Each bird follows three simple rules:
- Separation — steer away from nearby neighbors to avoid crowding
- Alignment — match the heading of nearby neighbors
- Cohesion — steer toward the average position of nearby neighbors
These local rules produce emergent flocking behavior with no central coordination.
