Parents Tema and Danso and the staff at Dublin Zoo are celebrating the birth of a female white-crowned mangabey.
The baby was born on November 11 and weighs 400g.
Yet-to-be-named, she is the third addition to Tema and Danso's family.
Helen Clarke-Bennet, Team Leader at the African Plains, said: "We are very proud of the new mangabey arrival at Dublin Zoo. This is Tema's third baby and she is a fantastic mum. She takes everything in her stride and Danso is a very protective dad.
"The new arrival will stay close to her mother for about a year but will eventually become more independent."
Dublin Zoo says: "White-crowned mangabeys are listed as endangered in the wild by the International Union for Conservation of Nature (IUCN) red list because their population is decreasing rapidly.
"Dublin Zoo is one of 12 zoos in Europe participating in a breeding programme and has a very successful breeding record, with 18 white-crowned mangabeys born at the Zoo in the last 10 years."
