Open ocean of the Southern Hemisphere. Breeds on remote sub-Antarctic islands. Spends years at sea between breeding attempts.
Song & Call Comparison

A harsh, grating 'rack-rack' or 'quarrk' in flight. Gives a variety of sharp nasal calls at the nest. Not melodic; primary vocalizations are alarm and contact calls.
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
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
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.
