THE BIRDS OF NORTHERN THAILAND 253 



feet in ravines; on Doi Chiang Dao, de Schauensee took it at 4,600 

 feet. 



This little bird, in all its actions, is like the larger woodpeckers. I 

 have seen it feeding on the trunks of saplings and on the stems of 

 bamboo and exploring the apical twigs of the lower branches of the 

 trees. For drumming purposes it seeks a hollow limb or dry bamboo, 

 by means of which it can produce a sound as loud as that of a much 

 larger species. 



A male taken by me had the irides brown ; the bill slaty ; the feet 

 and toes plumbeous. 



The adult male has the forecrown orange, each feather with an ex- 

 posed black base; the hindcrown and nape grayish olive, changing 

 to deep olive-ochre on the remaining upperparts; the rectrices black, 

 the central pair with the inner web white, the others with a broad, 

 diagonal, subterminal white bar; a white line, broadening posteriorly, 

 from above the eye to the nape ; a second from the base of the bill down 

 the side of the neck ; the area between the two lines dark brown ; the 

 remaining underparts pale yellow (whiter on the throat and upper 

 breast), boldly marked with black spots, which gradually change to 

 bars on the lower flanks. The adult female differs only in having the 

 entire crown grayish olive.

This piculet is uncommon and local in the lowland districts of 

 Chiang Eai, Phrae, and Nan Provinces (Muang Fang, Wiang Pa Pao, 

 Chiang Eai, Chiang Saen, Ban Pha Khwang, Ban Huai Ki), very 

 rare on the plains (Chiang Dao, Chiang Mai) and mountains (Doi 

 Chiang Dao, Doi Ang Ka) of Chiang Mai Province. The only record 

 for Chiang Mai Town is a solitary individual seen in a dense clump 

 of giant bamboo, July 2, 1930. 



The predilection of the rufous piculet for extensive brakes of bamboo 

 may account for its broken distribution. The only example observed 

 on Doi Ang Ka, however, was climbing about on a reedlike grass in a 

 clearing amid wild bananas at about 5,000 feet. 



My specimens had the irides bright crimson ; the orbital skin deep 

 crimson or crimson-lake; the maxilla plumbeous or slaty; the man-
