I have found this species usually in humid evergreen jungle but 

 occasionally in the pines adjacent to such forest. 



Specimens with the gonads greatly enlarged were taken March 12 

 and May 13. De Schauensee has recorded (1934) an example in post- 

 juvenal molt, July 21; Smith collected birds in postnuptial molt, 

 August 28 and September 2. 



A breeding male had the irides brown ; the bill black ; the feet and 

 toes brown ; the claws horny brown. 



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

 shining blue ; the remaining upperparts a beautiful soft blue ; the chin, 

 throat, and breast a similar but paler blue, changing to bluish ashy on 

 the remaining underparts (albescent on the center of the abdomen) ; 

 the under tail coverts bluish ashy (often washed with buff) , broadly 

 tipped with bluish white ; the under wing coverts and axillaries buffy 

 white. The adult female has the upperparts olivaceous-brown, suf- 

 fused with rufescent on the mantle and changing to rufous along the 

 outer webs of the remiges and on the upper tail coverts ; the rectrices 

 rufous-brown; a conspicuous buffy- white eye ring; the underparts 

 sooty gray, more or less strongly suffused with buff, especially at the 

 sides of the throat, along the flanks, and on the under tail coverts 

 (albescent on the chin, center of the throat, and center of the abdo- 

 men) ; the under wing coverts and axillaries buffy white.

The verditer-blue flycatcher is a fairly common resident of the more 

 open evergreen on the mountains of the Thanon Thong Chai and 

 Khun Tan ranges and on Phu Kha, at elevations between 3,500 

 (rarely 2,700) and 5,500 feet. During the cold weather it also occurs
