Red kangaroo

Osphranter rufus

A kangaroo’s bounce stores energy before it releases it.

The red kangaroo lives across dry, open landscapes of western and central Australia. Its life is not simply a contest of spectacular jumps: finding green food, resting in shade and deciding when to move are equally important. Its muscular hindlimbs and strong tail fit within that wider daily routine.[1]

The spring inside a hop

As the kangaroo lands, its Achilles tendon stretches; energy stored in that stretch is released into the next upward and forward motion. The muscles and tendons work together rather than producing every movement as a fresh, isolated push. Its large hindlimbs make hopping conspicuous, while the strong tail also supports the animal when it stands upright.[1]

Finding green in a dry landscape

Red kangaroos select green vegetation even when much of the landscape looks brown. Grasses and forbs are preferred, with some shrubs used when favoured foods become scarce. Rainfall can change where the useful plants are, so movement follows the distribution of food rather than a simple rule that every kangaroo continually wanders across the desert.[1]

Open country still needs shade

Grassland, scrub and desert habitat can all be used, but shelter from heat matters within these open spaces. Much activity is at dusk, night and dawn, with daytime rest in shade. Many individuals remain within relatively defined home ranges; environmental change can prompt longer journeys. Local shelter and regional food supply therefore shape movement at different scales.[1]

A COMMON MIX-UP

Must every red kangaroo have red fur?

No. Males commonly have reddish-brown coats, while females are often blue-grey; colour also varies with region.[1]

TRY A LITTLE REASONING

After patchy rain, why might kangaroos concentrate in one area rather than spread evenly?

Reveal the explanation

Rain changes where fresh green food is available. Animals can follow that uneven resource, so identical areas of ground need not offer identical feeding opportunities.[1]
