Natalie Briscoe and colleagues were part of a team that has been investigating whether we can improve the functional performance of nest boxes. They wondered
what difference surface reflectance would have on the temperature inside nest boxes if the outsides of the boxes were painted in different colours.
The team tested three different coloured nest boxes (white, light-green, and dark-green) to see if the colour of the nest boxes had an effect on the internal temperature they maintain.
Their study found that light coloured boxes were the best at reflecting heat during summer and dark coloured boxes asborbed heat well in winter. Other factors including box design, placement, and the amount of shade boxes received also influenced the internal temperature of the nest boxes.
These conclusions have important implications for the use of nest boxes as a conservation tool. Conservation managers considering the implementation of nest boxes programs need to give careful consideration to design, colour, placement and shade profile of nest boxes.

We are offering an honours project looking at feral cats in two national parks. The student will analyse spatial data to quantify and compare home range, habitat use, and activity times of feral cats at both sites, and interpret these data in terms of risks to threatened species at the sites (bridled nailtail wallabies, bilbies, and others), and ecology and control of invasive predators.
Fifteen tiny quoll pouch-young have been born to three female eastern quolls from a pioneer group of 20 animals released into Booderee National Park. In a big win for the reintroduction project, these are the first eastern quolls known to be born in the wild on the Australian mainland for more than 50 years.
Mouse-sized carnivorous marsupial the Endangered Kangaroo Island dunnart has only rarely been seen in the past 20 years. TSR Hub researcher Rosemary Hohnen is on the job working with local partners to develop better monitoring methods for the elusive species, and to evaluate the impact of feral cats on its persistence. Here she gives us a taste of the action, and despite the tiny size of the mammal there is a lot of heavy lifting…
Monitoring the nests of endangered species of cockatoos has not always been practical using traditional methods. However, new bioacoustic methods are now being applied to the monitoring of two endangered sub-species of cockatoo in southern Australia, the south-eastern red-tailed black-cockatoo and the Kangaroo Island glossy black-cockatoo. Daniella Teixeira, PhD candidate at The University of Queensland, takes up the story.
