Birdwatching - grey wagtail or origami owl?

My eyes are not as good as they used to be and this morning in wind that was not as strong as in some parts of the country, I spotted what appeared to be a grey wagtail with its tail wagging on a rock. There are lots of these beautiful birds along the River Cole. The photograph below is enlarged through the camera lens from what I could actually see.

In fact one afternoon in summer I sat on the bank for half an hour snapping lots of photographs of them. For those unfamiliar with what a grey wagtail looks like here is one of the photographs I took that day.

Most birds are shy and you have to be very quiet and careful not to disturb them. So I crept quietly round to the other side of the rock where I took this photograph. Although the bird appeared to be moving I wondered why it never flew away because I was making too much noise. By the time I was close enough to see it was paper that was causing the illusion I was rather disappointed that I had been duped. Looking more closely I noticed that the paper caught on the rock had arranged itself into the shape of an owl and the wind had caused the illusion of movement. Can you see the origami owl?

Despite that disappointment I did go on to capture a few birds before it was time to take the dogs home. The dogs get bored when I take photographs. Anyway I captured a chaffinch, a goldfinch, a dunnock and blackbird.Birmingham is teeming with wildlife.
