Sparrowhawk Victim

My daughter Zoe has just got home from school.  As she was coming up to the back door to our flats she noticed a yellow-eyed, brown-speckled bird standing on top of this unfortunate pigeon.  On seeing Zoe, the yellow-eyed bird flew off and has not returned.  I suspect that  it has abandoned the kill because it is too close to the flats and would involve the risk of being cornered and unable to take off.

I showed Zoe this photo of a sparrowhawk and she said "Yes, that's what it was!".  I was surprised, as I had assumed that they only took smaller birds but, apparently, I was wrong.
