This species was first shown to be specifically distinct from those of Europe by Dr. Sharp- 

 less. It breeds in high northern latitudes, and enters the United States through the interior, 

 a few only appearing along the coast. In the uninhabited regions of Hamilton and Herkimer 

 counties in this State, this species, as I was informed by trustworthy hunters, remains during 

 the whole year, where it must necessarily breed. The outlet of Lake Paskungameh, or 

 Tupper's lake, was specified as a spot to which they were particularly attached. The eggs 

 are from five to seven in number, greenish. It is very common on the Chesapeake bay during 

 the winter. Abundant also on the Pacific coast of America.
