Some bears, when fatally hit, will emit a moan or bawl. What is your knowledge or experience with this?

My story: I was a fairly seasoned hunter and had been on several bear hunts with my dad, but had never shot a bear. This year I decided to give it a try, and was hiking up my favourite power line, the same place I had harvested my first moose many years before. Back then it was open clear cuts, now it is an absolute jungle of birch, aspen, alder and willow with coniferous trees trying to make a go of it. I topped a rise and saw a good bear walking across the right of way. I realised my window of opportunity was short so I quickly set up for a shot before the bear got into the thick brush. My model 99 savage in .308 was a trusted gun for me so I fired, and the bear hunched up and then ran into the jungle. This all happened very quickly.

As a mix of adrenaline and emotions flooded through me, a strange bawling sound came from the bush. Honestly, the thought fleetingly crossed my mind that I had shot a cow. I think there were three distinct howls. I gave it 20 mins and went to have a look.

To make a long story short, I started looking in the wrong place and it took me 2 hours to find the bear when it had only gone about 10 yrds. But to be fair, that bush was THICK. Visibility of 6" thick. So 2 hours of nervously stumbling around in thick rhubarb after a bear. Maybe not the smartest thing on Earth, but a guy is feeling truly alive in those scenarios.

I found the bear and enjoyed the meat and memories. Anybody else have a story to tell?
