#RegentHoneyeaters are in decline due to threats from #habitatloss and degradation. #Drought, #bushfire, competition, and now even the precariously small size of the remaining population all pose risks to the species’ survival.
Our team of #RegentHoneyeater keepers are experts in #ConservationBreeding these amazing birds. Here specialist keeper Kara Stevens explains our progress at Taronga Western Plains Zoo, Dubbo.
To get the most success from our program our scientists have looked at the life of every released bird & how they fared after release into the wild.
Our collaborative #science showed birds have highest survival when released at 1-3yo. The more time they spent in large, complex aviaries with other species also increased their breeding chances. frontiersin.org/articles/10.33…@joytripovich
Results like these help us to manage our #ConservationBreeding & design future release strategies

Taronga’s marine scientists, in collaboration with Macquarie Uni & others internationally, are investigating the effects of pulsed electric fields on #shark physiology & behavior to deliver innovative improvements in deterrents to save the lives of people & #sharks. #ScienceWeek
This @ARC_gov_au funded project builds on a previous ARC LP by this team that uncovered information on #shark vision and demonstrated the effectiveness of counter-illumination (light emitting) devices in deterring shark attacks
The new project (late 2020>) will test the effectiveness of existing & improved personal deterrents against attacks from white, bull & tiger #sharks. This should reduce fatalities by increasing device-use, while also reducing the need for indiscriminate meshing/culling programs.
Taronga scientists also manage the Australian #Shark Attack File (ASAF). This long-term database & resource provides valuable insights on incidents and the effectiveness of possible deterrents. #ScienceWeektaronga.org.au/conservation-a….
Research using ASAF data led by Laura Ryan with Taronga’s Dr David Slip, Macquarie University, DPI and UNSW scientists, generated predictive models for #shark attacks in Australian waters based on environmental conditions. . doi.org/10.3354/meps13…
This paper identified rainfall & sea surface temperature anomaly as key predictors, and is of great value in designing a potential warning system platform that can allow water users to make more informed decisions before entering the water.
As Taronga’s Research & #Conservation Coordinator, & a marine biologist specializing in #ConservationGenetics, Dr Jo Day, wears many hats – & most are waterproof! Jo’s work covers many areas & species, including the little-known Port Jackson #shark... #MarineScience#ScienceWeek
Data from GPS and accelerometer tags fitted to Taronga zoo-based Port Jackson #sharks allowed the team to identify resting & active swimming, as well as feeding behaviour.
Getting lost in the crowd can be a problem when you’re an #endangered sea lion pup. Taronga behavioural ecologist @PitcherBen & collaborators are decoding #Australian#sealion communication to understand how mothers and pups recognise each other in a busy colony #ScienceWeek
Smell is critical to recognition. Mums will smell pups they encounter while searching the colony to confirm which pup is their own offspring. Each sea lion has a unique smell and mums learn the odour of their pup sciencedirect.com/science/articl…#AnimalCommunication
Taronga is also reminding #RegentHoneyeaters how to tweet! Their song has been changing, perhaps due to small fragmented populations &reduced opportunity to learn from adults. Taronga keepers began playing songs to juvenile birds to teach them the right ones to sing. #ScienceWeek
Results are showing that #RegentHoneyeaters that were tutored to sing, either directly by adult birds or by virtual tutoring, had a better chance of surviving in the wild.
We’re now working with researchers at ANU to understand how best to teach birds to sing and why song is important to survival theguardian.com/australia-news…
The #PlainsWanderer has no living close relative, which places it top of the @EDGEofExistence list. Remnant populations of this small ground-dwelling bird are mostly in Victoria, eastern South Australia and in the western Riverina region of NSW.
Though excellently camouflaged, #PlainsWanderer are just the right size to be eaten by invasive foxes. Taronga is working with @ZoosVictoria to establish an insurance population & recently built a #ConservationBreeing facility at Taronga Western Plains Zoo #sanctuary, #Dubbo.
