 176. Nyctala acadica (Gmel.). Saw-whet Owl. 



Breeding Range— Northern U. S. and British America. 

 Winter Distribution — Southward to Middle States. 



Rare winter visitant, tliough some probably occur every year. The 

 following recent captures have come under our notice, and others 

 have been reported by taxidermists : 



Germantown, Pa., Feb. 21, 1887, W. Stone. 

 Haverford, Pa., Nov. 20, 1892, W. L. Baily. 

 Philadelphia, Pa.. Nov. 5, 1892, M. L. C. Wilde. 

 Chester Co., Pa., Aug. 30, 1879, Dr. B. H. Warren. 



" " Nov. 10, 1883, " " (2). 



«' " Sept. 20,1884, " " 



Mr. W. E. D. Scott also records a large colony in a cedar grove 

 near Princeton, N. J., in winter, 1878-9 {B. N. 0. C, 1879). 



This species seems to breed regularly in the mountainous parts of 

 Pennsylvania, as a nest taken at Nazareth, Pa., April 25, 1867, 

 by Richard Christ, is carefully described in Samuel's " Our Northern 

 and Eastern Birds," and Dr. Warren records it as a regular breeder 

 at Lopez, Sullivan county, Pa., on the authority of Mr. Otto Behr. 

 Dr. J. W. Detwiler has also found it at all seasons near Bethlehem, 

 though he has never discovered the nest, and Mr. W. L. Baily se- 

 cured a specimen in the first plumage at Rasselas, Elk Co., Pa., 

 June 30, 1894. 



177. Megascoxfs asio (Linn.). Screech Owl. 



Breeding Range — Eastern N. A., British Provinces to upper S. Atlantic 



and Gulf States. 

 Winter Distribution — The same. 



Abundant resident, breeding throughout. 



The red phase of plumage seems to be the more common in the 

 vicinity of Philadelphia. 



178. Bubo virginiamis (Gmel.). Great Horned Owl.

 Winter Distribution — The same. 



Resident. Rather common in the wilder parts of the country, but
