 boundaries during the last ten years. Mr. Prank S. Burns, 

 in his wonderful monograph of this species, gives the best 

 possible resume of its breeding habit3 in Pennsylvania, and 

 Mr. R. P. Sharpless in Cassinia (1909) also gives a very 

 good account of its status in Pennsylvania. To the best of 

 my knowledge, sets have been taken in the following 

 counties: Pike (Rath), Monroe, Northampton (both for 

 Borris), Berks (Leibelsperger) , Bucks (several), Montgom- 

 ery (several), Delaware (several), Chester (several), 

 Renova (Pierce), Green (Jacobs), Hundlngton (Harlow), 

 Center (Harlow), and Warren (Simpson). It probably breeds 

 sparingly in nearly every county of the state but seems 

 less common in the northern sections embraced by the Canad- 

 ian fauna and is unknown as a breeder close to Pittsburg, 

 tho I have found it nesting near Poxburg, Clarion County.

 Eagle. 



The Bald Ea^le, tho much more rare than formerly, 

 still occurs in Pennsylvania at all seasons of the year 

 and is still a regular breeder at several places within 

 our commonwealth. At present to the best of ray knowledge, 

 pairs are known to breed in the following counties: Lan- 

 caster, Wayne, and Erie, as well as in a few scattered 

 localities thruout the Pennsylvania mountains. A pair or 

 two undoubtedly nest either along the upper Delaware or on
