There are certain skills that once acquired, such as riding a bike or looking both ways before crossing a street, rarely have to be relearned. Most studies on learning and long-term memory in the wild focus on a handful of animal species. Now, in a paper published in Current Biology, U.S. National Science Foundation–supported researchers at the Smithsonian Tropical Research Institute share the first report of long-term memory in frog-eating bats (Trachops cirrhosis).

"Frog-eating bats are an excellent emerging model organism for studying cognitive and sensory ecology," says biologist May Dixon, lead author of the paper. "Learning plays a big part in their lives."

The bats' ability to retain information means that when they are hunting frogs, their main prey, they don't have to continuously relearn which frog calls indicate that a frog is good to eat, poisonous or too big to carry.

Dixon and colleagues trained 49 wild bats to respond to cellphone ringtones played through speakers. Bats responding to two of the tones found a baitfish reward on the speaker every time, but when they responded to three other tones, they were not rewarded. They quickly learned to fly to the speaker when ringtones indicated a snack, and not to respond to the other tones. The bats were then microchipped and released back into Panama's Soberania National Park.

Researchers recaptured eight of the bats one to four years later, and when they played the experimental ringtones again, the bats recognized and responded to the two rewarded ringtones even four years later. The experiment included 17 untrained frog-eating bats that did not fly to the sounds.

    Will any ringtone do or do they have some kind of preference? Is it those three BUD-WEI-SER frogs at least?

    I was immediately suspecting it had something to do with the brain-devouringly annoying "Crazy Frog" ringtones: https://en.wikipedia.org/wiki/Crazy_Frog [wikipedia.org]
