Bald Uakari

The Bald Uakari is a small New World monkey with a very short tail, red face, a bald head, and long coat. It generally weighs less than 9 pounds and is anywhere from about 20 to 23 inches in length.

Threats to Survival / Conservation Threats

The conservation status of this species was changed from near threatened to vulnerable in the 2008 World Conservation Union (IUCN) Red List because the species has declined at least 30% over the past 30 years (three generations) due to hunting and habitat loss. This is considerably better than the 1994 assessment which found them to be endangered, followed by the 2003 assessment which found the species to be near threatened. Although the conservation status has improved, actual population numbers are on a decreasing trend. Since these particular primates live only in white water flooded forests, they are very susceptible to human impact (ie: land acquisition for agriculture and/or pastures).

Forest loss and hunting are the two most prominent threats to Cacajao calvus. Between 1980 and 1990 it was found that an average of 15.4 million hectares of tropical forests were destroyed each year and the Neotropics are facing forest loss in areas such as the Southern and Eastern parts of the Amazonia. In 1997 the Amazon Basin experienced the highest rate of forest destruction of the remaining tropical rainforests worldwide. Logging of hardwoods is a major contributor to overall destruction as large-scale logging disrupts the continuity of forest canopies. Canopy disruption and forest loss directly affects uakaris because of their arboreal lifestyle and adaptations for seed food consumption. Additionally, Cacajao calvus populations are located so close to the Amazon River, there is a higher risk of human hunting from canoes and such to use the primates as a food source or bait.


In 1999, the Pilot Program to Conserve the Brazilian Rainforest, set forth by the World Bank, aimed to place a total of 350 million dollars from Germany, Britain, and other major industrialized communities into conservation programs for the Amazon. Conservation efforts have also been initiated by Wildlife Conservation Society representatives working in South America. The Amazon-Andes Conservation Program (AACP) was established in 2003 in order to protect a set of seven landscapes in the Amazon. These protected landscapes account for approximately three percent of the Amazon Basin. The Wildlife Conservation Society is planning on expanding to more landscapes in the near future. Along with the AACP, Brazil’s national environment agency, the Instituto Brasileiro do Meioambiente e dos Recursos Naturis Renovaveis (IBAMA) is gaining help from the army to patrol the Amazon for acts of illegal logging, mining, and deforestation.
