I was taking shots of a blackbird on the fence with a beak full of worms for it's chicks until this Sparrow hawk photobombed the shot. I wish I had opened the lens up a bit though as it was only 3 metres away.
PS The blackbird escaped unscathed
Clear shot considering the speed of the swoop. One perched on a branch in our garden, and I was set, camera ready, finger on shutter, for a take-off shot. He was half way to the next village by the time that I pressed the shutter.
