This is a “Reindeer Cyclone”.
A swirling mass of threatened reindeer stampeding in a circle making it impossible to target an individual. The weakest and fawns are in the middle..

Reindeer who are kept in corrals of at least 20-25 or more can also exhibit this behavior which is probably why this video has the fence.

This behavior was recorded by Vikings, who hunted reindeer.
When they faced the threat of hunters, reindeer moved together to form a cyclone around the threat.
They moved so fast in circles that it made it hard for the hunters to focus on an animal long enough to take them…

Their behavior is similar to bird murmurations; when thousands of birds usually starlings fly in hypnotic synchronized movements usually before roosting, to confuse predator birds.

I wonder how big is that enclosure as if it's small and they want to move, this would also be the way so they don't run into each other.
