I agree completely. This reminds me of the deer dropping the string thread, every time where I hunt(yes our bows are quiet). Heck I think they even duck the trigger on a rifle.

As far as suburban deer go, I USED to have some come into my backyard to eat corn I' d throw out. I could watch them through the blinds on the windows, but they wouldn' t tolerate an open blind or quick flick of the blind material. If they saw either they' d split pronto.
