 18, 1907, took the first set of eggs of this species record- 

 ed from Pennsylvania. The nest was built well out in a 

 sphagnum swamp, sunken flush with the surface in the side 

 of a hummock of sphagnum. It was rather fairly built of 

 leaves, moss, and grass, lined almost entirely with fine 

 dead grass. The eggs were only two in number, the set being 

 incomplete. Two days later, on June 20, Mr. W. L. Baily 

 found a second nest of this bird, holding a complete set 

 of four eggs, the nest being sunken flush with the surface 

 of the ground . 



648a Compsothlypis amerlcana usneae Brewst. Northern Parula 

 Warbler. 



The northern form of the Parula Warbler breeds 

 regularly thruout the majority of the counties embraced in 

 the Canadian fauna. In Monroe, Pike, Sullivan, Center, 

 Hundington, Clarion, and Warren Counties, I have found the 

 Parula occuring regularly during the summer months, while 

 other observers report it from various points along the 

 Alleghanies and the northern tier of counties. It also 

 occurs sparingly in the Alleghanian fauna, and Mr. Stone has 

 found it nesting in the Carolinian fauna of the lower 

 Susquehanna Valley, while Harry G. Parker took one nest in 

 Delaware County (0. and 0. 1886).
