Habitat, Temperate North America, especially along the Atlantic coast of the United 

 States, but also on the larger inland waters, Up the Pacific coast to California. South 

 into the Antilles and Middle America generally. Apparently winters beyond the United 

 States. 



Not common and apparently very irregular spring and fall migrant. 

 Audubon states that it " is extremely abundant at times on the lakes 

 and on the Ohio," which is not confirmed by recent observations. Mr. 

 Winslow does not give it as a bird of Northern Ohio, but Mr. Langdon 

 notes several specimens taken in the vicinity of Cincinnati. I saw a 

 pair on the canal below this city several years since.

Webs deeply incised (feet little more than semipalmate). Tail merely emarginate^ 

 hardly or not half as long as the wing.
