Geoffroy's saddle-back tamarin (Leontocebus nigrifrons) is a species of saddle-back tamarin, a type of small monkey from South America. Geoffroy's saddle-back tamarin was formerly considered to be a subspecies of the brown-mantled tamarin, L. fuscicollis.[1] [2] It lives in Loreto, Peru.[1]
Geoffroy's saddle-back tamarin has a head and body length of between 190mm and 219mm with a tail length between 305mm and 333mm long.[2] Males weigh about 354g and females weight about 369g.[2]
It lives in groups with multiple males and females.[2] It reaches sexual maturity at 18 months.[2] Both males and females emigrate from their natal group.[2] Geoffroy's saddle-back tamarin frequently associates with and forms mixed groups with moustached tamarins, Saguinus mystax.[2] The two species often sleep in the same tree and both species respond to each other's alarm calls.[2]
Its diet consists of fruits, gums, nectar, insects and other small animals.[2]
The IUCN rates it as least concern from a conservation standpoint.[2]
