Abstract

The Smooth-coated Otter Lutrogale perspicillata has not previously been documented from Bannerghatta National Park (BNP), southern India and this study confirms its presence from the landscape. A 10-day reconnaissance survey (from 17–26 October 2024) was conducted around the Chikkondanahalli Reservoir, which is located between BNP and the village of Chikkondanahalli (Karnataka) utilizing perimeter walks and community interviews. We gathered data and signs of otter presence and activity, such as spraints, tracks, and feeding remains. On the seventh day of the survey, a direct observation of a group of four otters was made, marking the first recorded sighting in the park. Additional evidence, including fresh spraints and track marks, confirmed otter presence. However, the survey also identified several anthropogenic threats, such as fishing, cattle grazing, and pollution, which may impact the quality of otter habitats and their long-term survival in the area. The results suggest that otters may use reservoirs like Chikkondanahalli as an important habitat with potential movement between water bodies. These findings highlight the need for further research to understand otter movement patterns and habitat preferences in the BNP landscape.
