Modelling starling murmurations with maths
Researchers at the University of Warwick are using mathematical models to unpick how vast flocks of starlings create their mesmerising shapes.
In a computer model of a flock, they built up a series of rules based on what each "bird" would be able to see in front of it.
The model, shown here driving a flock of 100, showed that a flock would naturally tend to form at the tightest density that still allows the birds to see in many directions: a "Goldilocks" density that is not too close together, and not too far apart.
The work is published in the journal Proceedings of the National Academy of Sciences (PNAS).
