Borneo is believed to contain important populations of sun bear, which has become extinct or rare in other parts of its range and there are no reliable estimates of sun bear populations nor of population trends.
This species is the world’s smallest bear.
These bears have very long claws and a long tongue for breaking into termite mounds and bees nests for the honey. Predominantly solitary, these bears are forest dependant. OuTrop is working on analysing the many photos we have of bears to obtain a population estimate for Sabangau.
There are few reliable estimates of sun bear populations in peat-swamp forest and only limited data on their behavioural ecology. Therefore, our research provides important insights into their ecology in this habitat. We have captured 367 photos, mostly during the day!
They mainly feed on fruit and a range of invertebrates, particularly termites, ants and nesting bees. Our records suggest that sun bears have a patchy distribution in time and space, and their presence in any one part of the forest may be linked to fruit availability. Mothers and cubs have been photographed in September, October, December and January, suggesting seasonal breeding.
