Description

Red-necked Wallabies are distinguished by their black nose and paws, white stripe on the upper lip, and grizzled medium grey coat with a reddish wash across the shoulders. They can weigh 13.80 to 18.60 kg and attain a head-body length of 90 cm, although males are generally bigger than females.

, their numbers have expanded over the past 30 years because of a reduction in hunting pressure and the partial clearing of forest to result in a mosaic of pastures where wallabies can feed at night, alongside bushland where they can shelter by day. For reasons not altogether clear, it is less common in Victoria.

Behaviour

Red-necked wallabies are mainly solitary but will gather together when there’s an abundance of resources such as food, water or shelter. When they do gather in groups, they have a social hierarchy similar to other wallaby species. Red-necked wallabies are mainly crepuscular. They spend most of the daytime resting in vegetation.

A female’s estrous lasts 32 days. During courting, the female first licks the male’s neck. The male will then rub his cheek against the female’s. Then the male and female will fight briefly, standing upright like two males. After that they finally mate. A couple will stay together for one day before separating. A female bears one offspring at a time; young stay in the pouch for about 280 days, after which females and their offspring stay together for only a month. However, females may stay in the home range of their mothers for life while males leave at two years old.

Subspecies

The mainland form, Macropus rufogriseus banksianus, breeds all year round. Interestingly, captive animals maintain their breeding schedules; Tasmanian females that become pregnant out of their normal season delaying birth until summer, which can be anything up to eight months later.
