68 TTORTH AMERICAN WARBLEES. 



inOaxaca, Mexico; Richmond saw none after February 5 in Nicaragua; 

 and along the eastern coast of Yucatan, where there was previously but 

 a single record of occurrence, the parties of the Biological Survey found 

 them in spring migration common to April 13. Some records of latest 

 dates on which the birds w^ere noted in spring in the southern part of 

 the United States are as follow^s: Key West, Fla., May 17, 1887; Dal- 

 las, Tex., May 18, 1898; Helena, Ark., May 16, 1897; Shelby, Ala., 

 May 12, 1898; St. Louis, May 18, 1881, May 22, 1885, May 18, 1887. 



Fall migration. — Over much of the southern part of the United 

 States the magnolia warbler, though rare in spring, is common in fall. 

 The first fall migrants have been noted at Lanesboro, Minn., August 

 12, 1887; Grinnell, Iowa, August 20, 1886; Chicago, August 12, 1896; 

 Englewood, N. J., and Washington, August 16, 1889; and Raleigh, 

 N. C, September 11. In Chester County, S. C, the fourteen-year 

 records of Loomis show that the earliest arrival from the North during 

 that time Avas on September 3; that the bird is not uncommon in Sep- 

 tember; that the main body of migrants arrive about October 1; and 

 that all are gone before October 15. Latest dates on which fall migrants 

 were noted are: Aweme, Manitoba, September 17, 1900; Lanesboro, 

 Minn., September 12, 1889; Ottawa, September 19, 1895; North River, 

 Prince Edward Island, September 8, 1890; St. John, New Brunswick, 

 September 7, 1890; Chicago, October 9, 1891; Philadelphia, October 

 9, 1888; Washington, October 10; and Asheville, N. C, October 10, 

 1891. At New Orleans the species is one of the common fall migrants. 

 During three 3^ears the average date of earliest arrival was September 

 18; the birds Avere present in largest numbers from September 25 to 

 October 7; and the dates on Avhich the latest migrants were noted 

 ranged from October 23, 1897, to November 1, 1895. South of the 

 United States the magnolia warbler has been taken at Truxillo,^ 

 Honduras, September 27, 1887, and the first arrival has been noted in 

 southeastern Nicaragua,* October 27, 1892. 



The general path of migration of the species seems to cross the mid- 

 dle of the Gulf of Mexico. It is bounded approximately on the east 

 b}" a line drawn from the north central part of Georgia to eastern 

 Yucatan, while few individuals seem to proceed farther west than 

 the coast line from eastern Texas to southern Vera Cruz. In common 

 with some twenty other species of birds the magnolia warbler seems to 

 make its flight between the L^nited States and Yucatan without taking 

 advantage of the peninsula of Florida or using Cuba as a stopping 

 place. At the southern end of the Allegheny Mountains it is a com- 

 mon migrant, while it has been noted only three times in Florida and 

 only once in Cuba.
