Blackish squirrel monkey, Black-headed squirrel monkey
The black squirrel monkey (Saimiri vanzolinii ), also known as the blackish squirrel monkey or black-headed squirrel monkey, is a small New World primate, endemic to the central 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 distributions for a primate, living in várzea forest in the confluence of the Japura and 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 positive effects on the economy.

starts withBlack squirrel monkeys are small primates. They have blackish-gray fur over most of their body except for their legs and stomach. Their legs can be yellow or have a reddish tint. Their stomachs will have a yellow tint. They have short and dense fur everywhere except for certain areas on the face. They lack hair in the areas of the nostrils and lips, and the skin is black in these areas. Black squirrel monkeys tend to be 27 to 32 centimeters in length not including the length of their tails. Their full length, including their tails, can be about 40 centimeters longer than their length without their tails. Male black squirrel monkeys range in weight anywhere from 0.64 to 1.22 kilograms (1.4 to 2.7 pounds). Female black squirrel monkeys have a weight range of 0.64 to 0.86 kg (1.4 to 1.9 lb).
Black squirrel monkeys reside within the Mamirauá Sustainable Development Reserve in Brazil. The várzea forest of this specific area experiences a consistent cycle of flooding. The patterns of rain can cause a typical buildup of around 35 feet of flooding in the forest. Atypical flooding due to excessive floods over a longer amount of time can threaten black squirrel monkeys' habitat.
They are interactive primates. They exist in large groups of 40–50, and can exist in groups as large as 500 monkeys. Travelling in big groups allows these monkeys to resist their predators more effectively. They have more eyes on their surroundings which allows them to more easily and quickly alert the pack if they sense danger. If the pack is big enough, the pack may be able to surround certain predators.
Breeding season falls between the months of September and November. During this season, the male monkeys with fattened stomachs are desired more by the female monkeys. A female monkey's pregnancy will last about 140 to 170 days, and the time of birth falls at the same time that rainfall and food availability are at their peaks.
The black squirrel monkey species is declared endangered because of their limited range in the várzea forest. The change in climate due to global warming is also affecting the lives of the black squirrel monkey species.
The black squirrel monkey is preyed upon by snakes, raptors, and felids.
This black squirrel monkeys is omnivorous. It prefers fruit and insects, but also eats leaves, flowers, seeds, eggs, and small vertebrates.
