Unusual visitor

One evening recently after SWMBO had gone out to bellringing I thought I heard a noise from the lounge. Thinking she had come back for something I went down to see her and discovered a different type of bird.
Here it is sitting inside the patio doors on the carpet, wondering what had happened.

Poppy then appeared and gave its tail a very gentle tap before backing off.

I let the bird (sparrowhawk?) out and resumed what I was doing on the computer. About half an hour later when I returned to the lounge I found what the bird had chased in!
