Cougars are often called the “ghosts of the forest” and Laura Prugh can attest to that. Although she has been studying them for years, she has never seen one in person. Find out how cougars hunt their prey, the techniques her team uses to study these big cats and how they benefit humans by helping to control the deer population. Dr. Mark Elbroch, an ecologist and director of the Panthera program in Washington state also joins Laura on the show. You can listen to the 27 minute BBC Tooth and Claw podcast here.
