How Scientists Study it in the World

Pumas are hard to study because they are primarily nocturnal, they are most active one hour before sunset to two hours before sunrise. This combined with their elusive nature makes proving they exist almost impossible. Many scientists use the capture–mark–recapture population models to estimate the density of pumas for each area.

Despite numerous sightings over the years, only a dozen were accompanied by sufficient field evidence to be confirmed by biologists. To confirm a sighting, evidence in the form of a live or dead animal, body part(s), scat, hair samples, tracks preserved in plaster, or video/photos is needed.(www.wildliferehabsanctuary.org)
