Generally it was seen perching on a lofty branch at the top of a high tree, now and then 
darting after a passing insect. 
Rather common as far south as Koh Lak in the Siamese Malaya.

As far as I can see the Ashy Drongos inhabiting Siam ought to be referred to the 
race described by LorD WaLpDEN under the above-mentioned name. 
As compared with a series of B. c. cineracea Horsf. from Java, the Siamese birds 
are at a glance distinguished by their paler underparts and their larger bills. The upper 
parts of the body are also slightly paler, especially the crown. The Siamese specimens 
have their lores blackish which is also a point of characteristic to B. c. mouhoti. 
From B. leucogenys Waup. they differ by having the under wing-coverts very dark 
and without the white edges, which are very conspicuous in that form. Its nearest ally 
is B. c. nigrescens OaTES. but it is separated from that species by its much paler colouring.

Several distinct races have been described of this bird. The form inhabiting North- 
ern Siam cannot be the typical Dissemurus paradiseus Linn. because of its enormous 
crest and its long hair-like frontal plumes. In one of my specimens the longest crest- 
feathers are 45 mm. The form described by Linnaus has a very small crest and the size 
of the bird is rather small. This race inhabits Java, the Malay Peninsula and probably
