buzz off

I didn't have much chance of a photo today but did spot a pair of buzzards overhead as I was driving. Quickly pulled over, got the camera out of the boot which is normally followed by the birds have flown off and the opportunity is missed. However whilst the birds had got more distant again this time there was now a dog fight going on and a smaller bird was being warned off. Only when I got the image on the screen did I see it was a sparrowhawk in the dual.
