Peninsula north to Melville and North Devon Islands, south to west side of Hudeon Bay 
(Churchill). Migrates south chiefly over the Atlantic Ocean from Nova Scotia to the 
north coast of South America, thence to the plains of southern South America from Bolivia 
and southern Brazil south to the pampas of eastern Argentina. The northward migration in 
spring takes place up the Mississippi Valley. 
Distribution in Guatemala.—-Observed at Duefias and along the Pacific Coast during spring 
migration. 
Records.--Not observed during our survey. 
In literature the only record is from Duefias, the second week in April 1858 
(Salvin and Godman).
