Size Comparison
Habitat Comparison
Demoiselle Crane
Dry grasslands, savannas, and semi-desert. Nests on the ground in open country, often near water. Winters in agricultural fields.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Song & Call Comparison
Demoiselle Crane
A high-pitched, bugling 'karr-r-r' in flight. Also gives softer clucking and purring contact calls. Migrating flocks produce a continuous musical babbling audible from great distance.
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
Demoiselle Crane
Central Eurasia from the Black Sea to Mongolia and northeastern China. Winters in India and sub-Saharan Africa.
Northern Fulmar
North Atlantic and North Pacific oceans. Breeds from the Arctic south to Britain, France, and New England.

About These Birds
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
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.
