MILWAUKEE — The Milwaukee Zoo announced Tuesday it has welcomed a pair of DeBrazza's monkeys to the Primates of the World Building: Holly, a female, and Hugo, a male. 

DeBrazza's monkeys, which is a new species to the zoo, aren't as common compared to other species. According to the International Union for the Conservation of Nature, they are labeled as "stable" in the wild, however, they face dangers of deforestation and the pet trade.

Holly, 5, and Hugo, 4, arrived through accredited zoos as part of the Association of Zoos and Aquariums Species Survival Plan, which helps selected species survive in zoos and aquariums. Most of the species are either endangered or threatened in the wild.

Holly and Hugo are getting acclimated to their habitat. DeBrazza's monkeys are colorful, known for their white facial hair resembling a beard. They also have white bellies, a speckled gray coat with black touches, and they are known to have an "elegant" appearance.

“We were looking to add a new species to the Primates of the World building, and DeBrazza’s monkeys were a great fit," Curator of Apes and Primates Trish Khanin said in a press release.

In the wild, DeBrazza's monkeys spend most of the time in trees and shrubs in between the forest canopy and the ground, and their habitat at the zoo has been updated to reflect their natural homes. These kind of monkeys can also swim and usually live near water sources.
