Abstract
Abstract Understanding the predator–prey relationship is essential for implementing effective conservation management practices on threatened species. Leopard is a threatened apex mammalian predator that plays a crucial role in ecosystem functions in India’s tropical forest. We assessed the diet and activity pattern of leopards in relation to their prey using diet analysis and camera trapping data from Similipal Tiger Reserve, eastern India. Our results indicated that leopard prefers medium-sized prey such as wild pig, common langur and barking deer represented 60% of the total biomass consumed collectively. Results of 6413 camera trap night in 187 locations revealed that leopards showed cathemeral activity pattern and exhibited positive co-occurrence pattern and significant spatial and temporal overlap with their main prey, the wild pig. However, leopards showed very low spatial and temporal overlap with the second main prey, the common langur. Leopards avoided humans and showed low spatial and temporal overlap with humans. Our findings reveal that a trade-off might drive leopard activity between consuming prey and avoiding anthropogenic disturbances like human activity.
