- Camera traps enabled researchers and a professional photographer to document the presence of a rare melanistic (black) leopard, confirming reports of the cat in northern Kenya.
- Five different remote camera stations, positioned near water sources and trails, recorded the young female leopard over three months.
- The case demonstrates the value of remotely placed sensors in capturing both shy, cryptic animals and rare events in nature, such as melanism, which results from genes producing a surplus of pigment in an animal’s skin or hair so that it appears black.
Sometimes, a black cat can bring good luck.
A professional photographer, together with leopard researchers from San Diego Zoo and Kenya’s Loisaba Conservancy, used camera traps to document the presence of a melanistic (black) leopard in Laikipia County in northern Kenya.
Field staff at Loisaba had received several reports of observations of a black leopard in the area in late 2017. After hearing the unconfirmed reports, the researchers set out to find it. In early 2018, they deployed eight remote cameras over a 0.5 square-kilometer (124-acre) area as part of a larger-scale exploration of the population dynamics of leopards in Loisaba and nearby Mpala conservancies.
Lead researcher Nick Pilfold of San Diego Zoo’s Institute for Conservation Research and colleagues positioned the cameras at available water sources and animal trails in these dry bushlands, leaving them on 24/7 to take repeated 15 to 30-second video clips, with a 1-second break in between. They turned the cameras in public areas on only at night.

Within the first month, the camera traps confirmed the suspected sightings of the leopard with this rare dark color morph. They recorded the subadult female leopard five times at five different camera locations.
“It is likely that black leopards have been living in Kenya all along, it is only that high-quality imagery to confirm it has been missing until now,” Pilfold told CNN.
Photographer Will Burrard-Lucas also documented the black cat, using a Camtraptions camera trap to obtain a set of dramatic, professional-quality photos. He wrote in a blog post, “As far as I know, these are the first high-quality camera trap photographs of a wild melanistic leopard ever taken in Africa.”
Melanism is a condition resulting from a gene that causes a surplus of melanin pigment in the skin or hair of an animal so that it appears black. Roughly 11 percent of leopards are thought to be melanistic, Pilfold said, but most occur in Southeast Asia, where their darker color may offer camouflage in the region’s tropical forests.
“Black leopards in Africa are extremely rare,” he added, “and prior to the observations in our published paper, the last confirmed observation was 1909 in Ethiopia.”
