Get a look at some of the planet’s great gatherings, creatures that come together in inconceivable numbers — sometimes in millions, billions, even trillions. Included are bats and bees, locusts and ants, monarch butterflies in Mexico, 17-year cicada hatches, grunion in the Sea of Cortez and carp in the Mississippi River, sardine runs off the coast of South Africa, super flocks of parakeets in the Australian Outback, mayflies on the 4th of July and even penguins and wildebeest. Some gather to breed or to migrate, some for protection, some simply to keep warm in the cold. But in the process, a kind of super-organism is created in which individual intelligence is superseded by a collective consciousness that shares information and moves with a single purpose for the benefit of all. Check out swarm intelligence, essentially a living embodiment of social media in the natural world.
