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!

Excited to introduce the Latent Layers Framework – now out in @behavecol.bsky.social – to help think through when and why network differences confound inference in (comparative) social network analysis! 🧵

In an increasingly divided world, how do strangers become friends? Parakeets might have something to teach us! New paper on formation of affiliative relationships, led by Dr. Claire O’Connell doi.org/10.1098/rsbl...
Graphic showing the paper title “Monk parakeets ‘test the waters’ when forming new relationships” in the journal Biology Letters. Also features photos of the co-authors (Claire, Annemarie, Gerry, and Liz) as well as the issue cover photo of two marked monk parakeets from Claire’s work grooming each other. Also shown are some of the main plots of the paper showing how the parakeets escalate their behaviors from low risk/low investment (like proximity) to higher risk/higher investment interactions (like preening/grooming)

Vocal convergence during formation of social relationships in vampire bats royalsocietypublishing.org/doi/10.1098/...
Vocal convergence during formation of social relationships in vampire bats | Proceedings of the Royal Society B: Biological Sciences
In many group-living birds and mammals, the formation of affiliative relationships is hypothesized to cause vocal convergence (an increase in call similarity between individuals). However, testing this causal effect can be difficult, because it requires ...

Here we find that the social environment, notably vocal and aggressive interactions, are linked to cognitive development in magpie fledglings.

New paper!

We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-series—that is, without the need to aggregate them over time.

www.biorxiv.org/content/10.1...
Each dyad (a, b) moves through four discrete states over time, represented by coloured circles. The dyad remains in a given state for a certain duration, or "holding time", before transitioning to a new state according to state-specific transition probabilities, indicated by arrows showing all possible (non-zero) transitions.

Social relationships are powerful predictors of fitness across social animals. But *why*?

In our new @cp-trendsecolevo.bsky.social paper, we outline testable predictions for why relationship quality and quantity adaptively vary across socio-ecological contexts.

The Adaptive Relationships Framework illustrating how broad socioecological pressures shape the social solutions animals use to meet these challenges, and how these lead to social strategies and emergent structures that help them gain access to those solutions.

Are you studying animal sociality?
