And with the juveniles, they actually showed interest in those toxic frogs and toads, which really, coupled with our other experiments over time, led us to think that that learning period is critical for them to develop this fine-scale discrimination of what's safe and what's not in terms of prey approach in the forest.

This species in particular is fascinating. So these are not even very close evolutionarily, frogs and bats. And yet these bats have figured out basically how to interpret these frog calls, that this one is palatable and this one is poisonous. And I can consistently rely on that for correct discrimination between meals that are safe and meals that are quite risky.

So we're fascinated by eavesdropping behavior. And you find eavesdroppers across sensory modalities, across the animal kingdom.

Absolutely. Humans do it too. But no, you find it really in nearly every taxonomic group. that you look at. And I think that the ones that we haven't found it in is just because we haven't looked hard enough yet. So this is the first study to our knowledge where we've looked at how eavesdropping predators acquire that specific behavioral strategy.

So I'm really hoping that the study spurs interest in all of the fantastic biologists all over the world who are interested in eavesdropping behavior. Because it would be really, really fascinating to see if the patterns that we're seeing with these bats are similar across other predators that eavesdrop on the communication signals of their prey.
