Well that was short and sweet! LOL
Actually does will respond to fawn bleats and occasionally to doe grunts (yes does do grunt too). I've gone into heavy cover (that stuff that looks like bamboo abouit 7-8' tall) in late May / early June and just used my voice as a bleat and almost been run over by does coming in to protect their fawn. I've also had young deer under my stand in early archery season bleat several times and then trot off to a doe in the distance I didn't see. She probably answered her yearling but I didn't hear it.
