Not enough data have been accumulated to permit any exact state- 

 ment as to the species of warblei's, if any, that cross from Cuba to 

 South America. It is known that some other birds, as the bobolink 

 {Dolichonyx oryzivorus) and Florida Icingbird (Tyrannus dominicensis), 

 pass over this route in large numbers. That warblers seldom cross 

 the Caribbean Sea is probable from the fact that of nearly a score of 

 species that occur in the eastern United States and also in South 

 America, only the following 6 occur regularly in Cuba. 



SPECIES THAT OCCUR IN BOTH CUBA AND SOUTH AMERICA. 



Black and white warbler {Mniotilta varia). 

 Black-poll warbler {Dendroica striata). 

 Oven-bird {Seiurus aurocapillus). 

 Water-thrush {Seiurus noveboracensis). 

 Louisiana water-thrush {Seiurus motacilla). 

 Redstart {Setophagaruticilla).
