The White-winged Scoter might be characterized as a Sea Duck 

 that retires inland to breed. It occurs in summer, and builds from 

 about latitude 50° to the fur countries, and winters on the Massa- 

 chusetts coast and south to Chesapeake Bay. Some few individuals 

 are found in wdnter on the Great Lakes. 



The habits of these birds do not differ from others of the group. 

 Their principal food is moUusks, which they obtain by diving, 

 generally in deep water ; and they are most active at night, float- 

 ing on the water asleep during a great part of the day. Their note 

 is a harsh ke7'-ker.

 wanders occasionally to the coasts of Greenland.
