BLACKPOLL WARBLER 



197 



General Distribution. — Eastern North America ; north to the Kmit 

 of tree growth, Labrador to Alaska ; west to the Rocky Mountains. 



Sutnmer Range. — Principally in Canada, b'ut a few nest south to 

 northern Maine (Franklin and Washington Counties), the mountains 

 of New Hampshire, Vermont, and New York, and, probably, to 

 northern Alinnesota (Leach Lake). The southernmost breeding record 

 is at Seven Lakes, near Manitou, Colorado, at an altitude of 11,000 

 feet. The Blackpoll occurs sparingly in Colorado, less commonly in 

 New Mexico (in migration) and northwest through Montana to 

 Yukon and Alaska. 



Winter Range. — Northern South America to Ecuador, Guiana 

 and eastern Brazil. 



Spring Migration. — No Blackpoll Warbler seems to spend the 

 winter north of South America, while the southernmost breeding 

 grounds are in northern New York and central, Colorado. Therefore, 

 no Blackpoll Warbler can have a migration route less than twenty-five 

 hundred miles in length, and the extremes of the range — Alaska and 

 Brazil are twice that distance apart. It is one of the very few War- 

 blers that migrate directly across the West Indies from South America 

 to Florida. This species is correctly considered one of the latest 

 migrating Warblers, and is seldom seen in the Gulf states before the 

 last week in April. It makes the trip from Florida to Maine at twice 

 the speed of the Black and White Warbler, and the individuals that 

 nest in Alaska travel at an average speed of not less than seventy-five 

 miles per day.
