This video shows the visualization of the model for individuals with interaction strength χbalanced = 8.0. The critical density, ρc, for the onset of collective motion is ρc ≈ 58m−2 for N=576. The movie shows individuals at a super-critical (higher than the critical) density, 80m-2, where the order parameter is above 0.5. This research was published in the journal Proceedings of the Royal Society B in the paper: Nutritional state and collective motion: from individuals to mass migration by Sepideh Bazazi, Pawel Romanczuk, Sian Thomas, Lutz Schimansky-Geier, Joseph J.
