A COLLECTION OF BIRDS FROM N. E. SUMATRA. 79 



Immature birds have the barring on the sides of the breast 

 and flanks much less decided. The species is a bird of open 

 country and grass lands and in most places, if not disturbed,, 

 becomes very tame and confiding.

 The dimensions of these birds agree with those from W. 

 Sumatra and are smaller than the form from the Malay Penin- 

 sula, but in this series if the birds are correctly sexed there 

 appears to be no great difference between the sexes in size.
