    Obviously. The question is how the birds manage to maintain the right
    distance, particularly when the whole flock turns on a dime. Either the
    brain is running an incredbly elaborate motion program or the flock is a
    morphic field in which the birds are "particles." While the latter
    possibility might strike you as being "weird," the former possibility
    require neural computing processes unimaginably more powerful and rapid
    anything humans have ever devised.

    No, just rapid reaction time, and the reaction times of birds, like
    their heartbeats, are a lot faster than ours, crerating the illusion
    that they are all changing direction at the same time when actually
    there is a small reaction time involved.

    Have a look round for a boids variant (most have probably seen it
    already): Simple sim of birds (from The Bronx I suppose) with a handful
    of rules (stay a rough distance from your neighbour, etc.) and they do
    most of the things all flocks do - it looks really organic, but needs no
    'hand of god' style guiding force. Also I read somewhere (er...) that
    the time the turning 'wave' takes to cross the flock is well within the
    reaction time of the birds/fish etc. As for the intentionality of the
    flock, just watch some crowd violence to see how these para-democratic
    decisions are made.
