Cerulean Warbler {Dendroica ceruled). 

 Chestnut-sided Warbler (Dendroica pensylvanica). 

 Bay-breasted Warbler (Dendroica castanea). 

 Blackburn ian Warbler {Dendroica blackburniee). 

 Kentucky Warbler (Geothlypis Jormosa). 

 Mourning Warbler (Geothlypis Philadelphia). 

 Wilson Warbler ( Wilsbnia pusilla). 

 Canadian Warbler ( Wilsonia canadensis). 



The two lists together present thirty-eight species that regularly 

 pass from the eastern United States to South America or Panama, 

 avoiding the West Indies. 



Certain species occur in the eastern United States and in the 

 West Indies, but are known so rarely in Yucatan and adjacent 

 parts of Central America as to make it practically certain that the 

 species as a whole passes to South America by way of the West 

 Indies. Among these are : 



Yellow-billed Cuckoo (Coccyzus americanus). 

 Chuck-will's- widow (Antrostomus carolinensis). 

 Florida Nighthawk (Chordeiles Virginia tins ckapinaui). 

 Grav Kingbird {Tyrannies dominicensis). 

 Bobolink (Dolichonyx oryzivorus). 

 Black- whiskered Vireo ( Virco calidris barbatulus). 

 Black-throated Blue Warbler {Dendroica ccerulescens) . 

 Black-poll Warbler (Dendroica striata). 

 Connecticut Warbler {Geothlypis agilis). 



To South America via the Bahamas : 

 Gray-cheeked Thrush (Hylocichla alicio?). 



In addition to the above-mentioned species there are eighteen 

 species from the eastern United States that pass in winter to South 

 America or Panama. The Mangrove Cuckoo {Coccyzus minor) is 

 resident throughout so much of its range in the West Indies, Cen- 

 tral and South America that no migration route for it can be out- 

 lined. At the present, there seem to be no data to prove or 

 indicate that the Kingfisher ( Ceryle alcyon), the Barn Swallow 

 {Hirundo erythrogastra), the Bank Swallow {Riparia riparia) and 

 the Cedar Waxwing (Ampe/is eedrorum) ever cross the Gulf of 

 Mexico. It is practically certain that some Black-billed Cuckoos 

 (Coccyzus erythrophthalmus) from the eastern United States pass
