3BT


In a tree lined village street at Lingfield, as I drive cautiously along the approach to a busy junction, a jay emerges from the last tree and comes gliding down towards something I cannot see that lies in the path of my truck.  For a second or two as we approach one another, I am able to look down on him as he spreads his beautifully coloured wings in preparation for landing, but just as I am about to panic so he changes his mind and swoops up again to disappear beyond my shoulder.

In a winding country lane running along one of the Wealden ridges, as I slow to make room for an oncoming van, a kestrel with wings held high and tail in the up position, drops down along a dead straight landing path, touches the road for half a second, and then flies back up and away, along that very same line; carrying something in one talon that is small enough to be a vole.

As the truck trundles along the edge of a vast undulating field of wild flowers, so a skylark slowly descends until she vanishes in to a mist of buttercups.
