The San Diego Zoo houses both orangutans (P. pygmaeus and P. abelii) and Siamangs (Symphalangus syndactylus). Through their Ape Cam live feed, we can see that exhibit is circular with a grassy center area and many tree stumps, rocks, and ropes from which to swing. Upon checking back with the live feed, the camera angle changed to a different aerial view of the enclosure, revealing the rocks more extensively. However, no orangutans or siamangs were shown. Also, I witnessed the camera pan around the large enclosure which revealed the extensive network of ropes and balls on the ropes with which the primates can play.
The next day, however, the camera revealed a view of a hammock hanging from what appeared to be a tree or some pipes. Hidden underneath some burlap in this hammock was an orangutan. The camera then switched to the ground level of the enclosure, showing the rocks and horizontal tree stumps. It also revealed one phlanged male sitting on the grass in front of the rocks, holding a burlap sack. This male proceeded to roll around the grassy area and lay down with the burlap sack on top of it. The background of this view shows a rock cave that is probably used to shelter the apes from the sun as well as give them some privacy in the enclosure from the gaze of people. Another orangutan walked into the view of the camera, picked up a burlap sack, and entered the rock cave, which then hid it from my view.
Based on these observations, the enclosure seems to have ample space for the orangutans. There also appears to be a wide variety of landscapes and terrains in the enclosure, including grassy ares, rocks, fallen trees, upright trees, a system of ropes for climbing and swinging, and the rock cave shelter. In fact, one of the hills provided an incline for one of the orangutans to roll down! However, the camera did not reveal the siamangs in this enclosure. The San Diego Zoo website reveals that there are only two siamangs present at the zoo, and including them the exhibit does seem to be ample in size. In the wild, though, the siamangs inhabit the same forests in Indonesia and Malaysia as the orangutans, so housing them together is not something strange, as they probably encounter each other in the wild.
As far as enrichment for the enclosure, there are many ropes to swing from as well as places for climbing. The rope and swing system is very extensive and quite large. The zoo website also states that in the enclosure there are two simulated termite mounds that hold snacks for the orangutans, which alternate between mustard, honey, and barbeque sauce. These termite mounds offer some enrichment, because the orangutans need to think about how to retrieve the snacks inside. Also, the burlap sacks offer enrichment as well. Bamboo near the glass viewing area provided places for the orangutans to climb as well, as one orangutan did in the live feed.
I think that this live feed is one of the best out of the other zoo feeds I’ve visited. The camera switches positions to show the orangutans very often, and upon losing sight of the orangutanss, it pans around the enclosure until they are spotted again. The website makes it very clear about how to learn more about both the orangutans and siamangs, through links at the bottom of the video. These links take you to a page with information on orangutans, as well as fun facts, facts about the orangutans, as well as facts about conservation and how the San Diego Zoo is helping to raise awareness for the dangers that orangutans face.
The Zoo Atlanta has Golden Lion Tamarins (Leontopithecus rosalia). At night, the nest cam showed the tamarins hunched over and sleeping all together in a small enclosed box. This probably is to keep the tamarins feeling safe at night. During the day, however, the camera is focused on their indoor daytime exhibit. It shows a view of several tree branches and windows, and the lion tamarins jump along these branches. There are two windows shown with sunlight streaming through them, and for a lot of the time, the lion tamarins sit on the window sills in the sun. At one point, there were four in one window, with each tamarin grooming the other. This windowsill seemed to be the area of social interactions for the group, with some jumping onto branches but always jumping back to the window sill. There appears to be no glass in the windows, though, and the tamarins appear to be disappearing through it and reappearing at the other window. So, perhaps this leads to an outside exhibit as well. My impression of the exhibit is that it is a good size for a family of about five lion tamarins, with plenty of space to move around and jump.
It seems to be that there is not much enrichment in the environment, besides the ability to play on the fairly extensive branch network in the exhibit, and also one swing made from two ropes and a bucket that is seen in the lower corner of the exhibit. The tamarins do use the swing, and jump on it for short periods, but always retreat back to the branches and window sill. There might be more that is hidden from the camera, though, since I see the tamarins disappear beyond and behind the camera’s view quite often, and there appears to be more space behind the camera as well as above and below, that is not captured. Overall, the tamarins are very active in their exhibit, and move around quite a bit.
The website provides links to learning more about the golden lion tamarin, as well as links to the golden lion tamarin conservation program in Brazil that the Zoo Atlanta partners with. It provides information on the release of tamarins from Zoo Atlanta to Brazil in the 1990’s, and how they strive to reintroduce more tamarins to the wild through their reproduction program. The website also provides clear links for donation to the conservation project.
