All three species of Surf Scoters, or " Coots," are abundant winter 

 residents off the coasts of the New England and northern Middle 

 States. At this time their habits are practically alike — indeed, they 

 are often found associated. As a rule, they frequent only the sea 

 and its estuaries, where they live over beds of mussels, clams, or 

 scallops, which they obtain by diving; but they are sometimes found 

 in ponds near the coast, where food of this nature is abundant. 



In The Auk for 1891, pp. 279-290, Mr. George H. Mackay gives the 

 results of a long-continued study of Scoters on the Massachusetts 

 coast.
