what does the sumatran orangutan eat
Orangutans are found on only two islands in the world: Borneo and Sumatra. In Sumatra, they use small branches to build tools and use them to extract honey and seeds from difficult places. There are spikes on these fruits and their skin is also very hard. In this lesson, you'll learn about the habitat of the Sumatran orangutan, and how its habitat is disappearing. Mosquitoes are pests for orangutans as they are for humans, and orangutans use branches to swish them away. Recent political instability in the area of their habitat has led to increased illegal logging in areas that are protected, and increased capture of infants to be sold for the illegal pet trade. They use their teeth to tear and grind the food. courses that prepare you to earn In Sumatra this rarely happens and may be linked to sharing their habitat with the Sumatran tiger. However, it can be found at higher altitudes, with a few small populations known to exist above 1.000 m over the sea. They are not very territorial, sharing their home ranges with others, sometimes feeding alongside other orangutans around especially abundant fruit trees. Their body is usually smaller. Males who are not yet fully mature tend to associate with other females, particularly adolescent females, but are not usually aggressive. Once the fruit is safe, the ape will eat the seeds using the stick or its fingers. Their senses of sight, taste, hearing and touch are pretty much like ours. The other Great Apes (chimpanzees, bonobos and gorillas) do climb and build nests in the trees, but tend to spend their lives on the ground. It is thought that they may be the first Great Apes to become extinct unless we help to protect them. While females stay near their mothers’ home ranges during the course of their lifetimes, males may migrate long distances away from their mother’s home range. Males’ home ranges overlap with the ranges of several adult females. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons © copyright 2003-2020 Study.com. This has been attributed to mass fruit on fig trees, where groups of Sumatran Orangutans can come together to feed, not worrying about the amount of available food. Females are smaller, averaging 90 cm (3.0 ft) and 45 kg (99 lb). Take your favorite fandoms with you and never miss a beat. In Malay ‘orang’ means ‘person’ and ‘utan’ is derived from ‘hutan’, which means ‘forest’. Now imagine that is happening and you can't move to another town. After gestation of about nine months, the female builds a new nest high in a tree, where her single infant is born. When there is rain, they often make a kind of roof from branches and leaves. Orangutan infants cling to their mothers for the first one to two years of life, traveling as one through the trees and sleeping in the same nests. Some of them are being protected in five areas in Gunung Leuser National Park; others live in unprotected areas: northwest and northeast Aceh block, West Batang Toru river, East Sarulla and Sidiangkat. By doing so, they make up the deficiency of food. They are very sensitive to habitat disturbances, and in areas where even selective logging takes place, their population can drop by more than half. A survey in the Lake Toba region found only two inhabited areas, Bukit Lawang (defined as the animal sanctuary) and Gunung Leuser National Park. Fruit is the main part of a Sumatran Orangutan’s diet and figs are their favourite. Apart from fruits and leaves, orangutans also rely on aerial roots, leaf galls, epiphytic fungi, grass, orchids, stems of climbers, for their consumption. It is considered one of "The World's 25 Most Endangered Primates.". Did you know… We have over 200 college At times they also consume soil. They make a short blunt tool which they use to extract calorie-rich seeds hidden in a spiny (Neesia sp.) Also when they feel anger, but then they will add some ‘grumpfs’. Hunting of the Sumatran Orangutan still occurs as well. They eat the leaves of stinging nettles such as Dendrocnide spp. They eat the seeds of plants along with the fruit, and they then carry the seeds to other parts of the forest. About 65 – 90% of the orangutan’s diet is composed of fruits.
