In particle physics, synchronized orientation is found in systems with “low noise,” in which signals are transmitted without degrading. If any one bird turned and changed speed, so would all the others. Regardless of size, the correlations of a bird’s orientation and velocity with the other birds’ orientation and velocity didn’t vary. Some had just over 100 birds, and others more than 4,000. Parisi’s team recorded starling flocks on the outskirts of Rome. In starlings, “being critical is a way for the system to be always ready to optimally respond to an external perturbation, such as predator attack,” wrote researchers led by University of Rome theoretical physicist Giorgio Parisi in a June 14 Proceedings of the National Academy of Sciences paper. The closest fit to equations describing starling flock patterns come from the literature of “criticality,” of crystal formation and avalanches - systems poised on the brink, capable of near-instantaneous transformation. That phenomenon is known as scale-free correlation, and transcends biology. It’s as if every individual is connected to the same network. It doesn’t matter how large a flock is, or if two birds are on opposite sides.

Mathematical analysis of flock dynamics show how each starling’s movement is influenced by every other starling, and vice versa. Long (buy the book on Lulu.Amazing Starling Flocks Are Flying Avalanches By Brandon Keim, Wired Science JTo watch the uncanny synchronization of a starling flock in flight is to wonder if the birds aren’t actually a single entity, governed by something beyond the usual rules of biology.

I hope these words inspire you to keep looking up. Who said winter is boring never was awed by Starlings playing in a evening sky.

What about the summer, do you see flocks of Starlings?.

How does weather affect the murmuration? Is it windy? Cloudy? Clear and sunny? Rainy?.

How often does the flight display happen? Every day?.

What trees do they use for roosts? Evergreens or bare deciduous?.

I used the Grinnell Scientific Nature Journal model. I noted the time, temperature, weather conditions, and any other information I thought would be scientifically relevant. These last few weeks, I went outside or watched from inside the house as the Starlings gathered in the Tulip tree, then fly in the sky. Citizen Science and Starling Murmurations European Starling (Sturnus vulgaris) on city light pole in Philly. Do they need a reason? Do we need a reason to watch in delight as they flash dance and flash mob through the evening sky? The only way to know for sure would be to ask Starlings why they do it, if they would even tell us. Scientists have created computer models of flocking birds. Scientists don’t seem to know why Starlings dance together in the sky before they settle in for a night’s sleep. Sunset is the time the birds gather in flocks and then leap into the sky to fly in synchronized display.

Across the pond, Starling flocks can number millions of birds. In the U.K., Starlings from continental Europe arrive when the winter is colder and easterly winds blow toward the British Isles.

In the Starlings original home, Europe and the United Kingdom, murmurations occur October through March. So, murmuration happens in the late autumn through late winter, and not in the breeding season.
