A couple visiting Yellowstone National Park have delivered a textbook example of how not to photograph wildlife, cornering a large bison in a parking lot to take pictures on their phones.

A video of the dangerously close encounter, shared via Instagram account TouronsOfYellowstone this week, shows the pair slowly approaching the animal from behind, seemingly unaware of the danger. After a few moments seemingly photographing the animal's backside, one of the pair draws even closer, getting within a couple of meters.
