In autumn we find these birds in old fields along the edges of 

 woods and thickets, especially in thick growths of rag weed; when ap- 

 proached they fly up into trees and bushes and remain until the in- 

 truder has passed l)y when they return to their feast. They are ex- 

 traordinarily fat at this season. 



In spring the Connecticut Warbler is almost unknown east of the 

 Alleghanies; one of the very few specimens taken at this season, 

 however, was obtained in New Jersey, by Mr. S, N. Rhoads, at Had- 

 donfield. May 20th, 1882 (Collection W. Stone) .^
