(CBS 8) - The wily red fox's reappearing act near Yosemite is stunning scientists.
Biologists are very excited. It's not been since the 1920's and 1930s that red foxes have been seen in the eastern Sierra.
The first sighting came in August, then on Friday the forest service confirmed two more sightings, all done using camera traps.
In this News 8 video story, Shawn Styles explains their importance.
