The baby was born on 3 February
A second Sumatran orang-utan baby has been born at Chester Zoo in less than 12 months.
Subis, 22, gave birth to the baby on 3 February, bringing the number of the critically-endangered orang-utan species at the Cheshire zoo to eight.
She has the same father as Sumatran orang-utan Indah, who was born at the zoo last February.
Visitors to the zoo's Realm of the Red Ape enclosure are now being asked to name the new arrival.
They will be asked to cast their votes for one of six names - Tuti, Adinda, Sari, Kirana, Bethari and Bonita - from Saturday until 1 March.
Kevin Buley, Head of Zoo Programmes, said: "Orang-utans give birth every six to eight years, so you can imagine our delight at seeing two new arrivals in quick succession.
"Subis has proved to be a good mother previously and we're happy for her to carry on her good work. She is taking great care of her new charge and already proudly showing it off to our visitors.
"We're a bit stumped with the names though, so we are asking anyone who visits the zoo during February half-term to have a look at the baby in Realm of the Red Ape and then vote for the name they think would suit."
Baby orang-utans are naturally small - tipping the scales at between 1.5 and 2kgs.
