|Murmuration of Dunlin over Boundary Bay|
I'm sure everyone has at some point in their life seen a large flock of birds clustered close together, flying in some sort of strange formation that defies logic, and wondered how they managed to do it without crashing into one another. I'm not talking about the orderly V-shaped procession of migrating Canada geese that skillfully allows each bird to change positions as they tire or take the lead. I'm talking about hundreds or even thousands of a particular bird species that suddenly band together and act as a single entity in some strange organized pattern.

What all these birds, insects and fish have in common is the ability to move in concert as if they had a single mind and do it without bumping into one another. By simply keeping an eye on their closest neighbours, moving in the same direction, and staying close together they are able to move as one giant organism. In the case of birds, scientists have determined that each one keeps an eye on a maximum of seven others and this allows them to maintain perfect synchronization.
|Swarm of bats|
Warm blooded creatures such as bats, ungulates, and humans also form swarms or murmurations though humans are more successful when they are walking or running rather than operating a vehicle. But thanks to studies of birds in particular and mathematical models of fish, new advances in artificial intelligence and robotics may start to make vehicle murmurations safer. There is also evidence of plants and algae using swarming techniques to optimize growth.
But while being part of the crowd can perhaps offer some measure of safety, the herd instinct also discourages independent thinking and as humans this makes us particularly vulnerable. With social media and skillful advertising shaping the way we think and the choices we make, our "group thinking" society is making it all too easy to behave like lemmings. Perhaps before we rush off to join the latest in-crowd we should take a closer look at where it's going.
