A new arrival to the white-crowned mangabey troop is among the stars of The Zoo on RTÉ One tonight, Thursday May 8, at 7:00pm.

In Thursday's episode, we meet the third baby born to mangabeys Tema and Danso, who weighs a healthy 400g.

Also on Thursday's show, the team must find a method to feed a pair of Abyssinian ground hornbill chicks, while an Amur tiger shows signs of a leg injury and must have an x-ray and ultrasound.
