The parma wallaby is a solitary, nocturnal, cryptic creature which spends the daytime sheltering under cover (11) Shortly after waking at dusk, the parma wallaby commences feeding, typically congregating in small groups of two to three individuals to forage. Its diet consists of herbs and grasses (11). The majority of social interactions occur at dawn, when there is a peak in activity, although social interactions account for around just two percent of a parma wallaby’s daily activity (11).
In captivity, female parma wallabies reach sexual maturity between 11 and 16 months of age, while males mature later at 22 months (12). Pairs bond through a courtship ritual involving the female rubbing her head against the male’s chest, the male pawing and sniffing the female’s rump, and pronounced ‘clucking’ vocalisations by the male and ‘hissing’ by the female (11). A female parma wallaby releases only a single egg at a time but can produce multiple offspring within a breeding season, as the female can become fertile again only days after giving birth (12).
Offspring, known as joeys, are born between February and June (5), after a gestation period of 30 to 32 days (12). Like all marsupials (5), the undeveloped young immediately crawls up the mother’s stomach to the pouch, where the remaining development takes place (12). Infants leave the pouch for short intervals by 175 days of age (6).
