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
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
The STARFLAG handbook on collective animal behaviour: 1. Empirical methods
Andrea Cavagna,Irene Giardina,Alberto Orlandi,Giorgio Parisi,Andrea Procaccini,Massimiliano Viale,Vladimir Zdravkovic +6 more
TL;DR: 3D studies of collective animal behaviour in three dimensions with small groups highlights the difficulty of obtaining high-quality 3D data for birds and mosquito studies, where the number of animals is very low compared to natural conditions.

An empirical study of large, naturally occurring starling flocks: a benchmark in collective animal behaviour
Michele Ballerini,Nicola Cabibbo,Raphaël Candelier,Andrea Cavagna,Evaristo Cisbani,Irene Giardina,Alberto Orlandi,Giorgio Parisi,Andrea Procaccini,Massimiliano Viale,Vladimir Zdravkovic +10 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 - and discusses these as emergent attributes of the grouping phenomenon.

The STARFLAG handbook on collective animal behaviour: Part I, empirical methods
Andrea Cavagna,Irene Giardina,Alberto Orlandi,Giorgio Parisi,Andrea Procaccini,Massimiliano Viale,Vladimir Zdravkovic +6 more
TL;DR: The main technical problems in 3D data collection of large animal groups are reviewed and how to solve the stereoscopic correspondence - or matching - problem is explained, which was the major bottleneck of all 3D studies in the past.
