Zoo Project

As part of the only Old World Monkey group I analyzed the Silver Langur whose scientific name is Trachypitneus Cristatus. In this cage there was a total of 6 monkeys so there was very much activity. This

A few weeks ago, I spent a lovely Monday afternoon observing two different primates at the Santa Ana Zoo. I got to the zoo around two in the afternoon, and to my surprise, the zoo was decently crowded. The Santa Ana Zoo is smaller in comparison to other zoos like the Los Angeles Zoo, but still had a decent amount of animals there. Covering a small 20 acres of land, I came across two primates that fit perfectly for the purposes of this course project. I chose to observe an endangered ape, the white-handed gibbon, and an endangered new world monkey, the golden-headed lion tamarin.

Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.

I primarily observed three orangutans, one male, one female, and one juvenile, of Sumatran and Bornean descent, scientifically known as Pongo abelli and Pongo pygmaeus, respectively, and to a lesser extent, two gibbons known as siamangs, or Symphalangus syndactylus. These primates share the same enclosure in the San Diego Zoo in California. I observed the orangutans from 12:58 P.M. to 2:00 P.M. CST on September 19th. During this time frame, the three orangutans mainly stayed high up in their man-made structures, consisting of multiple metal bars covered with nets, ropes, and hammocks. The female and juvenile orangutans stayed above ground from 12:58 P.M. to 1:31 P.M., and again from 1:48 P.M. until 2:00 P.M, approximately 45 minutes. During

Zoos present a certain blend of nature and culture. They have always provided a way to bring natural wildlife and urban Americans together as a means of entertainment. Yet, throughout the years the role of zoos have changed. Though once used for amusement, zoos are now being used for education on preservation and the welfare of endangered species. One may wonder where and how the idea of zoos started and just how they, and the environment around them, have changed throughout history.

Isbell and Wright’s articles both focus on monkey species and their native environments, Africa for Isbell’s (1994) vervet Old World monkey and South America, Peru area, for Wright’s (1994) owl and titis monkeys. The articles main focus is the relationship between these monkeys and their natural predators. Focusing on how the predator aspect of their lives is determined by their environment and adaptations they make to ensure survival. Isbell’s Vervets Year of Doom focuses more on the adaptations that was forced upon the vervets’ because of their changing environment, the death of fever trees. While Wright’s Night Watch on the Amazon focusses more on how the primates way of life affects their relationship with predators and the likelihood of attacks. Both articles have similar aspects however the species way of life, specifically their environment and sleep schedule, are quite different as well as the authors way of observing and studying the primates within their habitats.

This paper aims to study the traits of non-human primates. By observing two types of primates including Common Squirrel Monkey (Saimiri sciureus) and Western Gorillas (Gorilla Gorillas), I try to find out their characteristics, pattern of their behavior, and differences between these two primate species. Especially, characteristics and behavior such as social interaction, food acquisition and intelligence will be discussed and compared in this paper. In order to enhance the persuasiveness of my observation, I recorded and examined at least 25 distinct characteristics of both Common Squirrel Monkeys and Western Gorillas. It is also helpful for me to compare these two primates. Apart from exploring the primates’ traits and differentiation between them, this paper will discuss the effects of captivity. How being in captivity and on display in a zoo would influence their behaviors and emotions? The observation was a great success and I have successfully derived with a hypothesis base on our observing data. The ultimate goal of this paper is arousing humans’ awareness of the importance of studying primates.

They are clean primates that like grooming, and while observing them in the morning they would groom each other for about 10 minutes. They clean the hair of one another using their fingers. Just like any other primates, the Siamangs also do sleep, and based on the observation that I had they sleep for up to around 8hours. They sleep alone with one individual hurdled on each other on the tree trunk, sitting up right. The male and female have a

The first focal animal I chose to observe was a female adult spider monkey named Gumbelina who was sitting with a few of the other monkeys that were all sitting and grooming each other. She seemed to be very relaxed and won’t

This project pertains to the pygathrix cinerea or which it is more commonly know as the grey- shanked douc Monkey . It falls under the animalia kingdom, the chordata phylum, the mammalia class, the primates order, and the cercopithecidae family, the pygathrix genus,and the pygathrix nemaues species ( http://www.departments.bucknell.edu ). The body, and the majority of the arms, and lower legs are light grey with a paler underside, and their shoulders, upper legs, and part of their buttocks are marked with white patches. Their feet and hands are black while having the bare skin on their face being yellowish brown, and the areas around the mouth and chin which is white. Long white fur borders the sides of their face with a slanting eye, and their throats are white with an orange collar encircled

For the primate observation project I went to the Santa Barbara zoo to observe and contrast different types of primates. I observed one species of an old world monkey, which was a gorilla and two different species of new world monkeys, which were the Bolivian Grey Titi Monkey and also the Golden Lion Tamerin.

The other adult female that would be my focal point did emerge but remained less social and more timid than the other orangutans but was also younger. The orangutans as supported by San Diego Zoo Orangutan website would use all four limbs to move about the trees and would occasionally walk on the ground bipedally and using its long arms for support. One of the more curious observations was the interaction between the non-human primates and the humans which seemed to stem of curiosity on both sides. For instance at one point before the focal observation an adult human female with her infant were tapping on the glass of the enclosure and the adult human female began to pull things from her purse and show it to the orangutan who was leaning on the glass barrier; among many of the items was a bag of chocolate candies which the orangutan did not particularly respond to. The eldest adult female orangutan however seemed to respond very curiously and attentively to any infant or child that approached the enclosure.

For the Orangutan in the zoo each enclosure they had a total of three orangutan in each pen, most were all adults, except one which was a young juvenile. As well as it is appear to be that none of these orangutan are a part of a subgroup because some, if not all isolated themselves from others. In which is very common according to Lang C. (2005), "Adult males and independent adolescents of both sexes range alone while adult females range with their dependent and weaned offspring" (Primate Factsheet pongo, para. 1). So the zoo's orangutan act very similar to the wild ones. Next the differences is how are they physically built between in each others. For the orangutan, if they are standing they are about 5 feet tall, however including arm and leg span due to how they are built to climb and swing to places their body size will be seven feet tall. Another difference was that they had no tail due to they ancestors evolution to who they are now, which remove the chance of having the ability to have a prehensile tail in the process. The last physically difference is their hands. They have all fingers and thumbs, but they don't use their thumbs to grab; they use mostly their fingers to grasp objects. Which make them who they are

Last week I had the opportunity to visit the Los Angeles zoo on a beautiful, sunny Thursday (October 19th). Although I arrived off schedule which left a minimal amount of time to observe primates, I managed my time well. After being told that the larger animals get put away earlier, I figured my first stop would be at an ape enclosure. The ape I chose to see that day was the gorilla. The time that I began my observation was at approximately 3:05. At that time only one ape was quite visible and he was sitting at the front making eye contact with me making it seem as if he is HABITUATED. Next, post gorilla watching, I had the chance to take a gander at the ring railed lemurs at 3:40. These prosimians all had their own personalities which interested me deeply. Lastly, and certainly not least on my journey through the LA zoo, I had the chance of looking at the mandrills which were once classified as baboons. Considering that two baby mandrills were present and only a month old, this was my favorite exhibit to see because of their high energy and randomness of actions.

Since approximately 1250 B.C., ancient Egyptians had created and practiced the capture and display of animals in what are now known as zoos (Fravel). Records describe such exotic animals as birds, lions, giraffes, and tigers in captivity (Fravel). Since then, zoos have continued to entertain millions with the exciting chance to view exotic animals up close and personal. Even in ancient Greece, exotic animals were on display in fighting arenas, and in enclosed viewing areas. Originally in America, zoos were just created so that royalty and the wealthy could flaunt their exotic animals to the public (Leolupus). Today, with species threatened and habitats disappearing worldwide, zoos are serving a new purpose other than the mere exhibition of
