Wied's marmoset
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 eastern Brazil. Unlike other marmosets, Wied's marmoset lives in groups consisting of 4 or 5 females and 2 or 3 males (plus children). They are matriarchal, and only the dominant female is allowed to mate. Like other marmosets, the offspring are always born in pairs. Diet This monkey supplements its diet of sap with fruit, nectar, flowers and seeds, as well as spiders and insects. 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. Natural Predators 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. Behavior Wied's marmoset is highly social, spending much of its time grooming. It has individually distinctive calls, and it communicates through gestures and olfactory markings as well. Appearance The coloring of Wied's marmoset is mostly black, with white markings on cheeks and forehead. It has rings on its tail
