Is the Gilbert’s potoroo Australia’s most critically endangered mammal?
A diet study of Australia’s most critically endangered mammal, Gilbert’s Potoroo, Potorous gilbertii ( Marsupialia: Potoroidae ). (Unpublished Honours thesis). Edith Cowan University, Perth, Australia.
Can Gilbert’s potoroos be bred in captivity?
Initially, considerable effort went into attempts to breed Gilbert’s Potoroos in captivity. However, this proved unreliable, and efforts turned to assisted reproduction techniques including artificial insemination and cross-fostering using Long-nosed Potoroos ( Potorous tridactylus ). Unfortunately, neither of these methods were successful.
Do potoroos nest in pairs?
Like other potoroos, these animals are mainly solitary, with little overlap in home range between individuals of the same sex, although a male and a female may be found nesting together under the dense sedges in their heathland habitat, sometimes with a young-at-heel.

A female potoroo rears one young at a time, but up to three a year, so she could produce well over 20 progeny in her lifetime. Discovered near Albany in 1840 by John Gilbert, the renowned collector for British taxonomist John Gould, Gilbert’s Potoroos were never widespread.
