Mr. W. J. F. Williamson has examples from Chumporn and 

 Bangtaphan. 



It is curious that this bird should, so far as is known to 

 date, not occur in Tenasserim, while it is found on the other side of 

 the range at the above locality and also in Eastern Siam and French 

 Indo-China. The species is, at all events, partially migratory, but 

 less so than M. javanicus, though in the more southern parts of its 

 range it may be met with throughout the year.
