The Migration of North American Birds 



SECOND SERIES 



XX. BALTIMORE ORIOLE 



Compiled by Harry C. Oberholser, Chiefly from Data in the Biological Survey 



The Baltimore Oriole {Icterus galbula) is one of the best-known birds of the 

 eastern United States, and a favorite ahke with country and city bird-lover. 

 Its whole range extends from southeastern and central southern Canada south 

 through the eastern half of the United States to Central America and northern 

 South America; and the species is as yet undivided into subspecies. It breeds 

 north to Nova Scotia, Prince Edward Island, New Brunswick, southern 

 Quebec, southern Ontario, central Saskatchewan, and central Alberta; west 

 to central Alberta, eastern Montana, western South Dakota, eastern Colorado, 

 northwestern Texas, and eastern Texas; south to southern Louisiana, central 

 Alabama, and central Georgia; and east to central South Carolina, western 

 North Carolina, eastern Virginia, and the Atlantic Coast north to Nova 

 Scotia. In migration it moves southward over the remainder of the southeast- 

 ern United States, including Florida. It winters from southern Mexico through 

 Central America to Colombia. It is of casual occurrence in the Bermuda 

 Islands; accidental at York Factory, Manitoba, and in Cuba.
