We have a colony of house sparrows who hang out in our garden hedge, particularly on sunny afternoons.
There are over a dozen of them but it is difficult to capture them on "film". So when they ventured up to the highest branches it was my chance.
I wasn't the only one to notice. The sparrows disappeared in a trice when this chap showed up.
Postscript. The sparrowhawk turned up again the next day when I was out in the garden and dive bombed me on his way out. I couldn't believe he would attack me but still found myself flapping my arms just to be on the safe side. A fearsome sight.
