1/5 What counts as a communicative interaction? This was a recurring question at the recent Computational and Mechanistic Analyses of Communicative Interactions symposium, where ESP's Maddie Cusimano and @loganjames.bsky.social presented their research on carrion crow and zebra finch communication.
CBC Quirks and Quarks did an extended piece on our recent Science paper about beauty in animal vocalizations. alongside the science this also featuried postdoc @loganjames.bsky.social and yours truly producing animal vocalizations ourselves (lol)

Enjoyed diving into the fascinating work by @loganjames.bsky.social et al. on shared preferences between human and non-human animals Liked it so much, we wrote an eLetter, now posted in Science 😅 Our take? There's another side to acoustic preferences worth exploring: idiosyncratic taste
Thank you NPR for this great coverage of our research!! you can read the paper here: doi.org/10.1126/scie...
Humans and animals find the same sounds 'beautiful'
Charles Darwin theorized that a sound, smell or color that's attractive to one species can be preferred by others too. A new study finds humans and animals do share preferences for certain sounds.

Super excited about this new paper! and eternally grateful to the amazing coauthors, the wonderful network of colleagues who gave us stimuli, and all of the thousands of people that listened to animal sounds for us!
samuel mehr@mehr.nz · 7mo agoout now in Science: @loganjames.bsky.social collected pairs of sounds in 16 species where we *know* which sound is more attractive (to that species) he played them to ppl on themusiclab.org, asking, in each pair, which was nicer. humans agreed w other animals doi.org/10.1126/science.aea1202
New preprint on vocal communication in zebra finches! 🐦 Earth Species Project and McGill University analyzed over 1.5 million female zebra finch calls to understand how female zebra finches modulate their vocalizations during natural exchanges.

The Conversation U.S.@us.theconversation.com · last yr.🦇 Baby bats almost get themselves killed while learning to listen for the right prey to hunt. Smithsonian researcher Logan S. James and his team spent decades studying these acoustic assassins in Panama and the results were wild. #bats #science #predators #frogs
Beautiful, creative work from @loganjames.bsky.social et al! doi.org/10.1101/2025... 1. Humans share sound preferences w animals (even insects!) 2. Musical experience predicts agreement w animals "...our data indicate a more expansive shared ‘taste for the beautiful’" #bioacoustics #prattle 💬
New preprint from a bio-psych collab many animals have preferences for sounds in their species (eg, I'm a frog, I like deeper frog croaks bc better frog mates sound deeper) @loganjames.bsky.social tested if humans are sensitive to these prefs in 16 species we are! www.biorxiv.org/content/10.1...

The ontogeny of decision-making in an eavesdropping predator | Proceedings of the Royal Society B: Biological Sciences
Predators use prey-emitted cues to assess and localize potential food sources. Sexual advertisement calls offer conspicuous cues for eavesdropping predators. While the ontogeny of predatory behaviour ...

my most recent paper just came out! we wrote a news story about the article here:
Young bats learn to be discriminating when listening for their next meal
By listening to a frog call, adult bats can tell which prey are palatable and which are poisonous. Young bats must acquire this ability over time.

New paper led by Lidya Yurdum (PI: @mehr.nz )—we studied people in 52 countries in an experiment translated into 31 languages, testing a core set of intuitions about music—for at least these intuitions, they were highly consistent! t.co/vys4n7b49o
Don't worry, linguists. Biologists don't know what a species is, or what life is,

do you hear like a deer? our new gamified experiment 🧪 Calls of the Wild tests what animal you're similar to (in terms of your auditory preferences). give it a try at themusiclab.org/quizzes/havoc (i got 'mammals')
