SOME OTHER BIRDS. 



KAVEXS, CROWS, JAYS AND SHIilKKS. 



P^ive species of tlie family CORV^IDAE are foiiiid in 

 Pennavlvaiiia, ami of these the Gommou Crow and 

 I>lue Jay are by far the best known. Indeed, proba- 

 bly no two representatives of onr bird-fauna are more 

 familiar to persons who are at all acquainted with 

 rural life than are the gaudy, garrulous Blue Jay, and 

 his suspicious, pilfei'ing relative, the Common Crow. 



THK IJAVRN. 



The northern Raven is a sub-species, that was first 

 recognized and described by my friend. Prof. Robert 

 Ridgway, the eminent Ornithologist of the Smith- 

 sonian Institute, Washington, D C. This bird pos- 

 sesses peculiarities which entitle it to be particular- 

 ized by the technical specific principalis to distinguish 

 the new form from that of its near kin the Common 

 Raven, {Corvus corax), of the older authorities. 

 It ranges from "Greenland to Alaska, soutli to British 

 Columbia, Canada, New Brunswick" and Pennsylvania. 

 In this State it is found as a resident in a number of 

 counties, particularly such as are mountainous and 

 which contain large areas of sparsely s<>ttled and ex- 

 tensivelv forested lands.
