Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Southern Cassowary
Tropical rainforests, mangroves, and adjacent habitat in New Guinea and northeastern Australia.
Song & Call Comparison
African Penguin
A loud, donkey-like braying 'waaah-waaah' — hence its nickname 'jackass penguin'. Also gives softer grunts and contact calls at the colony. Highly vocal on breeding beaches.
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
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Southern Cassowary
New Guinea, nearby islands, and northeastern Queensland, Australia.

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.

About These Birds
African Penguin
非洲企鹅（学名Spheniscus demersus）是非洲大陆唯一原生的企鹅物种，又称公驴企鹅，因发出类似驴叫的叫声而得名。体重2-3千克，体长60-70厘米。濒危物种（IUCN红色名录），种群数量持续下降，主要受过度捕捞、石油污染和气候变化威胁。繁殖于南非和纳米比亚沿海岛屿。
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.
