In a startling discovery that could reshape wildlife conservation in India, two melanistic leopards were captured on camera in the dense forests of Kurseong, West Bengal. The footage, released by the Forest Department, shows the black-coated big cats side by side, a sight that experts say may be the first of its kind in the Indian wild.
Background/Context
Melanism, the genetic condition that gives animals a darker coat, is relatively rare in leopards. While the species is widespread across Asia, black leopards are usually solitary and elusive. Kurseong, part of the Dooars region, has long been a hotspot for biodiversity, but the presence of two black leopards together raises questions about genetic diversity, habitat connectivity, and the impact of human encroachment.
Over the past decade, West Bengal has intensified its wildlife monitoring efforts, deploying more than 20 camera traps across the Kurseong forest division. These devices aim to document species presence, track movements, and raise public awareness about conservation. The recent footage adds a new chapter to the region’s wildlife narrative.
Key Developments
On 22 January, a camera trap positioned near a waterhole in the Kurseong forest captured a pair of black leopards resting in the shade of a banyan tree. The image, shared by Forest Officer DFO Devesh Pandey, shows the animals in close proximity, suggesting a familial bond. “It appears they are siblings,” Pandey said. “We will continue to monitor them to learn more about their lineage and behavior.”
In addition to the leopards, the same camera has recorded other melanistic species in the area, including a black barking deer, a black tarantula, and an Asian palm civet with black stripes. These sightings hint at a possible increase in melanistic traits within the local fauna.
- Camera Deployment: 20+ traps active across Kurseong.
- First Recorded Pair: Two black leopards captured together.
- Additional Melanistic Species: Black deer, tarantula, civet.
Genetic analysis is underway. Dr. Uma Ramakrishnan, a molecular ecologist at the National Centre for Biological Sciences, explained that melanism in leopards results from a mutation in the ASIP gene. “For a leopard to be fully black, it must inherit two copies of the mutation, one from each parent,” she said. “The presence of two black leopards together suggests a higher frequency of this mutation in the local population.”
Impact Analysis
For conservationists, the discovery underscores the importance of genetic monitoring. A higher prevalence of melanism could indicate reduced genetic diversity, especially if the population is isolated. Habitat fragmentation in the Dooars, caused by expanding tea plantations and human settlements, may limit gene flow, allowing rare mutations to become more common.
Local communities stand to benefit from increased awareness. The Forest Department plans to use the footage in educational campaigns, highlighting the uniqueness of Kurseong’s wildlife and encouraging eco-tourism that supports sustainable livelihoods.
Students and researchers in wildlife biology and genetics will find the case study of black leopards Kurseong invaluable. It offers a real-world example of how environmental pressures and genetic factors intersect, providing a living laboratory for fieldwork and data collection.
Expert Insights/Tips
Dr. Ramakrishnan advises that monitoring should continue beyond camera footage. “Collecting biological samples—such as hair or scat—will allow us to perform DNA sequencing and confirm parentage,” she said. “This data can inform breeding programs and help maintain genetic health.”
For those interested in contributing to conservation efforts, the Forest Department recommends:
- Participate in citizen science initiatives by reporting wildlife sightings.
- Support local eco-tourism projects that prioritize habitat preservation.
- Advocate for stricter enforcement of wildlife protection laws in the Dooars region.
Students studying ecology can use the Kurseong case as a springboard for research projects on genetic diversity, habitat connectivity, and the effects of melanism on predator-prey dynamics.
Looking Ahead
The Forest Department plans to expand camera coverage to 35 sites by the end of the year, aiming to capture more data on black leopards Kurseong and other rare species. A comprehensive genetic study is slated for 2027, with the goal of publishing findings in a peer-reviewed journal.
Conservationists hope that the increased visibility of these black leopards will galvanize support for protecting the Kurseong forest. “If we can showcase the uniqueness of this ecosystem, we can secure funding and policy backing to preserve it for future generations,” said Pandey.
Meanwhile, researchers are exploring the possibility of a broader melanistic trend across the Eastern Himalayas. Preliminary surveys in neighboring districts have reported similar sightings, suggesting that the phenomenon may be more widespread than previously thought.
As the scientific community digests these findings, the story of the black leopards Kurseong serves as a reminder of the delicate balance between nature and human activity. It also highlights the power of technology—camera traps, genetic sequencing, and data analytics—in uncovering hidden facets of wildlife.
