Size Comparison
Habitat Comparison
Atlantic Puffin
Breeds on grassy cliff tops and offshore islands. Spends winter entirely at sea in the North Atlantic.
Southern Cassowary
Tropical rainforests, mangroves, and adjacent habitat in New Guinea and northeastern Australia.
Song & Call Comparison
Atlantic Puffin
At burrow gives a low, moaning 'arr-arr-arr' growl. Silent at sea. At breeding colonies produces a series of grunting croaks. Chicks give soft peeping calls.
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
Atlantic Puffin
North Atlantic from eastern Canada and northeastern United States to Iceland, Norway, and northwest Russia.
Southern Cassowary
New Guinea, nearby islands, and northeastern Queensland, Australia.

How to Tell Them Apart
Atlantic Puffin
Black upperparts and white underparts with a distinctive white face. In breeding season, the face brightens and colourful bill plates develop. Winter plumage is duller with a darker face.
Large, laterally compressed, triangular bill — bright orange, blue, and yellow in breeding season
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
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
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.
