 portion of the state, the Bob-white is now a scarce bird. 

 The center of abundance of the Bob-white seems to be along 

 the southern tier of counties, especially from York to 

 Greene Counties. In sections of Dauphin County I have found 

 it quite common, while in Greene County it is very common, 

 according to my friend Mr. S. S. Dickey. In Center County, 

 however, it is quite rare, and about Warren, Mr. R. B. 

 Simpson has found it breeding on but one occasion.

The Ruffed Grouse or Pheasant is still quite 

 common as a breeder thruout the mountainous, thinly populated 

 districts of Pennsylvania, as central and northern tier 

 of counties, elsewhere rare. With the exception of a 

 few counties in the southeastern part of the state (Delaware 

 and Philadelphia) and in the vicinity of Pittsburg in the 

 southwestern portion, the Grouse still breeds in prac- 

 tically every county of the state. It is generally less 

 common than heretofore. In sections of Pike, Wayne, 

 Monroe, Warren, Center, and Huntingdon Counties, I have 

 found the Grouse to be abundant in favorable localities. 

 Mr. S. S. Dickey finds them fairly common in Greene 

 County, and along the southern tier they occur regularly 

 in Somerset, Bedford, Fulton, Adams, and Franklin Counties, 

 but not so abundantly as farther north.
