Wied's marmoset is highly social, spending much of its time grooming.

The coloring of Wied's marmoset is mostly black, with white markings on cheeks and forehead.

Unlike other marmosets, Wied's marmoset lives in groups consisting of 4 or 5 females and 2 or 3 males (plus children).

Wied's marmoset (Callithrix kuhlii), also known as Wied's black-tufted-ear marmoset, is a New World monkey that lives in tropical and subtropical forests of southeastern Brazil.

Since these are harvested from the middle and lower part of the forest, Wied's marmoset often travels and forages in the company of the golden-headed lion tamarin, which forages in the canopy.

Within the aviary are some enclosed animal exhibits that are home to animals such as scarlet macaws, Wied's marmosets, Golden-headed lion tamarins, Linnaeus's two-toed sloth, Chilean flamingos, and black swans.

Wied's marmoset is eaten by birds of prey (the Harpy Eagle, the Gray Hawk, the Roadside Hawk and the White-tailed Hawk), felines (the Jaguar, Jaguarundi and Ocelot) and snakes.
