common Tailor-bird.

The eggs of this species are not separable from others of _O.

sutorius_, and though they may possibly average somewhat larger, I have not seen enough of them to be able to make sure of this; and as regards shape, colours, and markings the description given of the eggs of _O. sutorius_ applies equally to eggs of this species.

380. Cisticola volitans, Swinh. _The Golden-headed Fantail-Warbler_.

This species was not known to Jerdon, nor was it known to occur in Burma at the time that I issued my Catalogue. Mr. Oates, writing of the breeding of this bird in Southern Pegu, where it is common, says:--"Breeding-operations commence in the middle of May; on the 28th of this month I found two nests, one containing four eggs slightly incubated, and the other two, quite fresh.

"The nest is a small bag about 4 inches in height and 2 or 3 in diameter, with an opening about an inch in diameter near the top. The general shape of the nest is oval. It is composed entirely of the white feathery flowers of the thatch-gra.s.s. The walls of the nest are very thin but strong. The nest is placed about one foot from the ground in a bunch of gra.s.s, and, in the two instances where I found it, against a weed, with one or two leaves of which the materials of the nest were slightly bound.

"The eggs are very glossy pale blue, spotted all over with large and small blotches of rusty brown. I have no eggs of _C. cursitans_ which match them, in that species the spots being always minute and thickly scattered over the sh.e.l.l, whereas in _O. volitans_ the marks are large and fewer in number. Six eggs measured in length from 54 to 57, and in breadth from 42 to 43."

381. Cisticola cursitans (Frankl). _The Rufous Fantail-Warbler_.

Cisticola schoenicola, _Bp., Jerd. B. Ind._ ii, p. 174; _Hume, Rough Draft N. & E._ no. 539.

The Rufous Fantail-Warbler breeds pretty well all over India and Ceylon, confining itself, as far as my experience goes, to the low country, and never ascending the mountains to any great elevation.

The breeding-season lasts, according to locality, from April to October, but it never breeds with us in dry weather, always laying during rainy months. Very likely at the Nicobars, where it rains pretty well all the year round, March being the only fairly dry month, it may breed at all seasons.

I have myself taken several, and have had a great many nests sent to me. With rare exceptions all belonged to one type. The bird selects a patch of dense fine-stemmed gra.s.s, from 18 inches to 2 feet in height, and, as a rule, standing in a moist place; in this, at the height of from 6 to 8 inches from the ground, the nest is constructed; the sides are formed by the blades and stems of the gra.s.s, _in situ_, closely tacked and caught together with cobwebs and very fine silky vegetable fibre. This is done for a length of from 2 to nearly 3 inches, and, as it were, a narrow tube, from 1 to 15 in diameter, formed in the gra.s.s. To this a bottom, from 4 to 6 inches above the surface of the ground, is added, a few of the blades of the gra.s.s being bent across, tacked and woven together with cobwebs and fine vegetable fibre. The whole interior is then closely felted with silky down, in Upper India usually that of the mudar (_Calotropis hamiltoni_). The nest thus constructed forms a deep and narrow purse, about 3 inches in depth, an inch in diameter at top, and 15 at the broadest part below. The tacking together of the stems of the gra.s.s is commonly continued a good deal higher up on one side than on the other, and it is through or between the untacked stems opposite to this that the tiny entrance exists. Of course above the nest the stems and blades of the gra.s.s, meeting together, completely hide it. The dimensions above given are those of the interior of the nest; its exterior dimensions cannot be given. The bird tacks together not merely the few stems absolutely necessary to form a side to the nest, but most of the stems all round, decreasing the extent of attachment as they recede from the nest-cavity. It does this, too, very irregularly; on one side of the nest perhaps no stem more than an inch distant from the interior surface of the nest will be found in any way bound up in the fabric, while on the opposite side perhaps stems fully 3 inches distant, together with all the intermediate ones, will be found more or less webbed together. Occasionally, but rarely, I have found a nest of a different type. Of these one was built amongst the stems of a common p.r.i.c.kly l.a.b.i.ate marsh-plant which has white and mauve flowers. There was a straggling framework of fine gra.s.s, firmly netted together with cobwebs, and a very scanty lining of down. The nest was egg-shaped, and the aperture on one side near the top. Mr. Brooks, I believe, once obtained a similar one; but the vast majority of the others that any of us have ever got have been of the type first described, which corresponds closely with Pa.s.sler's account.

Five is the usual complement of eggs; at any rate I have notes of more than a dozen nests that contained this number, and in more than half the cases the eggs were partly incubated. I have no record of more than five, and though I have any number of notes of nests containing one, two, three, and four eggs, yet these latter in almost all these cases were fresh.

Mr. Blyth says that this species is "remarkable for the beautiful construction of its nest, _sewing_ together a number of growing stems and leaves of gra.s.s, with a delicate pappus which forms also the lining, and laying four or five translucent white eggs, with reddish-brown spots, more numerous and forming a ring at the large end, very like those of _Orthotomus sutorius_. It abounds in suitable localities throughout the country."

I must here note that Mr. Blyth never paid special attention to eggs, or he would have hardly said this, because the character of the markings are essentially different. Those of the Tailor-bird are typically _blotchy_, of the present species _speckly_.

Colonel W. Vincent Legge writes to me from Ceylon that "in the Western Province it breeds from May until September, and constructs its nest either in paddy-fields or in guinea-gra.s.s plots attached to bungalows."

The nest is so beautiful and so neatly constructed that perhaps a short description of it will not be out of place. A framework of cotton or other fibrous material is formed round two or three upright stalks, about 2 feet from the ground, the material being sewn into the gra.s.s and pa.s.sed from one stalk to the other until a complete net is made. This takes the bird from one to two days to construct[A].

Several blades, belonging to the stalks round which the cotton is pa.s.sed, are then bent down and interlaced across to form a bottom on which, and inside the cotton network, a neat little nest of fine strips of gra.s.s torn off from the blade is built; this is most beautifully lined with cotton or other downy substance, which appears to be plastered with the saliva of the bird, until it takes the appearance and texture of soft felt.

[Footnote A: Numbers of these birds used to build in a guinea-gra.s.s field attached to my bungalow at Colombo, and I had full opportunity of watching the construction of the nest on many occasions.--W.V.L.]

"The average dimensions of the interior or cup are 2 inches in depth by 1 in breadth. The whole structure is generally completed in about five days, and the first egg laid on the fifth or sixth day from the commencement. The number of eggs varies from two to four, most nests containing three. The time of incubation is, as a rule, from nine to eleven days.
