Abstract Surveys targeting flagship species frequently record the presence of other species, providing valuable bycatch data to fill knowledge gaps on ecology overlooked species. Using records from camera-trap surveys for tiger Panthera tigris , we model occupancy sun bear Helarctos malayanus predict its temporal change in during 2015–2019 and determine activity patterns Bukit Barisan Selatan National Park, part a UNESCO World Heritage Site Sumatra, Indonesia. We performed single-season modelling that considered unequal detection probability detection/non-detection records. found Intensive Protection Zone (i.e. priority protection area) Park was slightly higher than north Park. In Zone, estimated be 0.67 2015 increased 0.83 2019, but this increase not substantial. The exhibited cathemeral pattern. Most occurred day (46.2%), followed by night (21.2%), dusk (20.9%) dawn (11.7%). encourage collaboration amongst institutions conducting studies Sumatra examine threatened yet assess broader biodiversity benefits conservation strengthen science-based efforts.
