Bats sabotage rivals’ senses with sound in food race 蝙蝠靠聲音干擾食物競爭者的感覺
This is the first time scientists have witnessed this behaviour in one species - the Mexican free-tailed bat.
When bats swoop in darkness to catch prey, they emit high-pitched sound waves - a process called echolocation - which speeds up as they get closer to their target. This well-known skill is vital for them to hunt for food and to navigate their environment.
Lead author of the work, Aaron Corcoran from Wake Forest University in North Carolina, was initially studying moths when he heard these bat calls.
"One bat was trying to capture an insect using its echolocation. The second bat was making another sound that looked to me like it might be trying to jam or disrupt the echolocation of the other bat," said Dr Corcoran.
