Saimiri
Squirrel monkeys are New World monkeys of the genus ''Saimiri''. ''Saimiri'' is the only genus in the subfamily Saimirinae. The name of the genus is of Tupi origin (''sai-mirím'' or ''çai-mbirín'', with ''sai'' meaning 'monkey' and ''mirím'' meaning 'small') and was also used as an English name by early researchers. Squirrel monkeys live in the tropical forests of Central and South America in the canopy layer. Most species have parapatric or allopatric ranges in the Amazon, while ''S. oerstedii'' is found disjunctly in Costa Rica and Panama. There are two main groups of squirrel monkeys recognized. They are differentiated based on the shape of the white coloration above the eyes. In total there are 5 recognized species. Squirrel monkeys have short and close fur colored black at the shoulders, yellow or orange fur along the back and extremities, and white on the face. Squirrel monkeys have determined breeding seasons which involve large fluctuations in hormones and there is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saimiri Boliviensis
The black-capped squirrel monkey (''Saimiri boliviensis'') is a species of New-World monkey native to the upper Amazon basin in Bolivia, western Brazil and eastern Peru. They weigh between 365 and 1135 grams and measure, from the head to the base of the tail, between 225 and 370mm. Black-capped squirrel monkeys are primarily tree-dwelling and are found in both native and plantation forests as well as some farmed areas near running water. Their diet is omnivorous and mostly consists of flowers, fruit, leaves, nuts, seeds, insects, arachnids, eggs and small vertebrates. They mostly live in female-dominated troops of around 40 to 75 monkeys, with males having been observed to disperse to live in all-male troops after reaching sexual maturation. Their current conservation status according to the IUCN is 'Least Concern'. The species belongs to the genus ''Saimiri'' and has two subspecies, ''S. b. boliviensis'' (the Bolivian squirrel monkey) and ''S. b. peruviensis'' (the Peruvian squ ...

Common Squirrel Monkey
Common squirrel monkey is the traditional common name for several small squirrel monkey species native to the tropical areas of South America. The term common squirrel monkey had been used as the common name for ''Saimiri sciureus'' before genetic research by Jessica Lynch Alfaro and others indicated ''S. scuireus'' covered at least 3 and possibly 4 species: the Guianan squirrel monkey (''S. scuireus''), Humboldt's squirrel monkey (''S. cassiquiarensis'') and Collins' squirrel monkey (''S. collinsi''). The Ecuadorian squirrel monkey (''S. cassiquiarensis macrodon''), generally regarded as a subspecies of Humboldt's squirrel monkey, had also been sometimes proposed as a separate species that had originally been included within the term "common squirrel monkey." Range and introductions Common squirrel monkeys are found primarily in the Amazon Basin. Before the taxon was split, it had been considered to be found within the countries of Brazil, Colombia, Ecuador, French Guiana, ...

Saimiri Vanzolinii
The black squirrel monkey (''Saimiri vanzolinii''), also known as the blackish squirrel monkey or black-headed squirrel monkey, is a small New World monkey, New World primate, endemic (ecology), endemic to the central Amazon Rainforest, Amazon in Brazil. It largely resembles the female of the far more common Bolivian squirrel monkey, though the latter lacks the black central back. This squirrel monkey has one of the most restricted geographical Range (biology), distributions for a primate, living in várzea forest in the confluence of the Japurá River, Japura and Amazon River, Solimões rivers. Its entire range is within the Mamirauá Sustainable Development Reserve. It resides in the reserve with two other Saimiri species. It is a social primate that travels with other black squirrel monkeys in large troops within its habitat. Its small size makes it an easy target for its predators; however, it may resist predators when it travels in large troops. Its species overall has posit ...

Saimiri Oerstedii
The Central American squirrel monkey (''Saimiri oerstedii''), also known as the red-backed squirrel monkey, is a squirrel monkey species from the Pacific coast of Costa Rica and Panama. It is restricted to the northwestern tip of Panama near the border with Costa Rica, and the central and southern Pacific coast of Costa Rica, primarily in Manuel Antonio and Corcovado National Parks. It is a small monkey with an orange back and a distinctive white and black facial mask. It has an omnivorous diet, eating fruits, other plant materials, invertebrates and some small vertebrates. In turn, it has a number of predators, including raptors, cats and snakes. It lives in large groups that typically contain between 20 and 75 monkeys. It has one of the most egalitarian social structures of all monkeys. Females do not form dominance hierarchies, and males do so only at breeding season. Females become sexually mature at years, and males at 4 to 5 years. Sexually mature females leave the natal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saimiri Sciureus
The Guianan squirrel monkey (''Saimiri sciureus'') is a species of squirrel monkey from Guiana, Venezuela and Brazil. ''S. sciureus'' formerly applied to Humboldt's squirrel monkey and Collins' squirrel monkey, but genetic research in 2009 and 2015 revealed that these are distinct species. Taxonomy Several now-separate squirrel monkey species were formerly considered a single species, ''Saimiri scuireus'', generally known as the common squirrel monkey, with a wide range in the northern half of South America. A 2009 genetic study by Carretero-Pinzón, ''et al'' indicated Humboldt's squirrel monkey, ''S. cassiquiarensis'', from Colombia, Peru and Ecuador, which had been considered a subspecies of ''S. scuireus'', was actually more closely related to other squirrel monkey species. A 2015 genetic study by Lynch Alfaro, ''et al'' revealed that Collins' squirrel monkey, ''S. collinsi'', from northeastern Brazil, which had also been considered a subspecies of ''S. scuireus'', shoul ...
