Research by Bianca McBryde at the University of Sydney reveals that predation by native possums on the eggs of the critically endangered regent honeyeater could increase its extinction risk by 35% in the next 20 years. With fewer than 250 regent honeyeaters remaining, urgent measures are being explored to protect their nests and bolster their population.
- 01Regent honeyeaters are critically endangered, with fewer than 250 left in the wild.
- 02Egg predation by possums could raise extinction risk by 35% within 20 years.

The regent honeyeater, a critically endangered bird species in Australia, faces severe threats from egg predation by native possums. Research conducted by Bianca McBryde at the University of Sydney indicates that even infrequent raids on their nests can significantly increase the risk of extinction, with a potential 35% rise in risk over the next 20 years. Currently, fewer than 250 regent honeyeaters remain, concentrated in three locations around the Blue Mountains in New South Wales. Their population has dwindled due to habitat loss and changes in flocking behavior, making them more vulnerable to predation. Conservationists, including BirdLife Australia and the Taronga Conservation Society, are exploring various strategies to protect the nests, such as tree collars and ultrasonic deterrents. Additionally, captive breeding programs are employing song tutoring to help young regent honeyeaters learn their natural calls, enhancing their chances of mating upon release. As the situation becomes increasingly urgent, immediate action is required to prevent the extinction of this uniquely Australian bird.
