At birth, the young, called joeys, are less than an inch long, naked and blind, and weigh about an ounce. Immediately after birth the joey finds its way to the pouch where it lives for the next four to five months.
The kangaroo’s normal rate of travel is 5-10 mph. The broad, heavy tail is used as a prop when sitting or moving slowly to give impetus to hops, and it gives balance and control to the body during flight. Kangaroos enjoy “boxing” matches with each other and will balance on the tail while boxing and kicking. If cornered or frightened, the kangaroo will balance on the tail and kick with both feet in an effort to kill or injure the attacker.
