914. Homochlamys pallidipes osmastoni

(914) Homochlamys pallidipes osmastoni (Hartert).
THE ANDAMAN WHITE-FLANKED BUSH-WARBLER.
Horornis pallidipes osmastoni, Fauna B. I., Birds, 2nd ed. vol. ii, p. 509.
Homochlamys pallidipes osmastoni, ibid. vol. viii, p. 645.
So far as is known at present this Bush-Warbler is confined to the Andamans.
The only person who has taken its nest and eggs is its discoverer, B. B. Osmaston, who thus records the nidification (Journ. Bomb. Nat. Hist. Soc. vol. xxxv, p. 892, 1932) :—“These birds are common in dense undergrowth of high or secondary forest and are never met with in the open. They are adept skulkers and, though often heard, are seldom seen.
* The type of this bird is now in America, so that I cannot examine it, but the eggs are so unlike those of any other Homochlamys that I feel sure it will prove not only to be a separate species but, possibly, a separate genus.
“On May 19th, 1907, while pushing through dense jungle near the top of Mt. Harriet (1,000'), I came on an Horornis calling. I began to search for a possible nest, when the parent bird began to give its alarm call chick-chick. This spurred me on to further endeavours, and shortly I was rewarded by finding the nest within a foot of the ground. It was a deep cup-shaped structure—not domed, but completely sheltered by a leaf of a ginger. The nest was supported among the stems and leaf-stalks of the ginger-like plant and was very difficult to locate, as nearly every ginger plant had a similar accumulation of dead leaves near the base, which resembled the nest.
“While examining the nest the parent bird came within 2 feet of me although, as a rule, it is almost impossible to get a sight of one in the jungle.
“The nest was composed of dry bamboo leaves, very loosely put together, and was fined with fine flowering grass-heads.
"The eggs, four in number, were quite fresh. They are moderately broad ovals, very glossy and of a bright chestnut colour, mottled all over, especially at the large end, with a deeper shade of chestnut.
“A second nest was brought to me on the 10th July, containing four fresh eggs of a similar colour. The second nest was lined with dark rhizomorph instead of grass.”
The average of the eight eggs is 17.0 x 13.6 mm. : maxima 17.8 x 14.0 mm. ; minima 16.2 x 13.4 mm.
The eggs are not a bit like those of H. p. pallidipes. The texture is intensely glossy, like Tinamus or Hydrophasianus eggs, and in colour they are brilliant brick-red or chestnut, the mottling only showing under a glass. Instead of being very brittle and fragile, like all other Homochlamys eggs, they are exceptionally stout and strong.
