I’ve seen weasels (itachi) many times on my walks and when driving my car, but this was my first chance to get some photos. I was walking along a road in the countryside near my home and luckily saw the weasel before it saw/heard me. I slowly moved my camera into position and managed to get some fairly decent shots before the weasel understood that I was not in fact a strange new species of tree, and made its escape.
