302 THE POOD OP BIRDS IN INDIA. 



Their food appears to be largely animal, though of course they 

 feed partly on vegetables. F. I. IV, 464. 



Its food is almost entirely animal, much the same, in fact, 

 as the scaup, but it is far more a fresh water bird, and far less 

 a sea bird than is that duck. S. B. I. D. A., 243. 



1610. Clangula glaucion. Golden-eye. 



(Macgillivray) Their food consists principally of the larvaB of 



aquatic insects, for which they dive in the clear water They 



also feed on small fresh-water mollusca ; but I have not observed 



any vegetable substances in their oesophagus or stomach In 



one instance I have seen remains of small fishes in the gizzard. 

 ....Especially in frosty weather, resort to estuaries, as well as 

 the open coasts, where they procure testaceous mollusca, crus- 

 tacea and fishes. (Yarrel) Principally of small fishes. H. M. 

 G. B. Ill, 286. 



The stomach contained fish weeds and seed. It is said to feed 

 on "Testaceous mollusca, Crustacea and fishes' also on water 

 insects and grubs, and, but not often, also on vegetable food, 

 principally deep-water weeds, roots and similar articles. Food 

 consists almost entirely of animal matter procured by diving. S. B. 

 I. D. A., 249-252. 



Erismatura. The food is of fish, molluscs, and insects. E. 

 B. C. Nv H., 118. 



1611. Erismatura leucocephala. White-headed Duck. 



They are said to feed on water insects, small fishes, and 

 shells as well as vegetable matter ; but I suspect that this is rather 

 conjectural. H. M. G. B. Ill, 291. 



SUB-FAMILY. Mergince. Mergansers live chiefly on fish, but 

 the bill of fare is varied by grain, pulse, berries, frogs, insects, 

 jarvas, worms, molluscs, and crustaceans. E. B. C. N. H., 114. 



Their food consists of little but fish. E. B. C. N. S., 116. 

 Chiefly on fish. Jerd. B. I. Ill, 817.
