Bird flocks achieve coordinated flight through local interactions among individuals rather than a leader directing the group’s movement.
In a newly listed Oxford talk, collective-behaviour researcher Steve Portugal brings together biomechanics, physiology and social interaction to explain how birds maintain cohesion, move through complex landscapes and balance aerodynamic costs against social benefits. The central theme is emergence: relatively simple interactions among neighbouring birds can generate adaptive, coherent patterns at the scale of an entire flock.
