Say >Hello< to New Zealand’s newest bird species!

The Whenua Hou Diving Petrel was named after Whenua Hou [Codfish Island] a small island offshore the northwest coast of Stewart Island, New Zealand, where now the last remaining breeding population of this species, some 150 individuals at the most, remains.

The species did once breed on other New Zealand islands as well, including Dundas Island and Enderby Island (Auckland Islands), the Chatham Islands, South Island, and Stewart Island. It may also have bred on Macquarie Island.

The birds of that population are just now recognized as a distinct species, differing from the South Georgia Diving Petrel (Pelecanoides georgicus Murphy & Harper), with which they were until recently considered conspecific, and even consubspecific [if such a word exists] since this species was thought to be monotypic.

The Whenua Hou Diving Petrel can be distinguished from the South Georgia birds by several external features, especially by its more contrasting plumage.

Leider sind mittlerweile nahezu alle Seevögelarten mehr oder weniger stark vom Unfortunately all sea bird species are more or less threated with extinction right now, mainly because of the increasing plastic pollution of the world’s oceans.
