Zoo Report

The time interval that I analyzed this animal was from 11:30am to 11:50am and this monkey actually had a very active behavior and it was really a good experience to observe this monkey. The immediate physical description I was able to analyze from this primate was that it was black with a very long tail that later I was able to find out that it was actually a prehensile tail. The common behavior in this one was much walking and sitting during my analyzation. It was interesting to see the locomotion of this animal because I was able to see that it was both Quadrupedal and Bipedal. From the knowledge I have gotten from this class I know having that is a great advantage especially for the fact that it even uses it’s prehensile tail because it means they can travel for a much longer time compared to the primates that have only the locomotion of a quadrupedal. During my observation there was a point where the monkey was just prone on the cage and I thought it was almost going to pee on me because its genteel parts became very red so I stepped away from the cage. The primate at no time peed during my observation so that was a relief.

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.

After about 10 minutes, he is abruptly bothered by the youngster who is running on his knuckles towards the male and runs back up the hill as if he is taunting him. The youngster does it about 3 mores times within the next 7 minutes and perches upon the hill in the same position as the silverback, except he is bended at the knees in squat position. In my second visit, I return to the gorilla exhibit for about 10 minutes to see a female unknown if related to the previous observation in submission. She is found crouched to the floor with her elbows on the ground and hands extended out and her butt perched up. Her hind legs are also bent and position to help support her butt. Three minutes upon observation, a silverback male comes running on his knuckles from another part of the exhibit and mounts the female. He positions himself on his knuckles to provide him support and continues with the sexual intercourse, in which I conclude my observations.

-The bonobo is the most recently discovered great ape in modern times.  It was revealed in 1929 by German anatomist Ernest Schwarz that a skull once thought belonging to a juvenile chimpanzee was in fact a new subspecies of chimpanzee known now as the Pan paniscus, or bonobo. (Waal 6)  During the Pleistocene epoch approximately 1.5 million years ago, the Congo River was formed in what is now the Democratic Republic of the Congo. (San Diego Zoo 2)  The river geographically segregated groups and individual chimpanzees south of the river resulting in these chimps being reproductively isolated.  Allopatric speciation took place as a response to new

When it was born it behaved in the same assertive ways that male monkeys behaved. It challenged other males to fights, joined in rough and tumble games and tried to mate with female monkeys. Other studies of animals being injected with opposite sex hormones produced similar results. It is important not to generalise animal study findings to human beings who are very much aware of their behaviour and are able to control it.

Goodall, J. (1971). In the Shadow of Man. Boston: Houghton Mifflin. The author’s goal in writing this book is to discuss her experiences and what she had learned from studying wild Chimpanzees. Goodall wrote this book in order to convey her knowledge of a species of animal she loves very much, so that others may become educated and join her in protecting them. She dreamed of going to Africa to see them, and was offered a job by Dr. Lewis Leakey. Goodall wanted nothing more than a chance to help. Her experiences in surrounding herself with them have completely changed the way scientists conduct field research. Whether she intended to or not, the data she has collected has debunked myths and uncovered truths about chimpanzees, while bringing more light to human behavior.

Within this essay, we will study more in depth the behavioral as well as physical traits of two primates at a zoo from their interaction with their peers to their place in the group. This observation would enable us to further understand the possible existing correlation between humans and primates. First, I studied a female chimpanzee with her baby, and then, a dominant male gorilla, in San Francisco Zoo at about noon, on May 23, 2015, for an hour each. Even though they share some similarities such as having a large brain, living for a long time, and being bored in their enclosure, they are still different; when gorillas are the largest, chimpanzees are the smartest. In fact, chimps use tools to catch food, they would not be able to reach

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.

I observed a type of Ape known as the Western Lowland Gorilla. The scientific name for a Gorilla is the Gorilla gorilla. Gorillas are the largest of all living primates and at native to west central Africa. Gorillas exhibit sexual dimorphism within their species because males are very obviously much larger than females. The size of the gorillas came across very intimating and gave me an off impression of what this specie was actually going to be like. While observing the gorillas I noticed that these creatures are very slow, lethargic primates. Gorillas move quadrupedally by putting weight down on their arms and knuckles as they walk. They have hands and opposable thumbs, like humans, and are able to grasp things with a better grip. When Gorillas need to reach above themselves such as for leaves or branches they are able to stand on both legs while reaching. While resting Gorillas sit on their bottoms, legs to the side in a similar position that humans do. When resting I noticed that sometimes Gorillas like to take advantage of the moment by self grooming, using their hands. Gorillas usually have an herbivore diet but eat occasional insects. Due to their large body structure it is harder for them move around quickly so they do not need to eat foods that contain as much nutrients and proteins as smaller,

During my research of Orangutans and Mandrills I observed them in captivity at the San Diego Zoo. My observations included a 20 minute observation of each primate as it cohabitated with other Primates and with other members of its own species. My findings will support the research of Orangutans and Mandrills through firsthand observations.

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

I decided to look at the sexual behavior of bonobos because they are known for their frequent sexual behavior. Though they are not one of the types of great apes mentioned in the book, a bonobo is nonetheless a great ape that belongs in the same genus as the common chimpanzee. Furuichi et al. observed bonobos in their naturalistic habitat in Wamba, Democratic Republic

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.

Previously, I chose biological anthropology for one of my general education science requirements. As a class project, the professor gave us the incredible opportunity to study the primates at the San Diego Zoo. The assignment was to choose two primate species to focus on: one species from the old world and one from the new world. I decided to observe the tufted Capuchins and the Bornean and Sumatran orangutans. My classmates and I were to describe the primates’ appearances, behaviors, eating patterns, and to paint a picture of specific encounters that occurred during the time of our
