🚨New animal linguistics paper🚨

Together with @geoffreymesbahi.bsky.social and @maelmleroux.bsky.social, we tried to finally answer this question: Do titi monkeys have complex syntactic skills?

Thank you to my lovely collaborators @geoffreymesbahi.bsky.social and @maelmleroux.bsky.social for the (much-needed) final push!
