How do birds not crash into each other?

Question

I’m not talking about geese. I’m talking about those huge flocks of birds. There’s 1000s of them and they never collide with each other. How?

They *do* collide with each other. It’s just not a big deal when they do.

When you bump into someone in a crowd, you just instinctively adjust in less than a second and continue on your way. Same thing with birds, bats, etc. It doesn’t significantly disturb their flight path to brush up against another body that is already moving in generally the same direction.
