I've been tracking a bachelor group of White Tail bucks for the last three summers. The one in this video from last evening is the largest of the bunch. The 7X lens on the Mavic 3 Pro, very slow flight, and some cropping make this close view possible. None of the deer were ever aware of the drone. I think this one may have caught my scent; he stared in my direction for a while, but never raised his view to the drone.
