These footprints belong to one of the biggest land animals in Australia, the cassowary, a flightless bird that's almost as tall as a person. Its cloth wouldn't look at a place on a dinosaur 1. And its kick is so violent that the cassowary is said to be the world's most dangerous bird. A parent is particularly dangerous when rearing a chick.In fact, the cassowary is shy and is rarely seen in the wild, but it's a key animal here. It feeds on the fruits of rain forest trees and shrubs 2. It's one of the few animals that spread their seeds. The seeds of many forest trees can't geminate without the animal's life, the cassowary. As the forest is directly link to the reef by regulating sediments 3 entering the lagoon 4, the cassowary contributes to the health of the reef itself.
