available. Actual arrival and departure dates are apparently influ- 

 enced as much by weather conditions and available food as by response 

 to the migratory impulse. 



Early dates of spring arrival north of the regular winter range are: 

 Vermont — Rutland, March 3. Quebec — Montreal, April 17. New 

 Brunswick — Scotch Lake, April 12. North Dakota — Rice Lake, 

 April 9; Wahpeton, April 13. Manitoba — Treesbank, March 28; 

 Margaret, April 1; Aweme, April 4. Saskatchewan — Indian Head, 

 April 13; Osier, April 18. 



Fall migration. — Late dates of fall departure from the regions north 

 of the regular winter range, are: Saskatchewan — Indian Head, Octo- 

 ber 20. Manitoba — Margaret, October 20; Aweme, October 31; 

 Treesbank, November 2. North Dakota — Argusville, November 18; 

 Marstonmoor, November 18. Ontario — Ottawa, November 1. Nova 

 Scotia — Halifax, October 1. Quebec — Montreal, October 22. Ver- 

 mont — Rutland, October 24. 



Data are too few to throw much light upon the times of arrival and 

 departure in regions south of the breeding range, but in general these 

 owls may be expected in such areas during the latter part of November 

 and December and they will remain until late February and March. 



The extent of the travels that may be made by long-eared owls is 

 graphically illustrated by the flights of two individuals marked with 

 numbered bands. One of these, banded at Rosebud, Alberta, on July 



4, 1933, was shot at Layton, Utah, on February 2, 1935. The other, 

 banded at Escondido, Calif., on April 22, 1934, was recaptured at 

 Corbeil, Ontario, on October 9, 1934. This last record is one of the 

 most remarkable banding records thus far obtained. It has, however, 

 been thoroughly checked for accuracy. 



Casual records. — A specimen was taken on the Taku River, Alaska, 

 on September 26, 1909; three were collected in May 1877 or 1878 at 

 Godbout, Quebec; and according to Preble (1902), it was found at 

 Fort Severn, Manitoba, by Hutchins. One was seen at Oakley Depot, 



5. C, on January 16, 1917, while Wayne (1910) refers to two speci- 

 mens collected in this State at Mount Pleasant, on March 16, 1896, 

 and another at the same place on January 16, 1906. He refers also 

 to another taken in Edgefield County, S. C, during the winter of 

 1905. Three were seen and one was collected on San Clemente Island, 

 Calif., in December 1908.
