Buteo Buteo, aka the common buzzard.

While out in the garden this afternoon we heard the familiar mew of a buzzard and looked to see where it might be. Delighted we were to spot a pair cavorting about in the air over the wood. One settled briefly in a tree at the top of the street, hence the slight fuzziness of this - it was taken from some two hundred yards or even metres in new money. We managed to grab a few shots before they soared out of sight and this was my best. The trouble is holding the camera steady enough when the lens is fully wound out. Any tips anyone?
