Abstract.—Few studies have investigated autumn migration of the northern long-eared myotis (Myotis septentrionalis). We conducted a two-year radio-tracking study of M. septentrionalis in southeastern Nebraska to document migration dates, activity in autumn, and movements to wintering sites. We found evidence that M. septentrionalis are migrating as late as October and early November. Prior to migration, cold nights curtail flying times of M. septentrionalis. Two bats in this study did not emerge from their roost trees for seven consecutive nights during a period of colder weather. We monitored one bat leaving our research area on the night of …
