Curious, social and beautiful White-Nosed Sakis live in the canopies of Brazilian Amazonia. They are vulnerable from human-related threats including palm oil, soy and meat deforestation, mining and human persecution. Fight for their survival every time you shop and be #vegan #boycottpalmoil and #Boycott4Wildlife

White Nosed Sakis have a range throughout the south-east and south-central regions of the Amazon Rainforest which extends into the country of Brazil. Their range overlaps with the Uta Hicks bearded saki throughout the southern Amazon which means that they compete for food with this other species, leading to a lack of food availability. They have also been recorded in the area south-west of the Dos Marmelos river in Brazil.

Appearance & Behaviour

Distinctive White Nosed-Sakis have tufts of long hair on their heads and beards, along with a long silky tail. Despite their namesake, they don’t have a white nose. All over they have black silky fur and a reddish pink nose. Females and males look similar, although females have a shorter and thinner tufts and beards.

Young White-Nosed Sakis use their tails to swing through to the jungle canopy. As adults, these tails become non-prehensile and are only used for balance. Their teeth are canine in appearance and are able to bite through the tough shells of fruits and seeds.

Males weigh around 2.5 to 3kg and females weighing slightly less than this, averaging about 2.5kg. They range between 35-45 cm in body length. Their sleek bodies and long tails for balance and support make them agile and fast moving climbers and leapers in the Amazonian jungle.

White-Nosed Sakis are most active and socialise throughout the day. Groups of around 20-30 individuals congregate together for sleeping and food gathering but then separate for other activities.

They generally communicate using sound and have higher pitched alarm calls during times of getting each others attention to warn of danger. Lower pitched sounds are reserved for more relaxed periods of eating and socialising. They have been recorded to wag their tails as ways of communication. Other methods of communication remain under-investigated.


The main threats identified for the White Nosed Saki are deforestation, forest fragmentation through logging, cattle ranching, agriculture, rural settlements, subsistence hunting, improvement of road infrastructure and the construction of hydroelectric dams.


Threats include:

  • Environmental destruction and deforestation for agriculture: beef, soy and palm oil.
  • Infrustructure development including hydroelectric dams and mining.
  • Human persecution and hunting. Their tails are used for cleaning dusters.

It is estimated that up to 30% of their range is threatened from agriculture.


The White-Nosed Saki competes with other Chiropotes over food supply. They prefer to live in forests with little or no human disturbance and are able to organise in groups to forage for food. They are relatively flexible in terms of habitat preference, which will depend upon food availability. They prefer to live in the shaded comfort of upper forest canopies which provide shade, nutrients and protection from predators. This is where they are most observed spending their daily lives.


These monkeys are not fussy and have been known to consume 100’s of different plants in Brazilian Amazonia. In general, they are foraging frugivores and their diet consists of seeds, fruit, bark, insects, leaves and flowers. The majority of their diet consists of seeds and fruit, with insects being eaten around 10% of the time. Fruit is preferred in its unripened and immature state as a major source of protein and fibre.

Mating and breeding

The mating and reproduction of the White Nosed Saki is an under-researched area. Observations show them to be seasonal breeders who give birth during spring and autumn. The gestation period has been studied and occurs over a period of five months. Studies indicate that only one infant is born each year to a mother, this is followed by a period of close maternal care and observation. More research is needed to reveal more detail.

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!
