In our new paper we discuss the coevolution of cognition and sociality (link: royalsocietypublishing.org/doi/10.1098/...). It was a pleasure to work on this project with Andoni Sergiou, @josharbon.bsky.social, @inesfuertbauer.bsky.social, @shoalgroup.bsky.social, and @cornishjackdaws.bsky.social!

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉
We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟

✨New paper✨
How do juvenile ravens find social groups?
We describe how juvenile common ravens, who have left their natal territories seeking to join non-breeder flocks, use space with respect to other birds, and discuss what this means for social integration.

We report a neat, and somewhat counter-intuitive, finding: higher-ranking baboons get less and more interrupted night-time rest.
