"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 grass-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 shells 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 0·6 to 0·7, and in breadth from 0·45 to 0·5; but the average of fifty eggs measured is 0·64 by 0·46. 375. Orthotomus atrigularis, Temm. _The Black-necked Tailor-bird_.
