🔥 Spectrogram of 3 common pipistrelles (45-50khz) and 2 serotine bats (20-25kh) (and a noctula, 15-20khz). When individuals of the same species of bats forage in close proximity, they slightly change their pitch to avoid confusion https://i.imgur.com/dg6kF9Q.jpeg https://redd.it/1ovzec0 @NatureIsLit
