Deer o deer

Mrs K and  I took a drive out today to Knole deer park and wandered around for a couple of hours. It’s probably the time of year, but the deer were few and far between and not a lot of images were forthcoming. We moved onto Sevenoaks Wildlife Reserve and had a stroll. In extras I have posted an image which isn’t the best, but I was hoping a clever person could tell me what it is.
