How the barbastelle bat has learnt to outwit its prey

The barbastelle bat has found a new way to sneak up on unsuspecting moths - by gradually emitting fainter calls as they approach. In an evolutionary bid to outsmart the bat, some moths had developed ears to detect echolocating bats and avoid being caught. But new research by ecologists at the Max Planck Institute for Ornithology in Germany has found that upon detecting a nocturnal moth, this intriguing bat species can reduce its call intensity even further while closing in on its prey. The barbastelle bat - with its characteristic bumpy face - is a very successful hunter that manages to almost exclusively feed on eared moths. Stealth fighter Comparable with stealth fighter jets, barbastelle bats use a 'stealth echolocation' tactic - echolocation at intensities that are inaudible to distant moths - to ambush prey. Their calls are more than 10 times quieter than those of oth...
