The Red Kangaroo (Osphranter rufus) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial.
O. rufus or Red Kangaroo’s are found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the eastern and southeastern coasts, and the rainforests along the northern coast.
The Red Kangaroo’s legs work much like a rubber band, with the Achilles tendon stretching as the animal comes down, then releasing its energy to propel the animal up and forward, enabling the characteristic bouncing locomotion.
They can reach speeds of around 37 mph. The males can cover 26 to 30 feet in one leap while reaching heights of 5 ft 11 in. to 9 ft 10 in., though the average is 3 ft 11 in. to 6 ft 3 in.
O. rufus or Red Kangaroos live in groups of 2 to 4 members. The most common groups are females and their young. Larger groups can be found in densely populated areas and females are usually with a male.
Membership of these groups is very flexible, and males (boomers) are not territorial, fighting only over females (flyers) that come into heat.
O. rufus or Red Kangaroo males develop proportionately much larger shoulders and arms than females. Most agonistic interactions occur between young males, which engage in ritualised fighting known as boxing.
They usually stand up on their hind limbs and attempt to push their opponent off balance by jabbing him or locking forearms. If the fight escalates, they will begin to kick each other. Using their tail to support their weight, they deliver kicks with their powerful hind legs.
Compared to other kangaroo species, fights between Red Kangaroo males tend to involve more wrestling.
Fights establish dominance relationships among males, and determine who gets access to estrous females. Dominant males make agonistic behaviors and more sexual behaviors until they are overthrown. Displaced males live alone and avoid close contact with others.
