Bats keep chit-chat simple in the air


Bat conversations might be light on substance, according to researchers from the University of Cincinnati.

Echoes received by bats are so simple that a sound file of their calls can be compressed 90% without losing much information, according to a study published in the journal PLOS Computational Biology.

The study demonstrates how bats have evolved to rely on redundancy in their navigational “language” to help them stay oriented in their complex three-dimensional world. MORE
