Wildlife photography lucky moments

Most of the time in wildlife photography to get good shots it takes a lot of planning and investing lots of your time, other times it's just look. This was one of those lucky moments.
I was having a walk around my local nature reserve and as I approached a nest box a pair of Blue Tits weren't happy, at first I thought they were just warning me off but then realised it was a Stoat that the Blue Tits were trying to warn off. Sadly I think it was too late for the Blue Tit chicks. I managed to grab a few shots of the Stoat as it exited the nest box. Not so lucky for the Blue Tits.
