it appears probable that other records in the northern part of the 

 range may be of nesting birds. 



Migration. — Records of the recovery of banded barn owls show that 

 certain individuals make lengthy nights that appear to be more or less 

 seasonal. These data are more numerous from the eastern part of the 

 range and thus far the evidence pertains only to travels from breeding 

 grounds to more southern points. In practically every case the record 

 concerns a bird banded as a fledgling in its nest. For example, a 

 bird banded in New Jersey at Westville on May 20, 1925, and another 

 at Oradell on June 22, 1925, were recovered at Wilmington, N. C, 

 on November 16, 1925, and at Savannah, Ga., on January 14, 1926, 

 respectively. A third, also banded at Westville, N. J., on November 

 14, 1925, was retaken at Trappe, Md., on April 5, 1926. Two others 

 banded in New Jersey were recovered at southern points, but in both 

 cases the elapsed time was a year or more, as follows: One banded at 

 Westville on June 4, 1926, was recaptured in Jasper County, S. C, in 

 February 1928, and the other, banded at Riverton on June 13, 1929, 

 was recovered at Berea, N. C, on November 15, 1930. 



The files of the Biological Survey contain many other recovery 

 records covering the details of flights of banded barn owls, as — from 

 Wisconsin to Arkansas, from Illinois to Mississippi, from Ohio to 

 Arkansas and Alabama, and from Pennsylvania to Georgia, the dates 

 in some cases being strongly suggestive of regular seasonal migration. 

 On the other hand, there also are records of birds that obviously 

 remained in the north and were recovered in midwinter not far from 

 the point of banding. About 20 cases are available of barn owls 

 banded in California, all of which were recovered in the general vicinity 

 where they were banded. 



To sum up, it appears that in the eastern part of the country some 

 young barn owls make extensive journeys southward that have some 

 characteristics of true migration. This apparently is not general, how- 

 ever, and may be similar to the postbreeding season wanderings of 

 certain herons, gulls, and other birds. 



Casual records. — The only record of this species of British Columbia 

 is the breeding female captured at Ladners Landing, near the mouth 

 of the Fraser River, about April 7, 1909. In addition to a specimen 

 obtained at Aylesbury, Saskatchewan, on May 5, 1924, there probably 

 are one or two other sight records for that Province. There are two 

 records for Manitoba, one taken at St. Amies on November 6, 1912, 

 and another near Doleraine early in October 1927. There are several 

 records for Ontario, the details of the most northern occurrences being 

 a male taken at Toronto on September 7, 1899, and two specimens 

 reported by Young in 1900 from the vicinity of Kingston. 



A specimen was taken at Lyndon in northern Vermont on June 4, 

 1894, and there are three records for Maine, one shot at Biddeford on
