Are Grey-headed Albatrosses social?

Grey-headed Albatrosses tend to be solitary while at sea.

How fast do Grey-headed Albatrosses fly?

Grey-headed Albatrosses can fly at speeds reaching up to 127 km per hour.

What are Grey-headed Albatross birthing rituals like?

Grey-headed Albatrosses create breeding colonies across the islands of the southern Oceans like South Georgia, Islas Diego Ramirez, Kerguelen Islands, and so on.

The cone-shaped nests are built on cliffs or steep slopes with grass and mud. A single egg is laid around the middle of October. The incubation period lasts about 70 days, the incubation duties mainly performed by the male. A successful breeding pair of adults will skip the next year’s season, returning the following year after that to breed again.

The chicks fledge about 41/2  months after hatching. They will become fully pelagic (live entirely at sea) for the first 6 or 7 years of their lives before finally returning to the breeding colonies. Even so, they may not actually breed for several more years after that.

How long do Grey-headed Albatrosses live?

Grey-headed Albatrosses live about 35 years.

How many Grey-headed Albatrosses are there today?

There are an estimated 250,000 Grey-headed Albatrosses in the world (2004 numbers).

Do Grey-headed Albatrosses have any natural predators?

Grey-headed Albatrosses don’t really have any natural predators due to the remoteness of their breeding grounds. The main threat to their numbers comes from food availability; in particular how far they have to fly to get food during the breeding season.
