The collective dynamics of active swarms such as bird flocks and fish schools emerge from the complex, and often competing, interaction involving alignment, cohesion and collision avoidance. The authors propose a minimal flocking model with vison-based steering interactions, revealing a unique transition from order to disorder reminiscent of a Berezinskii-Kosterlitz-Thouless transition, which could enhance understanding of rapid flock responses in biological systems.
