[4] The bald uakari is restricted to várzea forests and other wooded habitats near water in the western Amazon of Brazil and Peru.

n. If this is accepted by the wider research community, it could have large implications for the conservation status of the five species, for example with C. novaesi and C. amuna having small ranges at particular risk from deforestation.

[4] The arboreal bald uakari prefers to reside in seasonally flooded forests in the area of the Amazon River Basin, in the countries of Peru and Brazil.

[4] It is important that the uakari is arboreal (lives in the tree tops) because of the flooding of the forests and the water rising to great heights during the rainy season.

[2] Since it only lives in white water flooded forests, it is very susceptible to human impact (i.e. land acquisition for agriculture and/or pastures).

[19] Canopy disruption and forest loss directly affect uakaris because of their arboreal lifestyle and adaptations for seed food consumption.

Additionally, Cacajao calvus populations are located so close to the Amazon River that there is a higher risk of human hunting from canoes and such to use the primates as a food source or bait.

[18] Along with the AACP, Brazil's national environment agency, the Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA) is gaining help from the army to patrol the Amazon for acts of illegal logging, mining, and deforestation.
