Northern Portion of the Malay Peninsula . 
very fond of perching on the top branches of lofty dead trees 
on the edge of the jungle or on the banks of rivers, leaving 
their perches for a few moments to hawk after insects and 
always returning to the same place. They are specially 
attracted by termites, and large numbers of these species, as 
of other Swifts and Goatsuckers, appear when these insects 
are flighting, which is generally at dusk after heavy rain.

Harpactes orescius (Temm.); Grant, Cat* Birds Brit. Mus*

Pyrotrogon orescius Robinson, p. 176. 
Very numerous both in Trang and on the Langkawi 
Islands, and the only member of the family met with in 
either of these localities. In the central and southern 
portions of the Peninsula it is a very much rarer bird. 
CuCULIDiE. 
100. COCCYSTES COROMANDUS. 
Coccystes coromandus (Linn.) ; Shelley, Cat. Birds Brit. 
Mus. xix. p. 214 (1891). 
Very common in Trang in the open country, and also in 
the Langkawi group ; it was met with, together with several 
other migratory Cuckoos, on the Aroa Islands in the middle 
of the Straits of Malacca, in November and December 1906. 
In the south of the Peninsula, at any rate in the more 
inland districts, it is very much rarer. 
We believe this to be largely a migratory species, occurring 
in numbers only in the winter months, though Davison 
obtained specimens in Malacca in July. 
101. SURNICULUS LUGCJBRIS. 
Sumiculus lugubris (Horsf.); Shelley, tom. cit. p. 176; 
Robinson, p. 176. 
The Drongo-Cuckoo is very common throughout the 
Peninsula at all times of the year.
