NORTH AMERICAN FAUNA 69 



August and the Florida Keys by mid- August and early September. 

 Migrants were reported at Gulfport, Miss., on August 8 and 19, 

 and at Deer Island, Miss., on August 26 (Burleigh, 1945, p. 110) ; 

 at Sombrero Key, Fla., on August 17 (Howell, 1932, p. 386) ; and 

 at Dry Tortugas, Fla., by September 2-9 (Sprunt, 1951, p. 224). 



Late records of departure are : Knoxville, Tenn., October 7 and 

 8 (Howell and Tanner, 1951, p. 62) ; Tybee Island, near Savannah, 

 Ga., October 18 (distribution files. Migratory Bird Populations 

 Station) ; Tallahassee, Fla., October 14 (Stoddard and Norris, 

 1967, p. 71) ; and Sombrero Key, Fla., November 8, 10, and 13 

 (Howell, 1932, p. 386). 



The migration route to the wintering grounds is apparently 

 the reverse of that to the breeding grounds. The distribution of 

 casualties at the base of the Tall Timbers TV tower indicates 

 that the heaviest flight is from northeast to southwest, the direc- 

 tion of trans-Gulf migration. Some birds that migrate through 

 southern Florida also pass through the Tallahassee area in the fall 

 (Stoddard and Norris, 1967, p. 71). 



The coast of Georgia and the eastern coast of Florida are also 

 a southward migration route, as evidenced by the following rec- 

 ords: Tybee Island, Ga., September 23 and 24 and October 2 and 



18 (Burleigh, 1958, p. 496) ; Jacksonville, Fla., October 5 and 7, 



19 birds picked up at TV towers (Cunningham, 1965, p. 29) ; St. 

 Augustine, Fla., September 14 (distribution files. Migratory Bird 

 Populations Station) ; Miami, Fla., October 2 (L. A. Stimson, 

 distribution files. Migratory Bird Populations Station) ; and 

 Loxahatchee National Wildlife Refuge, Fla., October 6 (P. W. 

 Sykes, Jr., personal communication). 



Southward movement along the Gulf Coast in Texas and north- 

 ern Mexico would be expected, but records are fewer for the fall 

 than for the spring: Rockport, Tex., October 20 (C. H. Hagar, 

 distribution files, Migratory Bird Populations Station) ; Kemak, 

 Tex., September 27 (J. S. Heiser, distribution files. Migratory 

 Bird Populations Station) ; and Matamoros, Tamaulipas, Mexico, 

 just over the Texas border from Brownsville, August 29 (Phillips, 

 1911, p. 84). 



Early arrival records in the West Indies are: Havana, Cuba, 

 September 25 (Bent, 1953, p. 38) ; and Mt. Elizabeth, Jamaica, 

 October 1 and 7 (Merriam, 1885, p. 377).
