MICROPTERNUS BRACHYURUS PHAEOCEPS Blyth 



Microplernus phaeoceps Blyth, Proc. Asiat. Soc. Bengal, vol. 14, p. 195, 1845 

 (Arracan). 



One female, Doi Nangka, November 16, 1930. 



This is the only specimen of this woodpecker collected by Dr. 

 Smith in northern Siam. It does not exactly agree with a specimen 

 from the Raheng District identified as burmanicus by Chasen and 

 Kloss ^* or with a specimen from Thayetmyo, Pegu, the type locality 

 of that form. It is darker than the Raheng specimen above, with 

 heavier dark bars; below it is much darker, the breast becoming dusky 

 with darker sub terminal bars and buffy edgings to the feathers; the 

 feathers of the throat have much darker centers and are more widely 

 edged with light buff. In the Raheng specimen the centers of the 

 throat feathers are the same color as the chest and the edgings only 

 slightly paler. 



The Nangka specimen, compared with the one from Thayetmyo, 

 has the upperparts more heavily barred; the centers of the throat 

 feathers are much darker and the buffy margins broader; the feathers 

 of the pileum in the Nangka bird have a dark-brown central stripe 

 with lighter edgings, while in the Thayetmyo bird the pileum is a 

 dusky brown without any lighter edging to the feathers. 



The female from Doi Nangka measures: Wing, 132; tail, 67; culmen, 

 26 mm. The female from Raheng: Wing, 129.5; culmen, 26.5 mm. 



This form apparently ranges from Tenasserim (except the extreme 

 southern tip) north to the Shan States and eastward to western and 

 northern Siam. 



Deignan ^^ reports it common at Chiengmai, and other collectors 

 have found it not uncommon in northern Siam. De Schauensee ^® 

 secured specimens at Chiengdao, Tung Sio, and Chiengmai. Gylden- 

 stolpe ^^ reports it from Den Chai and Pak Pan and on liis second 

 expedition *^ from Doi Par Sakeng and Khun Tan ; Chasen and Kloss *9 

 listed it under the name M. b. burmanicus from the Raheng district^
