Part 70

The nests sent by Mr. Blewitt are regular Tailor-birds' nests, composed chiefly of very fine grass, about the thickness of fine human hair, with no special lining, carefully sewn with cobwebs, silk from cocoons, or wool, into one or two leaves, which often completely envelop it, so as to leave no portion of the true nest visible.

The eggs belong to at least two very distinct types. Both are typically rather slender ovals, a good deal compressed towards one end; but in both somewhat broader and more or less pyriform varieties occur. In both the shell is exquisitely fine and glossy; in some specimens it is excessively glossy. In both the ground-colour is a very delicate pale greenish blue, occasionally so pale that the ground is all but white--in one type entirely unspeckled and unspotted, in the other finely and thickly speckled everywhere, and towards the large end more or less spotted, with brownish or purplish red. The markings are densest towards the large end, where they either actually form, or exhibit a strong tendency to form, a more or less conspicuous speckled, semi-confluent zone.

Out of fifty-six eggs, twenty-one belong to the latter type. As in Dicrurus ater, the two types never appear to be found in the same nest; but the nests in which the two types are found are precisely similar, and the parent birds are identical.

In length the eggs vary from 0·53 to 0·62, and in width from 0·4 to 0·45; but the average of fifty-six eggs is 0·58 by 0·42. There is no difference whatever in the size of the two types.

Prinia beavani, Wald., Hume, cat. no. 538 bis.

Mr. Oates, who found the nest of this Warbler in Pegu, says:--"June 29th. Found a nest sewn into a broad soft leaf of a weed in forest about 2 feet from the ground. The edges of the leaf are drawn together and fastened by white vegetable fibres. The nest is composed entirely of fine grass, no other material entering into its composition. For further security the nest is stitched to the leaves in a few places; the depth of the nest is about 3 inches, and internal diameter all the way down about 1½. Eggs three, very glossy, pale blue, with specks and dashes of pale reddish brown, chiefly at the larger end, where they form a cap. Size ·58, ·62, ·61, by ·47."

Mr. Mandelli sends me a regular Tailor-bird's nest as that of this species. It was found below Yendong in Native Sikhim on the 1st May, and contained three fresh eggs. The nest itself is a beautiful little cup, composed of silky vegetable down and excessively fine grass-stems, and a very little black hair firmly felted together, and is placed between two living leaves of a sapling neatly sewn together at the margins with bright yellow silk.

The eggs are rather elongated, very regular ovals. The shell stout for the size of the egg, but very fine and compact, and with a moderate gloss. The ground-colour is a very delicate pale greenish blue. At or round the larger end there is very generally a mottled cap or zone (more commonly the latter) of duller or brighter brownish red, while irregular blotches, streaks, spots, and specks of the same colour, but usually a slightly paler shade, are more or less sparsely scattered over the rest of the surface of the egg, sometimes they are almost wholly wanting. Occasionally the zone is at the small end.

The eggs measure from 0·60 to 0·62 in length, by 0·43 to 0·48 in breadth; but the average of six eggs is 0·61 by 0·45.

384. Franklinia buchanani (Blyth). The Rufous-fronted Wren-Warbler.

Franklinia buchanani (Blyth), Jerd. B. Ind. ii, p. 186; Hume, Rough Draft N. & E. no. 551.

The Rufous-fronted Wren-Warbler breeds throughout Central India, the Central Provinces, the North-western Provinces, the Punjab, and Rajpootana. It affects chiefly the drier and warmer tracts, and, though said to have been obtained in the Nepal Terai, has never been met with by me either there or in any very moist, swampy locality. The breeding-season extends from the end of May until the beginning of September.

The nests, according to my experience, are always placed at heights of from a foot to 4 feet from the ground, in low scrub-jungle or bushes. They vary greatly in size and shape, according to position. Some are oblate spheroids with the aperture near the top, some are purse-like and suspended, and some are regular cups. One of the former description measured externally 5 inches in diameter one way by 3¼ inches the other. One of the suspended nests was 7 inches long by 3 wide, and one of the cup-shaped nests was nearly 4 inches in diameter and stood, perhaps, at most 2½ inches high. The egg-cavity in the different nests varies from 1¾ to 2¼ inches in diameter, and from less than 2 to fully 3 inches in depth. Externally the nest is very loosely and, generally, raggedly constructed of very fine grass-stems and tow-like vegetable fibre used in different proportions in different nests; those in which grass is chiefly used being most ragged and straggling, and those in which most vegetable fibre has been made use of being neatest and most compact. In all the nests that I have seen the egg-cavity has been lined with something very soft. In many of the nests the lining is composed of small felt-like pieces of some dull salmon-coloured fungus, with which the whole interior is closely plastered; in others there is a dense lining of soft silky vegetable down; and in others the down and fungus are mingled. They lay from four to five eggs, never more than this latter number according to my experience.

"At the end of June 1867," writes Mr. Brooks, "I took two nests of this bird at Chunar in low ber bushes about 2 feet from the ground. They were little spheres of fine grass with a hole at the side. One contained four eggs; these were of a greyish-white ground or nearly pure white, finely speckled over with reddish brown, some of the eggs exhibiting a tendency to form a zone round the large end, and others with a complete zone."

"At Sambhur," Mr. Adam says, "this Wren-Warbler is always found wherever there are low bushes. It breeds just before the rains, but I have not recorded the date. I had a nest with the bird and five eggs sent to me. The eggs are pale bluish white, with reddish-brown spots and freckles all over them."

"During July, August, and the early part of September," remarks Mr. W. Blewitt, "I found a great number of the nests and eggs of this bird in the jungle-preserves of Hansie and its neighbourhood. The nests, of which I have already sent you several, were mostly in ber (Zizyphus jujuba) and hinse (Capparis aphylla) bushes, at heights of from 3 to 4 feet from the ground. Five was the largest number of eggs that I found in any one nest."

Major C.T. Bingham remarks:--"I found several nests of this bird in the beginning of October at Delhi in the jherberry bushes so plentiful on the Ridge. Both nests and eggs are very like those of Cisticola cursitans before described; the only difference I could find was that the entrance in the nest of C. cursitans that I found was at the top, and in all the nests of F. buchanani at the side rather low down; the nests of the latter are also firmer and more globular in shape. The eggs are, to my eye, identical in colour and form."

Mr. G. Reid informs us that at Lucknow it is fairly common and a permanent resident. It makes an oblong, loosely constructed nest with the aperture near the top, and lays three or four white eggs minutely spotted with dingy red.

Mr. J. Davidson writes that in Western Khandeish this Warbler is the commonest bird, breeding about Dhulia in July, August, and September.

Colonel E.A. Butler writes:--"I found a nest of the Rufous-fronted Wren-Warbler at Deesa on the 27th July, 1875. It was in a grass beerh, and placed in a heap of dead thorns overgrown with grass and about a foot from the ground. It was composed externally of dry grass-stems, with lumps of silky white vegetable down (Calotropis) scattered sparingly over the whole nest. The lining consisted of very fine dry grass neatly put together and felted with silky down, and a considerable amount of the dull salmon-coloured fungus or lichen referred to in the 'Rough Draft of Nests and Eggs,' p. 359. In shape the nest is nearly spherical, being slightly oval however, with a small aperture near the top. The entrance was 1½ inches in diameter, and the nest itself roughly measured from the outside 4½ inches in length and 4 in width. The eggs, usually four in number, are white, closely speckled over with pale rusty red, intermingled with a few pale washed-out inky markings, in some cases at the large end, which is surrounded by a zone clear and well-marked in some instances, less distinct in others. I found other nests in the same neighbourhood as below:--

"Aug. 24, 1875. A nest containing 4 fresh eggs. July 20, 1876. " " 4 " " July 28, " " " 4 young birds. Aug. 4, " " " 4 fresh eggs. Aug. 5, " " " 4 " " Aug. 5, " " " 4 " " Aug. 5, " " " 5 " " Aug. 8, " " " 5 " " Aug. 14, " " " 5 " "

"In every one of the above instances the nest was exactly similar to the one I have described, and built in the same kind of situation, i.e. in heaps of dead thorns overgrown with long grass. The eggs are all much the same, the spots being larger in some than in others and more numerous in some cases than in others. In one set I have the ground is very pale bluish white (skimmed milk) instead of being pure white. As a rule the eggs are almost exactly like the eggs of C. cursitans, and if mixed I doubt very much if any person could separate them. On examining the salmon-coloured fungus-lining it appears to me to be nothing more nor less than small pieces of dried ber leaves, and I have never examined a nest without finding some of this material at the bottom of it."

"The Rufous-fronted Wren-Warbler," writes Lieut. Barnes, "breeds in Rajpootana during July, August, and the early part of September. The nest, composed of grass, is loosely constructed, and placed in low bushes or scrub."

The eggs vary somewhat in size and shape; a moderately broad oval, slightly compressed towards the larger end, being, however, the commonest type. Examining a large series, it appears that variations from this type are more commonly of an elongated than a spherical form. The eggs are of the same character as those of Cisticola cursitans (p. 236), but yet differ somewhat. The eggs are many of them fairly glossy, the shells very delicate and fragile; the ground-colour white, usually slightly greyish, but in some specimens faintly tinged with very pale green or pink. Typically they are very thickly and very finely speckled all over with somewhat dingy red or purplish red. In three out of four eggs the markings are densest and largest towards the large end; and, to judge from the large series before me, at least one in four exhibits a more or less well-defined mottled zone or cap at this end, formed by the partial confluence of multitudinous specks.

In some specimens the markings are pale inky purple, and in some slightly purplish brown, but these are abnormal varieties. In one or two eggs fairly-sized spots and blotches are intermingled with the minute specklings, but this also is rare. Of course in different specimens the density of the speckling varies greatly: in some eggs not a fifth of the surface is covered with the markings, while in some it appears as if there were more of these than of the ground-colour.

In length the eggs vary from 0·55 to 0·66, and in breadth from 0·43 to 0·52; but the average of eighty-seven eggs is 0·62 by 0·48.
