Kangaroo numbers in Australia increase and decline depending on drought. Their population from one year to the next can differ by hundreds of thousands, but as a species they are never endangered by drought.
An adult female kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This ensures the more likely survival of the young joey.
In addition, kangaroos are semi-nomadic, often moving about with the rains and according to the availability of food sources. They can travel long distances at a high speed, expending very little energy, in their efforts to reach new grazing grounds. Kangaroos are very energy-efficient, and this is linked directly to the physical action of bringing their hind legs up with each hop. Every hop literally refills the lungs. Because of the large, strong tendons in their hind legs which act as "springs", kangaroos are able to bound for longer distances than other mammals with the standard four legs can run. The springing motion requires less energy than running does, so kangaroos are better able to endure and adapt to drought conditions than most placental mammals can.

What do giant kangaroos eat?
Giant kangaroos became extinct many thousands of years ago. They were herbivores, as kangaroos are today, roaming the extensive grasslands of Australia and feeding on the grasses there. New evidence suggests that their extinction was caused by severe drought, which killed off the giant kangaroos' food supply.
Has the food source affected the population of red kangaroos?
Kangaroo populations vary widely from year to year in Australia. For example, due to drought conditions, Red kangaroo numbers in NSW dropped from 500,000 in 2002 to 110,000 in 2005. So yes - the food source does affect the population of red kangaroos, but they do repopulate in good years.

Do kangaroos migrate?
Kangaroos do not "migrate" (no native Australian marsupials migrate), but like many animal species, they are semi-nomadic, moving to where food sources are best.Kangaroos tend to remain in the area where they were born. However, in times of drought, they will move further afield in search of food.Kangaroos do not migrate, preferring to remain in the area where they were born. However, in times of drought, they will move further afield in search of food.
