Wandering AlbatrossThe Wandering albatrosses are the largest flying birds on earth, with wingspans of up to 3.5 metres. They breed on sub-Antarctic islands around Antarctica.
Note: Recently, the population of Wandering albatross has been
split into four regional species:
Birds from these different populations have similar biology, and are difficult to tell apart at sea. Therefore they are treated as one group here - "Wandering Albatross".
Breeding: Every two years - because it takes a year to complete the breeding cycle. They incubate their single egg for 11 weeks and the take a further 40 weeks to fledge their chick, which is dependent upon the parents for food over this entire period. The chick perishes if either parent is lost at sea to longlines because a single parent cannot collect enough food. Breeding Season: Egg laying - December to February; Hatching - March to April; Fledging - November to February. Colonies: South Georgia, Prince Edward, Crozet, Kerguelen, Heard, Macqueire, Campbell, Antipodes, and Auckland Islands Population: The total number of individual albatross is around 134,500. Each year around 20,682 pairs attempt to breed. Status: Antipodean, Gibson's and Wandering - "Vulnerable"; the small population of Tristan albatross are classified "Endangered". Of the eight population study sites where we have reliable data, four are declining, one very small population is now stable after a period of decline, and three are increasing. Wandering albatross are circumpolar between around 40 and 60 degrees
south latitude, although at times they will penetrate further south into
the pack ice - in the Ross Sea, as far as 70 degrees South.
