 lakes in Pike County. In June 1910, I met with a pair of 

 these "birds that were undoubtedly breeding near Foxburg, 

 Clarion County. Practically all of my correspondents fail 

 to mention it as a breeder. 



365. Aluco pratincola ( Bonap . ) . Barn Owl. 



The Barn or Monkey-faced Owl is one of the few 

 birds that seem able to withstand the advances of cilivi- 

 zation. Where twenty years ago, the Barn Owl was regarded 

 as a scarce bird, it has now grown quite common, especially 

 thruout Chester, Montgomery, Delaware, York, and Cumberland 

 Counties. It breeds regularly and commonly in many localities 

 within the Carolinian fauna, with the exception of south- 

 western Pennsylvania, where Mr. Dickey finds them unknown 

 at present as breeders in Green County, tho it has been 

 found rarely nesting in Allegheny, Payette, and Beaver 

 Counties. It seems to be pushing farther back into the 

 Alleghanian Life zone, for it has recently been found 

 breeding by Mr. Leibelsperger near Fleetwood, Berks County. 

 At present I have definite knowledge of the Barn Owl's 

 nesting in the following cbunties: Alleghany, Beaver, 

 Berks, Cumberland, Chester, Dauphin, Delaware, Fayette, 

 Lancaster, Franklin, Adams, Montgomery, Bucks, Philadelphia, 

 Lebanon, and York.
