Palatable versus poisonous: Eavesdropping bats must learn to identify which prey is safe to eat

Scientists found that the fringe-lipped bat, known to eavesdrop on frog and toad mating calls to find its prey, learns to distinguish between palatable and unpalatable frogs and toads through experience. The findings provide the first evidence that eavesdropping predators fine-tune their hunting cues over the course of their development.
