Eastern Grey Kangaroo Mating Habits

by Wildlife Adm November 06, 2023

Eastern grey kangaroos are polygynous animals. Adult males take part in ritualized fights with rivals, and the dominant male being the most likely the only one to mate with the available females. Breeding continues throughout the year, peaking in summer. The young is born following a gestation period of 36 days. At about 9 months old, the joey leaves its mother's pouch for short periods, exploring the world with very brief little hops around the mother. Joey leaves its mother's pouch at 11 months old, though it is still suckling. When the joey is 18 months old it is fully weaned and leaves the pouch permanently. Females are reproductively mature at about 20 to 22 months, and males at 43 months.
