Keepers at Twycross Zoo in Leicestershire are celebrating after the birth of an endangered orang utan.
The ape was born on November 28th and is the third to be born at the attraction and conservation centre this year.
Keepers at the zoo have described the birth as a vital addition to the European Breeding Programme to ensure the survival of the endangered ape.
Experts believe the species are likely to be extinct in the wild within around 20 years, and say breeding in captivity like this is essential.
Zoo keepers are keeping a close eye on a seven-week-old baby De Brazza monkey over the coming weeks as they try to choose a name.
The youngster was born in October at Twycross Zoo and has already proved a hit with visitors due to his adventurous antics.
Senior primate keeper Sarah Dee said keepers like to get to know their monkeys' personalities before they decide on a name.
An adorable baby De Brazza's monkey has been born at Twycross Zoo.
Zoo keepers welcomed the bouncing baby boy seven weeks ago, and the youngster - who has yet to be named - has now been put on display to visitors, where his adventurous antics are making him a popular attraction.
Part of the guenon family, the De Brazza newborn has the breed's signature orange cresent-shaped patch on his forehead and white muzzle, which extends into a beard.
The De Brazza is approaching the benchmark to be classed as a threatened species, as they suffer from the loss of their natural habitat due to deforestation and hunting.
Senior primate keeper Sarah Dee said he has bonded well with his mother Ludo and dad Tom, and loves playing with his older sister Afia.
From day one he was very alert and within a week or so he was leaving mum to explore his new surroundings.
His adventurous nature has given our visitors a great opportunity to see the youngster at such an early age, and he’s definitely winning them over with his looks.
Afia loves playing with her new brother and we often see her carrying him around and the two playing chase with one another.
Ludo is an experienced and confident mum, so although she lets her newborn play she’s never far behind to keep him out of mischief.
Three South American bush dogs have been born at Twycross Zoo, the first litter of bush dog pups to be born at the Zoo in almost a decade.
The pups arrived safely on 21st August 2013. The pups have so far remained off show in their nest, but are now beginning to venture into their outdoor viewing area and explore their new surroundings.
Bush dogs are members of the dog family and produce a strong scent that resembles vinegar. This has led to them being nicknamed the 'vinegar dog'. Bush dogs are well adapted for a semi-aquatic lifestyle and have webbed feet to aid swimming.

Two snow leopards will go on full view to the public at Twycross Zoo for the first time.
The brothers were born on 1 May and have been settling down in an off-show area with their mother, Irma.
Cameras placed in an off-show den allowed zoo staff and vets to watch the births live, and keep a close eye on the cubs without disturbing the new mother.

Twycross Zoo's group of chimpanzees who made their way into an area of the zoo they should not have been in were offered ice cream and fizzy drinks as a bargaining tool.
Zookeepers at the Leicestershire zoo had to coax the animals out of the secure area this morning by offering them the sweet treats, which left them "a little excited."
The zoo was closed for less than two hours due to "safety procedures", but "no people or chimps were harmed during the incident".
