 This species, like the preceding one, is a fairly common bird in 

 the wooded districts of all our provinces, occurring not only in de- 

 ciduous forest but also in the evergreen and ascending the hills at 

 least to 5,500 feet. 



Not only are the two golden-backed woodpeckers strikingly similar 

 in appearance but they agree in voice and habits and may even, on 

 occasion, be observed on the same tree trunk. 



Smith took a juvenile male on the Burmese bank of the Salwin, 

 January 28. I collected molting adults at a number of localities 

 between April 21 and August 15. 



Gyldenstolpe records that his specimens had the irides yellowish 

 red; the bill slate; the feet and toes olive-green. 



The golden-backed woodpeckers are superficially so much alike that 

 it is scarcely necessary to give a detailed description of the present 

 form. The four-toed species differs, inter alia, in the following 

 characters: it is a distinctly larger bird, with a much longer, more 

 robust bill ; at each side of the throat, from the base of the mandible, 

 it has two narrow black lines, which fuse posteriorly into one; the 

 female has a round white spot near the tip of each feather of crown 

 and crest.
