(889) Seicercus burkii burkii.
The Black-browed Flycatcher-Warbler.
Sylvia burkii Burton, P. Z. S., 1835, p. 153 (Himalayas). Cryptolopha burkii. Blanf. & Oates, i, p. 424.
Vernacular names. Inshushia-gadeba (Kacha Naga).
Description. Differs from S. affinis in having a yellow ring all round the eye; the central coronal streaks and sides of the head are green, much the same in tint as the upper parts and in but few cases faintly tinged with grey; the lateral coronal bands are a browner black and are not carried so far down the nape; upper parts a lighter olive-green and lower parts more tinged with orange.
Colours of soft parts. Iris dark brown; upper mandible horny-brown to almost black, lower mandible yellow-horny; legs and feet pale horny-yellow.
Measurements. Total length about 110 to 115 mm.; wing 55 to 60 mm. (one 63 and two specimens 62 mm.); tail 45 to 46 mm.; tarsus about 18 mm.; culmen about 10 mm.
Distribution. Himalayas from extreme North-West and Kashmir to Manipur, and Hills South and East of the Brahmaputra.
Nidification. The Black-browed Flycatcher-Warbler breeds in Assam from early April to the end of May, making a nest very-similar to that of Seicercus affinis, but dispensing with the soft inner lining of vegetable-silk or cotton. It is nearly always placed on the ground and only exceptionally on dead trees and, even then, always quite close to the ground and carefully concealed. The eggs cannot be distinguished from those of the last bird but average a good deal larger. Forty eggs average 16.1 x 12.3 mm.: maxima 16.7 X 13.1 mm.; minima 15.9 x 11-8 mm.
In Assam it breeds from 4,500 to 7,000 feet, but in Sikkim Mr. Osmaston found it breeding in July at 6,500 feet, and Mr. H. Stevens thinks it breeds up to at least 9,000 feet.
Habits. Similar to those of the preceding species.
