The Migration of Warblers 



193 



and at Omaha, Nebr., August 25 to September 10. The latest Florida 

 record is of a bird that struck the light at Sombrero Key, September 25, 

 1888, and the latest from New Orleans is September 24, 1893. The only 

 iall record for the West Indies is of one taken at New Providence, Baha- 

 mas, August 28, 1898. 



The route of the Prothonotary Warbler in fall migration is interesting, 

 because apparently the breeders of the Middle Atlantic states pass south- 

 west to northwestern Florida and then take a seven-hundred-mile Hight 

 directly across the Gulf of Mexico to southern Yucatan, instead of crossing 

 to Cuba and thence to Yucatan. 



What Bird is This ? 



Field description. — Length, about 7.00 inches. Above brownish, edged with buffy on back and wings; below 

 much paler, streaked with baSy and grayish; throat white or whitish. 



Note. — Each number of Bird-Lore contains a photograph, from specimens in 

 the American Museum of Natural History, of some comparatively little-known bird, or 

 bird in obscure plumage, the name of which will be withheld until the succeeding number 

 of the magazine. It being believed that this method of arousing the student's curiosity 

 will result in impressing the bird^s characters on his mind far more strongly than if its 

 name were given with the picture. 



The species figured in October is the male Mourning Warbler.
