THE BIRDS OF NORTHERN THAILAND 247 



Doi Suthep I sometimes saw it in the open hill-forest between 3,300 

 and 4,600 feet, and on Doi Ang Ka it occurred in pines at 4,000 feet. 



This bird, which may readily be distinguished from others of the 

 genus by its small size, seems not to differ from them in notes and 

 habits. 



A well-grown juvenile was taken at Phu Het, June 13. Adults 

 collected between August 2 and 28 are in molt. 



Gyldenstolpe notes that his specimens had the irides gray, yellowish 

 white, or brown; the bill bluish black; the feet and toes yellowish 

 green. 



The adult male has the crown ashy gray ; the sides of the crown from 

 above the eye, the nape, and the uppermost back black; at each side 

 of the occiput a narrow streak of scarlet; the remaining upperparts 

 black, barred and spotted with white; the sides of the neck from the 

 eye white, bordered below by a broad streak, anteriorly brown, poste- 

 riorly black; the remaining underparts gray, more or less suffused 

 with fulvous and everywhere streaked with blackish. The adult fe- 

 male differs only in lacking scarlet on the head. 



Ticehurst has shown (Journ. Bombay Nat. Hist. Soc, 1940, p. 592) 

 that my restoration of Hargitt's name pumilus for a supposedly 

 browner Indo-Chinese population cannot stand. In the meantime 

 de Schauensee has named the bird of eastern Thailand delacouri 

 (Proc. Acad. Nat. Sci. Philadelphia, 1938, pp. 109-111). When only 

 fresh-plumaged specimens (September to December) are compared, 

 the alleged differences between canicapillus and delacouri are not very 

 obvious, but in series they seem to be indeed separable. 



It is possible that the birds of Nan Province should be called dela- 

 couri, but my material (females taken from April to June) does not 

 permit me to decide this point.

The heart-spotted woodpecker is sparsely distributed across the low- 

 lands of the more eastern provinces ; its known range in our area does 

 not extend beyond Tha Chomphu and Ban Mae Dok Daeng Nai, 

 localities at the western foot of the Khun Tan chain. 



It has been found in heavy evergreen, in deciduous forest, and in 

 bamboo brakes. Gyldenstolpe notes that he saw it only on the lower
