The present race is a common winter visitor to northern Thailand, 

 where it has been noted from September 12 (1936) at Ban Tha Fa to 

 April 13 (1936) on Phu Kha. It seems to be restricted to the more 

 open evergreen forest but in that type of growth ranges from the plains 

 (Chiang Saen) to an elevation of 6,400 feet (Doi Pha Horn Pok). 



This form travels through the lower trees in company with such 

 birds as Cullcicapa, Hypothymis, Erpornis, and the various species of 

 Phylloscopus. Like its near relatives, it is more or less constantly in 

 motion, whether foraging among the leaves or darting through the 

 air in pursuit of flies and other small game. 



A male had the irides dark brown ; the maxilla dark horny brown ; 

 the mandible horny yellow ; the feet and toes horny yellow ; the claws 

 yellow. 



The adult has a broad coronal streak ashy gray, more or less strongly 

 suffused with olive-green, and bordered at each side by a broad band 

 of dull black; the lores, ocular region, ear coverts, and entire upper- 

 parts olive-green; a conspicuous and unbroken eye ring of yellow 

 feathers; the two outermost pairs of rectrices with the inner web 

 white ; the entire underparts yellow, more olivaceous along the sides 

 of the body.

This flycatcher warbler winters in small numbers in the provinces of 

 Chiang Mai and Mae Hong Son, whence it is now known by nine speci- 

 mens collected between November 25 (1931) and March 23 (1936,1937). 



Six of these examples were shot in lowland bamboo brakes, which
