The Black-Headed Marmoset (Mico Nigriceps) is a New World Monkey in the Callitrichidae family of monkeys and can be found in certain regions of the Amazon rainforest in Brazil. While once argued that the Black-Headed Marmoset was actually a slight variation of Emilia’s Marmoset, there are a few differences that make this monkey a unique species of its own. Most notably, the Black-Headed Marmoset has a darker overall color, a more orange hued color on its rear legs, and a larger head and arm length.
The Black-Headed Marmoset is typically identified in a specific region of Brazil ranging from Rio dos Marmelos in the north and east, the Rio Madeira in the west, and the Rio Jiparaná in the south. These locations all reside in the state of Rondônia, Brazil. The Black-Headed Marmoset typically dwells in the rainforest’s canopy where it has the most abundant source of nutrients.
Like many other members of the family, Black-Headed Marmosets usually eat fruits, flowers, nectar, and other plant exudates such as gum, sap, and latex. However, when the need arises, they are able to diversify their diet and eat other sources of nutrition such as frogs, snails, lizards, spiders, and other small insects or animal prey. While they typically stick to eating plant exudates, they occasionally need to get creative in times of drought or when travelling through less food-dense areas of the rainforest.
