“Tris dark or hazel; upper mandible black, lower 
brownish, feet brownish.” 
This Sun-bird was fairly common in open country in the 
Korinchi Valley and on the coast, feeding on the inflorescence 
of Coconut Palms and on the blossoms of Hibiscus and other 
conspicuous flowering shrubs. It was never found in old 
jungle. 
These specimens may be regarded practically as typical, 
Raffle’s original types having been obtained at Bencoolen, only 
slightly to the southward.
