Three more native birds listed as critically endangered
17 April 2009
The status of three native birds has worsened, joining New Zealand's 22 most endangered birds listed in the 2008 New Zealand Threat Classification System.
The new listing for grey duck Anas superciliosa superciliosa (top left) has worsened from 'nationally endangered' to 'nationally critical'. The grey duck population is diminishing because of hybridisation with non-indigenous mallard duck Anas platyrhynchos platyrhynchos.
The status of the Eastern rockhopper penguin Eudyptes chrysocome filholi (left 2nd down) has moved one step up from 'nationally endangered' to 'nationally critical'.
The grey-headed mollymawk Thalassarche chrysostoma (left 3rd down), jumped from 'serious decline' in 2005, to 'nationally endangered', and now 'nationally critical'.
It is found on Campbell Island in New Zealand's subantarctic ocean, and another seven island locations in the Southern Ocean.
The grey-headed mollymawk is the only species listed as 'nationally critical', of the eleven albatross or mollymawk (Diomedeidae) species that breed in New Zealand. It is 'vulnerable' on the 2008 IUCN Red List of Threatened Species.
The IUCN Red List lists four 'critically endangered' Diomedeidae birds, including the Chatham Island mollymawk Thalassarche eremita.
The New Zealand storm-petrel Oceanites maorianis (left bottom) is currently listed in the 'data deficient' category. It was miraculously rediscovered in 2003 off the Coromandel Peninsula, after only being known from three museum specimens collected more than 150 years ago.
The New Zealand storm-petrel is listed as 'critically endangered' on the IUCN Red List of Threatened Species.
There have also been New Zealand storm-petrel sightings off Little Barrier Island in the Hauraki Gulf, and three birds were banded and fitted with transmitters in 2006 near the Hen and Chickens Islands, but their breeding location has not yet been found.
