Watch a Hiker in Yellowstone Have a Rare Encounter with a Red Fox Amy Trautmann shared this video via the KTXS Television Facebook page. Get our free mobile app The National Park Service website explains why you won't have a red fox encounter like this very often: Foxes are not often seen because they are nocturnal, usually forage alone, and travel along edges of meadows and forests. During winter, foxes may increase their activity around dawn and dusk, and even sometimes in broad daylight. That last part is key. This hiker just happened to be at the right place at the right time. Due to the fact that coyotes, wolves and mountain lions are natural enemies of the red fox, it's no surprise most of their activity happens at night.
