nature has its own ways, but honestly its rather rare and IMO< more of a deal in area's with lower bear numbers.
I live in a HIGH bear number area, I have seen boars and mothers with cubs in my food plots COUNTLESS times, hundreds and NEVER once seen a male go after a cub, and seen then as close at 5 ft from each other and NOT an issue
I have thousands of bear encounters, been a big part of working with bears off and on thru out the past 25+ yrs!

YES it can happen, and yes it does happen, but honestly, its NOT the norm

I GUESS< is this on that video,
a MALE bear will call FOOD its FOOD, a female came in, male wasn't planning to give up its place at the table, , mother stood her ground a LITTLE while cubs tree'd
sadly, ONE cub, went up a tree close to the bait pile?
Male came back, seen it, and well, went after it, a combo and bad luck for the little sucker
up wrong tree, and a male under it over food it THINKS is his!


lower bear numbers lead to more competition, and less chances to breed, so, a male will do what it can to get to sow its oats when the chances are more rare!

Last week I had a female with 2 cubs and a 500+ lb male feeding in a clover plot, for over 2 hrs, less then 10 yards from each other
neither paid a lick of attention to each other and both went there separate ways when they had enough!

been seeing these two together like this ALL spring too!
and many springs in the past, same like results??
BUT lots of food here and lots of bears too, I've had 10 different bears in my back yard this spring so far,(21 last yr)
I keep track when I can!

as for the video??
Honestly, its rather a RARE video to capture on a trail cam, you DON"T see that often on trail cam's
so
As for OP, sharing it??
its fine in my eye's,
BUT< I could do without the hype at the front of the video,BOLD words and such ,
to try and make it more SHOCK valued though>?
its just nature doing its thing!
