I some cases yes,........ but many times when a bunch of does are feeding in a field or plot and take off with no ryme or reason, most oftengives away the fact thatthe "big boy" is coming.
I can't say how many times I've been in the stand, staring at does..... and all of a sudden they all take off..........immediately my senses are heightened, and shortly thereafter ol' mossy horn comes in to nibble a little.
