Hares are not very bright, but they know a thing or two about hiding in full sight!
You ain't seen them? Well, here you are. But they're still making sure to keep out of shooting distance - be the object aimed at them a gun or, as is the case with me, merely a telephoto lens.
(I tried to move in on it by going round that hill and surprising him from the opposite direction where I would have the advantage of the winds blowing from the hare towards me. However it got wind of my manoevre, and when I arrived there, just at the top-right corner of this image, there was nothing but an empty space left where that hare sat a couple of minutes ago.)
