This deer was able to approach on her own terms, and in her own time, and it was choice of the deer to come closer. Over a prolonged period, a certain amount of trust was earned. Even in such cases, wild animals will often learn that humans provide food, and this can place them at risk if they approach the wrong humans. But this area is very isolated and very well protected. The deer here will never be at risk from humans. It is one of the few places where such an interaction can be enjoyed without negative consequences. Spending an afternoon in the presence of such a peaceful creature is unforgettable.
