dent, April 5 to October 1 (earliest February 10, 1904); common migrant; 

 breeds (May 18, 1892). 



136. Pandion haliaetus carolinensis. American Osprey. — Regular 

 migrant, fairly common May (May 10, 1902), and September 1 to 15, and 

 probably later. 



137. Strix pratincola. American Barn Owl. — One record, a male 

 taken September 7, 1899. 1 



138. Asio wilsonianus. American Long-eared Owl. — Common 

 fall migrant, October 2 to November 7; rare summer resident; breeds 

 (May 24, 1894). 



139. Asio accipitrinus. Short-eared Owl. — Regular migrant, 

 March 5 to 15, and probably through April; abundant in the fall, October 

 3 to December 26, when large flocks sometimes occur. A light phase of 

 plumage occurs very rarely. 



140. Syrnium varium. Barred Owl. — Regular winter resident, 

 October 10 to March 19; sometimes abundant (October 1-10, 1902). 



141. Scotiaptex nebulosa. Great Gray Owl. — Winter migrant 

 of irregular occurrence. The great flight that took place in the winter of 

 1889-90 is recorded by Mr. Wm. Cross. "I have received twenty-three 

 specimens, and have had them reported from various parts of the Province. 

 One of my acquaintances stationed at Barrie, received twenty-six this 

 season. They began to come into this region in November, and increased 

 in numbers up to February, after which they became very scarce again." 2 

 This is the largest flight recorded, but specimens have been taken in 

 December, 1890, January, 1894, January and March, 1895, and January 

 and February, 1896; the visits appear to have ceased after this. 



142. Cryptoglaux tengmalmi richardscni. Richardson's Owl. — 

 Winter migrant, of irregular occurrence, November 8 to April 3; I have 

 examined nine specimens since 1885, but the number taken probably 

 averages one a year. 



143. Cryptoglaux acadica. Saw-whet Owl. — Regular winter resi- 

 dent, October 4 to March 3; probably resident, as I have a young bird 

 taken May 15, 1889, and another young one taken in August. A large 

 flight of these owls occurred in the fall of 1889, and in October (12 to 28), 

 1895. 



144. Otus asio. Screech Owl. — Resident, not uncommon, some- 

 times abundant in October and November; breeds (April 27, 1890, five 

 eggs, J. Jackson). The red phase of plumage is rare, usually occurring 

 for several years in succession and then disappearing. 



145. Bubo virginianus. Great Horned Owl. — Winter resident, 

 October 10 to March 30, usually common; a rare summer resident, a nest 

 was taken in Vaughan Township March 25, 1889, and one at Scarboro, 

 April 2, 1897.
