The True Ducks. 235 



This Duck extends through Bengal and 

 Assam, and has been obtained in Tipperah, 

 Sylhet, Manipur and Arrakan. Captain 

 F. T. Williams informs me that it occurs 

 on the Chindwin river. Captain T. S. 

 Johnson found it common near Mandalay, 

 and Major G. Rippon writes to me that, 

 in his opinion, this is the commonest duck 

 in Upper Burma, Teal alone excepted. I 

 have not heard of its occurrence south of 

 the Mandalay District. 



The Gadwall, like many other species 

 of the True Ducks, has a very wide dis- 

 tribution, but does not reach quite so far 

 north in summer, being found up to the 

 Arctic Circle, but, as far as we know, 

 never within it. It occurs alike in 

 North America, Europe and Asia. In 

 the winter it ranges south to Mexico, to 

 Northern Africa, South-western Asia, 

 India, Burma and China. 



Gadwalls may be seen in the Himalayas 

 towards the end of September, but they 

 are not fully established in the plains till 

 the end of October or the beginning of 

 November. They return north in March 

 and April, and they are sometimes still to 

 be met with early in May in the North- 

 west.
