americana) a rather common winter resident upon the Lake, and 

 occurs throughout the state, specimens being sent to the Chicago 

 market from the Illinois River and various other streams in 

 Central Illinois." Dr. J. W. Velie also records this Scoter as 

 a winter visitant to Lake Michigan.* 



The White-winged Scoter breeds north of the United States, 

 and winters as far south as the Great Lakes, southern Illinois 

 and Lower California. On the Atlantic coast it winters as far 

 south as Chesapeake Bay.

Mr. E. 'W. Nelson says in his "Birds of Northeastern Illi- 

 nois": "A common winter resident upon Lake Michigan and 

 occurs throughout the state at this season. Quite a number of 

 specimens were taken upon the Calumet Marshes during the fall 

 of 1875, and many others were seen. Arrives the last of October 

 and departs the last of March." I can find no records of its 

 occurrence within our limits since the date in Mr. Nelson's note. 

 Two specimens in immature plumage were taken by Mr. J. Graf- 

 ton Parker at Meredosia, Illinois, on November 9, 1896. 



The range of this species would indicate a probability of its 

 occurrence in our region. "Coasts and larger inland waters of 

 northern North America; in winter south to Florida, the Ohio 

 River, and San Quentin Bay, Lower California."
