Baby gorilla born at Durrell in Jersey is a boy

Keepers discovered the baby gorilla born last month was a boy

The Durrell Wildlife Conservation Trust has discovered the first baby gorilla to be born there in nearly a decade is a boy.

Hlala Kahilli gave birth to Indigo on 27 September but a spokesman said the sex was not known until last week.

Keepers named the gorilla before discovering its sex.

Indigo is the first offspring of Badongo a male silverback who arrived at the zoo in July replacing Ya Kwanza, who had not bred for eight years.

Ya Kwanza moved to a new home with a bachelor group of gorillas in France at La Vallée des Singes, near Poitiers.

Gorilla keeper at Durrell Jon Stark said: "We discovered that Indigo was in fact a little boy when Kahilli was giving him a thorough top to toe clean.

"We had suspected as much from a few blurry photographs taken by staff and visitors alike but now we can confirm this for sure.

"We are delighted that Badongo has a son who we hope one day will become as magnificent and gentle as his father."
