Foraging activity 



Bats were regularly encountered foraging over roads, creeks, and 

 ponds in the study area (Table 5) . A total of 1,031 bat passes 

 were detected during two surveys at each of the transect sites. 

 Of these, 196 passes contained a feeding buzz (19 percent) . 

 Foraging activity was highest at Camp 32 where 43 percent of bats 

 encountered were attempting to capture prey. No foraging bats 

 were encountered at three sites - Ross Creek Cedars, upper Beaver 

 Creek along road 152, and at the clearcut by road 427.
