"One nest, which I took on the 6th May, was a round ball with a lateral entrance; it was placed in a thick barberry-bush growing at the side of a deep and sheltered ditch; it was composed of coarse dry grasses externally and lined with finer grass. Eggs three and pearl-white, with minute scattered specks of rufous, chiefly at the larger end. Diameter 0·62 by 0·5."
The late Mr. A. Anderson wrote the following note:—"On the fifth day after leaving Naini Tal—ever mindful of my friend Mr. Brooks's parting advice to me (in reference to the part of the country which required to be investigated), 'avoid the lower hills as the plague'—I reached Takula, which is the first march beyond Almora on the road to the Pindari glacier, late on the evening of the 10th of May. It rained heavily all that night, so that I was obliged to halt the next day, my tents being far too wet to be struck, and the distance to the next halting-place necessitating a start the first thing in the morning.
"Takula is at an elevation between 5000 and 6000 feet; it is beautifully wooded, with a small mountain-stream flowing right under the camping-ground, and the climate is delightful. All things considered, I was not sorry at having an opportunity of exploring such productive-looking ground; and before it was fairly daylight the next morning operations were commenced in right earnest. To each of my collectors I apportioned off a well-wooded mountain-slope, reserving for my own hunting-ground (as I had not yet got my hill-legs) the water-courses and ravines in the immediate vicinity of my camp.
"Not more than 20 yards from where my tent stood, there is a deep ravine clothed on both banks with a dense jungle of the larger kind of nettle (Girardinia heterophylla: such nettles too!), the hilldock (Rumea nepalensis), and wild-rose trees. Wending my way through this dark, damp, and muggy nullah to the best of my ability, I came upon the nest of this interesting little bird; it was placed in the centre of a rose-bush, at an elevation of some two feet above the bank and about four feet from where I stood, but yet in a most tantalizing situation, inasmuch as it was necessary to remove several thorny branches before an examination of the nest was possible.
"The act of cutting away the branches alarmed my sombre little friend (I knew that the nest was tenanted, as the bill and head were distinctly visible through the lateral entrance), and out she darted with such a 'whir' that anything like satisfactory identification for a bird of this sort was utterly hopeless. The nest contained four beautiful little eggs, so that to bag the parent bird was a matter of the first importance; all my attempts, however, first to capture her on the nest and next to shoot her as she flew off, were equally futile, her movements being as rapid and erratic as forked lightning. And here let me give a word of advice to my brother ornithologists: Never attempt to shoot a wary little bird in the act of leaving its nest, as you only run the risk, and mortification I may add, of wounding perhaps an unknown bird, in which case she will never again return to her nest; but lie in ambush for her with, outlying scants, and make certain of her as she is returning to her nest. She will first alight on a neighbouring tree, then on one closer, coming nearer and nearer each time; finally, she will perch on the very tree or bush in which the nest is built, and while taking a look round to see that all is well before making a final ascent, you have yourself to blame if you fail to bag her. All this sounds very cruel; but if a bird must be shot for scientific purposes, it is surely preferable to kill it outright than to let it die a lingering death. Thus it was that I eventually succeeded, even at the expense of being devoured alive by midges and mosquitoes; but then had I not the satisfaction of knowing that to become the happy possessor of authentic eggs of Acrocephalus dumetorum was in itself sufficient to repay me for my hill excursion!
"I cannot, however, pretend to lay claim to originality in the discovery of the breeding-habits of this bird, for Hutton's description of the nest and eggs taken by him so fully accords with my own experience, that it is but fair to conclude he was correct in his identification. I would add, however, with reference to his remarks, that the nest above alluded to was more elliptical than spherical, being about the size and shape of an Ostrich's egg, that it was constructed throughout of the largest and coarsest blades of various kinds of dry grass, the egg-cavity being lined with grass-bents of a finer quality, and that it was domed over, having a lateral entrance about the middle of the nest. The whole structure was so loosely put together as to fall to pieces immediately it was removed.
"The eggs, four in number, are pure while, beautifully glossed, and well covered with rufous or reddish-brown specks, most numerous at the obtuse end. Owing to its similarity to a number of eggs, particularly to those of the Titmouse group, it is just one of those that I would never feel comfortable in accepting on trust.
"It was a remarkable coincidence that the very day I took this nest my post brought me part iv. of the P.Z.S. for 1874, containing Mr. Dresser's interesting paper on the nidification of the Hypolais and Acrocephalus groups; and if I understand him rightly, he is certainly correct in his surmise as to the eggs of Acrocephalus dumetorum approaching those of the Hypolais group.
"My good luck, as regards Blyth's Reed-Warbler, did not end here, for on the following day, at Bagesur, at an elevation of only 3000 feet, I again encountered a pair of these birds, finding their nest on the banks of the Surjoo. The position, shape, and architecture of this nest were identical with the one I have above described, but the eggs unfortunately had not been laid. The little birds, on this occasion, were quite fearless, hopping from stem to stem of the dense undergrowth which throughout the Bagesur valley fringes both banks of the river, every now and again making a temporary halt for the purpose of picking insects off the leaves, with an occasional 'tchick,' which Hutton resembles to the 'sound emitted by a flint and steel,' but all the time enticing me away from the site of their dwelling-place. In this way they led me a wild-goose chase several times up and down the river-bank before I was able to discover the whereabouts of their nest."
Captain Hutton sent me three eggs of this species. The eggs are otherwise unknown to me, and I describe them only on Captain Hutton's authority. The eggs are rather broad ovals, very smooth and compact in texture, but with little or no gloss. They are pure white, very thinly speckled with reddish and yellowish brown, the markings being most numerous towards the large end, and even there somewhat sparse and very minute. They measure respectively 0·65 by 0·52, 0·65 by 0·51, and 0·62 by 0·51.
