SIPHIA SUPERCILIARIS AESTIGMA (G. R. Gray) 



Eastern White-browed Flycatcher 



Muscicapa aestigma G. R. Gray, Catalogue of . . . Mammalia and birds of Nepal 

 and Thibet . . . British Museum, 1846, pp. 90, 155 (Nepal).

I found this charming little flycatcher to be a rare winter visitor to 

 the hills of the Thanon Thong Chai range. The only records are : An 

 adult male shot on Doi Suthep at 4,200 feet, February 26, 1932 ; another 

 taken on the same mountain at 1,700 feet, December 5, 1936, and a third 

 observed at 1,500 feet, January 9, 1937; an adult male (one of several 

 seen) collected on Doi Chiang Dao at 5,000 feet, March 20, 1937. 



The two examples from lower elevations were in deciduous jungle, 

 those from the heights in pine-forest. The specimen from Doi Chiang 

 Dao, loosely accompanied by others of the same species, was probably 

 bound for the northern breeding ground. 



My birds had the irides dark brown ; the bill, feet, toes, and claws 

 black. ^-'1£il§p0| 



The adult male has the entire upperparts ultramarine, brighter on 

 the front and forecrown, the secondaries narrowly margined along 

 the outer web with bluish white ; a supercilium occasionally indicated 

 by a few scattered bluish-white feathers; the sides of the head, neck, 

 and breast deep ultramarine; the remaining underparts white, this 

 color extending from the upper abdomen to the chin as a broad central 

 streak. The adult female has the entire upperparts ashy gray, more 

 or less suffused with brown on the front, forecrown, and upper tail 

 coverts ; the sides of the head, neck, and breast ashy gray ; the remain- 

 ing underparts white, as in the male.
