“As we stood outside the den we could hear the cub and smell the cats but not see anything inside the den,” said Panthera scientist Orjan Johansson. He and colleagues acted quickly, taping a camera to their antenna pole and extending it over the ledge blocking the den entrance. The footage captured shows a female leopard looking up at the camera, keeping a protective paw over her cub.
At the second den—a narrow crack in a cliff wall—the scientists discovered that the mother was away hunting, leaving her two male cubs unattended, seen below. “This was an unprecedented opportunity,” said Rutherford. “We wanted to be as careful as possible and only take the most pressing data.” The team quickly weighed, measured, photographed and collected hair samples from the cubs, which allowed genetic testing that confirmed sex and other information. More pictures of the cubs are available at Panthera’s photo gallery.
