Flocking behavior refers to the collective movement of a group of animals, such as birds or fish, that coordinate their actions to move as a cohesive unit. This behavior is often seen in species like starlings or sardines, where individuals follow simple rules, such as aligning with neighbors, maintaining a certain distance, and avoiding collisions. The advantages of flocking include increased protection from predators and improved foraging efficiency. By moving together, the group can confuse predators and make it harder for them to target a single individual. Flocking behavior is a fascinating example of how simple interactions can lead to complex group dynamics in nature.
