Why Don't Birds Fly Into One Another?
One answer: Air flows naturally generated during flight may prevent collisions, allowing even individuals with different flapping motions to travel together.
Another answer: Researchers put parakeets into an air tunnel and had them fly towards each other. They found that each bird always veers right and changes altitude to avoid mid-air collisions.
But what about instantaneous flight, as in this picture of migrating snowgeese taken by Ray Hennessey via Birdshare....
These birds are too close for thought, yet not one bird knocks another out of the group, and no one bird is the leader. Instant flight changes and missed collisions may be the result of a group cognition, meaning one thought is shared by a large group acting as a single being.
Is it possible? Bees show this behavior, too. Wild dogs seem to be of one mind when they hunt in a pack. Many beings sharing instant connected behaviors -- is that an expression of a higher "mind" than we humans DO NOT seem to have, so we try to dismiss it with other explanations?
It's Nature's magic -- and brilliance -- is what I think.
