(695) Hypothymis azurea tytleri (Beavan).
THE ANDAMAN BLACK-NAPED FLYCATCHER.
Hypothymis azurea tytleri, Fauna B. I., Birds, 2nd ed. vol. ii, p. 273.
As its name infers, this Flycatcher is confined to the Andamans, where it is found to be, according to Osmaston (Journ. Bomb. Nat. Hist. Soc. vol. xvii, p. 159, 1906), “common both in the forest and in and about Port Blair. It is wonderfully active, as well as fearless.” The first nest ever taken is well described by Hume (‘Nests and Eggs,’ p. 30):—“A nest was found at Aberdeen, South Andaman, on the 23rd April, 1873 ; it was fastened to the branch of a small tree that overhung the path. In shape it was an inverted cone, 3 inches in depth exteriorly and 2.1/2 inches in diameter ; the egg-cavity, which is nearly hemispherical, is 2 inches in diameter and 1.1 in depth. The nest is very compactly woven of soft vegetable fibre, with which also it is firmly bound against the slender stem to which it is attached. Towards the exterior a good deal of green moss, a number of satiny white cocoons, and a little bright ferru¬ginous fern-root have been incorporated in the nest, and the whole carefully coated, though not thickly so, with gossamer threads and spiders’ webs, and the cavity of the nest neatly lined with black hair-like moss-roots.”
Since then Osmaston, Wickham and Anderson found many nests and, roughly, the description of the nest given by Hume would suit any one of these, except that moss was very seldom used as a decoration for the outside, though the white cocoons and spiders’ egg-bags are always in evidence. The shape may be either a deep little cup or an inverted hollow cone, while the principal material is described as “vegetable fibre” or, more rarely, soft grass.
Osmaston found them placed at heights varying from 5 to 10 feet from the ground, nearly always fixed in an upright fork of a branch of some small sapling.
The breeding season is from the end of April to the end of June. Wickham took his earliest nest on the 22nd April, while Osmaston took his latest on the 21st June.
The eggs, which number three, less often two, in a clutch, are just like those of the Indian bird but, when looked at as a series, appear to be less deep in ground-colour, more often white, or nearly so, and not so frequently warm salmon-pink.
Fifty-four eggs average 18.3 x 13.9 mm. : maxima 19.7 x 14.5 and 19.2 x 14.8 mm. ; minima 17.0 x 13.9 and 18.2 x 13.2 mm.
The maxima and minima are both represented in the Osmaston collection, which has passed into my possession since the ‘ Fauna was published.
