Summer Acoustic Monitoring of Bats at the Cibolo Preserve

Acoustic bat monitors were placed near stream, in prairie, in oak savannahs, and along edge sites in the Cibolo Preserve from May to August, 2017. During the 16 week sampling period, 185 gigabytes of acoustic calls were recorded representing 156,021 calls. A total of seven bat species were identified and each species was detected in each of the four habitats. Mexican free-tailed bats making up the majority of the activity. Bat activity was not different (P > 0.05) among habitat types. Bat activity was significantly different (P = 0.004) in May compared to the other months. There was moderate correlation (R2 = 0.59) between temperature and bat activity.
