When the surface of Lake Michigan is quite frozen over, 

 large flocks of these ducks may be seen about the airholes, or 

 they may be seen among the ice floes, in company with Old-squaw 

 Ducks (Harelda hyemalis), and White-winged Scoters (Oidcinia 

 deglandi). A common winter resident. 



The range of the Golden-eye covers nearly the whole of North 

 America and it breeds from the northern border of the United 

 States northward.

A rare winter visitant. I have a specimen of this duck which 

 I shot on Lake Michigan, near the Daily News Sanitarium, 

 December n, 1896. The bird was flying in company with an- 

 other, probably of the same species. 



This Golden-eye is a bird of the far north passing southward 

 in winter only as far as New York, Illinois and Utah. It breeds 

 north of. the United States and also in the Rocky Mountains as 

 far south as Colorado.

Formerly the Duffle-heads were common, but now they are 

 rather uncommon. At the time of their fall migration, they 

 arrive in October and remain until the last of April. While they 

 are often seen on Lake Michigan, they are much more common 

 on the smaller inland lakes. Very often they will exhibit a 

 peculiar habit of flying directly toward the gunner after being 

 shot at, thus affording a second chance for a shot. 



The Buffle-heads breed north of the United States, and in 

 winter pass as far southward as Cuba and Mexico.
