Saimiri Oerstedii
Central American Squirrel Monkey
Tropical rainforests, particularly in areas with dense canopy
The Central American Squirrel Monkey, saimiri oerstedii, is a small and vibrant primate native to the tropical forests of Costa Rica and Panama. This species is distinguished by its bright fur, with a back of olive or yellowish-green and a white or yellowish belly, creating a striking contrast. Adults weigh between 500 to 1100 grams, with a body length of approximately 26 to 36 cm, not including their long, bushy tail which adds an additional 35 to 42 cm. Their face is framed by white fur, with black around the mouth and eyes, giving them an expressive appearance.
| Population: | Listed as Vulnerable due to habitat loss and fragmentation |
| Generation Length: | 5-7 years |
| Average Weight: | 750-1100 grams |
| Average Length: | 26-36 cm, with a tail length of 35-42 cm |
| Lifespan: | 15-20 years in the wild |
| Diet: | Varied, with a preference for fruits and insects |
| Conservation Status: | Endangered (EN) |
Saimiri oerstedii thrives in primary and secondary forests, as well as in mangrove habitats. They are diurnal and arboreal, spending most of their time in the lower and middle levels of the canopy. These monkeys are highly social animals, forming large mixed-sex troops that can number over 70 individuals, although smaller groups are more common. The structure of these groups helps protect members from predators while foraging.
The diet of the Central American Squirrel Monkey mainly consists of fruits and insects, with occasional consumption of seeds, leaves, and small vertebrates. This varied diet reflects their role as both seed dispersers and controllers of insect populations in their ecosystem. Their foraging behavior is crucial for the regeneration of their forest habitats.
Reproduction in this species is seasonal, with births typically occurring at the start of the rainy season when food resources are most abundant. Females give birth to a single offspring after a gestation period of about 5 to 6 months. Infant care is primarily the responsibility of the mother, although other females in the group may also assist.
The population of the Central American Squirrel Monkey is considered vulnerable, facing threats from habitat destruction due to deforestation, agricultural expansion, and urban development. Conservation efforts are focused on habitat protection and restoration, along with research and monitoring programs to better understand their ecology and needs. The survival of Saimiri oerstedii is crucial for maintaining the biodiversity of Central America's tropical forests.
