Abstract
Migrating Northern Saw-whet Owls were captured and banded at a site in the Virginia Piedmont in the fall of 2005, and the results were compared with the results of banding from the previous three years. The results were also compared to similar efforts to monitor migration that were made on the coastal plains and the mountain regions of Virginia in these same years. Migration volume was higher in the mountains compared to the piedmont and coast, and the mountains experienced the earliest migration peak, followed by the piedmont, and then the coastal plain. There was not a significant difference between adult and immature Northern Saw-whet Owls in their migration timing. Adults made up the bulk of migrating owls in the mountains and on the piedmont, which is consistent with these years being non-invasion years. The coastal site, however, had a nearly even ratio of adults to immatures, which may reflect a geographic variation in migratory route in these two age classes.
