I was walking along the bank of the Calder below North Dean Woods, Copley, on 18th May, when an object floating along with the brisk current caught my eye.

It was a male Mallard, belly up, feet in the air. It wasn’t dead, but travelling tail first with it’s feet relaxed

.
It was moving its head, looking round as it got level with me as if to say “Look what I can do” !

As I fumbled to get my camera out it nearly went out of sight. The last thing I saw of it was when it flipped over into the normal position and started paddling against the current.

I wouldn’t believe this if I hadn’t got a picture of it. It’s poor quality but it confirms what I saw. (I know it looks dead in the picture, but I had no time to switch the camera to video.)

What could have been happening?
