 316. Zenaidura macroura carolinensis (Linn.). Mourning Dove. 



The Dove is one of the most common and generally 

 distributed birds that nest within the state . In the 

 southern counties, they frequently remain thruout the winter 

 but the majority arrive in early March, and a month later 

 have started to nest. It appears to nest within every 

 county of the state, but seems more abundant in the Alle- '. 

 ghanian fauna than elsewhere. During the breeding season, 

 they are found in pairs, but at other seasons, they seem 

 gregarious to a marked degree. 



325. Cathartes aura septentrionalis Wied. Turkey Vulture. 

 This species is distributed regularly and quite 

 commonly thru most of the sections of the state lying 

 within the Carolinian and Alleghanian faunas, and breeding 

 very rarely in the Canadian faunal zone. Thruout the 

 southern tier of counties, it breeds commonly, tho it does 

 not nest in any appreciable number in Green County (Dickey) 

 or in western Pennsylvania. In portions of Chester, 

 Delaware, York, Franklin, and Adams Counties, the Buzzard 

 is very common and seems to reach the center of abundance 

 in the Susquehanna Valley. As far north as Center County, 

 it is a regular breeder, but in eastern Pennsylvania, it 

 appears to the north of Bucks County. A number of sets 

 have been taken in Chester County by Messrs. Jackson,
