A National Park Service photograph of mountain lion P22.
The mountain lion has many names, among them, puma, cougar and ghost cat. There are somewhere between 3,000 and 6,000 mountain lions in the state of California.
They're a rare species, so a sighting is a pretty thrilling event for both biologists and nature lovers. Mike Kessler followed the history of the large feline to present day for his story in Los Angeles Magazine and joins us to talk about it.
