Does this ring a bell? Wild bats can remember sounds for years. There are certain skills that once we acquire them, we rarely have to relearn them, like riding a bike or looking both ways before crossing a street. Most studies on learning and long-term memory in the wild focus on a handful of animal species. Now, in a publication in Current Biology, researchers working at the Smithsonian Tropical Research Institute (STRI) share the first report of long-term memory in frog-eating bats (Trachops cirrhosus).
