Naturally low productivity, combined with changes in climate and habitat conditions and certain fishing practices, make these seabirds highly vulnerable.

Until recently scientists recognised 14 different species of albatrosses, but new research using DNA technology has confirmed as many as 24.

Thirteen varieties breed in the New Zealand region – more than anywhere else in the world. Several are extremely rare, like the Antipodean albatross which breed in the sub Antarctic Island of Antipodes.
