Macaco-de-cheiro

<em>Saimiri sciureus</em>, commonly known as the common squirrel monkey, is a small New World monkey in the family Cebidae, widely distributed across the tropical forests of South America. This species typically inhabits lowland tropical rainforests, riverine forests, secondary forests, and forest edges from sea level to approximately 2,000 metres elevation, showing a preference for lower forest strata and forest margins. Its geographic range spans the Amazon Basin, extending through Brazil, Peru, Colombia, Venezuela, Guyana, Bolivia, and adjacent countries. Classified as Least Concern on the IUCN Red List, <em>Saimiri sciureus</em> is among the most abundant primates across much of Amazonia, though local populations face pressures from deforestation and the pet trade. The species is highly social, typically forming troops of 10–75 individuals that forage actively during daylight hours. It is omnivorous, typically feeding on insects, fruit, nectar, small vertebrates, and bird eggs, with insects comprising a major proportion of the diet. Adults typically reach a body length of approximately 25–37 cm with a tail length of 37–47 cm, and body weight typically ranges from approximately 600–1,100 g. Average lifespan in the wild is typically around 15–20 years.
