This form breeds in southeastern Siberia, Manchuria, and China, 

 and migrates to Indo-China, Burma, Siam, and the Malay Peninsula 

 to winter. 



In Siam proper it is a common winter resident nearly all over the 

 country. In Peninsular Siam it is less common from Trang southward. 



Williamson ^^ states that it arrives at Bangkok in October and 

 leaves in April. Robinson ^^ records it from Koh Kut, Koh Chang, 

 Koh Rang, and Ok Yam. The United States National Museum has

 Kloss. It has been recorded from other islands off the coast of Penin- 

 sular Siam also.
