Thick-billed Warbler

This morning's offerings from Suan Rot Fai included a beady-eyed Thick-billed Warbler and a couple of Ashy Drongos - the first of both species this autumn.  Other migrants included four Pale-legged Leaf Warblers, two Eastern Crowned Warblers,  one Arctic Warbler,  two Black-capped Kingfishers and about five each of Taiga and Asian Brown Flycatcher.

Regarding Pale-legged Leaf Warbler, in recent years it has been split from Sakhalin Leaf Warbler.  The suspicion exists that Sakhalin LW may occur in Thailand, but the only reliable way to separate the two  species seems to be on song (not much good on migration!).  There is an interesting discussion here on the subject.
