72 NORTH AMERICAN WARBLERS. 



at Sea Isle City, near the coast at the extreme southern end of New 

 Jerse}^ In the Allegheny Mountains the bird breeds much farther 

 south. During the breeding season it is common to abundant in the 

 mountains of North Carolina at an elevation of 2,000-4,000 feet and 

 not uncommon at corresponding elevations in the northwestern part 

 of South Carolina. It probably breeds sparingly in northern Georgia. 



Winter range. — The chestnut-sided warbler winters from Guatemala 

 to Panama, both on the coast and in the lower mountains. It is abun- 

 dant along the coast of southeastern Nicaragua^ and less common 

 throughout Guatemala. There are four records of its occurrence in 

 Honduras — at San Pedro and Truxillo,^ on the north coast, and on the 

 islands of Bonacca^ and Ruatan.^ The onl}^ record for Yucatan ^^ is of 

 a specimen taken at Merida April 18, 1865. There are records from 

 Costa Rica which denote that the species occurs in September on the 

 high plateaus,^ is abundant during the fall migration, and rare in the 

 spring at San Jose-^ (3,500 feet), and was common during the fall of 

 1895 on the Pacific slope at Miravalles^ (1,400-2,000 feet). The only 

 Mexican records, probabl}^ all made during migration, are of speci- 

 mens taken in April at Pla3^a Vicente^* on the hot lowlands of Oaxaca; 

 on May 16, 1888, at Can3^on Cavelleros, Tamaulipas; and at Jalapa,^ 

 State of Vera Cruz. 



Late writers have commonly included the Bahamas in the winter 

 range of the chestnut-sided warbler. Nearl}^ half a century ago Bry- 

 ant recorded that he saw in May a few of the species on the island of 

 New Providence. These were undoubtedl}" spring migrants tliat had 

 wandered far out of their usual course. Years afterward a writer 

 quoted this note as a winter record, and his mistake has been perpetu- 

 ated. Other records of Avandering birds were made at the Bermudas 

 in the spring of 1901 ; at Enterprise, on the east coast of Florida, soon 

 after the middle of ]March; near the mouth of the Suwanee River, 

 Florida, April 10, 1892. 



Sj)ring migration. — The records of spring migration of the chestnut- 

 sided warbler in the United States south of the latitude of Washington 

 and St. Louis are entirely without regularity. For the sake of having 

 the material on record, the dates are here given :
