The Warblers of Central New York* 



By A. A. ALLEN, Ph.D., Assistant Professor of Ornithology, Cornell University 

 With Photographs by the Author 



THERE are thirty-nine species of 

 Warblers that breed in eastern 

 North America, Of course, one 

 could not expect to find all that number 

 nesting in one place for some are charac- 

 teristic of the south and others of the 

 north. The largest number are found in 

 the intermediate regions, and are about 

 equally divided between the Canadian 

 and Transition life-zones. Here, in cen- 

 tral New York, we are located in the 

 Transition Zone, but a few of the typi- 

 cally Austral Warblers work their way 

 this far north and a number of Cana- 

 dian species remain this far south on 

 the tops of the higher hills and in the 

 deeper ravines. Within the Cayuga 

 Lake basin we have found the nests of 

 twenty-two species, though in the case 

 of one of these, the Prothonotary, the 

 nest was built entirely by the male bird 

 and never occupied, since no female ever 

 appeared. 



The commonest and most typical 

 species, in the order of their abundance, 

 are the Yellow, Redstart, Northern 

 Yellow - throat, Ovenbird, Chestnut- 

 sided, Black and White, and Black-
