Bald-headed Uacari Cacajao calvus

Vulnerable

Brazil, Peru, Colombia

With their long shaggy coats and striking bright red faces, Bald-headed Uacaris are true icons of the Amazon rainforest and are found in Brazil, Peru and Colombia. When an Uacari has a bright red face this indicates good health, a pale face indicates a sickly physical state. These monkeys spend most of the year in the tree tops to avoid the seasonal flooding that is characteristic of their Amazonian habitat. During the dry season, they return to the ground to look for seeds.

A stunning bright red face and shaggy coat give the Bald-headed Uacari a fairytale quality. They live in the #Amazon #rainforest canopy and are vulnerable @IUCNredlist due to #deforestation. #Boycott4Wildlife

Unfortunately, low birth rates, habitat destruction and deforestation all threaten their existence.

These New World monkeys are very gregarious and social, they live in groups called troops of close to 100 individuals. They then split up into smaller groups of about ten monkeys to forage. At night they sleep aloft, high in the rain forest canopy.

The Bald-headed Uacari has a restricted range, from the confluence of the rios Japurá and Solimões. This taxon is a habitat specialist that is primarily limited to flooded forests such as the lower Rio Juruá or the white-water várzea habitats of the low Rio Japurú. The White Bald-headed Uacari is a highly specialized seed predator, fruits and seeds are the most important food item and just a handful of tree species made up the bulk of the diet (Ayres 1986).

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, scientists, conservationists, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail and industrial agriculture sectors and through strong campaigning we can stop them cutting down forests. Be bold! Be courageous! Join the #Boycott4Wildlife and stand up for the animals with your supermarket choices
