Roe Buck standing on his back legs

The most extraordinary performance this evening by a Buck in the field
not thirty yards from my bench seat on the hillock. At first I thought
he was trying to kill a snake, or was trying to tamp down a sleeping
area in the long grass, but then I wondered if he had been stung by a
wasp or something. He was jumping up into the air, sprung on all four
legs as if he had been given an electric shock, and then bucking up
and down. Unfortunately I only had my short range lens on the camera
so I didn't get any good shots, but this is one which will give you an
idea. He seemed completely oblivious to my presence until I stood up
to go and get a telephoto lens!
