Wedge-tailed eagle

Current status

The Tasmanian wedge-tailed eagle (Aquila audax fleayi) is an endemic subspecies and is listed as endangered under the Tasmanian Threatened Species Protection Act 1995. It is included in the Federal list as a critically endangered subspecies.

Why is it a threatened species here in Tasmania?

The wedge-tailed eagle is listed as endangered in Tasmania for several reasons. Firstly, the number of breeding pairs and the breeding success rate is quite low. Secondly death from unnatural causes remains high.

Nesting sites of these birds are recorded and collated onto a map revealing about 400 territories exist in Tasmania, although not all territories have successfully breeding pairs. Each pair usually lays one egg per year. Less than half of the territories produce a chick.

Changing attitudes

Those chicks that make it to fledgling stage still have to survive to adulthood. Juvenile birds are most at risk. They are still learning to hunt for themselves and are more likely to scavenge on dead lambs. Although attitudes are changing and it is recognised that lambing losses to eagles are relatively small, and usually involve sick lambs, wedge-tailed eagles are still being illegally shot and poisoned. Some farmers have developed more educated ways to deal with eagles during lambing, such as throwing the juveniles a few dead rabbits at this time.

What is being done?

The Tasmanian wedge-tailed eagle has been subject to Recovery Plans since 1992. Actions have included increasing public awareness of the wedge-tailed eagle's plight, educating the public about the eagle's importance and consulting with farmers to protect nest sites and reduce disturbances near nests during breeding.

Wedge-tailed eagles are shy breeders, which means they may desert their nests if disturbed. By encouraging foresters and other land managers to retain at least 10 hectares of bush around nest sites more nests will remain active. These kinds of actions are being included in Forest Practices Plans as a result of Tasmania's Forest Practices Code.

Learning about the importance of wedge-tailed eagles and dispelling the myths of an eagle's diet has encouraged farmers to change their attitudes about these birds. Unfortunately the birds are still at risk from vandals, shooters who just like to shoot them because they are an easy target. Hopefully this attitude too can be changed.
