Habitat
This species inhabits the Atlantic Forest regions of eastern Brazil, including tropical and subtropical forests, secondary growth, and urban edges. They prefer areas with dense vegetation for cover and access to tree exudates. Their range extends from Bahia to Minas Gerais, often in lowland and montane forests up to 1,000 meters.
Diet
Black-tufted marmosets primarily eat tree gums, fruits, and insects, which they forage from trees and under bark. They also consume flowers, nectar, and small vertebrates like lizards. Feeding occurs mainly in the early morning and late afternoon when they are most active.
Behavior
They live in small family groups of 3-15 individuals, typically led by a dominant breeding pair, and communicate through vocalizations and scent marking. Black-tufted marmosets are diurnal and arboreal, spending most of their time in trees, and they defend territories aggressively against intruders. They exhibit cooperative behaviors, such as shared parenting among group members.
Conservation Status
The IUCN classifies the black-tufted marmoset as Least Concern, though populations are declining due to habitat loss from deforestation and urbanization. Major threats include fragmentation of forests and the pet trade.
