THE OWLS. 



Great Homed Owl {Bubo virginianus). 



Barred Owl {Syrnium nebulosum). 



Barn Owl (Strix pratincola). 



Screech Uwl {Megascops asio). 



Long-eared Owl {Asio ivilsonianus)- 



Saw-whet Owl {Nyctala acadica). 



Short-eared Owl {Asio accipitrinus). 



Snowy Owl {Nyctea nyctea). 



Great Gray Owl {Scotiaptex cinerea). 



American Hawk Owl {Surnia ulula caparoch). 



Of this list of owls the six species lirst named in the 

 preceding column are common residents (i. e., are found 

 during all months of the year) in Pennsylvania. Audu- 

 bon once found the Short-eared Owl nesting in this 

 State, and, probably, the species may still breed in 

 some secluded situations within the Keystone bounda- 

 ries. The three remaining species of this owl-group 

 come to us at irregular intervals in winter time from 

 the dreary, cold and banen boreal wilds. 



Few, if any. of the common and native birds are 

 better known to people in general than are certain of 

 these birds of prey, some of which are rather common 

 at all times or during some period of the year, in almost 

 evei-y section of the State, 



These raptoi-ial birds are, with the few exceptions 

 previously noted, serviceable rather than detrimental 

 and their presence about our farm land should be 

 encouraged. There is unquestionably a strong preju- 

 dice in the luinds of many citizens of both the city 

 and coimtiv districts aginst not onlv hawks and owls.
