Phoebastria irrorata - also known as Galapagos Albatross
The only truly tropical albatross, the only breeding population is on Espanola island in the Galapagos Archipelago
These are medium-sized albatrosses, measuring about 86–90 cm (34–35 in) long, weighing in at 3.4 kg (7.5 lb) and having a wingspan 227 cm (7.4 ft).
The courtship of the Waved Albatross is a very elusive and spectacular sight to see, it includes: rapid bill circling and bowing, beak clacking, and an upraised bill to make a whoo hoo sound.
The eggs are laid between April and June and incubated for two months after that. The young reach adult size by December and leave the colony by January.
The partners mate until one of the partners dies.
Despite some 34,700 adult birds still occurring in 2001, their numbers have apparently started to decrease at an unknown rate more recently, probably due to longline fishing which also upsets the sex ratio (males being killed more frequently). As the current situation makes the population highly vulnerable to a catastrophic collapse to extinction, it was uplisted to Critically Endangered status in the 2007 IUCN Red List.
