Yesterday, I spent an hour listening for bat echolocations, as well as watching them around the Conservatory Water, aka the Model Boat Pond. Bats are migrating through the city, and with it getting dark earlier, I don't have to stay out too late! So the next few weeks are perfect to go bat watching.
Using the Wildlife Acoustics Echo Meter Touch 2 Pro Bat Detector and iOS software, I was able to capture a large number of echolocations. The software does its best to identify which species of bat it hears, sort of like a Shazam for bats. The software can make mistakes, so my results could have errors. While I recorded a great number of bat passes, a single bat could have created many of them.
