Abrornis superciliaris salwinensis Stuart Baker, Bull. B. O. O xliv, p. 62 (1924) (Salween).
Vernacular names. Daotisha mini (Cachari).
Description. Differs from A. s. superciliaris in having the whole crown brownish grey and the upper parts a trifle darker, more green, less yellow.
Colours of soft parts as in the preceding bird.
Measurements. Wing 44 to 51 mm.; tail 39 to 42 mm.; culmen about 11 mm.
Distribution. Hills of Assam, South of the Brahmaputra, all Burma to Yunnan, and south to the northern portions of Tenasserim; Northern Siam.
Nidification. This race of Yellow-bellied Flycatcher breeds from about 1,000 feet, or lower at Margherita, up to some 5,500 feet during April, May and early June. The nest is nearly always placed in a dead bamboo, very rarely in a hole in a small branch of a tree; it is made of any dry material such as bamboo-leaves, bamboo-fibre, other leaves and roots, over which is always placed a pad of felted green moss, from one to six inches deep. The eggs vary from three to five, and are of two types, one white, boldly spotted everywhere with reddish brown, the other pale pink, the whole surface covered with minute freckles of darker brick-pink, so closely that they appear to be unicoloured glossy pink eggs. Intermediate types occur only seldom but in the pink eggs a ring of darker tint at the larger end is not rare. Thirty eggs average 13.2 x 11.5 mm.: maxima 16.3 X 11.5 and 16.0 x 12.2 mm.; minima 14.5 x 11.5 and 15.0 x 11.1 mm.
Habits. This is a very common little bird in the Assam Hills, wandering well out into the plains in Winter and being found up to 6,000 feet in Summer. It is a fascinating little bird to watch, very confiding and never still except when uttering its pleasing little song. It catches its insect-food almost entirely on the wing, looking much like a butterfly as it flutters in the air.
