This is 99% invisible. I'm Roman Mars.

Back in February of 2012, Miguel Ordinana went on a hike in Los Angeles's famous Griffith Park. The trail he took led him to a hill that

looks out over the Hollywood Bowl and the Ford Amphitheatre.

It was a little my favorite spots to collect data from because I would get these really beautiful photos of animals because I had this beautiful view of the sky and LA.

Miguel is a wildlife biologist who studies animals inside the city of Los Angeles.

As a kid, he and his mom lived in a duplex in Los Phyllis on the south side of Griffith Park.

That's producer, Roxandra Guidi.

On his hike, Miguel walked through canyons of dark green chaparral,

collecting footage from a set of motion activated trail cameras. He used the trail cams as part of his research for the U.S. Forest Service,

monitoring the animals that called the park home. When he got back to his office,

Miguel started sorting through the images.

Usually what my brain kind of gets used to is seeing a bunch of like empty photos

because grass often triggers my camera or a bunch of deer and rabbit

photos. Every now and then his cameras would pick up other animals too like

coyotes. Maybe even a gray fox if I'm lucky because I just learned that great foxes were in the park as well.

But this time around he didn't see any coyotes or foxes.

Instead he saw something even more. He didn't see any coyotes or foxes.

Instead he saw something even more extraordinary.

All of a sudden I get this big puma butt on my computer screen

and I'm just blown away.

I literally jump out of my seat.

A Puma, but.
