Elephants can be found in woodlands, grasslands, and forests in Africa and parts of Asia. The diet includes grass, tree foliage, bark, twigs, herbs, roots, and fruit. A herd averages 4 mph in their single file walking but can charge at 25 mph if angered or frightened. The females are known as cows, the males as bulls and the babies as calves. Elephants are gregarious, and have been found in herds of several hundred, although around 20 individuals is more common.
Elephant society is matriarchal, and is organized around a stable family unit.
Nearly all the females are related. The males are driven out of the clan at puberty, 8-20 years old. Elephant pregnancy averages 22 months with the birth of a single calf weighing around 200 pounds. Twin births are rare. The herd will wait for the youngster to be able to travel with the herd before they move on, usually 2-3 days.
