SUBFAM. Cygnince. Swans. Swans feed on the seeds and

1577. Cygnus olor. Mute Swan. They feed chiefly on aquatic 

 plants, partly on insects and their Iarva3, molluscs, etc. F. I.

1578. Cygnus musicus. Whooper. These swans are, I fancy, 

 chiefly vegetarians, feeding mostly on herbs, and their seeds and
