Elderly Mangabey Euthanized at Think Tank

Smithsonian’s National Zoo is sad to report that Maude, the geriatric grey-cheeked mangabey, had was humanely euthanized on April 14, 2014. Maude well surpassed the typical lifespan (early 30s) of her species. She was 41 years old.

Maude was born in the Mesker Park Zoo on February 25, 1973, and came to the National Zoo in 1977. During the first year at the National Zoo, her right arm was severely injured by a gibbon in an adjacent cage, requiring her arm and hand to be amputated below the elbow. The loss of her right hand, however, never slowed her down! Maude lived with many species at the National Zoo including other mangabeys, colobus monkeys and macaques, and lived in many areas of the zoo, including the old Monkey House, the Great Ape House and most recently Think Tank.

Maude moved to Think Tank in 2011 to provide companionship for our elderly Sulawesi macaque, Spock. Due to their advanced ages, the two had outdoor and indoor spaces that catered to their specific needs. Though both animals had arthritis and other medical ailments associated with advanced age, the primate team made many modifications to their enclosures to ensure their comfort and ease in maneuvering around their exhibit. Maude enjoyed sitting out in the sun, eating grass and soaking up the rays in the outdoor enclosure with Spock.

The grey-cheeked mangabey is a species of Old World monkey found in central Africa. An arboreal species, these monkeys live in the upper canopy in social groups led by a dominant male. Listed as “least concern” by the International Union for Conservation of Nature, mangabeys, as well as many other primate taxa, are still decreasing in population due to hunting and habitat loss. Maude was the last remaining grey-cheeked mangabey in the Association of Zoos and Aquariums population.
