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.

It is Threatened Species Day on 7 September. If you are a threatened species in Australia, chances are you are on Indigenous-managed land, as it is the last stronghold for many species which have been lost from the wider landscape .
New research has found that habitat loss is a major concern for hundreds of Australian bird species, and south-eastern Australia has been the worst affected. The Threatened Species Recovery Hub study found that half of all native bird species have each lost almost two-thirds of their natural habitat across Victoria, parts of South Australia and New South Wales.
Kanyirninpa Jukurrpa (KJ) Rangers in the Martu Determination have collaborated with Threatened Species Recovery Hub scientists to design a monitoring program for mankarr (the greater bilby). Martu people identified priorities for the bilby monitoring program, then worked with Dr Anja Skroblin from The University of Melbourne to co-develop a monitoring method which brings together Martu knowledge and practice with Western conservation science.

A new project is aiming to increase city kids’ connections with nature, threatened species conservation and Indigenous culture. Dr Georgia Garrard from RMIT University talks about this project, which will see Wurundjeri Woi-wurrung Traditional Owners working with kids at Carlton North Primary School in Melbourne and Gunditjmara Traditional Owners working with kids at Heywood Consolidated School in western Victoria.
