 ornamental shrubbery in the yard, tho quite often an orchard 

 is chosen. 



563. Spizella pusilla pusilla (Wils.). Field Sparrow. 



The Field Sparrow is an abundant breeding bird 

 within our commonwealth, where its chosen haunts occur, ap- 

 parently reaching its greatest abundance in the Alleghanian 

 and Carolinian faunas and being less common in the northern 

 ties of counties which are featured by the Canadian fauna. 



567. Junco hyemalis hyemalis ( Linn . ) . Slate-colored Junco. 



Along the main ridge of the Alleghanies and in 

 those counties possessing a well defined Canadian fauna, the 

 Junco breeds regularly and in some cases abundantly. 

 Personally I have found the nests with either eg^s or young 

 of this species in the following counties, Pike, Monroe, 

 Sullivan, and Warren. In parts of Warren County, it may 

 really be called abundant. With the possible exception of 

 Erie County, it breeds regularly in all of the northern tier 

 of counties, as well as in the following, Elk, Forest, 

 Cameron, Clearfield, Lycoming, Blair, Cambria, Center, Union, 

 Sullivan, Wyoming, Lackawanna, and Luzerne. It is common 

 only in those counties where the Canadian fauna is well de- 

 fined, especially in portions of Sullivan, IflcKean, Potter,
