 County, where Mr. E. 17. Campbell has taken several nests. 

 On the Pocono plateau, I have found them regularly, tho not 

 in great numbers and have taken breeding birds; recently 

 Mr. Leibelsperger has noted them as far south as Berks 

 County, and Mr. Stone in Fulton County. 



477. Cyanocitta cristata cristata (Linn.). Blue Jay 



This beautiful marauder is one of the most general- 

 ly known of all our birds, occuring thruout the state and 

 breeding in every county. In the thickly populated section 

 about Philadelphia, it is becoming less abundant. The Blue 

 Jay appears to be most common in the section lying within 

 the Alleghanian fauna and there is one of the most character- 

 istic and abundant birds. 



486a. Corvus corax principalis Rlflgw . Northern Raven. 



Formerly this bird bred over a large portionr of 

 the mountainous country, but in later years it has become 

 extinct in a great many localities. Despite continuous 

 persecution, the Raven still breeds regularly in Center 

 County, where the author has taken several sets of eggs. 

 At the present time, the author knows of nesting pairs in 

 the following counties, Wyoming, Huntingdon, Blair , and 

 Lycoming. It undoubtedly nests also in the wilder mountain-
