During my research on 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 cohabited with other primates and with other members of its own species. My findings will support orangutan and mandrill research through first-hand observations. My observation of the orangutan habitat occurred on a sunny, warm day with an average temperature between 65-70F. The orangutan enclosure was a grassy, ​​dirt area about 35 feet wide and up and about 75 feet long with a long glass barrier for observation. The habitat included three 15-foot-tall fake trees that were modeled after a tree but had no leaves. The trees were adorned with various nets, ropes and blankets that try to imitate orangutan nests. The enclosure also included an underground or enclosed area that appeared modeled on caves; the caves were where most orangutans came and went as they hid from the sun that was directly overhead. Surrounding the enclosure was an artificial stream of running water and numerous fake bamboo sticks adorning the entire area. The enclosure is shared with 3 adult female orangutans, 1 adult male orangutan made evident by its large flanges and 1 juvenile orangutan. They also share the enclosure with 2 siamangs found in the rainforests of Borneo and Sumatra along with orangutans. One of the observable pairs was a mother and her young, which is common across the species (Cawthon), the mother mainly spent her time with her offspring and for most of the observation period remained huddled with the young in a net on a fake tree. with a blanket covering them both.... center of the card... the benefits of the zoo and how generations to come will benefit from it.
