Size Comparison
Habitat Comparison
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Southern Cassowary
Tropical rainforests, mangroves, and adjacent habitat in New Guinea and northeastern Australia.
Song & Call Comparison
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
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
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.
Southern Cassowary
New Guinea, nearby islands, and northeastern Queensland, Australia.

Enormously powerful, conical, pale bill capable of cracking cherry and olive stones
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
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
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.
