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.

Karajarri Rangers are leading a Threatened Species Recovery Hub research project to investigate how different fire management approaches affect biodiversity. The first field trip took place in April this year, when a team of 16 rangers, support staff and scientists journeyed to the Edgar Ranges for eight days of wildlife monitoring. Hub researcher Sarah Legge worked with the rangers to compile this report from the field.
Cissy Gore-Birch is a member of the Threatened Species Recovery Hub’s steering committee and the Chair of its Indigenous Reference Group. The Indigenous Reference Group was established to assist hub leaders and project teams to strengthen the engagement and participation of Indigenous people in the hub’s activities and research projects. Cissy recently attended the Species of the Desert Festival on the Paruku Indigenous Protected Area, where she spoke about both threatened and culturally important species, and increasing the voice of Indigenous people in environmental policies and research.
Dr Sally Box, the Australian Government’s Threatened Species Commissioner, talks about the importance of working with Indigenous groups to conserve Australia’s threatened species.
Researchers from the Threatened Species Recovery Hub are calling on citizen scientists to help them learn more about Australia’s possums and gliders by recording sightings in a new, free app. Dr Rochelle Steven from the University of Queensland is passionate about Australia’s possums and gliders and believes people in the community can do a lot to help support conservation, especially in urban areas.
There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
