Birds Swarming (like fish in the sea)

We can’t take our eyes off of the swirling blackbirds you might see at dusk, thousands of them flying through the air together in what looks like controlled chaos. You can’t even believe your eyes when you see it, resembling computer-generated effects from a sci-fi movie. Truly a sight to behold, we wanted to understand why the birds might do it.

For years, scientists have wonders about murmurations. Recently, they have started to use cameras and computers to understand the mystery of murmurations. Scientists have been surprised to learn that the flying patterns of murmurations have more in common with physics than biology. Much remains unknown about murmurations. However, scientists now believe they may be able to describe murmurations using the principles of physics.

Scientists believe murmurations are similar to other systems, such as crystals forming, avalanches, metals becoming magnetized and liquids turning to gases. These systems are “on the edge,” which means they’re ready to be completely transformed in an instant.

Like the elements of these other systems, each starling in a murmuration is connected to every other starling. As shown in today’s video, when a murmuration turns in unison, scientists believe it’s like a phase transition.

It’s easy to understand how one starling knows to turn when its neighbor turns, since they’re close together and can see each other. What scientists still don’t understand, though, is how hundreds or thousands of starlings seem to know when to turn simultaneously, when birds at opposite ends of the flock are separated by space and hundreds or thousands of other birds.

Regardless of the size of the murmuration, all the birds seem to be connected to the same network. This phenomenon puzzles scientists, because it goes beyond what we know from biology about how animals behave. That is to say find the physics familiar but the biology impossible. The mystery of the murmuration is a fascinating example of a natural phenomenon that hides secrets about the world that scientists have still yet to uncover!
