Yellow-breasted capuchin biology

The yellow-breasted capuchin is a social monkey that lives in groups, thought to be of approximately 10 to 30 individuals, usually with more males than females. Spending most of their time in the trees, they forage during the day for fruit, nuts, flowers, young shoots, eggs, young birds, insects and spiders. This monkey exhibits an advanced behaviour that it learns from others in the group – it cracks nuts open by smashing two together or by hitting them against trees. The group communicates through barks, growls, screams, chatters, trills, twitters, purrs, whistles and warbles (5).

Females are sexually mature at four years, and males at seven or eight years. Gestation lasts 180 days and females give birth to just one offspring at a time (5).

The yellow-breasted capuchin is seriously threatened with extinction and the population is still declining. Not only is the very limited range of this monkey being reduced due to deforestation, but the yellow-breasted capuchin is trapped for the pet trade and hunted for meat (6).

Yellow-breasted capuchin conservation

Some protection of this species is achieved as a result of its presence in the Una Biological Reserve, the Condurú State Park (2), and at two biological research stations. A survey of this species is being conducted, believed to be among the rarest of Neotropical primates (2), but numbers will continue to decline unless the habitat of the yellow-breasted capuchin is protected (6).
