In a startling discovery that could rewrite the narrative of wildlife in India, two melanistic leopards were captured on camera together in the Kurseong forest division of North 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
The Kurseong region, part of the Dooars and Terai forests, has long been a hotspot for biodiversity. Over the past decade, conservationists have deployed more than 20 camera traps across the division to monitor elusive species and assess the health of the ecosystem. While melanistic (black) variants of leopards are known worldwide, sightings of two black leopards in close proximity are exceptionally rare. This event comes at a time when India’s wildlife corridors are under increasing pressure from human encroachment, making such observations both scientifically valuable and symbolically significant.
Melanism, the genetic condition that darkens an animal’s coat, is not merely a cosmetic curiosity. It can influence thermoregulation, camouflage, and even social dynamics within a species. In dense forests, a darker coat may provide a survival advantage, but the frequency of black leopards remains low, making each documented case a critical data point for researchers studying genetic diversity and population structure.
Key Developments
On 22 January, a camera trap positioned near a waterhole in the Kurseong forest division captured a frame that stunned the scientific community. The image shows two black leopards, one slightly larger, standing within a few meters of each other. The Forest Department’s Director of Forest Operations, DFO Devesh Pandey, confirmed that the pair appear to be siblings, based on their similar body proportions and the presence of a juvenile in the frame.
“This is a unique moment,” said Pandey. “We have never seen two black leopards together in the Indian wild. The camera footage suggests they are related, possibly a mother and her cubs or two brothers. We will continue to monitor them to learn more about their behavior and lineage.”
In addition to the black leopards, the Kurseong camera network has previously recorded other melanistic species, including a black barking deer, a black tarantula, and a civet cat with black stripes. These findings hint at a broader pattern of melanism within the region’s fauna, prompting questions about genetic isolation and habitat connectivity.
- Camera Network Expansion: Over 20 traps are now active, covering 150 square kilometers of forest.
- Genetic Sampling: The Forest Department plans to collect hair and scat samples from the black leopards for DNA analysis.
- Public Awareness: The footage has been shared on social media platforms, sparking widespread interest and calls for conservation action.
Impact Analysis
For students and researchers, the discovery offers a rare opportunity to study melanism in situ. The presence of two black leopards in close proximity suggests a potential increase in the frequency of the melanistic allele within the local population. This could have implications for genetic diversity, as isolated gene pools may experience reduced variability, affecting resilience to disease and environmental change.
From a conservation perspective, the event underscores the importance of maintaining wildlife corridors. The Kurseong forest division sits between the larger Dooars and the Himalayan foothills, acting as a bridge for species movement. Fragmentation of these corridors could lead to genetic bottlenecks, increasing the prevalence of rare traits like melanism but also reducing overall population health.
For local communities, the footage has heightened awareness of the region’s wildlife. Tourism operators are already considering guided wildlife tours that focus on the unique fauna of Kurseong, potentially boosting the local economy while promoting conservation education.
Expert Insights/Tips
Dr. Uma Ramakrishnan, a molecular ecologist at the National Centre for Biological Sciences, explains the genetic underpinnings of melanism. “The melanistic phenotype in leopards is caused by mutations in the ASIP gene,” she says. “For an individual to be black, it must inherit two copies of the mutation, one from each parent. The fact that we see two black leopards together suggests that the mutation is present in both parents, indicating a localized increase in its frequency.”
She adds that studying the genetic makeup of these leopards can reveal whether the melanism is due to a single mutation event or multiple independent mutations. “If the mutation is shared, it points to a common ancestor and possibly a small, isolated population,” she notes.
For students interested in wildlife biology, Dr. Ramakrishnan recommends the following practical steps:
- Participate in fieldwork with local forest departments to learn camera trap deployment.
- Engage in genetic sampling projects to understand population genetics.
- Collaborate with conservation NGOs to develop community outreach programs.
Conservationists also advise that any increase in public interest should be managed responsibly. “We must ensure that tourism does not disturb the animals,” says Pandey. “Guided tours should be limited in number and conducted by trained personnel.”
Looking Ahead
The Forest Department has outlined a multi‑phase plan to build on this discovery. Phase one involves detailed genetic analysis of the black leopards and their relatives. Phase two will focus on expanding the camera network to cover adjacent forest patches, aiming to map the distribution of melanistic individuals across the region.
In the long term, the data gathered could inform broader conservation strategies for the entire Indian subcontinent. By understanding how genetic traits like melanism spread and persist, wildlife managers can better predict how populations will respond to habitat fragmentation, climate change, and human pressures.
Moreover, the Kurseong case may serve as a model for citizen science initiatives. Local schools and universities are encouraged to involve students in monitoring projects, fostering a new generation of conservationists who are both scientifically trained and socially engaged.
As the scientific community digests the implications of this rare sighting, the broader public remains captivated. The black leopards of Kurseong have become a symbol of the hidden wonders that still exist in India’s forests, reminding us that even in an age of rapid development, nature continues to surprise and inspire.
