I’ve heard that sound before.

I’ve also heard them “roar”. The instance in which this occurred is an atrocity, but it boiled down to a rifle wounded buck that had it’s hind quarters broken as well as it’s shoulders..it was dragging itself along the ground and making a grunt like tone with extreme volume and duration. Like a Lions roar. The inexperienced hunter who had wounded the animal had run out of ammo, and every time I approached to try and cut the poor creature’ throat to put it out of it’s misery, it would make this roaring sound and try to get up or crawl away.[:' (] I can assure you I almost crapped myself the first time I heard that. Eventually the deer became too weak to move even his head and I finished the job with my knife.

Disgusting situation, and I damn near quit hunting because of it. I won’t ever forget the sound. [:' (] I certainly hope that “hunter” never entered the woods again.[:@] He did not seem remorseful whatsoever.[:@][:@]
