You're not likely to see a mountain lion in Point Reyes National Seashore -- and you might not want to. But cameras hidden around the park have been snapping photos and recording video of the animals for years, and on Saturday the Marin Independent Journal posted these three videos of a prowling mountain lion, a shy mountain beaver and playful weasels. (The videos play one after another in this window.)
The cameras use infrared motion sensors to switch on when animals pass by. The images help biologists at the park keep track of various populations living there.
