“On the 20th June 2019, I went out to do a little informal bat survey of the Centenary Field. The aim of this was to give our ecologists an idea of the species that are present before they wrote up their biodiversity management plan (watch this space for updates on the plan!).
Despite only surveying for 40 minutes, I encountered at least three or four species of bat using my Magenta bat detector!
The bat detector turns the high frequency bat calls, which are undetectable to human ears, into lower frequencies that we can hear.
The species noted included soprano pipistrelle (Pipistrellus pygmaeus), common pipistrelle (Pipistrellus pipistrellus) and a noctule (Nyctalus noctula).”
