List of critically endangered Australian birds swells
A new report on Australian birds has added four more species to the critically endangered list and found that a total of 39 species or sub-species are more threatened now than they were a decade ago. The Action Plan for Australian Birds 2010, compiled by researchers from Charles Darwin University and published today by the CSIRO, is an update on the previous report released in 2000. This 2010 report lists 27 taxa (which means species or sub-species) as Extinct, 20 as Critically Endangered, 60 as Endangered, 68 as Vulnerable and 63 as Near Threatened as at 31 December, 2010. The four taxa that that were added to the Critically Endangered list are the Grey-headed Albatross Thalassarche chrysostoma, the Western Ground Parrot Pezoporus flaviventris, the Regent Honeyeater Xanthomyza phrygia and the Norfolk Island Tasman Parakeet Cyanoramphus cookii.
