Murmuration

[Wisteria]

I have been following the uk destinations to witness murmuration of the starlings, its always fascinated me with their beautiful display, there is a link I found to the roosting in reeds, which explains their timing from September to November, but how do they fly in such quantities and never bump into each other? their timing is unique, I wonder if they plan their flight, and how they do it.. creating beautiful patterns in the sky, if anyone has observed this, and witnessed the perfect symetry like signs in the skies forming shapes of whales and other life forms, throughout history there has been a symbolic of intuition and change. This makes sense as one must use instinct and energetic sensitivity to know what is supposed to come next much like the starlings flying with hypnotic fluidity, sensing the change in direction, do we take this for granted?
