Potential of Echolocation for Communication
summary
Claims that echolocation doubles as communication rest on concrete recordings and tests: GPS + on-bat microphones track dozens of individuals, a sensory-motor agent model reproduces collision-free emergence despite heavy jamming, and focal bats emit 50 times per second providing redundancy that the model shows is sufficient. Playbacks into a 3D-printed bat ear prove social calls produce echoes; pup vocal ontogeny is tracked from day 0 to months and ML clusters identify emitter/context but behavioral habituation gives ambiguous responses. Plants emit ultrasound around 50–60 kHz and moth playback trials produce a repeatable but puzzling egg‑laying bias.
