Owls about that then.

Looking out of our bedroom window the other evening after I disturbed the Little owl sat on the adjacent garage roof. It flew to the large black poplar at the back of the garden and balefully turned its back on me. Sneaking out I got the camera from the study and sneaked back in and very quietly opened the window. He (I know this as if you look very carefully you can see the rings on the left leg) turned round,glared at me and then carried on with his observations allowing a few photos.

Amazing pattern on back of head makes it look like its still looking at you. Wonder if this is an anti-predator device. I've found dead Little Owl predated by a Sparrowhawk locally so it may well be.
