Scientists have various theories about what causes starlings to swarm and flock together as they fly in unison, but a final explanation still eludes researchers. Such aerial flights of hundreds or thousands of these birds in hypnotic displays of coordination and rhythm are called murmurations. Scientists are studying such behavior in nature to see how swarm theory can be applied to artificial intelligence and solve human problems. In birds, these groups may be eluding a hawk, gathering strength for upcoming migrations, working together to generate heat or responding to magnetic forces unseen to humans. Or perhaps a murmuration is something more--something that science can't explain simply in quantifiable terms. Maybe it is a dance to music that only the birds can hear or maybe it is play on a level that only birds can appreciate. Whatever a mumuration is, it is a joy for humans to witness and surely makes many wish that we too had wings to fly with such freedom.
