WESTERN PALM WARBLER 447 



British Columbia (Trutch and Miniker Eiver) . West to northeastern 

 British Columbia (Miniker Kiver and Fort Nelson) and southwestern 

 Mackenzie (Simpson). Judging from the data on migration of the 

 palm warbler the northern limit of the breeding range is in the un- 

 explored regions to the north, possibly the limit of trees. 



The palm warblers which occupy the range as outlined are divided 

 into two geographic races: the western palm warbler {D. p. pal- 

 marum) breeds east to central Ontario, while the eastern part of the 

 range is occupied by the yellow palm warbler D. ip. liypochrysea) . 



^Y^nter range. — The palm warbler winters regularly north to cen- 

 tral Louisiana (Alexandria) ; central Alabama (Prattville) ; northern 

 Georgia (Atlanta and Athens) ; and northern South Carolina 

 (Chester). It is casual in winter north to Bicknell, Ind. ; Columbus, 

 Ohio; Toronto, Ontario; Doylestown, Pa.; Garden City and Shelter 

 Island, N. Y. ; and Martha's Vineyard, Mass. East to South Carolina 

 (Chester and Charleston) ; eastern Georgia (Savannah and Bruns- 

 wick) ; eastern Florida (Fernandina, St. Augustine, New Smyrna, and 

 Miami) ; the Bahama Islands (Nassau, Watling, and Caicos) ; 

 Hispaniola (Sanchez) ; Puerto Rico (San Juan) ; and the Virgin 

 Islands (St. Croix). South to the Virgin Islands (St. Croix); 

 Jamaica ; and Providence Island. West to Providence Island ; north- 

 ern Honduras (Roatan Island) ; Quintana Roo (Banco Chinchorro) ; 

 Yucatan (La Vega and Progresso) ; and Louisiana (Chenier au Tigre 

 and Alexandria ) . 



The two races of the palm warbler tend to cross each other's routes 

 in migration. The eastern form is more abundant in the western part 

 of the winter home, while the western form is commoner in southern 

 Florida and the West Indies.
