BIRDS FROM SIAM AND THE MALAY PENINSULA 223 



1932; one male and two females, Pak Chong, May 15, 1925, December 

 20, 1926, November 21, 1929; one male, Pang Sok, August 26, 1926; 

 one male, Lat Bua Kao, July 30, 1929. 



This form ranges from the Shan States, central and southern Burma, 

 to northern, southwestern, central, and eastern Siam. Robinson and 

 Kloss ^' record it from Tapli, Pakchan Estuary, which is about as far 

 to the southwest as it ranges. It is rarely found far away from bamboo 

 jimgle. De Schauensee ^° collected specimens at Tamuang, Chanta- 

 bun, Kanburi, and Chieng Dao and states that the specimen from 

 Cliantabun is slightly darker below than the birds from the three 

 other localities. Gyldenstolpe ^^ found it not uncommon at Doi Par 

 Sakeng and Kliim Tan, northern Siam. Chasen and Kloss ^^ record 

 it from the Raheng District in the western part of the country. 



In the above series specimens in fresh unworn plumage are dis~ 

 tinctly green below; as they wear and fade they become quite brown 

 on the lowerparts. It is quite necessary when comparing birds from 

 different geographic areas to use specimens in fresh plumage.
