The Great Grey Kangaroo (Macropus giganteus) is a marsupial found in the eastern third of Australia, with a population of several million. It is also known as the Forester kangaroo.

Although a Great Grey Kangaroo male typically weighs around 146 lb and stands almost 6 ft 7 in. tall, the scientific name, Macropus giganteus (gigantic large-foot), is misleading: the Red Kangaroo of the semi-arid inland is larger, weighing up to 200 lb.

The Great Grey Kangaroo is the second largest and heaviest living marsupial and native land mammal in Australia.

An adult male will commonly weigh around 110 to 146 lb. whereas females weigh around 37 to 88 lb. They have a powerful tail that is over 3 ft 3 in. long in adult males.

Great Grey Kangaroo or Eastern Grey Kangaroos are gregarious and form open-membership groups. The groups contain an average of three individuals.

Smaller groups join to graze in preferred foraging areas, and to rest in large groups around the middle of the day. They exist in a dominance hierarchy and the dominant individuals gain access to better sources of food and areas of shade. However, kangaroos are not territorial.

Great Grey Kangaroos adjust their behavior in relation to the risk of predation with reproductive females, individuals on the periphery of the group and individuals in groups far from cover being the most vigilant.

Vigilance in individual kangaroos does not seem to significantly decrease when the size of the group increases.

There is a tendency for the proportion of individuals on the periphery of the group to decline as group size increases. The open membership of the group allows more Kangaroos to join and thus provide more buffers against predators.
