RE: The "growl"
I have heard fawns bleat when they lose sight of their mother. I actually had a doe following me once when I used a fawn bawl in August. She was within 10 yards of us and when we would walk away she followed 10 yards behind.
My buck that I shot this year, my biggest to date, fell thanks to the Can. He was heading away from me, but I got him to turn onto a trail that brought him within shooting distance.
I've also heard tending grunts and chasing grunts in the woods, but have yet to hear a "growl" or "roar." My buddy heard a snort wheeze for the first time last year right before a buck mounted a doe. Pretty cool.
