Every gorilla over 3 years old makes a nest to sleep in each night, using bent branches or grass.

Established in 1972, AERP is the longest-running study of elephants in the world. Cynthia Moss, director and founder of the project, meticulously records the births, deaths, family relationships and other dramatic events in the lives of over 900 elephants in Amboseli National Park in Kenya. The project produces invaluable information on elephant social behavior, reproductive patterns, intelligence, family life and communications, which is shared with other researchers and institutions around the world. Since the elephants of Amboseli have been mostly spared from disturbances that threaten elephants, such as poaching for ivory, they serve as a critical example of a relatively undisturbed population. Helping People and Elephants Get Along in the Greater Amboseli Ecosystem Imagine raising your family exclusively on the vegetables you grow and the cows and goats you herd.
