The Diet And Foraging Behavior

Typically feed in the morning on high energy foods and decreases in the afternoon. Activity varies depending on main dietary component Frugivores spend more time foraging than folivores, which in turn increase energetic expenditure During times of scarcity, folivores increase the amount of time spent resting to digest mature leaves Some frugivores increase activity to find alternate food choices Ranging Patterns Overall frugivores have greater home ranges and daily path lengths than folivores. As the percent of foliage increases the time spent traveling decreases. Over lapping ranges may lead to competition between groups, especially when population density is high. Time and energy should be spent defending high quality food. Food Choice Increase in preferred, high quality foods during the wet season. Primates have a greater dietary breadth during the dry season. Consume more subsistence, although usually lower quality, foods during the dry season Grouping Patterns Large groups can monopolize resources better Monopolizing high quality food should increase female reproductive rate Females should have higher fertility Males should have access to more females with better fertility than males in smaller groups; therefore, increasing his reproductive success Less cohesive female grouping Greater benefit to forage on own – rather than defending a food patch and then not acquiring any food Maintaining a cohesive grouping

The capuchin monkeys are known as one of, if not the most intelligent monkeys of all New World species. They reside naturally in the forests of southern Mexico, the West Indies, and Central and South America, but can be found in zoos and captivity around the globe. Capuchins regularly eat fruits, insects, and nuts, and spend the majority of their day foraging for food. Capuchins travel and live in groups, residing in the treetops and canopy of the forest; however, the monkeys will travel along the forest floor as well. They have prehensile tails that are the same length as their body, have opposable thumbs, and primarily range from light to dark brown with white facial markings.

Not only did Jane discover their tool making abilities, but also they eat both plants and animals, such as bush pigs and termites (Goodall 1971). This fascinated many other primatologists because chimps were once thought of as herbivores. Jane also realized chimpanzees seem to express the same feelings humans do, though it is not certain (Goodall 598). Examples of such emotions are love, confusion, fear, and aggression. They often show love and care to

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

A bonobo’s diet is diverse and According to table 3 in The Apes: Challenges for the 21st Century, fruit takes up 55 percent of bonobos diet and 95 percent of their feces volume (Conklin-Brittain 2001, p. 167-174). Fruit is a staple in their diet, however, they also consume high-quality shoots, leaves, mushrooms, seeds, flowers, stems and pith

In this article, “What does variation in primate behavior mean?” the author, Karen Strier describes the general concept of intraspecific behavioral variation, in concerns towards the ability of primates of all species to change and adapt to benefit and increase their future survival rate. Her analysis details how “behavioral flexibility” within the primate world has been studied and understood for a long period of time, but now along with the addition of intraspecific behavioral variation, there is a realization of the potential threat to primate survival under new conditions including environmental influences.

Chimpanzees may eat nuts, seeds, and insects, such as termites and ants. They may also hunt and eat meat, but they have to watch out for leopards, because Leopards hunt for chimpanzees. Chimpanzees spend most of the time on the ground, they walk on all fours, using the soles of their feet’s, and the knuckles on their hands. They can also stand on two legs and may climb trees swinging from branch to branch. Chimpanzees live in multi-male and multi-female communities. Females may mate with many males and the males treats all offspring as if they were their own. Females have a bright pink bottom which lets the males know when the baby is fertile. A female chimpanzee are most likely to have her first child at about 14 years old. The pregnancy period takes about 8.5 months. The infants are dependent on their mother for about 5 years and females give birth to a new chimp at about every 5 years and may have about 4-6 children in her lifetime. Did you know the Robust Chimpanzee is one of the closest living relatives to us! Humans and chimpanzees share 98 percent of the same

A few years after the abandonment of the cacao fields, once cleared areas in the forests were allowed to grow naturally again. The monkey’s food supply increased even more. Suddenly, over a period of a few short years, the capuchin monkeys had a greatly increased food supply. The results of these boons were soon evident to Ewing and the others at Hacienda Baru. Previously, the monkeys were only seen with new

Chimpanzees are part of the non-human primate group. Though we share a common ancestor, evolution has pushed us in different directions. However this common ancestor causes humans to be curious about these creatures. As discussed in Jane Goodall’s video Among the Wild Chimpanzees we were once considered to be human because of our use of tools but once we observed these non-human primates using tools, this perception was changed forever. The question now at hand is if having the chimpanzees that we study in captivity makes a difference between studying wild chimps. These interesting creatures can be found naturally in the rainforests of Africa.

Gibbons eat a wide variety of foods. Their diet is comprised mostly of fruit, but also contains leaves, flowers and insects. Figs are the primary component of a gibbon’s diet, making up about a quarter of what gibbons eat daily. Depending on the availability and scarcity of other foods however, figs can be up to fifty percent of their daily intake. Diet varies by season and availability. For example, during cooler seasons the availability of flowers is higher, and during hotter, wetter seasons fresh fruit is more abundant. Regardless of the changes in availability however, fruit always comprises at least fifty percent of a gibbon’s diet. Beyond fruit, gibbons have been found to eat over one hundred different species of plants. Leaves, vines,

The capuchin monkeys all have some trademark similar features, with slight variation within each species.

In a physical aspect, chimpanzees are generally much smaller in size. The chimpanzee, which is approximately four feet high, weighs differently depending on gender. Males usually weigh 90 to 120 pounds, while females weigh between 60 to 110 pounds (“Chimpanzee”). Chimpanzees usually have a lifespan of roughly 50 to 60 years, depending on whether they are in captivity or the wilderness. Their body is mostly covered in black hair with the palms, ears, and face ranging from pale pink to black. Like humans, chimpanzees have flat faces, forward facing eyes, enormous ears, and relatively small nostrils. These features have significant implications on a chimp’s senses (Jane Goodall Institute). They have a short neck that connects to a bulging jaw, which is accompanied by large canines. These colossal canines help with their diet that mostly consists of nuts, leaves, meat, plants, and fruits. The male canines are notably huge compared to those of females, because male canines are used for

Palma et al. (2011) observed the habitat use, behavior, and ecology of two particular groups of red howler monkeys in the Colombian Andes. Palma et al. conducted focal sampling in order to examine the activity patterns and diets of the two groups. The groups’ habitats were tracked by carefully marking trees, and the howler monkeys’ activity patterns were split into five categories: feeding, moving, resting, social activities, and other. The howler monkeys’ diets were recorded by noting the species and types of plant matter (i.e., fruit, immature fruit, mature leaf, young leaf, flower, or bark) consumed by individual monkeys.

Chimps have some of the behavor of human beings. Chimps hug each other the way humans hug each others. Chimpanzees, who tend to resolve arguments with violence, will often kiss one another after a fight, just like humans. The bond between a mother and infant is often strong which is another behovir humans share. Chimps do quit a good number of significant that we also do, Including making tools.

As stated before, captive and wild captives can sometimes have different forms of tool kits. Some captive monkeys will use go other means for a tool of use such as a sponge. However, according to another study captive capuchins are also known to use bread as tool, as they use it as a sort of sponge for drinking water. However, it is possible that captive monkeys don’t always intentionally mean to use bread as a tool, but instead use this technique to soften the bread. Bread and sponges are essentially more used for “dipping tools” but still continually used and it is normal for captive capuchins to use food as a tool. In this same study, regions with wild captive capuchins, tool use was not only used for food, but it was also used as a transportation
