OF EASTERN PENNSYLVANIA. nol 



believe that a more thorough exploration of the eastern 

 counties of Pennsylvania, especially in the mountainous 

 districts where dense forest vegetation abounds, isolated 

 pairs may stop from their northward journey, to breed. 

 The presence of young birds in the beginning of Au- 

 gust, would seem to argue in favor of this supposition. 

 It may be that a few depart 'from their breeding-quarters so 

 early, but then this does not seem altogether likelv when 

 it is borne in mind that scarcitv of food determines in a 

 great measure the autumnal migration. Then, again, these 

 Pigeons do not generally move in small flocks. 



The eggs of this species are never more than two in num- 

 ber. They are oval in contour, and equally rounded at both 

 extremities. Their color is a pure white, and average 

 measurement i .42 by 1.04 inches. They vary considerably. 

 not only in length, but also in width ; notable differences 

 being observed in the same nest-complement. 



Zensedura carolinensis, 



The Carolina or Common Dove is pretty generally 

 distributed throughout the United States. It ranges from 

 the Atlantic to the Pacific coast, and from the Gulf of 

 Mexico to Canada. In the southern part of Maine, and as tar 

 east as Calais, it is found ; but it was not taken by Mr. Yer- 

 rill, at Norway, nor has it been observed in the northern 

 counties. In Western Massachusetts, where once quite 

 plentiful, it is now very shy and rare. Mr. Allen frequently 

 met it in both Colorado and Kansas. Mr. Clark found 

 it nesting around the luxuriant growth of the Opuntia. 

 near Ringgold Barracks, in Texas ; and Lieut. Couch met 

 it in large numbers from the Rio Grande to beyond 

 the Sierra Madre. Dr. Newberrv found it in the different 

 parts of Oregon and California which he visited. It lias 

 also been noticed to be very common throughout Washing- 

 ton Territory. In New Mexico : near San Antonio. Texas : 

 and along the Gulf coast, it was met with by Dr. Kennerly.
