I just remembered watching TV then suddenly, a flock of birds were filmed and they turn their direction without hitting other birds of their kind...

Unlike us who can only see in front of us, birds can see both sides clearly (right and left) giving them 180 degree view.
So, it's not a problem for them to adjust during the turns.

Most of the birds can see almost close to 270 degrees without turning their heads. If they turn even a 45 degrees, they would cover the remaining 90 degrees as well. So, it is very easy for birds to see around when they are flying without much head movement.
Interesting Fact: Owl can rotate its head to 290 degrees both the ways.

That is a good question. If we are talking of birds of the same feathers flying together as in groups ..the answer is that like you and I...BIRDS HAVE EYES TO SEE where they are going..since their means of movement is thru flight..their INSTINCT tells them how far they are from each other guiding their velocity and manuevering to avoid collision or hitting each other inflight. i WOULDN'T BE SURPRISE IF THEY DIDN'T HIT EACH OTHER BECAUSE THEY HAVE EYES TO SEE...BUT RATHER I WOULD BE SURPRISED TO SEE BLIND BIRDS FLYING WITHOUT HITTING EACH OTHER!!!
Ever heard of the saying " BLIND AS A BAT?" well bats don't use their eyes to see while in flight but they don't collide with one another and never missed their target. Have you ever wondered why? Bats fly without seeing but rather ..these nocturnal birds(?) fly at night using their sensitive hearing like a radar..just like dolphins. They make use of the Doppler Effect.

Now give those birds some credit with regards to their own sense of sight and reflex.
happy bird watching!!!

The same kind of on-board radar that people use when walking in the mall or driving on the expressway
