The black-footed albatross is a small member of the albatross family (while still large compared to most other seabirds) that has almost all black plumage. Some adults show white undertail coverts, and all adults have white markings around the base of the beak and below the eye. As the birds age they acquire more white at the base of the beak. Its beak and feet are also all dark. They have only the one plumage. They measure 68 to 74 cm (27–29 in), have a wingspan of 190 to 220 cm (6.2–7.2 ft), and weigh 2.6–4.3 kg (5.7–9.5 lb). Males, at an average weight of 3.4 kg (7.5 lb) are larger than females, at an average of 3 kg (6.6 lb). The specific epithet of nigripes is derived from two Latin words, niger meaning "black", and pes meaning "foot". Learn more about Black-Footed Albatross
