The first two, presumed to be young in their first year of life, were each recov- ered in the year of banding. Lincoln (1939: 128) listed a Long-eared Owl of unknown age banded at Escon- dido, California, 22 April 1934, and shot at Corbeil, Ontario, 9 October 1934, a distance of 3135 km north- east. Considering banding of all species, Lincoln com- mented 'This is one of the most unusual records thus far ; Lincoln also listed a juvenile Long-eared Owl that had traveled northeast from St. John, Michi- gan, to Abitibi, Quebec, between 14 May and 4 Sep- tember 1933, a distance of 845 km. In each of these instances it is not known whether the northward move- ment was achieved in the first or second year of life, nor whether either represents migratory movement or dispersal to a very different breeding location. Four distant recoveries during or immediately after the breeding season might have been construed as evi- dence in favor of nomadism, had they not been banded during migration. Two were adults banded as April migrants at Brad- dock Bay, New York; one flew 465 km to the west to Michigan in mid-April of the subsequent year and the other was found dead 645 km northwest in Ontario on 5 July, 10 years after it had been netted as an SY bird by subpermittee Frank Nicoletti (see below under Longevity). Two others, banded as late migrants at Whitefish Point, Michigan (on 22 April and 14 May), were recovered two years later; one went northeast 480 km and was shot in mid-June in western Quebec; the other
