Interaction ruling animal collective behavior depends on topological rather than metric distance: Evidence from a field study
M. Ballerini,N. Cabibbo,Raphaël Candelier,Andrea Cavagna,Evaristo Cisbani,Irene Giardina,Vivien Lecomte,A. Orlandi,Giorgio Parisi,Andrea Procaccini,Massimiliano Viale,Vladimir Zdravkovic +11 more
TL;DR: It is argued that a topological interaction is indispensable to maintain a flock's cohesion against the large density changes caused by external perturbations, typically predation, and supported by numerical simulations.
Journal ArticleDOI
Scale-free correlations in starling flocks
Andrea Cavagna,Alessio Cimarelli,Irene Giardina,Giorgio Parisi,Raffaele Santagati,Fabio Stefanini,Massimiliano Viale +6 more
TL;DR: It is suggested that flocks behave as critical systems, poised to respond maximally to environmental perturbations, through scale-free behavioral correlations, which provide each animal with an effective perception range much larger than the direct interindividual interaction range, thus enhancing global response to perturbation.
Journal ArticleDOI
Statistical mechanics for natural flocks of birds
William Bialek,Andrea Cavagna,Irene Giardina,Thierry Mora,Edmondo Silvestri,Massimiliano Viale,Aleksandra M. Walczak +6 more
TL;DR: It is shown how a quantitative microscopic theory for directional ordering in a flock can be derived directly from field data, and the minimally structured (maximum entropy) model is constructed consistent with experimental correlations in large flocks of starlings.
Journal ArticleDOI
Empirical investigation of starling flocks: a benchmark study in collective animal behaviour
Michele Ballerini,N. Cabibbo,N. Cabibbo,Raphaël Candelier,Andrea Cavagna,Evaristo Cisbani,Irene Giardina,Alberto Orlandi,Giorgio Parisi,Andrea Procaccini,Massimiliano Viale,Vladimir Zdravkovic +11 more
TL;DR: This work measured the individual three-dimensional positions in compact flocks of up to 2700 birds and investigated the main features of the flock as a whole (shape, movement, density and structure); current models and theories of collective animal behaviour can now be tested against these data.
Journal ArticleDOI
Information transfer and behavioural inertia in starling flocks.
Alessandro Attanasi,Andrea Cavagna,Lorenzo Del Castello,Irene Giardina,Tomás S. Grigera,Tomás S. Grigera,Asla Jelic,Stefania Melillo,Leonardo Parisi,Oliver Pohl,Edward Shen,Massimiliano Viale +11 more
TL;DR: It is found that information about direction changes propagates across the flock with a linear dispersion law and negligible attenuation, hence minimizing group decoherence and suggesting that swift decision-making may be the adaptive drive for the strong behavioural polarization observed in many living groups.
