Marmoset monkeys coordinate vigilance while feeding.
Individuals in a marmoset monkey pair take turns to be vigilant while they are feeding. By modeling the monkeys as coupled oscillators, we investigated how this turn-taking pattern emerges over time. We find that marmosets have remarkable flexibility and control over this turn-taking behavior. The more out-of-sync they are initially, the more effort they put into synchronizing with each other, thus facilitating rapid coordination of vigilance. Phaniraj et al 2024
