Constructing a nest underwater is no easy task! But shell-dwelling cichlids are expert architects, instinctively transforming empty snail shells into protective nests.
Take a deep dive into the new cichlid research from our Institute!

New paper on precise tool use learning in carrion crows @currentbiology.bsky.social. We show that—like New Caledonian crows—expert carrion crows pay close attention to the working end of their tool, suggesting tool integration into their peripersonal space. 🧵 & vids! 👇

New paper from my group led by Odd Jacobson, former PhD student & current postdoc @livingingroups.bsky.social : How do animal groups simultaneously balance between- and within-group competition in dynamic environments and does this impact movement and space use? www.biorxiv.org/content/10.1...
“the widespread appeal of animal tool use is partly due to anthropocentrism”
👍 for this new comparison of how animal tools and nests are talked about, from Sally Street et al.
The need to slap a human-like ‘intelligence’ label on animals is a symptom of this bias (writing a book on that now) 🧪🪹🔨

6/n
Overall, our study shows how computational modelling can link observed behaviour to hidden cognitive mechanisms, and probe their generalisability -- we hope this encourages wider use of these approaches in animal cognition research! 🌐📝⚙️🧠
🧵5/n
Using cognitive model estimates, we ran simulations where material rewards varied. Payoff structure -- not (dis)satisfaction -- drove social material choice. But bigger rewards didn’t mean more copying. So, preliminary insights into how material-use strategies may generalise e.g., in tool use.
🧵4/n
We link males' material choices to two asocial and two social latent learning parameters -- their decisions are dynamic! -- to provide the first formal mechanistic evidence for the cognitive basis of birds’ nest building ⚙️🧠
🧵3/n
Zebbie nest-builders seem to *copy-if-dissatisfied* with prior material-experience, particularly at 1st choice -- this suggests they recognise the utility of social information.
