HABITS. 



The Shovellers, although quite common in the West, are exceedingly rare in Now Eng- 

 land, but I found them very abundant in the shallow pools on the marshes of Salt Lake and 

 Indian River, Florida. Here they fed in little groups, and JH they were quite unsuspi- 

 cious, could be easily approached and shot. I have also taken specimens at Key West in 

 winter. These fine Ducks may possibly breed in Florida, as I have found them common 

 there quite late in the season.
