Summary

Female big free-tailed bats Nyctinomops macrotis have been captured over water in northern Arizona in high elevation (> 2,400 m) forests and low elevation (1,500 m) desert scrub vegetation. We hypothesized that roost sites were in vertical walls of cliffs that were up to 25 km away from capture sites given the flight capability of these bats. During summer 2005 we captured eight females over ponds and attached radio transmitters to locate day roosts. We also identified locations used during nightly movements from 1 to 6 nights of radio tracking. We found three day roosts for seven bats; average distance (� SE) from a capture site to a roost was 12.1 � 3.0 km. Roosts were small maternity colonies used by ? four N. macrotis in cracks [...]
