89. Asio wilsonianus Long-eared Owl, "cedar 

 owl," "hoot owl," "little horned owl," "mouse owl." 

 Rather rare resident, common and gregarious in 

 winter. Jackson has personally found four nests in 

 Willistown, West Goshen and Pocopson townships; 

 the first with five eggs, Apr. 15, 1870 (Orn. and 

 Ool., xi, 1 88). Pennock found a nest with eggs, 

 Kennett Square, Apr. 7, 1906; Hughes found nests 

 at Paoli and Valley Forge, and I have found it nest- 

 ing in the Paoli barrens, 1916 and 1917. 



90. Asio flammeus Shcrt-eared Owl, "day owl," 

 "marsh owl." Tolerable common winter resident. 

 This species will flush in grass fields and have been 

 shot in the fall by hunters. Josiah Hoopes reported 

 colonies in his nurseries at West Chester, about 

 1866, and 1890-1891 (Stone, Bd. E. Pa. and N. J.,

 sources within the county: 



Arrival Oct. 27 (1889) Dec. 8 (1886); ave. 

 8 yrs., Nov. 18. 



Departure Mar. 5 (1887) Apr. 18 (1888); 

 ave. 7 yrs., Mar. 22. 



91. Strix varia varia Barred Owl, "hen owl," 

 "hoot owl," "rain owl." Rare winter resident ac- 

 cording to available data, though Michener and 

 Pennock intimates that it is a resident. Robert 

 P. Sharpies mentions one killed recently that he be- 

 lieved nested in an old tree in the Bower's paper 

 mill woods near West Chester, and Harry Wilson
