Our project involves a combination of capture survey methods, as well as acoustic survey techniques. For the capture work, mist-nets will be deployed at sunset are taken down sometime between 10 pm and 1 am, depending on bat activity. For each bat, we will collect oral and guano samples. We will hold bats in clean cloth bags for up to two hours to collect these samples. Oral swab samples will be collected through gentle agitation of the mouth with a fine swab. Guano samples will be collected from the cloth bags and bags will be checked every 15 mins. Bats will be released at point of capture as soon as guano pellets are naturally voided into the bag and oral samples are collected. Echolocation calls of the bats may be recorded as they are released to be used as voucher calls for the development of species auto-classification software. The acoustic sampling involves deploying bat detectors for between four and seven consecutive nights. Survey locations are accessed at the beginning and end of the survey period to deploy and retrieve the detector but otherwise do not need maintenance or attendance. Detectors are elevated off the ground using a painter’s pole or similar to ensure quality recordings. The poles are stabilized using guy lines tied off to tent stakes, rocks, fence posts, etc. The technique is non-invasive and there is no sign of their presence after the equipment is retrieved. The detectors emit no sound or light and record only at night.
