Working on a Maine Department of Inland Fisheries and Wildlife study that tracks the movement of moose, Wes Livingston just finished tagging a calf and was setting it free when the animal decided to fight back.

The moose remained relatively calm while Livingston released the blindfold and restraints. But when the last straps came off and the moose is able to run free, it instead turns on Livingston, knocks him backwards and then pummels him with its hooves. A small video camera attached to Livingston’s chest recorded the entire encounter.

At one point, the moose acts like it’s finally going to flee, but instead turns and charges Livingston a second time. On his back and with no other way to defend himself, he crosses his arms and tries to shield the blows. Eventually he’s able radio his colleagues.

“I’m just having a hard time, uh, letting this girl loose,” he says.
