 servations covering a period of four years failed to show 

 the Northern Water Thrush breeding this locality, tho the 

 Louisiana was very common. In fact I have found it nesting 

 regularly from Center County north thru Pike, Wayne, and 

 Monroe Counties, where it nests in the same swamps with its 

 northern cousin. 



Other typical northern birds breeding in the 

 hemlock forests of the mountains are the Red Crossbill, Pine 

 Siskin, Junco, Brown Creeper, Red-breasted Nuthatch, Golden- 

 crowned Kinglet, and Olive-backed and Hermit Thrushes. 

 About Pocono Lake in Monroe County, a number of these species 

 breed along with the Nashville Warbler and the White- throated 

 Sparrow. Perhaps the most typically Canadian fauna at the 

 present time is found in Warren County, where Mr. Simpson 

 finds shch species as the Goshawk, Acadian Owl, Yellow- 

 bellied Sapsucker, Pine Siskin, Mourning, Canadian, Black- 

 throated Blue, Blackburnian, and Magnolia Warblers, North- 

 ern Water Thrush, Solitary Vireo, Brown Creeper, Olive-backed 

 Thrush, and Hermit Thrush nesting regularly. 



Remarks 

 Concerning the material presented in the present 

 thesis, the author has tried to gather practically all the 

 reliable breeding records for the various species in their 

 Pennsylvania range. A large amount of the material has 

 never before been presented to the public. Many quotations
