About These Birds
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.
Superb Fairywren
The superb fairywren is one of Australia's most beloved and recognizable birds, with breeding males dressed in spectacular violet-blue plumage. These tiny birds live in cooperative family groups where helpers assist the breeding pair in raising young. Males pluck and present yellow flower petals to females as part of courtship.
