Pigeon Pie

I walked into the lounge this evening and this is what I saw through the window.  I'm guessing it's a sparrow hawk because of the orange eyes, unless anyone knows better.  I don't mind pigeons being demolished, but I wish she (I think it's female) had swept up the bits and put them in the bin for me.  Unless a fox takes the rest of it I'll have to clear up in the morning.
