Meet our soulful siamangs!

Adelaide Zoo is home to six siamangs living in two family groups.

The group that lives near the Nocturnal House consists of a male, female and their son. Dominant male, Irian was born on 4 May 2001 at Auckland Zoo, arriving at Adelaide Zoo in 2006, while female Suli was born on 15 May 2000 at Edinburgh Zoo, arriving at Adelaide Zoo in 2006. Their son, Zain, was born on 6 January 2009. He’s the equivalent of a teenager and as expected is always testing the boundaries and if full of energy and can be quite cheeky when interacting with zoo keepers often trying to play with sunglasses or keys. The families’ favourite treat is grapes!

The simang group that lives on the island of our South East Asia habitat consists of another family group. Dominant male, Niran was born on 24 June 1989. He can be recognised by his distinct grey hair and is very much the peacekeeper of the family group. Our female Mang, who was born on 21 October 1988 at San Francisco Zoo, arriving at Adelaide Zoo in 1997, is the most dominant in the group and calls all the shots. Their son, Jars, was born on 24 June 2001 and can often be seen sitting near the running water of the pond surrounding his island home. The groups’ favourite treats are grapes and environmental enrichment, especially fig leaves covered in seeds.

The Siamang is species of gibbon native to the forests of Malaysia, Thailand and Sumatra. They are the largest of the lesser apes, usually at least twice the size of other gibbons.

Siamangs live in small monogamous family groups of a dominant male, female and their offspring, ranging from infants and sometimes sub-adults. Males tend to offer more parental care than other gibbon species, helping to care for the infant the majority of the time around the age of eight months old.

The Siamang is well known for its loud, throaty call. These calls are usually heard in the early morning and throughout the day, easing off after mid-day. These loud calls help mark their territories and strengthen bonds between the family group. The call is actually a duet between the male and female, with each having a very specific part to sing.

Grooming is one of the most important social activities among family members and usually takes place between the adults in the morning and the adults groom the juveniles later in the day.

The greatest threat to the Siamang is habitat loss caused primarily by logging, forest conversion for agriculture and the clearing of land for palm oil plantations and poaching and hunting for the illegal pet trade. To obtain Simangs for the illegal pet trade, hunters must first kill the mother, since Siamang females are highly protective of their infants, in order to obtain the infant.
