Mountain lions are now posing for their close-ups.

Researchers based in the Greater Yellowstone National Park area

have figured out a new way to identify these cats by using facial recognition.

And this method is proving to be a better way to monitor

these highly elusive creatures.

Mountain lions are just really, really hard to directly observe. They're just so cryptic

and secretive. And so we've had to find these non-invasive methods, they're often called,

to get information about a mountain

lion population.

That's Peter Alexander, a research biologist based in Kelly, Wyoming, who led the research

project.

One tool that researchers like Alexander are using is a camera trap.

The traps, which are about the size of a shoebox or even a coffee cup, are attached to something

that's along the animal's regular path, like a tree that the puma has territorially scraped.

When motion is detected, the trap gets triggered, resulting in a snapshot of the mountain
