One day last week I was taking a break at work and decided to go out of the back of our building where there is a large line of Poplars and a steep bramble bank along the fence lines. I was joined by a colleague, Steve Myleham who proceeded to drop bits of apple over the fence. He explained that there were up to four 'mice' that he was feeding. Got some images of one with the iPhone and the long tail and short ears suggested that they were Bank Voles.
I joined him today with the RX100 and though the light was poor managed to get a few images as one dashed out to grab the apple.
