Abstract: Helping behaviour, defined as the care of offspring by individuals
other than their parents, appears to be particularly common in monogamous mammals.
Although all gibbon species typically live in monogamous family groups, there are
extremely few observations of helping behaviour (usually in the form of carrying
younger siblings). This paper reports on helping behaviour observed in a captive
family group of pileated gibbons (Hylobates pileatus) at the Zürich Zoo.
These observations were made during a study on the behavioural development of an
infant pileated gibbon reared in its natal group during its first year of life.
