Their bungalow in Kaladhungi was inside a dense forest in which a large variety of plants and animals found refuge. The abundance of wildlife in Nainital those days can be gauged from the fact that Jim spotted tigers and leopards within a six and a half-kilometer radius of the temple of the goddess Naini. As a result of living in such exotic and beautiful surroundings he developed a spontaneous affinity with nature.

At the tender age of ten he found himself addicted to hunting, he had shot his first leopard and would just pick up and train his gun on any wild animal he encountered in the Jungle. While his friends were overjoyed Jim vowed never to kill a beast without a reason. After he had killed a man-eater known as the Kuara of Pawalgadh in the mid thirties he gave up Shikar as a sport. There after he shot only those tigers which had turned man-eaters or cattle lifters.

Jim considered it his duty to kill such dangerous animals, a duty he carried out faithfully till his last days. He killed his last man-eater when he was well past sixty In those days the terror of Man-eaters loomed heavy on the regions of Kumaon and Garwhal and Jim was the only man who had the guts to take on and kill such bloodthirsty beasts, endowed as he was with his superlative skills required for the job he killed man-eaters in their den, in open grassland, in dense forest and on rocky slopes. Some of his most famous encounters are published in his six books of which the man-eaters of Kumaon and The Man Eating Leopard of Rudra Prayag are well renowned.

In all his years serving the cause of wildlife preservation and later deliverer of peace and tranquillity in the man eater infested regions of Kumaon and Garwhal Jim became inherent with the wildlife conservation and the Indian Government in 1956 renamed the park – Corbett National Park in honour of Jim Corbett the powerful missionary for wildlife preservation in India.
