Flocks of acrobatic starlings have long delighted observers, from Shakespeare to the present day. The birds—sometimes by the thousands—often seem to move as one, coursing through the air at breakneck speeds, turning on an instant.
We recently published video of a beautiful starling swarm in the Netherlands. So many wings can be heard flapping in that video that it's easy to get why starling swarms are called murmurations.
This week, another mesmerizing video of a starling swarm was published, this time in the U.K.'s Sutton Courtenay, Oxfordshire (see above). That video shows more intriguing patterns in the sky as thousands of birds twist and turn in unison.
Starling murmurations tend to occur most often at dusk, when the birds gather together for the night. They can consist of a few hundred or tens of thousands of individuals.
Scientists think the rapidly changing directions may confuse predators.
Resembling the smoke monster from Lost, the mechanics of the swarm-like behavior aren't fully understood. But recently scientists have determined that murmurating starlings coordinate their movements with their seven nearest neighbors.
In other words, when one bird changes speed or direction, the seven closest birds respond in kind. In this way, information spreads across the flock rapidly (read more about animals that swarm, from insects to bats to crabs).
Such swarm intelligence is also increasingly being tapped by human beings, who are using the rapid, adaptive technology to program computers and develop robots, among other applications. Swarms are also how science fiction writers often depict the future of nanotechnology.
