This is also known as the Parkland or Park Savanna. Big game lands of the world are here, consisting of large animals particularly, ungulates and carnivores. As they move about, they break up into smaller bands and reform. Their groups consist of adult males, females and their young. The male chimpanzee is the most dominant.
Female chimpanzees come into estrus once a month.
They have a 35-day menstrual cycle and can breed at anytime of the year. The gestation period is more than seven months long, and a single offspring is produced. The baby offspring is totally dependent upon its mother up until the age of four or five. The baby chimpanzee will grasp to its mothers' chest and hold on while traveling. As it matures it will ride on its mothers' back.
