Habitat
This subspecies inhabits tropical rainforests in northwestern Colombia, particularly in the Magdalena River valley and surrounding lowlands. It prefers dense, primary and secondary forests with ample understory vegetation for foraging and shelter, often near rivers or streams. They are adaptable to fragmented habitats but thrive in areas with tall trees for movement.
Diet
Hernandez-Camacho's black-mantled tamarin primarily eats fruits, insects, and tree sap, with a preference for ripe berries and gum from certain trees. They forage in groups during the early morning and late afternoon, using their sharp claws to extract food from bark and foliage. They occasionally consume small vertebrates like frogs or lizards to supplement their diet.
Behavior
These tamarins live in small social groups of 4-15 individuals, typically led by a dominant female, and engage in cooperative care of offspring. They are diurnal and highly arboreal, spending most of their time leaping between trees and marking territories with scent glands. They communicate through a variety of vocalizations, such as whistles and chirps, to coordinate group activities and warn of threats.
Conservation Status
The IUCN status is Vulnerable, with population trends showing a decline due to habitat loss from deforestation and agriculture. Major threats include fragmentation of rainforest habitats and capture for the pet trade.
