Dicrurus leucophaeus disturbans Stuart Baiter, Nov. Zool., xxv, p. 293 (1918) (Amherst). Dicrurus nigrescens. Blanf. & Oates, i, p. 315.
Vernacular names. Lon-mi-sue (Burmese).
Description. Whole plumage steel-grey,, a little paler on the rump and paling slightly from the breast to the under tail-coverts, the steel sheen also gradually fading away on these parts ; lores and a line over the forehead dull black; wing-quills blackish brown; rectrices brownish at the tip. In abraded plumage obsolete dark centres to the feathers of the head and wing-coverts show up fairly plainly.
Colours of soft parts. Iris red to deep crimson; bill, legs and feet black.
Measurements. Total length about 250 to 260 mm.; wing 123 to 146 mm., average 127 mm.; tail 122 to 155 mm., average 131 mm.; culmen 21 to 22 mm.; tarsus about 18.5 to 19.5 mm.
Distribution. Malay Peninsula, except in the extreme Peninsular Burma and Siam as far North as Bangkok.
Nidification. Mr. Hopwood found this King-Crow breeding during April near Tavoy in Tenasserim, and Mr. W. A. T. Kellow sent me birds, nests and eggs procured in May near Simpang. Nests and eggs are indistinguishable from those of the well-known form D. l. longicaudatus, which are fully described later on. Fifteen eggs average 24.1 x 18.2 mm.: extremes, maxima 26.5 x 18.3 and 24.5 x 18.6 mm.; minima 21.5 X 18.1 and 24.0 x 18.0 mm.
Habits those of the species. This is perhaps more of a forest-bird than some of the geographical races of the Grey Drongo, and haunts thin deciduous forest and light scrub as well as well-wooded open lands. It is found alike on plains and up to 3,000 or 4,000 feet in the Burmese Hills.
