theycan't see in pitch black, no moon nightvery well but they can make out silhouettes alot better than the human eye. when there is just a small amount of moon light they can see very well, again alot better than the human eye. To cut around all this "if-this-and-if-thats" Yes they will see you in the dark, they will smell you and they will hear you. will they blow/snort at your, depends on the deer.
