Size Comparison
Habitat Comparison
Common Ostrich
Open arid and semi-arid habitats including savannas, Sahel, and dry woodlands across Africa.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Song & Call Comparison
Common Ostrich
Male produces a surprisingly deep, resonant booming roar — remarkably lion-like. Also gives whistling and hissing sounds. Females and chicks emit softer grunts and squeaks.
Northern Fulmar
A nasal, cackling 'kak-kak-kak-kak' or grunting 'uh-uh-uh' at the nest and colony. Less melodic than petrels. In flight gives occasional single nasal calls.
Geographic Range & Migration
Common Ostrich

North Atlantic and North Pacific oceans. Breeds from the Arctic south to Britain, France, and New England.

About These Birds
Common Ostrich
非洲鸵鸟（Struthio camelus）— 世界上最大的鸟，栖息于非洲草原。虽然不能飞翔，但奔跑速度可达每小时70公里，产下世界上最大的蛋。
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
