Not all orangutan mothers raise their infants the same way

Sumatran orangutan mothers differ from one another in how they behave with and take care of their infants and how flexibly they adjust their mothering behaviors as their infants grow. Whilst mothers differed from one another in their maternal behaviors, they remained consistent in their behaviors with their different infants. Consistent differences among Sumatran orangutan mothers suggest that individual maternal personalities may exist, potentially influencing infant development.
