 Tex., May 1, 1884, April 22, 1891, April 19 and 29, 1900. The species 

 is a rapid migrant, being present scarcely more than three weeks 

 during spring migration at any point in the Gulf States. North of 

 this district some records of average date of arrival are: French- 

 creek, W. Va., May 2; Washington, May 3; Beaver, Pa., May 2; 

 Renovo, Pa., May 3; southeastern New York, May 6; Boston, May 

 6; southern New Hampshire, May 8; Lewiston, Me., May 12; Mon-

 Halifax, Nova Scotia, was noted on May 24. 



Fall migration. — Migrating chestnut-sided warblers were noted at 

 Englewood, N. J., July 26, 1887; Washington, August 10, 1889, and 

 Frenchcreek, W. Va. , September 6, 1892. The earliest recorded 

 arrival of the species in fall at Raleigh, N. C. , was on August 17, 1891. 

 In Chester County, S. C, the bird has been noted as early as August 

 16. The first arrivals were noted at San Jose, Costa Rica, September 

 28, 1889, and September 21, 1890. The bulk- of the species passes 

 through the Carolinas in September, reaches the Gulf coast the latter 

 part of the month, and arrives at Costa Rica by the middle of October. 

 The bird was taken at Truxillo, Honduras, September 26, 1887. The 

 last southbound migrants were noted at Ottawa September 12, 1885; 

 St. John, New Brunswick, September 10, 1895; Berwyn, Pa., October 

 8, 1891; Washington, September 29, 1889; and Frenchcreek, W. Va., 

 September 28, 1890. In the Southern States stragglers occur until 

 after the middle of October. It is thus seen that at the south end of 

 the Allegheny Mountains the fall migration of the chestnut-sided warbl er 

 lasts fully two months, while the spring migration occupies not more 

 than three weeks. 



Fall migration in the Mississippi Valley is not very different from 

 that in the East. The earliest recorded arrival at St. Louis was on 

 August 24, 1896, and the average date of earliest arrival at New 

 Orleans for several years was September 15. Chestnut-sided warblers
