Leo 13F is around 8 years old. The leopardess owes her name, Sikhote-Alin, to employees of the Sikhote-Alin Biosphere Reserve, who became the rare wildcat’s keepers.
As she was often spotted by trail cameras off the Chinese border, Land of the Leopard researchers had reason to suspect that Leo 13F periodically crosses into China and back.
Despite having lots of trail camera images of Sikhote-Alin, researchers were nevertheless uncertain for a long time about the animal’s sex. Finally, in autumn 2016, after studying a fresh batch of photos, they were able to say for sure that this was a female leopard.
Sikhote-Alin is a very photogenic female and, unlike most of her fellow leopards, doesn’t shy away from the cameras. Sometimes, she sits in front of a camera as if posing, which makes the images particularly sharp and scenic.
