<P> Orangutans are the most arboreal of the great apes and spend most of their time in trees . Their hair is reddish - brown , instead of the brown or black hair typical of chimpanzees and gorillas . Males and females differ in size and appearance . Dominant adult males have distinctive cheek pads and produce long calls that attract females and intimidate rivals . Younger males do not have these characteristics and resemble adult females . Orangutans are the most solitary of the great apes , with social bonds occurring primarily between mothers and their dependent offspring , who stay together for the first two years . Fruit is the most important component of an orangutan 's diet ; however , the apes will also eat vegetation , bark , honey , insects and even bird eggs . They can live over 30 years in both the wild and captivity . </P>
