The black-mantled tamarin^[1] is a saddleback tamarin native to northwestern Amazonia in far western Brazil, eastern Ecuador, southeastern Colombia, and northeastern Peru.

• These South American tamarins have a black coat extending from their heads to the middle of their backs, fading to a reddish hue.
• The feet, hands, and tail are all black. They have hairless ears and whitish fur around the snout.
• Black-mantled tamarin that lives west of the Iquitos River differs from those that live east.
• West of Iquitos, they have blackish-gray olive forequarters, while the lower half is blackish-olive yellow.
• The tail length is between 356 and 361 mm, almost twice the length of the body. And the females weigh around 480g, which is 10g more than the males.

• Leontocebus nigricollis live in small multi-male and multi-female social groups of 4 to 12 and occupy 30 to 50 hectares.
• Mixed-species associations have been reported between black-mantled tamarins and saddleback tamarins. Mixed-species groups are thought to be formed to help protect themselves against predators.
• Compared to other primate species, tamarins start their daily activities late in the morning, a few minutes to an hour after sunrise.
• They are charismatic members of pristine rainforests, making them possibly valuable for ecotourism.
• Forest destruction is the main reason Black-mantled tamarins are marked as threatened by IUCN.
