Helsinki, Finland’s Korkeasaari Zoo is doing its best to keep its white-faced saki monkeys from getting bored. Researchers from Aalto University have set up a video monitor that allows the primates to watch a series of videos, which they say provides stimuli and improves their well-being. The researchers say it seems to have helped because there is less scratching by the monkeys. Apparently, the biggest hits were slithering worms or underwater scenes, according to cnet.com.
