DELAWARE VALLEY OENITHOLOGICAL CLUB. 31 



throated Green fairly common at several places. These with 

 the Alder Flycatcher, Veery, Bobolink and Rose-breasted Gros- 

 beak constituted the only species that would be regarded as 

 " boreal " from the standpoint of the lower Delaware Valley and 

 they are for the most part Alleghanian rather than Canadian. 

 Such an uncommon species as the Golden-winged Warbler was 

 met with in a number of places, and the Hooded Warbler was 

 abundant. The Carolinian element even at the higher eleva- 

 tions was marked and we were surprised to find such species as 

 the Chat, the Blue-wing and Worm-eating Warblers, and the 

 Louisiana Water Thrush, Especially interesting was a colony 

 of hundreds of Short-billed Marsh Wrens nesting in the Wallkill 

 Valley lowlands, where Mr. Rhoads also found a marked Caro- 

 linian element.
