Freshwater marshes, bogs, and wet grasslands for breeding. Winters in coastal mudflats, estuaries, and rice paddies.
Wandering Albatross
Open ocean of the Southern Hemisphere. Breeds on remote sub-Antarctic islands. Spends years at sea between breeding attempts.
Song & Call Comparison
Red-crowned Crane
Spectacular unison 'bugling' call: a clear, resonant, far-carrying trumpet 'kru-ru-ru' given by paired birds simultaneously. Among the most majestic bird calls in Asia.
Wandering Albatross
At nesting colonies emits a loud braying 'waaah' and guttural grunts. Silent at sea for most of the year. Courtship involves ritualized mutual bill-clapping and moaning calls.

About These Birds
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
Wandering Albatross
The wandering albatross has the largest wingspan of any living bird, reaching up to 3.5 meters. These oceanic nomads can circumnavigate the globe, covering over 120,000 km per year using dynamic soaring with minimal wing flapping. Pairs mate for life and may live over 60 years.
