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

 ment as to the species of warblers, if an}^, that cross from Cuba to 

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

 (Dol{cho?iyx orj/2tvorus) and Florida kingbird {Tyrannies doDiinicensis)^ 

 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, onl}" the following 6 occur regularly in Cuba.
