Until a few years ago hardly anyone had heard of the yellow chat on the Kakadu floodplains. National Park staff had so many other species to worry about
and none of the local birdwatchers took a special interest in it. At least this is what Gill Ainsworth found during her PhD on the social value of
Australia’s threatened birds.
When artist Chips Mackinolty heard Gill’s story, he wondered how he could help raise the bird’s profile. After discussions with Gill, Chips unveiled his contribution to the chat’s conservation at the opening of an exhibition on birds and art at Charles Darwin University.
The metre-square print, based on a photo of a male chat by local birdwatcher Micha Jackson, will be sold to support Indigenous involvement in chat research and to purchase tracking devices.
Chips was not the only person to listen to Gill’s appeals. Others were becoming aware of the scarcity of chats which, by 2014, were known reliably from only one site supporting 27 birds. As a result, the chats were among the 20 highest priority birds listed in the National Threatened Species Strategy and NESP funds are being deployed to support new PhD student Robin Leppitt.
“The Alligator Rivers Yellow Chat is critically understudied, despite the fact it was listed as endangered more than a decade ago,” says Robin.
“Through extensive survey and study, I plan to greatly increase the ecological knowledge of the subspecies to aid in its ongoing conservation.”
The park is also taking great interest in the birds and has been offering Robin assistance to begin his research.
A key component to the work will be Indigenous management of the floodplains. One theory is that a lack of traditional burning has reduced the patchiness of the grasslands so big areas are now covered by only a few plant species. An early part of the work will be discussions with traditional owners of how best to manage the chat’s habitat.
Other elements of the research will be surveys to find more birds and understand more fully their ecological requirements and studies to see how feral pigs affect the chat’s habitat.

New Hub research has quantified the extent of predation by cats on Australia’s birds and identified the species and types of birds most vulnerable to cats. The team found that cats kill over 1 million birds per day in Australia. The total is made up of an estimated 316 million birds killed by feral cats and 61 million killed by pet cats each year.
Sound recorders have been installed across farm land in south-western Victoria and on Kangaroo Island in research to help threatened glossy black-cockatoos and south-eastern red-tailed black-cockatoos, by learning more about their breeding.
As cats and foxes have spread across Australia, islands have prevented the extinctions of several mammals like the boodie. Associate Professor Sarah Legge discusses the importance of safe havens and also summarizes the highlights of a recent 'safe-haven' symposium held at the International Mammalogy Congress in Perth.
The TSR Hub is one of six National Environmental Science Programme hubs and each is making its own important contribution to the national effort to recover our threatened species. Hub Director Brendan Wintle takes a look beyond the TSR Hub to highlight the good work being done on threatened species by our sister hubs.
On sub-Antarctic Macquarie Island a multi-million dollar eradication program removed cats in 2000 and rabbits, rats and mice in 2013. In the aftermath of this effort, beautiful things are emerging. Dr Justine Shaw is leading a TSR Hub project to learn from this experience and monitor how ecosystems respond.
