Orangutans in the jungles of Sumatra have been observed carefully engineering the construction of their nests by selecting thick, sturdy branches for the scaffolding of their tree homes, and thinner, lighter branches for soft filler. The study, which appears in the journal PNAS, was done by researchers from the University of Manchester. The research was led by PhD student Adam van Casteren, who spent a year in the wild studying the creatures. Read about it here and view video of one of the primates at work.
