21 Jan 2018 Recording Bats
I’ve always been intrigued about bats flying around at twilight and catching insects. We see them every evening on our fishing trips to lakes in Northern California. On one trip I decided to see if I could film them with the help of night vision and a bat detector.
A bat detector is basically a microphone and speaker that takes the high frequency sound of bats and translates it so that we can hear the sound. The unit that I got is called a Belfry Bat Detector and it works quite well.
