A GENDER reveal party was held for Dudley Zoo’s newest addition as keepers placed two enrichment boxes packed with coloured plastic balls into the gelada’s indoor den.

It didn’t take long for dad Ebano and adult female, Tana, to tip out blue balls and reveal the youngster is a boy - his fourth son.

The newborn, who was born to mum, Addis, on December 21 has been named Dendi by keepers, after Mount Dendi, the second highest volcano in Ethiopia, the native home of the species.

He joins brothers Billie, Gimbi and Ambo – who spent hours afterwards playing with the ball pit balls – in their award-winning half-acre natural hillside enclosure on the lower zoo site.

The geladas form part of an European Endangered Species Programme and the zoo has been successfully breeding them since 2014.

Gestation is usually around six months and mothers will carry the baby on their stomach for the first few weeks, before transferring it to their back.

The youngster will begin to gain more independence around five-months-old.
