In any other parts of the country it was never observed. 
The colour of the upper parts of the body is rather variable as seen by a series 
in the Royal Natural History Museum in Stockholm. In old birds the underparts of 
the body are very dark slaty black without traces of the white bars which are very con- 
spicuous in young birds. 
Immature specimens have the primaries dark rufous brown with orange brown 
shafts to the primaries and secondaries, and the back is olive brown and not greyish 
as stated by Extior. In old birds the primaries and the secondaries are dusky black 
with an olivaceous brown shade on the outer webs. The shafts of the primaries and 
secondaries are black. The white spots above and below the eye seems to be larger and 
more prominent in the Hat Sanuk specimen than in specimens from the southern parts 
of the Malay Peninsula.

The first time I observed this Swallow-Shrike was near Chieng Sen, where a large 
flock had settled down in a bamboo-clump on the bank of the Mekong river. From their 
resting place they now and then made aerial evolutions, though always returing to the 
same place again where the whole party was perching quite close to each other like 
some kind of weaver-birds. 
At the neighbourhood of Koh Lak they were also obtained, though apparently 
more rare here than up in the Northern parts of the country. Here they haunted open 
sandy plains, resting on the branches of dead trees or on telegraph wires. At the environs 
of Bangkok I never observed them, but from that locality they have been recorded. by 
WILLIAMSON and other authors.
