For pigeons, follow the leader is a matter of speed

A study on homing pigeons reveals that speed plays a crucial role in determining flock leadership. Faster birds lead and learn to navigate better routes, while slower birds follow and improve their skills over time. This simple yet effective mechanism explains the emergence of leadership in bird flocks.
