Ficus microcarpa growing on top of a dead coconut palm trunk, Pulau Maratua, East Kalimantan. How does Ficus microcarpa establish in such unusual locations ?
Here is the obvious answer ! Glossy Starlings.
Another important disperser of Ficus microcarpa fig seeds on Pulau Maratua  are Pink-necked Green Pigeons. This is a male of the endemic Maratua race of the Pink-necked Green Pigeon.        F. microcarpa figs are small enough to be swallowed whole by Pink-necked Green Pigeons. Green Pigeons are normally seed predators of fig seeds but a few seeds may pass through their guts intact.
