(Doi Nang Kaeo). 



The blue-breasted flycatcher is local and uncommon in the northern 

 provinces, from most places known by a single specimen and not yet 

 recorded at all from Mae Hong Son and Chiang Rai. In addition 

 to localities named above, I have it from Ban Samoeng, Ban Huai 

 Chang Tai, Doi San Huai Wai, Ban Huai Ki, and Ban Nam Puat (in 

 the French Enclave). 



This species occurs in uninhabited and broken country at the foot 

 of the mountains, haunting light evergreen, mixed-deciduous forest, 

 and bamboo, rarely reaching such high elevations as 2,800 (Doi Nang 

 Kaeo) or 3,000 feet (Doi Khun Tan). 



A juvenile (sexed as a male but probably a female) was taken at 

 Phu Het, in the southern part of Nan Province, June 9, 1936. From 

 equaeval examples of Cyornis t. sumatrensis, collected at the same 

 time and place, it is clearly separable only by its brown rectrices 

 without the least trace of blue. 



Gyldenstolpe notes (1916) that his specimens had the irides dark 

 brown ; the bill black ; the feet and toes pale brown. 



The adult male has the forehead, supercilium, and shoulder patch 

 shining blue; the lores black; the remaining upperparts deep blue; 

 the chin, throat, and breast indigo-blue, gradually changing to smoky 

 along the flanks and to white on the abdomen, under tail coverts and 

 under wing coverts (this last color often encroaching boldly on the 

 center of the breast and throat) ; the thighs slaty blue. The adult 

 female has the upperparts olivaceous-brown, grayer on the crown 

 and nape, rufescent on the upper tail coverts and tail ; the lores and 

 orbital region grayish white or rusty white ; the underparts dull orange, 

 strongly infuscated on the sides of the throat and breast, changing to 

 white on the abdomen and under tail coverts.
