O macaco de nariz dourado é um dos mais Imagine que você está em uma caminhada pelas florestas enevoadas e
montanhosas da China Central. Você ouve um sussurro repentino nas árvores acima de você. Olhe para cima, e
você pode apenas detectar um flash de ouro correndo através do dossel. Você acabou de ter um encontro raro com
o macaco dourado de nariz esnobrecido – uma criatura tão enigmática quanto está em perigo.
O macaco de nariz dourado tem um casaco de pele que é uma mistura impressionante de ouro, branco e cinza-
azulado. Esta magnífica pelagem permite tolerar a neve melhor do que qualquer outro primata. E não vamos
esquecer sua característica mais memorável: um nariz que é mais um nub, achatado contra o rosto.
Estrutura social extremamente complexa
A complexa sociedade de macacos de nariz esnobado – especificamente o macaco dourado de nariz esnovo – é um
assunto de fascínio por primatologistas e entusiastas da vida selvagem. Esses macacos vivem em intrincadas
hierarquias sociais completas com alianças, rivalidades e mudanças dramáticas no poder. Mas vamos dar um passo
a passo.
Comecemos pela organização básica. Macacos de nariz dourado vivem em sociedades multinível. No nível mais
básico, você tem a “unidade única masculina” (OMU), que compreende um único macho adulto, várias fêmeas
adultas e seus descendentes. Várias OMUs podem se unir para formar uma banda, e várias bandas formam uma
tropa.
As tropas também têm uma configuração social interessante e fluida. Conhecido como um aglomerado social de
fusão de fissão, grupos maiores (populações ou tropas) se desligam em grupos menores, dependendo das

Por exemplo, macacos de nariz dourado têm vários níveis de organização. No nível mais básico, esses macacos se
agregam em rebanhos ou clãs que consistem em um macho reprodutor singular, seu harém de fêmeas reprodutoras
e quaisquer juvenis e bebês associados.

However, multiple male social levels have also been documented. Bachelor males, mostly those who are yet to
breach the cusp of adulthood (read: juveniles and subadults), forage and shelter together. Most often these “bro
groups” are very literally fraternal units that are formed when the associated male offspring (brothers, half brothers)
from a fundamental level aggregation age out of their familial herd. Sometimes, an infant may grow up and instead
usurp dominance from the resident or dominant male directly, thus taking the reins of the fundamental aggregation or
herd that he was born into. 
Female monkeys also have their hierarchies within the OMU, often determined by factors like age, experience, and
sometimes lineage. The older or more experienced females typically enjoy better access to resources like food and
grooming from their male counterpart. Even the task of caring for the young is influenced by these hierarchies, with
higher-ranking females sometimes receiving more help in childcare from lower-ranking ones.
There’s also evidence to suggest that certain behaviors and preferences may be learned rather than instinctual,
indicating a rudimentary form of culture within these monkey societies. For instance, different troops have been
observed using unique techniques to access food or avoid predators.
An Old-World Monkey Struggling in a New World
But despite its remarkable adaptations, the golden snub-nosed monkey isn’t doing all that well. Like many Old-World
Monkeys, it’s struggling.
“Old World monkeys” is a term used to describe a specific group of primates that belong to the family
Cercopithecidae. These monkeys are native to Africa and Asia, and they differ from their New World monkey
counterparts, which are found in Central and South America.
Old World Monkeys New World Monkeys

Lack prehensile tails Possess prehensile tails 
Generally larger Generally smaller 
Have cheek pouches Lack cheek pouches 
Old World monkeys are versatile creatures, inhabiting a range of environments from grasslands to forests to
mountainous regions. You’ll find baboons gallivanting across the savannas of Africa and macaques mingling near
temples in Asia. Their adaptability is remarkable and speaks volumes about their evolutionary success. For instance,
golden snub-nosed monkeys are excellently adjusted to the tough environments of Tibet, which we’ll get to in a
moment.

What sets Old World monkeys apart? For starters, their noses are generally more downward-facing, and they often
have smaller, less flexible tails than New World monkeys. Some don’t have tails at all. You’ll also notice that Old
World monkeys usually have larger bodies and bigger brains in proportion to their size. But it’s not all good for these
creatures, and it’s not all good for the snub-nosed monkey.
The Golden Snub-Nosed Monkey is Found only in the incredibly fragmented temperate montane forests of the
Tibetan Plateau, and this old-world monkey may be losing its place in the new world. 
The Monkey who likes the cold
The golden snub-nosed monkey found its environmental niche in the cold.
Also known as Sichuan Golden Monkeys, these animals boast an ancient lineage. As proud members of the
Cercopithecidae family, they carry an old genetic heritage. 
There are actually three subspecies of this monkey, and they all have a long-standing connection with humans in
their habitats.
For local communities, the golden snub-nosed monkey holds a special place in folklore and tradition. They’re seen as
guardians of the forest, and their presence is thought to bring good luck. In a way, they are symbolic of the delicate
balance between humans and nature, a relationship that has grown increasingly strained over time.
This is where things take a darker turn. As captivating as they are, golden snub-nosed monkeys are critically
endangered. Habitat loss and hunting have decimated their numbers. Just a few decades ago, you could find troops
of these monkeys roaming freely. Now, only fragmented communities remain, confined to reserves and constantly at
risk.

Endemic to China, these primates can be found in only four provinces, Sichuan, Gansu, Shaanxi, and Hubei in the
central and southwestern parts of the country. Within these provinces as well, their presence is far from widespread.
These remarkable specialists are limited to elevations ranging from 1,500 to 3,400 meters above sea level and
exclusively inhabit forests characterized by either deciduous, mixed coniferous, or broadleaf vegetation. They can
only survive in these areas, and these areas are continuously exploited and fragmented by humans.

6/12Golden snub-nosed monkeys are “specialists” — they like environments for which they’re well adapted to. They’re
picky with their coniferous and broadleaf habitats. They reside in broadleaf habitats only at elevations above 2,200 m
and in mixed coniferous forests at altitudes above 2,600 m
Still, they’re not that picky. They’ve been observed in deciduous forests, mixed-leaf forests, and even high-altitude
coniferous forests. They have a diet that consists of leaves, fruits, seeds, and occasionally small animals, showing a
certain level of dietary flexibility.
It’s essential to note that while the golden snub-nosed monkeys are specialized in some aspects—like their social
structure and vocalizations—the key factors contributing to their endangered status are overwhelmingly related to
human impact rather than their biological specialization. They are capable of surviving and even thriving in their
natural habitats if left undisturbed.

This specialization explains, in part, why they’re endangered. Per the IUCN Red List, The Golden Snub-Nosed
Monkey is endangered. In fact, every subspecies of the Golden Snub-Nosed Monkey as well as every species of the
genera of Snub-Nosed Monkey is endangered.
The primary threats facing golden snub-nosed monkeys are habitat loss and fragmentation, often due to human
activities like logging, agricultural expansion, and infrastructure development. These activities reduce the size of the
monkey’s living space and separate populations, making it more difficult for them to find food, shelter, and mates.
Another significant threat is illegal hunting. Their striking appearance, particularly their golden fur, makes them targets
for the wildlife trade, both for their body parts and sometimes as exotic pets.
But their immediate concern has more to do with habitat loss now. Their range is quite small and they need dense
swathes of canopied landscapes in one stretch. 
But In spite of their endangered nature, currently, no specific species recovery plans or site recovery plans have been
enacted.

Predictably, these primates do not adhere to fixed home ranges but rather move seasonally among their diverse
range of habitats. But they’re very difficult to study.
The group in itself isn’t adequately researched. These monkeys exhibit a preference for higher elevations, thriving at
altitudes exceeding 4,000 meters (13,000 ft). Adding to the challenge for researchers, they not only contend with high
altitudes but also grapple with the monkeys’ seasonal movements. During the winters, these primates alter their
home ranges, venturing deeper into more remote and unfragmented expanses of forest to weather the cold months.
Researchers are working hard to understand how to best try to save these creatures. They use drone technology to
monitor populations and employ satellite tracking to understand migration patterns. The more we know about their
lives, the better equipped we’ll be to protect them. As researchers dig deeper, they’re uncovering surprising facts. Did
you know that these monkeys have different vocalizations for different types of predators? Such discoveries aren’t
just fascinating—they’re vital for conservation efforts.
As of now, the genus comprises just five recognized species:
1. Golden Snub-Nosed Monkey
2. Black-and-White Snub-Nosed Monkey
3. Gray Snub-Nosed Monkey
4. Tonkin Snub-Nosed Monkey
5. Myanmar or Black Snub-Nosed Monkey
However, there are many details we still don’t know about these fascinating monkeys.
Appearance
With an average length of approximately 68.0 cm (26.8 in) for males and 51.8 cm (20.4 in) for females, these
monkeys are the size of a standard backpack. 
While both genders rock the distinctive namesake hues of gold on their bellies, foreheads, and necks, they still exhibit
noticeable differences. Male golden snub-nosed monkeys don a contrasting dark grayish-black coat on the nape of
their necks, extending from their shoulders down to their arms, as well as on their heads and tails. In contrast,
females display these same areas adorned with a brownish hue.
On the contrary, infants and juveniles have brown or gray fur. As they progress through their development, juveniles
gradually acquire a reddish coat, which further transforms into the characteristic hues of gold that don sub-adults and
ultimately adults who have acquired full maturity.

Taxonomy 
Biologists have further classified the species into three different sub-species based on the lengths of their tails as well
as a few skeletal differences: 
1. Moupin Golden-Snub Nosed Monkey: The OG Sichuan snub-nosed monkey, sizable populations, of the sub-
species exclusively thrive in the high elevations of the Qionglai, Min, Daxiangling, and Xiaoxiangling Mountains
that abut the Sichuan Basin.

2. Qinling Golden-Snub Nosed Monkey: Sequestered in the Qinling Mountains in the Shaanxi province, around
4000 individuals of this sub-species reside in 39 troops. 
3. Hubei Golden-Snub Nosed Monkey: The smallest population of all three subspecies, there are only
approximately 1,100 subspecies (5-6 troops) of the Hubei Golden-Snub Nosed Monkeys isolated in the Daba
mountains of China. 
These three subspecies not only exhibit differences in physical characteristics but are also geographically distinct
from each other
Golden Snub-Nosed Monkey Facts
The Golden Snub-Nosed Monkey isn’t the only endangered species up in the hills of China; their range overlaps with
Giant Pandas in Sichuan, Shaanxi, and Gansu! This spatial overlap in range bodes well for both species as sympatric
conservation plans to preserve them can be devised. 
These monkeys love a good dead tree to munch on as their primary source of nutrition, lichen, is significantly more
abundant on dead trees than on live ones. Notably, this affinity for the dead is also what contributes to the limited
range of these animals as dead trees are harvested from their habitats as firewood or driftwood. 
The nomenclature of these monkeys offers a fun segue into Ottoman history. The specific epithet of the golden snub-
nosed monkeys, “roxellana,” is a nod to Süleyman the Magnificent’s consort, the original namesake!

Recent Studies on golden snub-nosed monkeys
In June 2023, scientists from a group of universities ( Northwest University in China, University of Bristol in UK, and
the University of Western Australia in Australia) surmised for the first time ever that odd-nosed monkeys (like the
golden-snub-nosed monkey) developed distinct and peculiar social organizations as a long-term adaptation in
response to their extremely cold habitats. 
The fascinating study revealed that colobines, a subfamily of the Old World monkeys, lived in colder climates
developed hormonal pathways that increased dopamine and oxytocin production thus boosting maternal care in
these primates. This meant that mother primates would breastfeed their little ones longer than non-colobine primates
and extend care for longer periods as well. All of this contributed to long term adaptive change that enabled
strengthened relationships between individuals in troops!

“Our study identified, for the first time, a genetically regulated adaptation linked to the evolution of social systems in
primates,” opined Dr. Kit Opie, a researcher from the University of Bristol opined in a news release dated July 1st,
2023. 
In the same release, Dr. Cyril Grueter explained that the study provided a unique perspective on the role of climate in
social evolution. 
“With climate change becoming an hugely important environmental pressure on animals, it is hoped that this study
will raise awareness for the need to investigate what course social evolution will take as the prevailing climate
changes,” said Dr. Grueter.

A special creature worthy of our attention
12/12
The golden snub-nosed monkey, with its peculiar name and even more peculiar morphological and social
adaptations, provides a captivating window into the new world of old world primates. Their unique ecological roles,
social structures, and adaptations to cold provide a unique perspective on the multifaceted nature of animal evolution.
However, with habitat loss and fragmentation encroaching upon their dwindling habitats, the golden snub-nosed
monkey’s future hangs in the balance. 
As the pages turn in our quest to know more about these beguiling primates, it’s evident that the clock is ticking for
the golden snub-nosed monkeys. The fragments of knowledge we’ve gathered only emphasize how much more we
have yet to learn. These complex, social creatures, with their rich hierarchies and unique adaptations to some of
China’s harshest climates, offer us a glimpse into a world that’s rapidly disappearing under the weight of human
encroachment.
But the story doesn’t have to end here, and it shouldn’t. Not when we know that targeted conservation efforts can
make a difference. The same drone technology and satellite tracking that have expanded our understanding can help
us create conservation strategies that are not only effective but also respectful of the monkey’s natural behavior and
habitat requirements. Additionally, their overlapping habitats with other endangered species like the Giant Panda offer
the opportunity for multi-species conservation plans, making every dollar invested work twice as hard.
In local folklore, the golden snub-nosed monkey is a guardian of the forest, a symbol of good fortune and the fragile
equilibrium between humans and nature. Perhaps it’s time to return the favor. Ensuring the survival of these golden
guardians isn’t just about saving another species from extinction; it’s about acknowledging the intricate web of life to
which we all belong. By investing in their future, we’re safeguarding our own. The next time you hear a rustle in the
treetops, may it herald not just the presence of this rare creature, but also a renewed commitment to the
extraordinary biodiversity of our planet.
