What is this bird?

I was just watching a couple of Robins in the garden when this thing flew in. I was only able to get one shot so sorry for the poor quality.
Anyway we know very little about birds, I thought it was some sort of hawk but would appreciate someone identifying it....

I was going to blip Molly

Miserable rainy day today, we got a little gardening done but that is about it for now....
