I believe I read that young (that is, inexperienced) female deer become so affectionate that they will approach human hunters in the wild (who I assume restrain themselves from taking such an easy shot if it is even legal to shoot females).
If the above is true, is this because deer have come to know that by and large, most humans are not threats (humans hunt a lot less and tend to even feed wild deer). Or is it even possible that a doe will approach a bear for the same reason?
I know that young mammals of various species will befriend each other -- there must be some age at which instinct kicks in or they manage to learn about predators. But presumably by the age in which a female enters heat, instinct is starting to be present and maybe even with this instinct either humans are a special case or even, as I ask, some does will approach some predators.
