Thanks everyone.
I have to admit. I was initially setting up this shot with only the hedge and the beautiful sky background. I was several shots into it when the birds appeared out of now where.
it reminds me of that wonderful time of year when all birds suddenly rise to a dance in the wind scattering their wings in the air-as Andy Goldswarthy did many years ago when he photographed himself throwing handfuls of stone up-it is so beautiful capturing that moment of magic when there is no contrivance only spontaneity-thank you!
