First Newborn Leopard Cub Sighting in a Tree Hole with Mother at Yala National Park, Sri Lanka

Abstract
Introduction: The Sri Lankan leopard (Panthera pardus kotiya) is a sub species of the Panthera pardus family. It inhabits a variety of island’s habitats ranging from tropical rainforests to arid zone scrublands. This report documents the rare sighting of a newborn Sri Lankan leopard cub observed with its mother in a tree hole within Yala National Park, Sri Lanka.

Results: On April 7, 2023, a female leopard and a newborn cub: estimated to be less than 10 days old, were sighted in a tree hole located approximately 15 feet above ground level. The mother leopard was observed nursing and grooming the cub, exhibiting relaxed yet vigilant behavior. The interaction was captured through high-resolution photography, capturing this rare display of maternal care and habitat use. Subsequent observations, including a follow-up sighting in 2024, indicated that the cub has continued to thrive, highlighting successful mother-cub bonding and survival.

Discussion: This sighting marks the youngest leopard cub ever documented in the Yala National Park, Sri Lanka and highlights the suitability for leopard breeding within the ecosystem. These observations contribute to understanding critical aspects of leopard maternal care and habitat requirements, which impact the cub survival during early life. Continued conservation and research in Sri Lanka’s protected areas are essential to ensure the survival of this vulnerable species and its future within the island’s ecosystems.

摘要
引言：斯里兰卡豹（Panthera pardus kotiya）是豹科（Panthera pardus）的一个亚种。其栖息地多样，从热带雨林到干旱地带的灌木丛均有分布。本报告记录了在斯里兰卡亚拉国家公园内，一次罕见的幼豹出生事件，观察到该幼豹与其母豹在一树洞中。结果：2023年4月7日，一只雌豹及其新生幼崽（估计出生不足10天）在离地面约15英尺的树洞中被发现。观察到母豹正在哺乳并梳理幼崽，表现出放松但警觉的行为。这一罕见的亲子互动通过高分辨率摄影得以捕捉，展现了母性关爱与栖息地利用的珍贵画面。后续的观察，包括2024年的再次发现，显示该幼崽持续健康成长，凸显了母子间成功的联结及幼崽的存活。讨论：这一发现标志着在斯里兰卡亚拉国家公园中记录到的最年幼的豹崽，并突显了该生态系统内豹类繁殖的适宜性。这些观察结果有助于理解豹类母性护理和栖息地需求的关键方面，这些因素对幼崽早期生活存活至关重要。在斯里兰卡保护区持续进行 conservation 和研究对于确保这一易危物种及其在岛屿生态系统中的未来生存至关重要。
