Drone captures stunning footage of a giant reindeer 'cyclone' in the Arctic Circle

Breathtaking drone video taken in the Arctic Circle captured a spellbinding reindeer'cyclone.' When threatened, reindeer will begin to stampede in a circle, making it hard for a predator to find an individual target. In the clip, the herd's fawns and does are in the middle of the swirl with the bucks running around them in a protective'dance.' The deer stampede was captured by a photographer last week in Murmansk, Russia, right before a veterinarian was about to give the herd its anthrax vaccinations. Such behavior has been observed in dolphins, bison and even elephants, but the aerial view--coupled with the herd's speed and size--makes for a truly hypnotic visual.
