This more western race of the greater yellow-naped woodpecker is 

 fairly common in the hilly districts east to (and including) the Khun 

 Tan range and is probably the form of all Chiang Rai Province. In 

 Stockholm are four males and two females collected by Eisenhofer at 

 Khun Tan in 1914. I have taken specimens at Muang Fang, Samoeng, 

 Doi Suthep, and Doi Aug Ka. 



This woodpecker is largely restricted to the evergreen, occurring 

 in such forest on Doi Suthep from 2,700 to 5,500 feet, on Doi Ang Ka 

 from 4,400 to 4,900 feet or higher. At Muang Fang, however, it was 

 found in lowland evergreen at 1,400 feet and at Mae Taeng was taken 

 by de Schauensee in lowland deciduous jungle. It agrees in habits 

 with Picus chlorolophus burmae but is perhaps a rather shier bird. 

 The stomach of a specimen from Doi Ang Ka contained ants, ant 

 pupae, and a small green tree frog. 



Breeding probably takes place during the spring months. A bird 

 of July 18 is exceedingly worn and bleached, and all examples ob- 

 tained between September 6 and November 21 are in molt. 



I have noted that an adult male had the irides crimson ; the orbital 

 skin plumbeous; the bill pale plumbeous, tinged horny yellow at the 

 tip, much darker at the base of the mandible; the feet and toes 

 plumbeous; the claws horny plumbeous. Specimens taken by de 

 Schauensee differed in having the irides pinkish white. 



The adult male has the crown and sides of the head dark olive-green, 

 the former more or less strongly suffused with rufous-maroon ; a broad 

 nuchal crest golden-yellow or orange-yellow; the remaining upper- 

 parts bright shining olive-green ; the rectrices black ; the remiges black, 

 broadly banded with rufous ; the chin and throat clear lemon yellow ; 

 the feathers of the foreneck pure white, tipped and often centered with 

 brownish black to give a streaky appearance, the streaked area fre- 

 quently invading the center of the throat; the remaining underparts 

 olive-gray, darker on the breast. The adult female differs in having 

 the yellow of the chin and throat replaced by rufous-brown and the 

 streaked area of the foreneck extending up the center of the throat 

 almost to the chin.
