Il6 SYLVICOLID^E : AMERICAN WARBLERS. 



England, being chiefly characteristic of the Carolinian 

 Fauna, though extending commonly into Massachu- 

 setts. It is rather more numerous there, and in Con- 

 necticut, than the last-named, but is still one of the 

 rarer Warblers. Entering New England in May, it 

 breeds, and retires in September. The nest, like that 

 of other species of the same genus, is placed on the 

 ground, generally in low swampy woodland. Mr. 

 Hiram Cutting informs me that he has found it in 

 Vermont. 



The best account of the nidification has been given 

 by Mr. J. Warren (Bull. Nuttall Club, i, Apr., 1876, 

 p. 6). Speaking of its breeding in eastern Massachu- 

 setts, this writer mentions a nest 

 found in Newton, on a strip of 

 swampy land on the skirts of a 

 small wood, raised about two 

 inches from the wet ground, and 

 concealed by the leaves of a

strips of grape-vine bark, lined with fine threads of 

 the same substance interwoven with a few bits of 

 grass on the whole resembling a Maryland Yellow- 

 throat's. Another nest, also found in Newton, was 

 placed in a tussock of grass in an old cart-road ; 

 it contained 4 fresh eggs on the 5th of June, and 

 was a little narrower and deeper than the one just 

 described. This was found by Mr. Towne. A third 

 nest, discovered in the same locality by Mr. Eager, 

 was like the others in structure and position, and also 

 contained 4 eggs, June 9, 1875. A nest discovered
