(901) Abrornis schisticeps flavimentalis.
The Chin Hills Black-faced Flycatcher-Warbler.
Abrornis schisticeps flavimentalis Stuart Baker, Bull. B. O. C, xliv, p. 63 (1924) (Mt. Victoria).
Vernacular names. None recorded.
Description. Similar to A. s. schisticeps, but with the yellow much paler and confined to the chin and throat, merely showing as a trace on the breast and flanks.
Colours of soft parts as in A. s. schisticeps.
Measurements. Wing 46 to 48 mm.; tail 40 to 41 mm.; tarsus about 17 mm.; culmen 7 to 8 mm.
Distribution. Hills of Assam, South of the Brahmaputra, Manipur and Chin Hills.
Nidification. The only nest I have seen of this Warbler was placed in a small bamboo, one of several which had been cut down to repair a bridge and then left nearly upright against the clump. The nest was made of roots and fibres resting on one of the nodes and above this was a well-matted pad of moss, upon which lay four eggs. The entrance was a small cut made in the bamboo about a foot above the nest, just big enough to permit the bird to enter. The eggs were exactly like those taken by Gammie of A. s. schisticeps and varied in size between 15.4 x 11.3 and 15.1 x 11.1 mm. They were taken on the 1st of May at about 3,000 feet elevation.
Habits. This Fly catcher-Warbler, though by no means shy, keeps much to open glades and river-sides in deep forest, or to bamboo-jungle with plentiful undergrowth. It is also a much more silent bird than most species of this genus. It thus escapes observation more than they do and probably appears to be more rare than it really is.
