For many years this rare woodpecker was known from Thailand 

 only by Williamson's old record. In 1936 I sent my men to Ban Mae 

 Mo especially to make a search for it and on the last day of a week's 

 stay, September 2, an adult male was seen and collected. Curiously 

 enough, just eight days later, I myself shot a second adult male a few 

 miles south of Ban Mae Ten, a village in the upper Mae Yom basin. 

 However, unknown to me, Smith had obtained a specimen (adult 

 male) at Huai Salop, January 3, 1933. 



It is a bird of low elevations, inhabiting parklike pa daeng, where 

 the trees are widely spaced and fairly tall. I found it a shy, solitary 

 form, most easily discoverable by its call — the notes of a Dryobates 

 but the voice of a Dinopiwn. 



My two September specimens are in molt. 



Smith records that his example had the maxilla black ; the mandible 

 horn ; the feet and toes green. 



The adult male has the forehead, lores, chin, and sides of the head 

 to the eye gray ; the crown and nape shining crimson ; the remaining 

 upperparts boldly barred black and white, except for the shoulders, 

 upper tail coverts, and central rectrices, which are uniform black; 

 the region of the vent and the under tail coverts rose-red or crimson ; 

 the remaining underparts unmarked rufous. The adult female differs 

 only in having the crown and nape black, thickly spotted with white. 

 Juveniles of either sex have the crown like that ©f the adult female, 

 except that the anterior portion is spotted with crimson instead of 

 white; the underparts (except for the pink under tail coverts) rufous- 

 gray or pale rufous, everywhere barred with blackish. 



Thai examples agree well with a series from the eastern Himalayas. 



Ticehurst and Whistler have set aside Hartert's restriction of the 

 type locality for the nominate race and rechristened the population of 

 the eastern Himalayas sikkimensis (Ibis, 1924, p. 473). Since some 

 forms in the original collection clearly did not come from the western 

 Himalayas; since Gould's plate, founded upon Vigors's type, does 

 indeed seem to represent an eastern bird; and since Hartert, the 

 first reviser, designated a not improbable type locality, to refuse to 

 accept his conclusions seems highhanded and unwarrantable.
