with buff; the lores, supercilium, and sides of the head and neck

The beautiful red-tailed garrulax has been found only on Doi 

 Langka and Doi Pho Horn Pok, but, on these two mountains at least, 

 it is a common bird at the higher elevations. At the former locality 

 Smith saw it in large flocks and collected no less than 15 specimens 

 between April 22 and 27, 1931 ; at the latter, de Schauensee's men took 

 a fine series during an equally short period. 



Nothing has been recorded of its habits in Thailand, and I myself 

 never had the good fortune to see this species in life. One of Smith's 

 examples from Doi Langka, November 9, is undergoing postnuptial 

 molt. 



The adult has the forehead, crown, and nape orange-rufous; the 

 mantle ashy olive, becoming olivaceous-brown on the rump and upper 

 tail coverts, the feathers of the back narrowly edged with dull blackish 

 brown to give a scaled appearance; the remiges with the outer web 

 largely bright, shining red, the inner web black (except the innermost 

 secondaries, which have the inner web largely white) ; the rectrices 

 red above, blackish beneath ; the lores and a narrow supercilium black, 

 the latter becoming white near the posterior end; the ear coverts 

 silvery gray ; the chin and throat blackish, changing on the remaining 

 underparts to dark ashy gray, posteriorly more or less suffused with 

 olivaceous-brown.
