BACHMAN'S WARBLER 

 SPRING MIGRATION 



One of the early migrants, it crosses to the United States in March: 

 Sombrero Key, Fla., March 3, 1889; Suvvanee River, Fla., March 12, 

 1890; Branford, Fla., March 14, 1892; Old Town, Fla., March 10, 1893; 

 Wacissa River, Fla., March 13, 1894; Leon County, Fla., March 22, 

 1904; Bay St. Louis, Miss., March 26, 1902; Lake Pontchartrain, La., 

 Feb. 27 to March 14, 1891. 



FALL MIGRATION 



The southward migration begins so early that in July many individuals 

 reach their winter quarters. Earliest at Key West, Fla., July 17, 1889; 

 latest, September 5, 1888. 



SWAINSON'S WARBLER 

 SPRING MIGRATION 



The earliest recorded spring arrival in the United States was on March 

 22, 1890, on the Lower Suwanee River. The same year the species was 

 taken at the Tortugas, March 25 to April 5. The other records of first 

 arrival in spring are: Sombrero Key lighthouse, April 3, 1889; Savannah, 

 Ga., April 8-16, 1894; Kirkwood, Ga., May 4, 1898; Frogmore, S. C, 

 April 1-5, 1885; New Orleans, La., April 8, 1898, April 1, 1904, March 

 30, 1905; Bayou Sara, La., April 8, 1887; Coosada, Ala., April 12, 1878. 



FALL MIGRATION 



This begins rather late when compared with the date of nesting. 

 Fledged young have been seen near Charleston, S. C, by June 9, but the 

 earliest date of striking at Sombrero Key lighthouse is August 17, 1888; 

 other dates at this lighthouse extend from September 14, 1884, to October 

 26, 1885, and at Key West, Fla., from the middle of September to Sep- 

 tember 20.
