Black-tufted marmosets have been observed in Pedra Selada State Park, located in the Visconde de Mauá district of Resende, Rio de Janeiro. This sighting took place on Sunday, but the information was released to the public on Tuesday. The images shared by the State Institute for the Environment (INEA) show the monkeys playfully jumping between tree branches, illustrating their active presence in the forest ecosystem.

According to INEA, these marmosets typically favor native forests but can also thrive in degraded areas, botanical gardens, and forested neighborhoods. This adaptability reflects their ability to survive in varying habitats, although they express a preference for undisturbed environments. The report emphasizes the social behavior of black-tufted marmosets, which usually live in family groups or bands, and notes their vocal and territorial nature, which contributes to their distinct presence in the environment.

The marmosets primarily feed on seeds, fruits, insects, and small vertebrates. INEA advises the public to refrain from feeding these animals, as they may display aggressive behavior when confronted. This recent sighting not only draws attention to the biodiversity in Pedra Selada State Park but also underscores the importance of preserving their natural habitat for the continued survival of such species.
