Vikings hunting reindeer in Norway were once confounded by “reindeer cyclones”; a threatened herd would literally run circles around the fierce hunters, making it nearly impossible to target a single animal.

Filmmakers recently captured incredible aerial footage of one of these reindeer cyclones, which aired Feb. 13 on PBS in the documentary “Wild Way of the Vikings,” a program about Vikings and the wilderness they inhabited around A.D. 1000.

One of the documentary’s most striking scenes shows a re-enactment of a Viking hunt interspersed with real footage of reindeer herds. Reindeer were important to the Vikings for their meat, hides, antlers and bones, according to the film.

In the cyclone scene, a lone hunter (an actor playing a Viking) approaches the herd; he notches and releases an arrow. The footage that follows shows an actual herd of reindeer running in circles. As the swirling mass of bodies thunders along a circular path, an overhead camera reveals that the herd’s momentum follows a spiral shape, drawing tightly toward the cyclone’s “eye” at the center.

Faced with this spinning reindeer stampede, any predator — wolf, bear or human — would have a very tough time targeting and overpowering a single reindeer, making this a formidable defense strategy, according to a statement from PBS.

This behavior is also practiced by reindeer kept in corrals, occurring in groups of at least 20 to 25 animals, researchers wrote in a 2002 study published in the journal Rangifer. Penned reindeer formed “cyclones” and were observed to run “invariably” in a counterclockwise direction, the scientists reported.
