When confronted by a giant bear most people would run away as quickly as possible and head for the nearest tree (a recipe for disaster - you can't outrun a bear).
But one Swedish man doesn't play by the normal rules. Ralph Persson stood his ground, spread his arms and summoned an almighty roar - sending the brown bear running back into the woods with its tail between its legs.
Persson, who had been out training his new hunting dog in Jamtland at the time, told Hela Halsingland that he took his inspiration from birds.
"I have seen in the past how even cranes have chased bears by folding up their wings," he explained.
