 within the Arctic Circle. It breeds north to northern Ungava in Quebec, 

 northern Ontario, central Keewatin, northern Mackenzie, and northern Alaska; 

 west to western Alaska; south to southern Alaska, central Alberta, southern 

 Wisconsin (casually), central New York, southern Maine, and New Brunswick; 

 and east to Nova Scotia and Newfoundland. It winters north to Nebraska, 

 Michigan, and southeastern New York, arid south to the Gulf of Mexico, 

 from Florida to eastern Texas. It occurs casually in migration west to British 

 Columbia, Montana, and Colorado, and accidentally in California, Lower 

 California, and Greenland,
