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. 🐟

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.

Our paper is published today in Current Biology and is featured on the cover!

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