Orangutans take bonding with their newborns very seriously.
Female Orangutans live up to 45 years, yet in all their life time, they give birth to not more than 3 infants. After reaching maturity at the age of 15 or 16, female Orangutans give birth once every 7 or 8 years. This makes them perhaps, some of the slowest breeding mammals on our planet. They nurse their young until they reach the age of 7 or 8 before they have the next infant.
The bond between mother and newborn Orangutan is remarkably strong. In the first year of its life, an infant Orangutan is almost permanently glued to its mother’s body. After that, it will never stray far away from her until the next infant is born. Adolescent females may linger and observe how their mothers care for newborn babies.Young males however, are pushed away by their mothers shortly after a new sibling is born. They will then wander through the forest alone, covering an area of approximately 15 square kilometers or more. They tend to avoid other males and meet with females only to mate.
Females always stay in a much smaller tract of forest through out their life time. Occasionally, they feed with other females in the same tree, but even then, there is little or no socializing. The solitary life of Orangutans makes them unique among apes.
