The Lar gibbon, which is also known as the white handed gibbon was considered to make life-long pair bonds, but recent studies show how some serial monogamy with occasional partner changes and even non-monogamous groupings (10).
Generally, however, groups consist of a mated pair and their offspring. An elaborate duet sung between males and females is thought to maintain pair bonds as well as to mark and defend the pair’s territory. These gibbons breed year round, usually producing one young every two to three years.
Lar gibbons are diurnal and arboreal, inhabiting rain forests. Lar gibbons have the greatest north-south range of any of the gibbon species. The fur colorings of the Lar gibbon varies from black and dark-brown to light-brown, sandy colours. The hands and feet are white-coloured, likewise a ring of white hair surrounds the black face. Both males and females can be all colour variants, and the sexes also hardly differ in size.
