Brown-mantled tamarin

The brown-mantled tamarin (Leontocebus fuscicollis), also called Spix's saddle-back tamarin, is a small New World monkey of the family Callitrichidae found in Bolivia, Brazil and Peru. It lives in primary and secondary lowland tropical forest in northern Amazonia and tends to stay lower in the canopy than other primates. Adults are roughly 21 to 23 centimetres long, weigh between about 350 and 450 grams, and have orange-yellow fur with black patches and a long tail that is not prehensile. The species is diurnal and arboreal, omnivorous, and lives in groups of about four to fifteen animals that communicate by voice and scent. Four subspecies are recognised, and several animals once treated as its subspecies, including Geoffroy's and Weddell's saddle-back tamarins, are now regarded as separate species. The IUCN lists it as Least Concern, although the population is decreasing under pressure from poaching, habitat loss and the illegal pet trade.
