The British Trust for Ornithology (BTO) has put a call out for volunteers to help with this year’s bat survey in Norfolk. The Norfolk Bat Survey (www.batsurvey.org) was very successful in collecting valuable information about bats in the county in 2013. Plans this year are for the survey to be even bigger and better.
The survey uses automated bat detectors to record the presence of bats, and volunteers are needed to help put out these detectors. They are then left to run overnight and record the echolocation calls of passing bats. The resulting sound files are then analysed by special computer programs, which produce a list of the bats recorded from the site. This information is then fed back to the volunteer who operated the detector.
