This native timber brooch features the Macrotis lagotis Bilby, found in semi-arid areas of Western Australia. The Bilby is also famous for being one of fastest breeding mammals on Earth with a 12 to 14 day pregnancy. There are many threats contributing to the dramatic decline of Bilby populations, the most important of these are habitat loss and change and competition with introduced animals such as foxes and feral cats. Bilbies can be seen at Perth Zoo Noctural house.
