Starlings are startling in their ability to create these beautiful formations. Scientist truly couldn’t begin to understand them until they had the high-tech capabilities to analyze their movements in computers. What they discovered was amazing: the flock transcends biology. Every single starlings movement is influenced by every other starlings movement. Known as scale-free correlation, it can be best understood (although not perfectly) through looking at things like avalanches or crystal formations – on the verge of instantaneous change.
Because there is no LEADER of the formation, any starling has the ability to change the path of all starlings in the flock. Regardless of the size of the flock they remain equally responsive to all other starlings: velocity and orientation remain consistent regardless of the number of birds participating. We still cannot understand how they are able to process and respond to signals of the surrounding birds so quickly.
The most fascinating thing of all, perhaps, is that this is all in response to a predator, and the greater the threat, the more phenomenal the synchronicity. The all have and share the same goal of survival, and this singular goal allows them to create and perform at unfathomable levels.
