A sense of awe - Murmurations spark curiosity and wonder, as well as a deep appreciation for something so massive in scale and so detailed in its design. One of its greatest human benefits is the feeling of awe.

A mystery for many years - In the 1930s, many thought the birds used some kind of telepathy to communicate their flight intentions. Famed ornithologist Edmund Selous wrote, “They must think collectively, all at the same time.”

Scientific thought progressed - In the 1950s, scientists studying collective animal behavior across other species did away with that telepathy theory and instead suggested that these animals just have an extremely fast response rate.

That theory stuck - In a 2015 paper published in the Proceedings of the National Academy of Sciences, it’s called the "rapid transmission of local behavioral response to neighbors," and it enables the flock of birds (and schools of fish, swarms of insects) that incredible synchronicity.

There is no leader - While much of human behavior can be linked to top-down organization, murmurations are actually organized by the individual’s little behavior rules that, when combined, scale up to the large group.

Observe the local to grasp the global - In order to understand the murmuration behavior, scientists had to start from the individual on the local scale to grasp the total outcome on the global scale.

They can’t be aware of every other bird - In 2013, mechanical and aerospace engineer Naomi Leonard worked with Italian physicists and determined that it's impossible for one bird in a flock of 1,200 birds to keep track of the other 1,199, the real question is "Who is keeping track of whom?"

Math enters - They used hundreds of photos and plotted the position and speed of birds as they flocked in order to build a mathematical model that could identify the optimal number of flock-mates each bird must track.

The groups of seven are intermingled - All the little groups of seven touch on other individuals and groups of seven, linking them all in this greater mass, sending information about twists and turns through the group very quickly.

Three things tying the individual birds - There’s surprisingly no large-scale coordination, but instead the individual birds are merely focused on three aspects of their flight and the flight of those around them. They are as follows...

A scare tactic? - Many scientists believe the murmuration’s purpose is to confuse and intimidate predators through the combination of their size, noise, and motion.

Other reasons - There may also be communication in murmurations regarding where food sources are, and other researchers believe they could also just be a way for the birds to keep warm.

They move almost as one - Because they can take in and process information much faster than humans (called a higher temporal resolution, in science-speak), they can become something much larger together.

Humans have learned from starlings
- In 1986, a computer scientist by the name of Craig Reynolds built computer models of birds flocking and fish schooling, calling it "Boids." These programs actually provided the basis for more lifelike animation in movies, most notably first seen in the animated swarm of bats in Tim Burton’s 1992 ‘Batman Returns.’

Impressive photos of magical starling murmurations
Uncover the secrets behind this stunning natural phenomenon
© Reuters
On its own, the starling is somewhat unremarkable: short, thick, with dark feathers and a pointed bill. You’ve probably seen one or heard its chirpy song without thinking too much about it. But when they flock together, in what is called a murmuration, suddenly you’re witnessing the power and fantastic mystery of the natural world.
These mesmerizing flocks can number in the hundreds of thousands, and their appearance is reminiscent of those old cartoons where birds, bugs, or fish would form a fist or something humorous. When you see them in real life, however, they form breathtaking shapes, pulsating and warping, half threatening and half mocking our laws of nature. The spatial scale of the harmonized whole, moving more quickly than our human brains are capable of, is something everyone should see before they die.
Click through to see how they’ve captured humans’ imagination, the science behind how they pull it off (based on an article from How Stuff Works), and enjoy some incredible photos of their murmurations around the world.
