Pied Tamarin Saguinus bicolor
Pied Tamarin Saguinus bicolor
Critically endangered
Brazil
The Pied Tamarin lives in primary forests and in small fragments of secondary forests. In primary forests like Reserva Ducke the density is lower than in small fragments (Gordo 2012). They eat fruits, nectar, plants and animal prey (including frogs, lizards, eggs, small birds, spiders and insects). They live in extended family groups of four to 15 individuals. They are critically endangered from palm oil, soy, meat and gold mining deforestation throughout their range.

Name, IUCN Status, and Locations
Pied Tamarin Saguinus bicolor
Red List: Critically Endangered
Locations: Brazil – restricted to the forests surrounding Manaus in Amazonas, north of the Rio Amazonas and east of the Rio Negro.
Mist rises over the fragmented forests around Manaus, where the Pied Tamarin clings to survival in one of the smallest and most threatened ranges of any primate on Earth.
Pied #Tamarins are fascinating and vibrant black-faced #monkeys with a shock of white fur around their muzzle and chest and expressive brown eyes. They are found only in the shrinking forests of Manaus, #Brazil. As bulldozers carve roads and cities sprawl, their home is being destroyed for #palmoil, #soy, #beef farming, #gold #mining, and relentless urban expansion. These tamarins also face threats from disease, predators, and the illegal pet trade.

Appearance and Behaviour
Pied Tamarins are instantly recognisable, with their hairless black faces, large “bat-like” ears, and fluffy white bodies contrasting with dark brown hindquarters and tails. Males and females look alike, measuring 20–28 cm in body length with tails up to 42 cm, and weighing around 400–450 g. Their hands and feet end in sharp claws, not nails, perfect for gripping branches and extracting gum from trees. Groups range from 2 to 15, led by a dominant female who is the only breeder. Their society is matriarchal and highly cooperative—males and siblings help care for the young, carrying twins through the canopy. Pied Tamarins are avid communicators, using a rich repertoire of chirps, trills, and even ultra-quiet “tsê” signals, some so soft that only spectrograms reveal them. They scent-mark their territory and use long calls to warn rivals or find lost group members. Curious and clever, they navigate a world of danger—dodging power lines, dogs, cats, and the ever-present threat of capture.
Threats
Deforestation and habitat fragmentation
The Pied Tamarin’s forest home is disappearing fast as Manaus expands. Palm oil, soy, beef, and gold mining drive relentless forest clearing, leaving only tiny, isolated patches. Urban sprawl and pollution make survival harder, and even protected areas are shrinking. Food is scarce in these fragments, and social groups of pied tamarins are split apart. With over 80% of their range set to vanish in less than two decades, extinction in the wild is a real risk.
Infrastructure projects and roads
New roads and power lines slice through the remaining forests, forcing Pied Tamarins to cross dangerous open spaces. Many are killed by vehicles or electrocuted on wires. Construction brings more people, noise, and pollution, making the forest even less safe. These projects also open the door for more logging and poaching, speeding up the loss of habitat.
Illegal pet trade and human persecution
Pied Tamarins are captured for the illegal pet trade, with infants sold in markets and many dying from stress. The pet trade tears apart family groups and leaves survivors vulnerable. Some tamarins are also hunted or killed as pests, and wildlife protection laws are poorly enforced. Every animal taken from the wild pushes the population lower.
Competition with golden-handed tamarins
Golden-handed tamarins are moving into Pied Tamarin territory and outcompeting them for food and space. These rivals thrive in disturbed habitats, pushing Pied Tamarins into smaller, less suitable fragments.
Predation by domestic dogs and cats
Wild cats, birds of prey, and snakes hunt Pied Tamarins, but domestic dogs and cats are now major threats in urban areas. With less forest cover, tamarins are easier targets. Every attack can break up a group and make survivors more cautious and isolated.
Disease
Pied Tamarins are highly vulnerable to a range of diseases, especially in fragmented habitats near cities. They can contract toxoplasmosis from stray cats and rodents, which can be fatal and has caused outbreaks in captive tamarins. Callitrichid hepatitis, caused by lymphocytic choriomeningitis virus (LCMV), is another serious threat, leading to sudden deaths in both wild and captive populations. Chronic diarrhoea and weight loss, often linked to marmoset wasting syndrome (MWS), are common in captive groups and associated with changes in gut bacteria, including overgrowth of Helicobacter and Lactobacillus species. Pied Tamarins also face risks from colitis and septic infections like tularemia, as well as general vulnerability to new pathogens introduced by domestic animals and humans.
Diet
Pied Tamarins are omnivores, feasting on fruits, nectar, flowers, plant gums, insects, spiders, frogs, lizards, bird eggs, and even small birds. Their sharp claws and teeth are perfect for gouging tree bark to extract gum, a crucial food in the dry season. By eating a wide variety of foods, they help disperse seeds and control insect populations, playing a vital role in the forest ecosystem. In captivity, they are sensitive to diet changes, and breeding success is linked to proper nutrition.
Reproduction and Mating
Pied Tamarins live in female-led groups, with only the dominant female breeding. She releases pheromones that suppress the fertility of other females. Mating is polyandrous—the dominant female mates with several males, and usually gives birth to twins after a gestation of about five months. The whole group helps raise the young, with males and siblings carrying infants and returning them to the mother to nurse. Breeding occurs mainly from March to May, but can happen year-round. In the wild, lifespan is uncertain but likely less than 10 years due to constant threats; in captivity, some live over a decade.
Geographic Range
The Pied Tamarin’s range is one of the smallest of any primate, limited to the forests around Manaus, north of the Rio Amazonas and east of the Rio Negro. Surveys show they rarely occur more than 35 km from Manaus, and are now absent from much of their former range due to deforestation and competition with golden-handed tamarins. Their last strongholds are small, degraded forest patches, some less than 10 hectares, surrounded by roads, suburbs, and farmland. Even in protected areas like Adolfo Ducke Forest Reserve and Sumaúma State Park, their numbers are falling as the city expands.
FAQs
What is the current population of the Pied Tamarin?
The Pied Tamarin population is estimated at fewer than 500 mature individuals in the wild, with a projected decline of over 80% within the next 18 years. Most groups survive in tiny, degraded fragments, often below the threshold needed for long-term survival. Captive populations exist, but breeding is challenging and does not offset wild losses. The National Action Plan aims to secure at least eight viable populations, each with at least 500 individuals, but this goal remains distant. Without urgent, large-scale habitat protection, extinction in the wild is a real risk.
How long do Pied Tamarins live?
In the wild, Pied Tamarins likely live less than 10 years due to predation, disease, and urban hazards. In captivity, some individuals survive over a decade, but stress and poor diet can shorten their lives. Females can breed from about two years old, but only the dominant female in each group reproduces. The high infant mortality rate in fragmented habitats further reduces average lifespan. Captive breeding programmes have had limited success, with many infants failing to survive. The constant threat of electrocution, road kills, and attacks by dogs or cats makes wild survival especially precarious.
What are the threats to the Pied Tamarin’s survival?
Pied Tamarins face a perfect storm of threats: rampant deforestation for palm oil, soy, beef, and gold mining; relentless urban expansion; direct competition from golden-handed tamarins; and daily dangers from dogs, cats, disease, and electrocution. The illegal pet trade rips infants from their families and fuels further decline. Fragmented habitats mean less food, fewer safe nesting sites, and higher stress. Even protected areas are under pressure as Manaus grows. Climate change and environmental instability only add to their vulnerability. Every threat is magnified by their tiny, shrinking range.
Does the Pied Tamarin make a good pet?
No absolutely NOT. Pied Tamarins are highly social, sensitive primates who suffer extreme stress, loneliness, and early death in captivity. The illegal pet trade destroys family groups, causes immense suffering, and drives the species closer to extinction. Captive tamarins often develop health and behavioural problems, and most do not survive long. Removing tamarins from the wild for pets is illegal and unethical, and fuels the ongoing decline of the species. The best way to help is to support indigenous-led protection of their habitat and refuse to buy wild animals as pets.
What can you do to help the Pied Tamarin?
You can make a difference by boycotting palm oil, soy, and beef products linked to Amazon deforestation. Refuse to buy gold mined from the Amazon, and never support the illegal pet trade. Support indigenous-led conservation and agroecology projects that protect and restore the forests around Manaus. Share the story of the Pied Tamarin to raise awareness and pressure governments to enforce habitat protections. Advocate for urban wildlife corridors and safe crossings to reduce road kills and electrocutions. Every action you take helps keep the forests alive for the Pied Tamarin and countless other species.
