The Phayre's Leaf Monkey
Transcript of The Phayre's Leaf Monkey
What Do They Eat?
The Phayre’s Leaf Monkey is a type of herbivore called folivore. A folivore is when a species diet is mainly leaves( that's why its called the Phayre's Leaf Monkey). This monkey is known to eat leaves from approximately 80 different plants. The leaf monkey eats bamboo shoots, flowers and bark when leaves are not available. Since leaves have high amounts of cellulose ( stuff found in plants) and toxins (meaning extremely harmful) their stomachs become highly adaptive (able to change to fit their lifestyle). The Phayre’s leaf monkey spends over 75% of its time eating on the tops of trees.
The Leaf monkeys come in different colors. The typical leaf monkey is a greyish-blue with a brown side and in general their head and tail is darker than the rest of their body. The area around the eyes and lips are mostly white. Before they are 3 months old they are a yellowy orange color. Adult leaf monkeys tend to have longer hair at the top of their hair the babies do. The interesting thing is that female leaf monkeys have a tendency to be taller than males but males are heavier than females. Males heights range from 1.07-1.11 meters whereas females range anywhere from 1.3-1.15m. Their tail includes 65% of their overall height. A typical male would weigh about 7.4 kg and a female 6.2 kg.
Where Are They Found?
The Phayre's leaf monkey is found in areas such as Thailand, Bangladesh, India, Burma, China and Vietnam. These places have a very warm climate. These species live in primary and secondary forests. In India they are found in a secondary forest with dense bamboo sticks and few trees. In Bangladesh they are found in semi-evergreen forests and semi-deciduous forests. You will also find these monkeys in Vietnam’s national park. In Burma the place you might find them is in high forests or Bamboo forests alongside of hills and banks of water. Lastly in Thailand you would most likely find them in evergreen forests 15-50 meters off the ground. Basically they like to live high of the ground( like most monkey’s) and live in places with great amounts of density.
The main reason why Phayre’s Leaf Monkey is endangered is because of habitat loss( lost their homes). People are building things where their homes should be. Pollution around them is also an issue which has to do with people building factories near them. Predation by humans and other animals are slowly decreasing the population. Baby monkeys are more prone to get killed by other animals. The humans that live in the areas hunt them for meat and medical reasons. People are benefiting from this now but don't realize the consequences that may follow.
Why Are They Endangered
What Happens If They Go Extinct?
The Leaf Monkey has a similar mating system to a species called the Langur Monkey. They have a dominant male which mates with multiple females this system is called polygyny. The females usually give birth during the months of March and April and takes about 205 days to get the baby (only one are born at a time). Newborns are at the care of their moms for approximately 1 year which takes up a decent amount of energy. A typical Leaf Monkey's life span is 20-30 years. But overall their day to day life is pretty simple and boring.
What Can Be Done?
The Phayre's Leaf Monkey
Where possible to not build factories, houses and mills close to their homes. Governments could designate parks and sanctuaries for them. Stricter laws and penalties can also be put into motion for those that break the law. Greater publicity and awareness regarding this situation should also be made. It is extremely essential to save them because they are important for our ecosystem (seed dispersal, medication, food etc). The population is decreasing but is not critically endangered yet. I personally think that others should take more initiative to save these Monkeys.
The leaf monkey is really interesting because they use their vocals a lot. Males normal sounds are high-pitched(kah,kah) whereas when a predator is approaching its more softer (whoo,whoo). When a young Leaf Monkey is in trouble it sends a distress call and Females use a "lost call" to find their new borns. Lastly like I mentioned before they have white circles around their eyes which is a special feature.
Since the Phayre’s Leaf monkey plays an essential role in seed dispersal that would be a negative impact on the ecosystem. I personally think if they weren’t around to disperse the seeds it would change a lot around them. If they were to go extinct the hunters using the Leaf Monkey would have to find a new source of food and medical resources which could be a dilemma for people who depend on them. Also their extinction would cause an imbalance in our food chain because all the things eating them would might not be able to provide themselves with the resources they need. Lastly Leaf Monkey consumes a high amount of plants therefore it would cause an change in the places where they live.
You can distinguish(tell the difference) a female from a male by looking at the white circles around their eyes. A males is lined up to the sides of their nose creating a straight black line. But females white circles bend inwards creating a triangular shape
