Part 65

From Sikhim, Mr. Gammie writes:--"I found two nests of the Scaly-breasted Wren this year within a few yards of each other. They were in a small moist ravine in the Rishap forest, at 5000 feet above sea-level. One was deserted before being quite finished, and the other was taken a few days after three eggs had been laid. The two nests were alike, and both were built among the moss growing on the trunks of large trees, within a yard of the ground. The only carried material was very fine roots, which were firmly interwoven, and the ends worked in with the natural moss. These fine roots were worked into the shape of a half-egg, cut lengthways, and placed with its open side against the trunk, which thus formed one side of the nest. Near the top one side was not quite close to the trunk, and by this irregular opening the bird entered. Internally the nest measured 3 inches deep by 2 in width. I killed the female off the eggs; she had eaten a caterpillar, spiders, and other insects."

Mr. Mandelli found a nest of this species at Pattabong, elevation 5000 feet, near Darjeeling, on the 19th May, containing three fresh eggs. The nest was placed amongst some small bushes projecting out of a crevice of a rock about three feet from the ground. It was completely sheltered above, but was not hooded or domed; it was, for the size of the bird, a rather large cup, composed of green moss rather closely felted together and lined with fine blackish-brown roots. The cavity measured about 2 inches in diameter and 1 in depth.

The eggs of this species seem large for the size of the bird; they are rather broad at the large end, considerably pointed towards the small end. They are pure white, almost entirely devoid of gloss, and with very delicate and fragile shells.

The eggs varied from in 0·72 to 0·78 in length, and from 0·54 to 0·57 in breadth.

All I know of the nidification of this species is that Sir E.C. Buck, C.S., found a nest at Rogee, in the Sutlej Valley, on the 8th June, on the end of a deodar branch 8 feet from the ground and partly suspended. It contained seven young birds fully fledged; no crest or signs of a crest were observable in the young. Both the parent birds and the nest were kindly sent to me.

The nest is a deep pouch suspended from several twigs, with the entrance at the top, and composed entirely of fine lichens woven or intervened into a thick, soft, flexible tissue of from three eighths to half an inch in thickness. Externally the nest was about 3½ to 4 inches in depth, and about 3 inches in diameter.

Both Mr. Brooks and Captain Cock succeeded in securing the nests and eggs of the Indian Great Reed-Warbler in Cashmere. Common as it is, my own collectors failed to get eggs, though they brought plenty of nests.

The nest is a very deep massive cup hung to the sides of reeds. A nest before me, taken in Cashmere on the 10th June, is an inverted and slightly truncated cone. Externally it has a diameter of 3¼ inches and a depth of nearly 6 inches. It is massive, but by no means neat; composed of coarse water-grass, mingled with a few dead leaves and fibrous roots of water-plants. The egg-cavity is lined with finer and more compactly woven grass, and measures about 1¾ inch in diameter and 2¼ inches in depth.

It breeds in May and June; at the beginning of July all the nests either contained young or were empty. Four is the full complement of eggs.

Mr. Brooks noted in epist.:--"Srinuggur, 10th June. I went out early this morning on the lake here to look for eggs of Acrocephalus stentoreus, but it came on to rain so heavily that I only partially succeeded. I took three nests, two with three eggs each, and one with four young ones, the latter half-hatched. The eggs very much resemble large and boldly-marked Sparrows' eggs. They are smaller than the eggs of A. arundinaceus, but very similar. The latter have larger clear spaces without spots than those of our bird. I neither saw nor heard any other aquatic warbler."

Later, in a paper on the eggs and nests he had obtained in Cashmere, he stated that this species "breeds abundantly in the Cashmere lakes. The nest is supported, about 18 inches above the water, by three or four reeds, and is a deep cup composed of grasses and fibres. The eggs are four, very like those of A. arundinaceus, but the markings are more plentiful and smaller."

Captain Cock writes to me that "the Large Reed-Warbler is very common in the reeds that fringe all the lakes in Cashmere. It breeds in June, builds a largish nest of dry sedge, woven round five or six reeds, of a deep cup form, which it places about 2 feet above the water. It lays four or five eggs, rather blunt ovals, equally blunt at both ends, blotched with olive and dusky grey on a dirty-white ground."

Mr. S.B. Doig, who found this bird breeding in the Eastern Narra in Sind, writes:--"On the 4th August, while my man was poling along in a canoe in a large swamp on the lookout for eggs, he passed a small bunch of reeds and in them spotted a nest with a bird on it. The nest contained three beautiful fresh eggs. A few days later I joined him, and on asking about these eggs he described the bird and said he had found several other nests of the same species, but all of them contained young ones nearly fledged. I made him show me some of these nests, all of which were situated in clumps of reed, in the middle of the swamp, and in these same reeds I found and shot the young ones which, though fledged, were not able to fly. These I sent with one of the eggs to Mr. Hume, who has identified them as belonging to this species. The nests were composed of frayed pieces of reed-grass and fine sedge, the latter being principally towards the inside, thus forming a kind of lining. The nests were loosely put together, were about 3 inches inner diameter, 1¼ inch deep, the outer diameter being 6 inches. They were situated about a foot over water-line in the tops of reeds growing in the water."

Colonel Legge says:--"This species breeds in Ceylon during June and July. Its nest was procured by me in the former month at the Tamara-Kulam, and was a very interesting structure, built into the fork of one of the tall seed-stalks of the rush growing there; the walls rested exteriorly against three of the branches of the fork, but were worked round some of the stems of the flower itself which sprung from the base of the fork. It was composed of various fine grasses, with a few rush-blades among them, and was lined with the fine stalks of the flower divested, by the bird I conclude, of the seed-matter growing on them. In form it was a tolerably deep cup, well shaped, measuring 2½ inches in internal diameter by 2 in depth. The single egg which it contained at the time of my finding it was a broad oval in shape, pale green, boldly blotched with blackish over spots of olive and olivaceous brown, mingled with linear markings of the same, under which there were small clouds and blotches of bluish grey. The black markings were longitudinal and thickest at the obtuse end. It measured 0·89 by 0·67 inch."

The eggs of this species, as might have been expected, greatly resemble those of A. arundinaceus. In shape they are moderately elongated ovals, in some cases almost absolutely perfect, but generally slightly compressed towards one end. The shell, though fine, is entirely devoid of gloss.

The ground-colour varies much, but the two commonest types are pale green or greenish white and a pale somewhat creamy stone-colour. Occasionally the ground-colour has a bluish tinge.

The markings vary even more than the ground-colour. In one type the ground is everywhere minutely, but not densely, stippled with minute specks, too minute for one to be able to say of what colour; over this are pretty thickly scattered fairly bold and well-marked spots and blotches of greyish black, inky purple, olive-brown, yellowish olive, and reddish-umber brown; here and there pale inky clouds underlay the more distinct markings. In other eggs the stippling is altogether wanting, and the markings are smaller and less well-defined. In some eggs one or more of the colours predominate greatly, and in some several are almost entirely wanting. In most eggs the markings are densest towards the large end, where they sometimes form more or less of a mottled, irregular, ill-defined cap.

In length the eggs vary from 0·8 to 0·97, and in breadth from 0·58 to 0·63; but the average of the only nine eggs that I measured was 0·89, nearly, by rather more than 0·61.

366. Acrocephalus dumetorum, Blyth. Blyth's Reed-Warbler.

Acrocephalus dumetorum, Bl., Jerd. B. Ind. ii, p. 155. Calamodyta dumetorum (Bl.), Hume, Rough Draft N. & E. no. 516.

Blyth's Reed-Warbler breeds, I believe, for the most part along the course of the streams of the lower Himalayan and sub-Himalayan ranges, and in suitable localities on and about these ranges; such at least is my present idea. They are with us in the plains up to quite the end of March, and are back again by the last day of August, and during May at any rate they may be heard and seen everywhere in the valleys south of the first snowy range.

Mr. Brooks remarks that "this species was excessively common on the Hindoostan side of the Pir-pinjal Range, but I have never seen it in Cashmere. I think it breeds in the low valleys by the river-sides, for it was in very vigorous song there at the end of May." This is my experience also, and probably while many may go north to Central Asia to breed, a good many remain in the localities indicated.
