The Social Life of Bats (nautil.us)

Bats are small, and mammals, but are very different from "small mammals". They live for 10 to 30+ years, typically have just one or two pups per year, and spend the whole summer raising their young.

In a roost full of one million bats(!), a mamma bat can recognize and return to her own waiting pup. We record such a diversity of "social calls" with full-spectrum bat detectors that they almost certainly have individual names for each other.

Bats have culture in the sense that they pass on knowledge from individual to individual, over generations, for decades or centuries. Migratory Mexican Free-Tailed Bats will travel many hundreds of miles to return to a specific cave roost, which they learned from their family and friends, and will teach to their offspring. Different populations of the same species of bat will have learned to return to a different cave roost.

They have an intelligence that we cannot fully understand, living in a world where one of their primary senses is echolocation. Contrary to that old saying "blind as a bat", they've also got the 5 senses that we have as well, including good sight. When a Big-Eared Corynorhinus looks you in the eyes, you can see intelligence staring back at you.

(I am speaking exclusively about echolocating microbats, not "flying fox" megabats. I have ~15 years experience recording and analyzing bat echolocation and managing bat hibernacula and maternity roost caves.)


I'm surprised that we haven't seen an animated movie about bats similar to something like The Rats of Nimh. Their world seems so complex and mysterious. Much lore to ponder for a young mind.


C'mon Pixar...give us a bat movie


Bats best socialise amongst themselves. I like bats, we have fruitbats locally but they're best loved at a distance I find.


Okay good, because fairies seem to be freaked out by them

For your enjoyment, flying fox film run upside down to "Russian Doll" which is the Goth disco we all need:

The smell is .. unbelievable up close. When they fly off at dusk and return at dawn in huge flocks it's lovely, they swoop over me on the Brisbane river when I row before sunrise. Farmers are less happy generally. If a colony roosts in a small town it's a big deal.


I remember watching them exit Carlsbad caverns. Amazing.

Thanks for the links!


Bats socialize more than me. Good to know.


Hey, if you want to hang out, upside down, above fetid layers of your own feces then by all means get in touch.

I can't say I'll join you, but I do promise to register everbody on my new social platform Soundr (echo locate your ideal partners today!).


When I read the title "Social life" of some dumb animal, I was thinking the same :(


When I read "social life of some dumb animal", I immediately thought of a rental Lambo and some TikTok stories
