All these birds are fully adult, those from the Butang Ids. 

 being in breeding condition. Immature birds shot on Koh 

 Samui, Bandon Bight in May and Pulau Ketam, coast of 

 Selangor, in July, have the outer webs of the inner secondaries 

 rufous brown and the wing coverts tipped and edged with the 

 same colour. 



Very common on most small islands near the Malay 

 Peninsula where there is mangrove forest and also along the 

 coast ot the mainland in similar situations, but so far as my 

 experience goes never found in dry forest. 



There has been much discussion as to the systematic 

 position of this bird. It is certainly not a typical Pachycephaltt 

 but would appear to be best placed in a genus of its own. 

 near to Niltava and Rhinomyias. If only on zoogeographical 

 grounds, it must be removed from Pathycephala.
