of Neuroptera and Lepidoptera) and their larvae, worms, grubs 

 and small fishes. H. M. G. B. Ill, 269. Practically omnivorous, 

 like most ducks, it appears to feed to a considerable extent on 

 insects and their larvae, Crustacea and mollusca. F. I. IV, 461. 

 Omnivorous, like all ducks, this species probably makes its diet 

 fully f animal. Those birds which I shot in the Diyang and other 

 hill streams had all (in addition to the Caddis grubs, dragon fly 

 larvae, and similar articles) quite a number of small fish, some of 

 them three inches in length. These were nearly all of the " millers 

 thumb *' species, so common in every hill-stream. S. B. I. D. 

 A., 230. 



1608. Nyroca marila. Scaup. Feed on mud flats ; although 

 in a wild state, it feeds chiefly on marine mollusca, yet it soon 

 accustoms itself to feeding on vegetable matter, and will freely eat 

 grain, especially barley. H. M. G. B. Ill, 273. Derives its name 

 from feeding on mussels. F. I. IV, 463. The food of the scaup is 

 everywhere chiefly of an animal character. Inland, doubtless, it 

 feeds to a certain extent on water weeds, etc., these being mainly 

 such as grow at some depth and are obtained by diving ; but even 

 here shell fish, frogs, insects, form the greater part of its diet. 

 When in its natural element, on sea in creeks, or along the 

 coast, it is almost entirely an animal feeder, subsisting on 

 shell-fish, small fish, and other marine small life. Its name is 

 derived from its habit of feeding on mussels. S. B. I. D. A., 

 237. 



1409. Nyroca fuliyula. Tufted Duck. It feeds on water 

 insects and mollusca. Jerd. B. I., Ill, 815. Their food is perhaps 

 more animal than vegetable. They constantly devour small fish, 

 and one finds every kind of water-insects, worm, grub and shells, 

 small lizards, frogs, spawn, etc., in their stomachs. Still, like the 

 rest they eat leaves, stems and roots of water plants freely, and 

 I have several notes of birds which had dined ,or breakfasted 

 entirely off some white shining onion-like bulb. H. M. G. B. 

 Ill, 281,
