One individual (left) has 4 limbs in contact with the ground, another (middle) has only 2 limbs and the tail in contact, and another (right) is standing erect on its 2 hind legs and supported by the tail. Kangaroos can stand erect on their hind legs, supported by their tail as the third leg of a tripod (they can even balance on their tail alone).
Kangaroos have a unique three-stage walk where they plant their front legs and tail first, then push off their tail, followed lastly by the back legs. The propulsive force of the tail is equal to that of both the front and hind legs combined and performs as much work as what a human leg walking can at the same speed.
Humans, gibbons and large birds walk by raising one foot at a time. On the other hand, most macropods, smaller birds, lemurs and bipedal rodents move by hopping on both legs simultaneously. Tree kangaroos are able to walk or hop, most commonly alternating feet when moving arboreally and hopping on both feet simultaneously when on the ground.

Males do a lot of intraspecific competition for mates which includes male-male fights to determine dominance between the two males. When a dominant male finds a female in estrus, he will court the female and eventually they copulate. [23]
How many legs does a kangaroo have? Four, right? Well, according to new research, the right answer is actually five. Yes, five. A study published in Biology Letters online Thursday says, when ...
Groups of kangaroos, also known as mobs, are led by one alpha male who may have had a serious battle to earn his position. Mobs can be made of just a few individuals, or over 100.
