About Notamacropus parryi Bennett, 1835
This species, commonly known as the whiptail wallaby, can be distinguished by its paler overall colouring and a white stripe running under its face. Chocolate-brown fur covers the muzzle portion of the face. The chest is patterned black and white, and the rest of the body is covered in fur ranging from grey to brown. Male whiptail wallabies weigh between 14 and 26 kg (31 to 57 lb), and stand 70 to 93 cm (28 to 37 in) tall. Females weigh between 7 and 15 kg (15 to 33 lb), and stand 65 to 75 cm (26 to 30 in) tall. Only the most dominant males mate with females. A male wanders through groups of females, sniffing their cloacae and tasting their urine to assess reproductive status. When a male locates a female approaching oestrus, he remains with her, but may be replaced by a more dominant male before she enters oestrus. The oestrus cycle of the whiptail wallaby lasts 42 days. Joeys remain in their mother's pouch for the first nine months of life. After leaving the pouch, they will still stay with their mother for up to 18 additional months. Whiptail wallaby joeys follow their mothers continuously and do not hide in vegetation. Subadult male whiptail wallabies sometimes leave their natal groups.
