12 PROCEEDINGS OF THE 



ago by Mr. Pierce, of Renovo, who still has the eggs in his col- 

 lection. For this information I am indebted to Mr. W. E. 

 Clyde Todd, of the Carnegie Museum, Pittsburg. 



Aside from actual records of nesting, the Northern Raven 

 seems to have been observed with more or less regularity, even 

 during the twenty years of the Delaware Valley Ornithological 

 Club's existence, and evidence of its probable breeding in Ful- 

 ton County was obtained by several members. Dr. Warren's 

 "Birds of Pennsylvania" includes records of its occurrence 

 in a number of counties, and although he gave no definite 

 nesting records, it seems safe to say that up to 1890 at least it 

 bred locally through the wilder mountainous regions of the 

 State. 



Mr. R. B. Simpson, of Warren, Pa. , writes me that the Raven 

 was formerly of regular occurrence there, as well as in Forest 

 County, but that it had disappeared some years back, and he 

 had not observed it until last year, when several were seen 

 about Renovo. This is an especially valuable bit of informa- 

 tion, as Mr. Simpson is one of the most careful ornithologists 

 in the State, and he could hardly have failed to observe Ravens 

 had they been constantly resident in his locality. Besides the 

 above notes I have recent records of the occurrence of Ravens 

 in Somerset, McKean, Clearfield and Huntingdon counties. 

 Farther to the east I have reports of their occurrence at rare 

 intervals in Wayne and Pike counties, and casting out my pre- 

 vious record as doubtful (Cassinia, 1905), I have a positive 

 record of their occurrence in southwestern Pike county, as I 

 observed two specimens there at close range on August 12, 1909. 

 Mr. Stone also saw one in Sullivan county in the same month. 



My experience of the last two years would tend to show that 

 though rare and extremely local, yet the Raven is still a regular 

 resident among the mountains of Center County. Moreover, it 

 is extremely tenacious of its nesting place, as will be shown by 

 the evidence of my notes. The fact of its rarity is manifest 

 when I say that I had been at State College for over eight 

 months before I saw my first Raven, and this despite the fact 

 that I was in the field twice a week and kept a sharp lookout 

 for them.
