There's one on Youtube somewhere. Also, the How to Hunt (.com) app for BT hunting has a short video of a buck grunting as he passes the camera. Neither of these are worth spending a lot of time searching (or paying) for. In each, if I remember correctly (which I may not

) the grunts are a single burst of a half-second long sound. Presumably, they would be longer and/or louder if engaged in a fight or tending a doe. Maybe not.
