Eastern grey kangaroo

They have a strong preference for tender grass but rely on a wide variety of plants and foliage. They prefer young shoots, higher in protein than dry grass, which is difficult for them to digest. As for the females, they produce milk which varies in composition depending on the age of their offspring.

Only females have a ventral pouch. Called a marsupium, it receives the fetus, which is then about 30 days old, and protects its development until the age of 9 months. Although females have only one joey per litter, it's possible to observe more than one young in the pouch, at different stages of growth.

A group usually consists of a single dominant male, two or three females and their joeys. To test their dominance, the males will engage in impressively choreographed fights. If they persist, the fighting may lead to solid hind leg blows, well supported by their tail.

Numbered in the millions in Australia, they compete for resources with farm sheep, infuriating farmers. Collisions with kangaroos account for 90% of all road traffic accidents involving wildlife. Kangaroos are among the most popular animals in children's stories, including "Winnie-the-Pooh".
