(772) Dicrurus leucophaeus nigrescens.
The Burmese Grey Drongo.
Dicrurus nigrescens Oates, Hume's Nests and Eggs, 2nd ed. i, p. 208 (1889) (Rangoon) ; Blanf. & Oates, i, p. 315.
Vernacular names. Lon-mi-sue (Burmese).
Description. Generally speaking, a darker bird than D. I. disturbans and decidedly bigger.
Colours of soft parts. The same in all the races.
Measurements. Wing (123) 128 to 143 mm., average 132 ; tail 124 to 154 mm., average 138 mm.
Distribution. All Central Burma and Siam from about the latitude of Bangkok, North to the South Chin and Kachin Hills; South Shan States and South Yunnan.
Nidification. There is nothing on record about the nidification of this Drongo, although common enough in many parts of Burma. A clutch of eggs taken by Mr. J. C. Hopwood are like the pink type of eggs of B. l. longicaudatus, and were taken at Maymyio in May. They measure about 24.5 X 18.3 mm.
Habits the same as those of other races. This is a bird of father higher elevations during the breeding-season, April to June, but spreads over a great part of Burma during the cold weather. Much still remains to be learnt about its local movements and migrations.
