The '''golden-handed tamarin''' ('''''Saguinus midas'''''), also known as the '''red-handed tamarin''' or '''Midas tamarin''', is a [[New World monkey]] belonging to the family [[Callitrichidae]].

==Distribution and habitat==
This species is native to wooded areas north of the [[Amazon River]] in [[Brazil]], [[Guyana]], [[French Guiana]], [[Suriname]], and possibly [[Venezuela]].<ref name="iucn status 19 November 2021" /> A population of tamarins south of the Amazon River that lack the contrasting feet and hands was previously believed to be a sub-population of golden-handed tamarins but is now treated as a separate species, the [[black tamarin]].

Populations of golden-handed tamarins appear to be expanding into the historical range of the [[pied tamarin]], with the golden-handed tamarin gradually displacing the pied tamarin through [[interspecific competition]].<ref name="iucn status 19 November 2021" /><ref name=Rohe>{{cite book| author = Röhe, F.| year = 2006| title = Área de contato entre as distribuições geográficas de ''Saguinus midas'' e ''Saguinus bicolor'' (Callitrichidae-Primates): a importância de interações e fatores ecológicos | publisher = Dissertação de Mestrado — INPA/UFAM | pages = 71 }}</ref>

This species prefers trees with small crowns.<ref name=AD/>

==Description==
[[File: Callitrichidae - Saguinus midas.JPG|thumb|240px|left|''Saguinus midas'']]
The golden-handed tamarin's body measures {{convert|20.5|-|28|cm|in}}; including the tail it measures {{convert|31|-|44|cm|in}}. It weighs {{convert|400|-|550|g|lb}}.

The fur of the golden-handed tamarin is dark brown or black, with contrasting golden-orange hair on its feet and hands (hence the common name). The dark face is hairless, the big ears stick out of the fur. As with all marmosets, there are claws instead of nails on the fingers and toes (with the exception of the big toe). Furthermore, the thumb is not opposable.<ref name = AD>[https://animaldiversity.org/site/accounts/information/Saguinus_midas.html Animal Diversity]</ref>

==Biology and behavior==
The life expectancy of ''Saguinus midas'' is approximately 10 years in the wild <ref name=AD/> and 16 years in captivity. These tamarins live in cooperative groups of 4 to 15 members with little competition within group even between breeding males. Adults can reach sexual maturity aged 16–20 months.<ref name=AD/> Only one female in the group will breed during breeding season with the other females suppressing the instinct. The gestation period is 140–170 days<ref name=AD/> and mothers typically give birth to two offspring. Young tamarins are cared for primarily by the father and turned over to the mother only to nurse, however the entire group helps with the care of the young. Defense is a priority in a group, and when one tamarin is threatened the others will rush to its defense. The golden-handed tamarin is territorial and can be aggressive, with sharp canines and claws instead of fingernails on all fingers and all but the large toe.

The golden-handed tamarin is an exceptional climber and spends most of its time among the vines and branches of the trees.<ref name=AD/> It is quick and agile and is a superb jumper known to jump distances of over {{convert|60|ft|m}} from a tree to the ground with no sign of injury. It is an omnivore.<ref name=AD/> Its diet consists of leaves, plant exudates, fruit, flowers, eggs, insects and other arthropods, frogs, spiders, lizards, and nectar.<ref name="iucn status 19 November 2021" /><ref name=AD/> Its natural predators include small cats, [[birds of prey]], and snakes.
