About These Birds
Tristan Albatross
Tristan Albatross, 100–110 cm, wingspan 250–300 cm, breeds only on Gough Island in the South Atlantic — one of the world's most isolated islands. Critically Endangered; mouse predation on eggs and chicks is causing severe decline. Pelagic across the South Atlantic; piscivore and squid feeder.
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.
