They respond to the bird next to them. If the bird next to them turns, they turn. It works the same way with schools of fish. There are computer simulations that show how easy it is to do with very few, simple instructions. No thought goes into it, it is an automatic response.

Only they know. I think they follow the bird(s) next to them. Starlings gather this way when they migrate to avoid beig eaten by preditor birds.

Their internal compass--many, if not all birds, use the degree of the angle of the sun while traveling long distances.
