13.— Cuncuma leucogaster, Gmel. (43.) 



The Grey-backed Sea Eagle is by no means rare in Chota 

 Nagpur, being found in the vicinity of all the larger rivers. 

 It is extremely wary and difficult of approach, generally taking 

 flight when it first sees danger. The only specimen I 

 obtained is now in the Museum of the Royal Dublin Society 

 together with some other birds of my early collections. In Dr. 

 Dobson's collection from the Andamans which I described, there 

 were several specimens. I have seen it in almost all the islands 

 of the Nicobar, Andaman and Coco groups. 



The insular bird seems, when on the wing, to be somewhat 

 larger than continental specimens. I have had no opportunity 

 however of comparing them side by side.
