In the rainforests of northeastern Queensland, Australia, the cassowary plays a vital role in the ecosystem by acting as a seed disperser for various palm species.

The process functions through the bird's diet:
* Ingestion: Cassowaries forage for fruits, which constitute the main part of their diet.1
* Dispersal: By ingesting the fruits of rainforest palms—specifically those of the genera Calamus and Linospadix—the birds transport the seeds throughout the forest, effectively spreading them as they move.2

This relationship is a critical example of how animal behavior influences the composition and regeneration of tropical forest communities.2
