The Buffy-headed
Marmoset
The Buffy-headed Marmoset or Callithrix flaviceps is a
critically endangered species that lives in Brazil. The species is the most
endangered of the marmoset species and as a result they are very rarely seen by
people. Once found all around the larger Rio area of Brazil, these monkeys are now
found only in select locations in a small area of Brazil.
The purpose of this essay is to bring awareness to the story of this primate
species, as well as to how and why we as humans should preserve nature. All primate
species help to tell the story of human and world history. If a population
becomes lost then the information that species can provide becomes very
limited. It is also important to note that other species have become adapted to
living a certain lifestyle over the course of millions of years. The rapid
destruction of habitats and resources has left many of these species unable to
adapt.
Buffy-headed
Marmosets are equipped with multiple unique features to help them better thrive
in their environment and make them important to the story of primates. All
Buffy-headed Marmosets have bodies that are black and grey with lighter yellow
and orange coloring on their tails, underparts, and faces. These marmosets are
very small but typical size for a monkey of the area as they weigh only between
119-710 grams and are only between 130-180 millimeters long.
Something unique about this species is
that it is sexually monomorphic in most instances. This means that males and
females are the same size, which is unique to marmosets.
They, as do most primates have fairly long lifespan that ranges 10-16 years. Buffy-headed
Marmosets are also genetically equipped and adapted to be able to communicate
in the treetops. They are considered very good communicators in comparison to
other primate species. Communication is done by creating different calls using
pitches and range, as well as various body postures.
Buffy-headed Marmosets are all also herbivores,
eating only plants such as fruits or various fungi, but have also been known to
eat caterpillars and frogs at times. It is also notable that generally
Buffy-headed Marmosets mate for life, although there are exceptions. It is a
notable practice, although because of this practice it is more difficult to
build the population back up to sustainable levels. Female marmosets typically
give birth to a maximum of two offspring, which in the wild is not a large
number. The increasingly more dangerous habitat of marmosets explains the death
of the old and young in this species.
If the offspring are hybrids, then the offspring
do not continue the genetic identity of the endangered Buffy-headed species. Hybridization
is the act of two species mating and creating offspring together. These hybrid
offspring do not carry the exact genetic makeup of the Buffy-headed parent and
are therefore not the same species. It appears as if Buffy-headed Marmosets
only interbreed with other species of Marmoset. Due to the very similar genetic
makeup, interbreeding between species of marmoset is viable. The three primary
species that Buffy-headed Marmosets breed with apart from their own are the Buffy-tufted,
Black-eared, and Common Marmoset. The interbreeding and hybridization occurs
between these marmoset species as a result of competition, habitat loss, human
interference, and many other factors. Nonetheless, hybridization is an important
issue in the marmoset community.
Also possible however is death due to human disruption or loss of home,
breeding, and feeding ground due to humans
or predators such as cats, snakes, and large birds.
Buffy-headed Marmosets also play an
important role in their ever-shrinking habitat. These Marmosets are known as
seeders. As marmosets are known for eating various types of plants, it is clear
as to how they spread seeds of plants through the process of consumption and
waste. These monkeys also feed on the gum of various plants, spreading seeds
that way as well.
As the marmoset population does this, the food availability remains consistent
as they essentially replenish the food sources themselves and other animals.
However, when outside factors such as human interference or natural disasters come
to be involved with the marmoset habitat, that can throw the ecological balance
off. These factors, along with the genetic and moral value of the Buffy-headed
Marmoset explain why it is crucial to preserve the habitat for this primate.
The primary reason for the endangerment of
the Buffy-headed Marmoset is deforestation that plagues much of the South American
continent. Most recently, the Brazilian government led by former president Jair
Bolsonaro from 2019 to 2022 removed a great number of protections for forests
and indigenous people. Bolsonaro once claimed that the “Amazon Rainforest
belongs to Brazil,” in his attempt to exploit the land. These policies have
sped up the destruction of many species of animals and plants, the Buffy-headed
Marmoset included.
According to the IUCN, despite
preservation efforts, the population of this Marmoset continues to drop for
various reasons. The decline is primarily attributed to logging, fire,
residential encroachment, and disease. As a result of these factors the
population of the Buffy-headed marmoset species is now estimated to be less
than 2,500 in the entire world.
Logging is a very lucrative practice in South America but is almost never practiced
in an environmentally friendly way. Much of the logging done in Brazil is
illegal, which is the most detrimental to the environment. This has resulted in
mass deforestation and the destruction of many acres of habitats home to many
species of animals.
Similarly, burning of land is a common
practice in agriculture. As humans move closer to wild populations, more
habitats are destroyed in this way. Another reason for population loss is
actually hybridization with other species of marmoset as stated in paragraph
four. Human encroachment on these primate habitats have pushed marmoset
species’ together, increasing the rate of hybridization. There are also
multiple biological reasons for population decrease although they are not
directly associated with humans.
There are a great number of threats that the Buff-headed Marmoset faces as the
species becomes more threatened every time territory and resources are
destroyed.
As it stands, the rate of population of
these marmosets is on the decline and are heading toward total extinction. While
the situation surrounding the Buffy-headed Marmoset is statistically
problematic from various points and may appear dire, it is my belief that with
the correct changes, the Buffy-headed Marmoset may be able to be saved. There
are already various groups and organizations that support the cause of saving
these primates.
The
Buffy-headed Marmoset is listed by the Convention on International Trade in
Endangered Species (CITES). This organization works with governments to protect
endangered animals like this marmoset, although the effectiveness of the
Brazilian government in this entire situation is questionable.
This government regulation is important however as the black market for stolen monkeys,
especially the Buffy-headed Marmoset, is incredibly detrimental to conservation
efforts. Likewise, it is impossible for a human to provide the specific and wide-ranging
needs of a marmoset that only their natural environment can provide.
One of the foremost conservation groups
supporting the Buffy-headed Marmoset is the Mountain Marmoset Conservation
Program (MMCP). The MMCP is a non-profit organization but has been working
tirelessly to preserve and replenish the Buffy-headed population. The MMCP
employs a variety of people, from biologists, to veterinarians, or whole zoos
in some cases.
This group also has teams of people who perform surveys and collect data,
important to the preservation and study of the species. The MMCP also invests
into breeding facilities as to control the hybrid population.
I believe that there are also other ways
that the Buffy-headed Marmoset can be saved and revitalized. Governments around
the world need to collectively agree to protect and preserve their precious
natural resources. This is an issue that goes beyond one primate species. There
needs to be however a collective effort to save these endangered animals. All people
should have the opportunity to be exposed to information about the actual
issues going on. If people have not heard of an issue, they cannot support it.
I believe issues such as this one should be more actively reported in the mainstream.
This is much more important than a fair amount of the things that are
commonplace in media. If there is a large amount of support for endangered
animals such as the Buffy-headed Marmoset, then perhaps it could spark real
government interest. At the same time, if information can spread in the media,
then groups like MMCP can be funded much more heavily by potential supporters.
At
the same time this exposure can be abused and inadvertently fuel the illegal
pet trade. That is why there is such a need for more protections, possibly
starting with revitalizing the importance of the matter to the Brazilian
government. As stated by Kappeler and Watts, dedication to long term research
is vital in the conservation attempts of primates.
This theory applies to any endangered species in the world in my view though. A
species of any living thing cannot be truly saved if it is not understood. Misinterpretation
and misinformation is what leads to even more destruction. The public should be
informed and educated on information regarding endangered animals and plants, like
the Buffy-headed Marmoset, so that the species and habitat can be saved
correctly and ethically.
Overall, the situation of the Buffy-headed
Marmoset is a prime example of the result of lack of human care for nature and respect
of other species. All primates are important to the story of human and world
history. These primates are our cousins and closest relatives. Their unique
genetics tell us more about our ancient origins than humans ever could
themselves. These are highly intelligent beings with numerous things being discovered
about them constantly. Humans have recorded as well as destroyed more history
than any other creature. It is our turn to take care of this world we call
home, starting with our endangered animals like the Buffy-headed Marmoset.
