Bats Give Off 'Jamming' Call to Prevent Others from Feeding (8 of 10) (VIDEO)

American Association for the Advancement of Science (AAAS)

Caption

A Mexican free-tailed bat echolocates and captures a tethered insect in the field. Echolocation calls speed up as the bat nears the prey, allowing the bat to rapidly update its 'sonar screen' before capture. Audio and video are slowed 20 times. This material relates to a paper that appeared in the Nov. 7, 2014 issue of Science, published by AAAS. The paper, by A.J. Corcoran at Wake Forest University in Winston Salem, NC, and colleagues was titled, 'Bats jamming bats: Food competition through sonar interference.'
