nets throughout the night. Mist nets were collapsed shortly before 

 dawn. An observer also used one or more bat detectors at the 

 entrance, beginning at dusk and staying at least an hour, and then 

 until there was no bat activity for more than 30 minutes. 



Habitat Use Surveys 



Once a site was selected, from two to five mist nets were set up in 

 the evening across trails, next to laJceshores, and across streams or 

 ponds (Kunz and Kurta 1988). Nets were not raised into final 

 position until about one-half hour after sunset to avoid catching 

 birds. Depending on the site, the height of the bottom of the net 

 above ground or water varied from less than a foot to 6 feet. Nets 

 were checked at least every hour until after midnight, then again 

 between one hour, and one-half hour before sunrise. Nets were taken 

 down one-half hour before sunrise to avoid catching birds. 



One or two walking transects were conducted at each site, depending 

 upon available personnel. Beginning approximately one-half hour 

 after sunset, and lasting for one hour, a transect was walked through 

 habitat representative of the area, using one of the bat detectors. 

 All bats heard were recorded as "cruising, searching, or feeding, " 

 depending on activity, by species if identifiable, and by time 

 period. 



A few transects were run during the middle of the night (between 1 AM
