nois,t Mr. E. W. Nelson speaks of it as an "Abundant migrant. 

 Breeds sparingly away from the Lake'." 



The range of the Chestnut-sided Warbler covers the United 

 States, east of the Plains. It breeds from about the latitude of 

 central Illinois northw^ard to the southern portion of the British 

 Possessions and as far west as Manitoba, and in the Alleghanies 

 as far south as Georgia. It winters from the Bahamas and 

 eastern Mexico southward at least to Panama.

As a rule, the Bay-breasted Warbler is a common migrant, 

 although some seasons it is rather uncommon in its passage 

 through our area. In the spring it arrives from the last of April 

 to the last of May, and returns in the fall from the last of August 

 to the last of September. 



The range of this Warbler covers the United States east of 

 the Great Plains, breeding from northern New England and 

 northern Michigan nprthward. It winters southward through 

 eastern Mexico and Central America to northern South America.

The Black-poll Warbler is a common migrant, arriving in the 

 spring during the month of May, and returning in the fall from 

 about the tenth of September to the fourth of October. 



The range of this Warbler extends over North America east 

 of the Rocky Mountains, and it breeds from the Catskill Moun- 

 tains and northern New England northward to Alaska and Green- 

 land. In the winter it migrates southward through the West 

 Indies to South America where it is found as far south as Brazil 

 and Chili. It has not been recorded from either Mexico or Cen- 

 tral America, though during its migrations it has been observed 

 in New Mexico.
