For the first time, two Florida panthers have been filmed fighting, sparring over territory in South Florida.

On a turkey hunt with his son, Andres Pis was holed up in a blind when he saw movement to his right. Sure enough, it was a young male Florida panther. Just as he began filming with his smartphone, an older male “came out of nowhere and hit him like a freight train,” Pis recalls.

What ensued was a vicious battle, with the older male gaining the upper hand. After grappling for nearly a minute, the young male ran off, though Pis thinks it’s likely that the older male later killed the youngster.

Pis, a hunting guide and land manager, recorded the incident on March 31
