Hello,
welcome to birdforum from me, too!
Do you have more pictures?
First jizz look is: it is either a Sparrowhawk or a Goshawak, but after downloading and enlarging the picture, I realized that heavy artefacts might well changes jizz and features.
I get a strange feeling from the appearant bulb at the forehead and the strong contrasting whitish cheek. But thats the point: what is real and what is an artefact here? If forced, my bet would be on a Sparrowhawk, but with many ??? No offense as always!
I hope for more pictures and comments!
edit: I just realized, that I am surely biased by the post of the bird. Sparrowhawks regularly rests on such buildings like here, Goshawks and Common Buzzards not (rough rule, but so many times true)
