In reply to Michael Hood:
Always a great experience.
I had it last year. Flash of something out of the corner of my eye as I was washing the dishes. Delighted to see a sparrowhawk v pigeon battle and rushed to grab my camera.
She brought it down, wrestled for a while before it escaped and darted under to safety a greenhouse.
Madame sparrowhawk loitered with intent and returned for another attack, hauling the pigeon out before it broke loose again. Again she loitered but flew off never to return.
Many minutes later along came Vegas, the neighbours cat, who proceeded to follow a feathery trail to the green house. Hauled out the pigeon which again performed a great escape and flew off to freedom.
Made my day.
