Black-mantled tamarin
The black-mantled tamarin, Leontocebus nigricollis, is a species of saddle-back tamarin from the northwestern Amazon in far western Brazil, southeastern Colombia, northeastern Peru and Ecuador.
There are 3 subspecies:
- Spix's black mantle tamarin, Leontocebus nigricollis nigricollis
- Graells's tamarin or Graells’ black-mantle tamarin, Leontocebus nigricollis graellsi
- Hernandez-Camacho’s black-mantle tamarin, Leontocebus nigricollis hernandezi
Graells's tamarin has sometimes been considered to be a separate species. The body length is 15–28 cm. The tail length is 27–42 cm.
Family groups consisting of a male, a female and 1 or 2 young live in a defined territory - the female marks branches on the boundaries of the territory with secretions of her anal glands and urine. The female gives birth to 2 young after a gestation of 140 to 150 days. It mainly eats insects, leaves, and fruit.
