I'd guess a Collared Sparrowhawk, but I'm only going from the light coloured cere and the bare legs. It's pretty hard to tell from the dark colouring in the 'photo, iceworks. If it is, and it's an adult, it should be around 300 to 400 mm in length. The Goshawks are usually a little longer. Of course if it's a juvenile it makes identification a little more difficult.
As Ron requested, more information would help.
