About These Birds
Laughing Kookaburra
The laughing kookaburra is the largest kingfisher in the world, famous for its raucous laughing call that has become an iconic sound of the Australian bush. Despite being a kingfisher, it rarely eats fish, preferring terrestrial prey. Family groups perform chorus calls at dawn and dusk to mark their territory.
Southern Cassowary
The southern cassowary is often called the most dangerous bird in the world due to its powerful legs and dagger-like inner claw that can reach 12 cm in length. Despite this reputation, cassowaries are vital rainforest keystone species, dispersing seeds of plants that no other animal can. The purpose of their distinctive casque remains debated.
