Chimpanzees rationally revise their beliefs The selective revision of beliefs in light of new evidence has been considered one of the hallmarks of human-level rationality. However, tests of this ability in other species are lacking. We examined...

Chimpanzees rationally revise their beliefs. Would be interesting to do a double blind experiment with humans.

Vocal efficiency in crows - Animal Cognition Many communicative systems have been selected for efficiency, shaped by the trade-off between information transmission and energetic or temporal constraints. Linguistic laws such as Menzerath’s law—pr...

1/3 Reading minds through facial expressions

The cognitive processes involved in decision-making in mice can be understood by observing their facial expressions. This would allow non-invasive access to their decision-making processes.

We just published a new global bird phylogeny. It synthesizes the work of thousands of researchers before us, and it will grow and improve over time. @snacktavish.bsky.social @birdsoftheworld.bsky.social www.pnas.org/doi/10.1073/...

Now published!!!! www.nature.com/articles/s41...

Very grateful to @asab.org for giving me the opportunity to present my Master thesis project with a Flash Talk 🐒!! Seeing many excellent pieces of research was amazing and inspiring. Can't wait for the next one! #ASABSpring2025

Want to keep up with the research you just learned about over the past few days? Follow the speakers and organizers of #ASABSpring2025 with our starter pack!

Stress responsiveness in a wild primate predicts survival across an extreme El Niño drought White-faced capuchins with a stronger stress response to previous droughts were more likely to survive a severe El Niño drought.

Can stress help monkeys survive? New research shows that on wild capuchin monkeys with stronger stress responses during previous droughts were more likely to survive an extreme drought. Study by Leakey grantees @sccarrera.bsky.social @irene-godoy.bsky.social @jbeehner.bsky.social & colleagues.

Language-like efficiency in whale communication Whale vocalizations follow efficiency rules seen in human language, revealing striking similarities in communication systems.

Do whales optimize their vocalizations for efficiency, just like human language? 🐋🎶 My latest study in
Science Advances (@science.org) suggests they do—following linguistic laws seen in human speech. 🧵 www.science.org/doi/10.1126/...

Migrating Birds Sing to Team Up with Other Species Songbirds may socialize across species during nighttime migrations

Nocturnal flight call recordings have revealed how different songbird species cooperate during migration. Cool #ornithology research led by WOS member Benjamin Van Doren!

Hi! I'm looking for PhDs and other research opportunities in animal behaviour. Could you add me? It would be very helpful!
