The white-throated fantail is a very common or even abundant 

 permanent resident in the heavy evergreen of the provinces west of 

 (and including) the Khun Tan chain; on such mountains as Doi 

 Suthep and Doi Ang Ka it is unknown below 3,200 and 4,300 feet 

 respectively, but where the evergreen reaches the bases of the hills, as in 

 western Chiang Eai, it occurs almost at the level of the plains. 



In suitable forest this is one of the most conspicuous and unmistak- 

 able birds ; a pair may be found with almost any mixed band of small 

 babblers, and it is sure to be seen at the edge of old clearings and along 

 the tracks and stream courses. Like its congener of the plains, it is 

 in constant motion, dashing from branch to branch, swooping and 

 diving through the air with snapping bill, and forever spreading and 

 folding the flabelliform tail. On Doi Suthep and other peaks of the 

 Thanon Thong Chai range, only CuUcicapa, of all the family, is 

 equally numerous. 



Smith collected a full-plumaged juvenile on Doi Langka, May 2, and 

 Gyldenstolpe (1916) took juveniles on Doi Khun Tan, May 24 and 30. 

 A specimen from Doi Suthep, July 15, is in postnuptial molt. 



The adult has a short, narrow supercilium white ; the lores, eye ring, 

 and forehead black, this color changing to slaty black on the crown 

 and ear coverts and to deep slaty gray on the mantle; the remiges 

 blackish brown ; the rectrices brownish black, the central pair wholly 

 of this color, the next pair narrowly tipped with ashy white, and the 

 remaining pairs broadly tipped with the same ; the feathers of the chin 

 deep slaty gray, those of the throat similar but more or less broadly 

 fringed with white; the remaining underparts slaty gray (paler than 

 the mantle), the feathers at the center of the abdomen often tipped 

 or fringed with ashy ("<?gfea") ; the under wing coverts and axillaries 

 mixed slaty gray and ashy white. The juvenile differs from the adult 

 only in having the upper wing coverts, the inner secondaries, and the 

 feathers of mantle and abdomen fringed with ferruginous.
