Bats have been shown to be able to learn from other species of bats, and thus provide the first clue that species can teach other species things in the wild

When compared to other mammals of their own size, bats are really smart animals. Some of the species form huge colonies and exhibit extraordinary social behavior, such as apparent altruism where some bats will share food with other bats who are hungry. They are also able to grow to be over 40 years old, extremely old compared to what you might expect.

Scientists have been testing the intelligence of bats for a while, and even figured out how to make the bats teach each other to complete small “puzzles” in order to get food. This is really amazing by itself, but a research group from Smithsonian Tropical Research Institute (STRI) in Panama wanted to take it another step further and test if they could get bats from one species to teach bats from another species how to solve these puzzles, and it turns out that this was not as difficult as they even imagined.

The study design

The first experiment began when the research team tested if fringed-lipped bats (Trachops cirrhosis) would be able to learn from other bats from the same species. Do test this, the research team taught them to recognize a computer-generated tone that would be linked to a food reward.

The tone was not resembling anything, but in the wild these bats will hunt frogs when they hear their callings, so they are adapted to use audio cues as a signal for beginning a hunt and getting food.

What they found out was that the bats would eventually learn to associate the signal with food, but if they added new bats to a group that had already learned it, this new group would pick up on the association a lot faster.

Social learning is not uncommon at all, but it’s not really that often that we get to see it in lab conditions like it. Anyway, once the scientists were sure that the fringed-lipped bats would actually teach each other to respond to the correct signal, it was time to step it up.

This time they also introduced round-eared bats (Lophostoma silvicolum) into the experiment cage. As you can see from their scientific name, these two bats do not belong to the same genus, but they are ecologically much like each other, and exhibit a lot of the same behaviors such as hunting on audio cues.

These bats learn just as fast from the other species

The results from the experiment is pretty cool, and it turns out that the round-eared bats were able to pick up the signal just as quickly from the fringed-lipped bats as compared to the control group where they taught it to the same species. Apparently they are capable of learning from each other just as fine as they learn from their own species, which is really cool!

While there are some examples of one species teaching another species things, these examples are often seem between primates (mostly humans and captive apes) and domesticated animals such as dogs, cats or other pets. This is the first good example we see of two wild species being able to teach each other things, and this could also potentially happen in the wild.

It's important to keep in mind that this all happened inside a laboratory, but the animals were still considered to be wild, since they were not domesticated.

Why learning from other species is a great advantage to have in the wild

It makes perfect sense that some species are able to learn stuff from other species in the wild, because environmental learning is a much faster and better response to some environmental changes compared to just having an evolutionary response that could potentially take many generations before it takes full effect.

So when you are able to learn things from other species, such as how to predate on a certain species, this will give the learner an instantly benefit, and increasing its fitness without having much of a downside.

This research shows us that different animal species might actually cooperate to solve the issues faced when struck by environmental change, but to what extent this is happening in the wild is yet to be determined. It's still a very nice "proof of concept", and it would be really cool if scientists actually started to looking for this type of interspecific learning in different animal populations in the wild. Who knows which animals end up being shown to learn from others?
