 366. Asio wilsonianus (Less.). Long-eared Owl. 



This nocturnal, medium-sized, Owl, altho a fairly 

 common winter resident, seems to be decidedly rare and local 

 as a breeder, and thruout the greater portion of the state, 

 does not seem to nest. Dr. Warren, in his "Birds of Pennsy- 

 lvania", mentions having found several nests in Chester 

 County and also records a nest found by Audubon on the 

 Juniata River. Mr. Ifitraer Stone (Birds of Eastern Pennsyl- 

 vania and New Jersey) also mentions a nest found near 

 Valley Forge, Montgomery County, by Dr. W. E. Hughes. 

 Mr. Richard P. Miller writes me that on June 9, 1899, he 

 discovered four fledglings of the Long-oared Owl, but the 

 bird is now probably extinct as a nester in this county. 

 Most of the Pennsylvania sets of Long-eared Owl seem to have 

 come from Chester and Montgomery Counties. Mr. Thos. H. 

 Jackson writes me that he took a set of five half- irtcuba ted 

 eggs near West Chester on April 15, 1870, and nest with five 

 fresh eggs on April 1, 1902, while Mr. C. J. Pennock took 

 a nest near Kennett Square on . In Mont- 



gomery County, Messrs. Thos. H. Gill in, and G. B. Benners 

 have taken several sets near North Wales between the dates 

 of April 17 and May 2, while the author has observed the 

 birds near Edge Hill, thruout the year. Prom the western 

 and mountain regions, I have no authentic breeding record, 

 tho it probably breeds sporadically and rarely thruout the 

 XXXXK entire state.
