FALL MIGRATION 



The southward movement begins the last of July, and on October 7 the 

 species has been taken at the extreme southern limit of its known range in 

 Colombia, South America. Some records of the latest observations are at 

 Berwyn, Pa., September 4, 1896; Beaver, Pa., September 13, 1888; Cadiz, 

 Ohio, September 23, 1900; Eubank, Ky., September 6, 1888; Raleigh, 

 N. C, September 12, 189+ ; New Orleans, La., October 19, 1895. 



CONNECTICUT WARBLER 



This is one of the few species that seem to travel different routes during 

 the two yearly migrations. The spring migration is through Florida to the 

 Mississippi Valley and thence north to the breeding grounds. The few 

 records of spring migration note the arrival of this species in southern 

 Florida, May 4-19; northern Florida, May lo-ji ; Chester county, S. C,
