Improvements in our ability to collect and process real-time data from animal behaviour have lead to increasing interest in the quantitative analysis of collective motion in various species. This motion can be characterised as movement of a group of animals that interact among themselves and with the surrounding environment to preserve the cohesive form of the group. Examples of this motion include a flock of birds, a fish school and a group of deer or sheep. The problem becomes particularly challenging as the group dynamics and the individual dynamics need to be disentangled for biological analysis. Within this framework we describe a new mathematical technique that may be applied in order to understand animals group movement and behaviour. In particular, we model and track the behaviour of a small flock of pigeons and verify using real data that the dynamics of each individual are a combination of two different mechanisms (local and global).
