What’s going to it take to save lots of the regent honeyeater from extinction?


New analysis from The Australian Nationwide College (ANU) reveals until conservation actions are urgently stepped up, one in every of our most stunning songbirds, the regent honeyeater, will likely be extinct inside 20 years.

The brand new research reveals present, already intensive, conservation efforts are usually not adequate, and an enormous redoubling of effort is required if we’re to save lots of these birds from extinction.

“The regent honeyeater inhabitants has been decimated by the lack of over 90 per cent of their most well-liked woodland habitats,” lead writer Professor Rob Heinsohn from ANU mentioned.

“Lower than 80 years in the past, it was one of the generally encountered species, starting from Adelaide to Rockhampton. Now it’s on monitor to comply with the dodo into extinction.”

In the present day there are fewer than 300 regent honeyeaters left, making it one in every of our rarest chook species. Habitat loss has pressured them to compete with bigger species for remaining habitat.

The ANU crew commenced a large-scale undertaking in 2015 to higher perceive the regent honeyeater inhabitants decline, however discovered they’re an exceptionally tough chook to review within the wild. As nomads, they wander lengthy distances seeking nectar. After 6 years of intensive fieldwork, the crew found that the birds’ breeding success has declined as a consequence of predation on the nest by species comparable to pied currawongs, noisy miners and possums.

Of their new publication the crew constructed inhabitants fashions utilising all out there information to foretell what’s going to occur to the wild inhabitants.

“Our fashions present that present conservation efforts have offered important life assist for the regent honeyeaters, however don’t go far sufficient,” co-author Dr Ross Crates mentioned.

“We have been capable of isolate the three key conservation priorities essential to safe the birds’ future.”

First, the fashions present nest success charges of each wild and launched zoo-bred birds should almost double. This requires defending nests from predation.

?Second, the variety of zoo-bred birds launched into the Blue Mountains should enhance and be sustained for not less than 20 years alongside nest safety. Taronga Conservation Society have been breeding the birds in captivity and are working onerous to extend the numbers for launch into the wild.

Third, the fashions stress that the regent honeyeater inhabitants can solely be secured into the long run if extra habitat could be protected and restored.

“With out extra habitat, reintroductions and nest safety efforts will likely be futile, as a result of the flock sizes won’t ever attain the important mass wanted for the birds to breed safely with out our safety,” Professor Heinsohn mentioned.

“Our research offers each hope and a dire warning — we are able to save these birds, however it can take plenty of effort and assets over a very long time to tug it off.”

The analysis is revealed in Organic Conservation. It was co-authored by members of the Regent Honeyeater Restoration crew together with Birdlife Australia and Taronga Conservation Society.
