Waved Albatross
Phoebastria irrorata
These are medium-sized albatrosses, measuring 80 to 90 cm (31 to 35 in) in length with a wingspan of 220–250 cm (7.2–8.2 ft). They range between 2.7 and 4.0 kg (6.0 and 8.8 lb) in mass, with males averaging significantly heavier than females. They are distinctive for their yellowish-cream neck and head, which contrasts with their mostly brownish bodies. Even more distinctive is the very long, bright yellow bill, which looks disproportionately large in comparison to the relatively small head and long, slender neck.
