Two black bears were reportedly found fighting "over a female" in a person's backyard.
A New Jersey homeowner was shocked when he found the wild native North American animals sizing up against each other and versing in his garden.
Corey Bale - who videoed the brawl - told NJ.com he went outside to investigate last week after a neighbour told him there was a bear behind his Frankford Township home.
But when he stepped outside, he heard a loud commotion and discovered there were actually two big bears in a brawl.
He said: "When I went out to look, I actually heard the bears' jaws hitting together as they were fighting and growling at each other."
The violent animals were covered in blood before they were broken apart and the man thinks the duo were fighting over a third female bear.
