Ripple Effect Used By Bats When Hunting Frogs During Mating Season
2014-01-24 12:56:12

Brett Smith for redOrbit.com - Your Universe Online As male túngara frogs call from their puddles to attract females, they create ripples that spread across the water. According to researchers at the Smithsonian Tropical Research Institute (STRI) in Panama, these ripples are used by other male frogs to assess their competition – and also by bats looking for their next meal. If it sees a bat flying overhead, a male túngara will stop calling – yet ripples continue moving for several...

Bats Rely On Vision To Navigate, Echolocation To Catch Insects: Study
2013-12-13 07:34:50

April Flowers for redOrbit.com - Your Universe Online\ Bats rule the night skies, using the power of echolocation, or reflected sound. More than 1,000 species of echolocating bats exist, compared to just 80 species of nocturnal non-echolocating birds. It seems that normal vision works in tandem with echolocation to give bats an evolutionary edge, however, no one knows exactly how. A new study, led by Arjan Boonman and Yossi Yovel of Tel Aviv University's Department of Zoology, suggests...

Previously, scientists believed the nectar-feeding bat ate insects in passing, but the latest research shows it targets its moving prey with stealthy precision. The team proved for the first time that the Pallas long-tongued bat uses a stealthier form of echolocation. Echolocation is a physical trait that involves the...
