The aim of the study is to find new ways to increase animal welfare.
High Island zoo and researchers at Aalto University have found out what kind of videos white-headed people like. The zoo and the university reported the results in a press release.
White-headed seals are small monkeys living near rainforest rivers. The first white-headed boars came to Korkeasaari in 1995, and now there are three males and four females living in the zoo.
Research For this purpose, Aalto University researchers built a tunnel-shaped box with a monitor, camera and sensors that monitor the use of space. The box was placed in the sack space in the Amazon House on Korkeasaari.
The small box of plywood was open at both ends, and the sacks were allowed to decide for themselves whether they wanted to go inside the box. If the saki went in, a weekly changing video began to spin on the screen. For the first week, the videos did not rotate.
The offerings included the underwater world, the crawling of earthworms, zebras, sweet and wild deer and their social interaction, abstract art and forest events.
The box was in use by the sacks for six weeks. During that time, sacks watched the most videos that introduced the underwater world or worms.
Tapeworms in particular seemed to be of interest to sacs. A video released by Aalto University shows how sucks are trying to lick the screen. The worm videos showed earthworms on the ground as well as worms for feeding in a white bowl.
“We found that monkeys separate things from the screen. One of the videos featured the same worms that monkeys are fed on a daily basis, and the monkeys actually tried to lick the screen as they watched and wandered behind the tunnel to see if the worms were behind it, ”says Aalto University Master’s student in the press release. Vilma Kankaanpää.
Little monkeys were least interested in following other mammals such as macaques, zebras, and roe deer.
With certainty however, according to the release, it is not possible to deduce from the results whether the interest of the sacks varied due to the content of the video. The charm of novelty can be reflected in the results.
“The sacks spent the most time watching videos in the middle of the study, when they were used to using the device but the device was still fairly new,” the release said.
During weeks three and four of the study, videos of the underwater world and the worms that sacks watched the most were shown. Last week, roe deer, sweet and zebras were shown.
Research the aim is to find new ways to increase animal welfare.
The monkeys were free to decide whether to spend their time watching the videos. Freedom of choice increases animal welfare.
“Often when technology is used with animals, for example, sounds are played without letting the animals choose what they want to listen to and whether they want to use the technology at all. It was important for us to find ways to allow ourselves to influence the environment and the use of technology, ”says the postdoctoral researcher, Aalto University Visiting Researcher Such is Hirskyj-Douglas.
The researchers found that the monkeys scratched themselves less while watching the videos. Repeated scratching is a sign of stress. Researchers in the release do not claim that stimuli directly reduce stress, but the videos offer new things for monkeys. It can increase well-being.
The results of the study were published in the scientific journal Animals.
