The Sunda Clouded Leopard Neofelis diardi is the apex predator on the island of Borneo, yet little is known of its ecology.  We document the length of residency of male Sunda Clouded Leopards in Central Kalimantan, Indonesian Borneo.  Over 10 years, camera trap data have been obtained in the Sebangau peat swamp forest in a study area of ~ 105km2.  We identified 11 individuals (eight males, one female, and two with unknown sex), from 152 notionally independent photographs.  On average, males remained in the study area for 39.3 months (SE 8.3), or 3.3 years (SE 0.7), ranging from less than a month of residency up to 71 months.  Females were infrequently recorded, possibly as a result of human disturbance and/or high male densities.  Our results reveal that even a 10-year dataset is inadequate to answer some basic ecological questions, emphasising the importance of long-term monitoring of this species.
