A battle for control of a small group of Werribee icons has led to a change of leadership.
At age 14, Yakini, the western lowland gorilla, has taken over from his father, Motaba, as the dominant silverback at Werribee Open Range Zoo.
Yakini was hand-raised by keepers at Melbourne Zoo for almost a year following a difficult caesarean birth.
Now weighing more than 170 kilograms, he is much heavier than his father and brother, Ganyeka.
Keeper Kat Thompson said the change in the group’s social structure had been relatively smooth, with Motaba gradually conceding his spot to Yakini.
“As Yakini matured, it was natural that he would challenge his father for the position as leader of the group,” Ms Thompson said.
“The challenge for leadership took place over several months and was very subtle – a battle of wills rather than a battle of brawn.”
She said there had been subtle changes in body language between the two, with Yakini asserting his right to eat first and take first pick of the outdoor shelters.
“Having such a large exhibit with undulated areas meant that during tense periods Yakini, Motaba and Ganyeka were able to retreat to their own space while peace was restored,” she said.
“Yakini’s relationship with keepers has also changed. He still has a very sweet nature but as leader he has become a lot more serious and a bit bossy.”
