Sprawk or Kestrel?

was sitting having my 1st cuppa of the day ...choccie biscuits melting in the glorious sun..camera still in the bag..then this bird was flying high over the garden back and forth ...i tried to resist picking up the camera lol but I thought i saw a kestrel pass over a few days ago and got excited that it may have come back.

Sorry not the best pics as camera was on the wrong settings!!
