There are 36 species of squirrels  in Borneo of which 14 species are nocturnal flying squirrels. Of these 36 species,  Prevost’s Squirrel is the most frugivorous and the squirrel most often seen feeding on ripe figs.

The animals that eat figs can be divided into 3 categories or guilds;

(1) Seed Dispersers, eg, most birds, some fruit bats, gibbons, orangutans, sun bears and large rats  which swallow and defecate the seeds.

(2) Seed Predators which eat and digest the seeds eg, green pigeons, pheasants and small rats.

(3) Pulp Thieves which swallow the pulp but drop or regurgitate the seeds,  eg  some birds and some bats.  Although the subject has never been studied it is most likely that Prevost’s Squirrel is a pulp thief of figs but may also swallow and disperse a few seeds.
