In this unique process, fig seeds are dispersed through birds' digestive tracts, then germinate on a tree branch, where they grow as epiphytes. As their aerial roots reach the ground, they grow faster, forming more roots that eventually enclose and kill the supporting tree, creating a hollow cavity.
Strangler Figs: The Deadly Grasp
Birds facilitate seed dispersal in certain ficus species by consuming seeds and then depositing them on tree branches, allowing the seeds to sprout and grow into strangler figs.
