Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.
Southern Cassowary
Produces very deep, booming rumbles and low-frequency calls below 20 Hz (infrasound), felt more than heard. Also gives loud bellowing grunts audible up to 1 km away.
Geographic Range & Migration

Massive shoe-shaped bill, one of the largest of any bird — pale yellowish-grey with darker markings
Southern Cassowary
Glossy black hair-like plumage. Brilliant blue and red bare skin on the head and neck. A large bony casque crowns the head. Vestigial wings with no flight feathers.
Long, laterally compressed, dark grey bill
About These Birds
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
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.
