Australian Warblers: Acanthizidae

One species of gerygone, the Lord Howe gerygone was already Extinct, no longer existing, by the beginning of the twenty-first century. The Biak gerygone is Endangered, facing a very high risk of extinction in the wild; and the Norfolk Island gerygone is Vulnerable, facing a high risk of extinction in the wild. These populations have been hurt by habitat loss as well as from the introduction of predatory mammals. In 2000, the Action Plan for Australian Birds listed a large number of this family as Threatened, in danger of extinction, or Almost Threatened, close to becoming threatened. Other threats to these populations have been extensive fires and grazing from the introduced mammals. Only the Coorong subspecies remained categorized as secure on the Australian list.
