Echolocation in bats was suspected as early as 1912, but it was not until 1938 when G. Pierce and D. Griffi n that provided evidence of bats emitting ultrasonic pulses using an ultrasonic detector that the concept began to gain acceptance. ... Teachers’ notes 5.

Echolocation in dolphins was suspected around 1947 as was evidenced in the personal notes of A.

The term echolocation was coined by the American zoologist Donald Griffin, whose work with Robert Galambos was the first to convincingly demonstrate its existence in bats in 1938. Early research.

However, they make the assumption that, like bird songs, echolocation calls of bats are species-specific. After each bat reached the success capture rate of 80%, we began to record its echolocation calls and flight paths. Our analysis method allowed us to assign echolocation calls to individual vocalizing bats when two individuals were paired in the same large flight room.

Bats harbor many secrets they have yet to give up.
