Critically-endangered Sulawesi crested macaque born at ZSL London Zoo

Standing eight inches tall and weighing in at just 800grams, ZSL London Zoo's tiny new arrival is already making a big impression. 

Sulawesi crested macaque baby

The three-week-old Sulawesi crested macaque was born to 17-year-old Winoo after a 174-day-long gestation period.  

Expected to triple its weight before autumn this year, the critically-endangered infant, who is yet to be named, is being nursed by mum Winoo and will be for at least another six months before gradually moving on to a diet of fruit, leaves and insects. 

Fathered by dominant male Gaston, the infant is the latest addition to the eight-strong troop of Sulawesi crested macaques at the Zoo. 

Zookeepers are yet to determine the gender of the baby who stands out from the adults, with its pale features and blue eyes. The new-born's eyes will darken with age, and the macaque's iconic crest of hair will soon appear. 

Zookeeper Paul Kybett said: "The team at ZSL London Zoo are delighted by the arrival of a new Sulawesi crested macaque, and pleased to confirm that mum and baby are both doing well.

"These are sociable monkeys that form close bonds with each other and the group are all showing a keen interest in the new arrival. 

"The other youngsters in the group will be delighted to have a new playmate, but for now experienced-mum Winoo will be keeping a close eye on her baby."

An important addition to the European breeding programme for endangered species, Sulawesi crested macaques are under constant threat in the wild from habitat loss and poaching.
