 limits of neither are as yet definable. Gyldenstolpe found it in 

 N. Siam and specimens from the Shan States and Ynnnan are 

 also referable to this form. It will probably also be found in the 

 S.E. Kachin States. 



Nidification. Unknown. 



Habits. Gyldenstolpe records that he found it shy but not un- 

 common in some places in North Siam, frequenting dense primeval 

 forests in small flocks.
