Four more Australian birds have edged sufficiently close to extinction to be placed in the highest threat category, according to a new book by Birds Australia, CSIRO Publishing and Charles Darwin University.
The Grey-headed Albatross, the Western Ground Parrot, the Regent Honeyeater and the Norfolk Island Tasman Parakeet have been added to the critically endangered list. Furthermore, the report finds a total of 39 species or sub-species (taxa) are more threatened now than they were a decade ago. A much smaller number, seven taxa, will be downlisted as a result of conservation action that has improved their prospects.
There are now 234 Australian birds listed as either extinct, threatened with extinction ,or near threatened.
