This small flycatcher has been found only on Doi Ang Ka (5,500 feet 

 to the summit) , on Doi Suthep (once, at 4,600 feet) , and on Doi Chiang 

 Dao (5,500 feet). Although seldom seen, it is probably a permanent 

 resident on many of the higher mountains of the more western 

 provinces. 



De Schauensee has noted (1929) that he shot a specimen out of a tall 

 tree, but all seen by me were perched within 2 or 3 feet of the ground 

 along narrow tracks through dense, moist evergreen forest; it is a 

 quiet little bird, and this fact, in conjunction with its choice of habitat, 

 may account for the paucity of records in our area. 



My specimens had the irides dark brown ; the bill black ; the tarsi 

 horny flesh ; the toes horn brown ; the claws horny. 



The adult male has a white frontal band (usually broken just at the 

 center) continued over either eye as a short supercilium; the entire 

 upperparts slaty blue; the remiges blackish brown, narrowly edged 

 along the outer web with dull rufous ; the rectrices slaty blue, all except 

 the two central pairs with the extreme base wholly or largely white; 

 the lores, chin, and sides of the throat blackish, changing to slaty blue 

 on the sides of the head, neck, and breast and along the flanks; the 

 center of the throat and breast orange-rufous, this color changing 

 gradually to olivaceous-brown on the sides of the abdomen and to 

 white on the center of the abdomen and the under tail coverts. The 

 adult female has the forehead and supraloral line rufous-buff; the 

 remaining upperparts olivaceous-brown, the remiges and rectrices 

 narrowly edged with rufescent along the outer web; the underparts 

 rufous-buff, more brownish along the flanks, albescent on the center 

 of the throat and abdomen.

Langka). 



The white-throated flycatcher has been found in our provinces only 

 on Doi Pha Horn Pok, Doi Langka, Doi Suthep (twice), Doi Ang Ka, 

 and Phu Kha; it is probably a rare permanent resident wherever 

 dense, humid evergreen grows at elevations in excess of 4,500 feet.
