About These Birds
Northern Cassowary
A large flightless bird of lowland New Guinea with a tall orange-yellow casque, bare blue-and-red neck skin, and one long pendant wattle. Solitary and aggressive when threatened. Feeds mainly on fallen fruit, dispersing large seeds across the forest. One of the world's most powerful kickers.
Helmkasuar
Der Helmkasuar wird aufgrund seiner kräftigen Beine und der dolchartigen inneren Kralle, die bis zu 12 cm lang werden kann, oft als gefährlichster Vogel der Welt bezeichnet. Trotz dieses Rufs sind Kasuare eine ökologische Schlüsselart des Regenwalds und verbreiten die Samen von Pflanzen, die kein anderes Tier verbreiten kann. Der Zweck ihres markanten Helms wird weiterhin diskutiert.
