About These Birds
Amsterdam Albatross
Amsterdam Albatross, 100–110 cm, is Critically Endangered with fewer than 100 breeding pairs, restricted to Amsterdam Island in the southern Indian Ocean. Closely related to Antipodean Albatross. Pelagic across Indian Ocean. Threatened by longline fishing, disease, and the tiny, isolated population size.
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.
