The rare white-headed ashy bulbul has been found in Thailand on 

 the five peaks named above, at elevations between 3,800 and 5,500 feet. 



This is a bird of lightly wooded country at high altitudes : On Doi 

 Ang Ka, I noted it in the semicleared valley below Pha Mon ; on Doi 

 Chiang Dao, at the poppy gardens of the Musoe and in the thin trees 

 o-rowing from the great precipices of the southern wall (above abysses 

 so deep that specimens could not be taken) ; on Doi Suthep, in the park- 

 like areas of widely spaced pines. Only on Doi Chiang Dao, where 

 there is plenty of open forest at suitable elevations, it is comparatively 

 common. 



On Doi Chiang Dao, in March, 1937, I observed it in loose flocks 

 of a score or more, but on Doi Suthep it was always seen singly or 

 in pairs at any season, possibly because of the small number inhabiting 

 the latter mountain. In flocks it is a clamorous species, in pairs silent 

 and inconspicuous. Stomachs examined by me contained only insects. 



On Doi Suthep, 5,500 feet, I took a female with enlarged gonads, 

 April 2, 1931, and, on the same hill, watched a pair at 3,800 feet, May 

 13 and 14, 1935, which almost certainly had nestling young in the 

 vicinity. Smith took a juvenile on Doi Langka, April 26, 1931, and 

 another in postjuvenal molt on Doi Hua Mot, August 22, 1934. A 

 bird from Doi Ang Ka, 4,500 feet, September 8, 1935, is in postnuptial 

 molt. 



Adult females had the irides light yellow or brownish yellow ; the 

 eyelids edged bright vermilion-red or coral red; the naked orbital 

 skin gray-brown or slaty brown ; the bill coral red, yellowish or horny 

 at the extreme tip ; the interior of the mouth coral red ; the feet and 

 toes coral red ; the claws horny brown or brown with an orange tinge. 



The adult of either sex has the entire head and neck pure white; 

 the rest of the plumage ashy gray (the remiges and rectrices darker, 

 almost slaty), except for the dull chestnut-rufous under tail coverts. 

 The immaculate white of the head is a character of maturity ; see Riley 

 (loc. cit.) for descriptions of the juvenile specimens collected by Smith.
