Is this a sparrow Hawk?

I got a new visitor to my garden this morning. It sat at the top of the tree for almost 40 mins. I took several photos but couldn't get very near so I'm sorry its a bit blurred due to zoom. I've posted the one with a (crow?) sitting on the same tree to give you an idea of size. Unfortunately I missed the shot of it flying away but it looked a sort of light chestnut colour and flew down away from me. Also had 8 longtailed tits (I think) this morning.
