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."
