dangerous place to live when you\u2019re so big and heavy,\u201d and a poorly made nest can spell disaster, says Andrea Permana, a primatologist at the University of Warwick in England.<\/p>\n\n\n\n<p>To see how orangutans become expert canopy architects, Permana and her colleagues tracked the development of 27 young Sumatran orangutans at the Suaq Balimbing monitoring station in Sumatra, Indonesia, over 13 years. Those observations allowed the researchers to create detailed timeline of how nest building emerges. \u00a0<\/p>\n\n\n\n<p>By 6 months of age, baby orangutans take an active interest in nest building, even adding leaves and twigs to mom\u2019s nest.<\/p>\n\n\n\n<p>Young orangutans begin by building \u201cday nests\u201d \u2014 temporary platforms, often in fruit trees, for lounging while foraging. \u201cSometime before their first birthday, they\u2019ve already started to try and bend branches around in a circle to try and make a nest foundation,\u201d Permana says.<\/p>\n\n\n\n<p>At this age, they\u2019re not always strong enough to get the job done. \u201cThey\u2019ll hang on [a branch] with their body weight to try and break it, really pulling, trying to bend it,\u201d Permana says. \u201cThey think they\u2019ve made a circle and they let go and it just pings open. You can see they\u2019re kind of surprised, like \u2018Oh! It\u2019s not as easy as it looks.\u2019\u201d<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><p>\n<div class=\"youtube-embed\" data-video_id=\"_JLgvW3SgSE\"><iframe loading=\"lazy\" title=\"A baby orangutan builds a nest | Science News\" width=\"696\" height=\"392\" src=\"https:\/\/www.youtube.com\/embed\/_JLgvW3SgSE?feature=oembed&#038;enablejsapi=1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/p><figcaption class=\"wp-element-caption\">Sinta, a 1-year-old Bornean orangutan, shows off her nest building skills. Sumatran orangutans (closely related to Bornean orangutans) start learning how to build nests as early as 6 months old, a new study shows.<\/figcaption><\/figure>\n\n\n\n<p>Ages 3 to 4 are a frenzy of nest-building practice as the young orangutans perfect their day nests and try their hand at night nests. Permana recalls one young male named Fredy who, at about the age of 3, built and destroyed 21 nests in a single day. (They varied wildly in effort, quality and longevity.)<\/p>\n\n\n\n<p>By about age 5, young orangutans can build a respectable place to spend the night, usually constructing a nest a couple of meters above their mother\u2019s in the same tree. But even if they go to sleep solo, young orangutans always seem to wake up back in mom\u2019s nest until they\u2019re <a href=\"https:\/\/www.sciencenews.org\/article\/orangutans-take-motherhood-extremes-nursing-young-more-eight-years\">fully weaned at about 7 or 8 years old<\/a>, Permana found (<em>SN<\/em>: 5\/17\/17).<\/p>\n\n\n\n<p>After they\u2019ve got the nest-building basics down, the comfort features \u2014 like roofs and blankets \u2014 appear to take still more years of practice to master, appearing more frequently in nests made by adults. \u00a0<\/p>\n\n\n\n<p>Permana\u2019s study is \u201cthe first real, detailed investigation of the development of nest-building in apes,\u201d says Elizabeth Lonsdorf, a primatologist at Emory University in Atlanta. It also underscores the <a href=\"https:\/\/sumatranorangutan.org\/what-we-do\/orangutan-rescue-rehabilitation-and-reintroduction\/\" target=\"_blank\" rel=\"noopener\">important work done by forest schools,<\/a> rehabilitation facilities designed to prepare orphaned orangutans for a life in the wild by teaching them key skills \u2014 like nest building.<\/p>\n\n\n\n\n\n<p>Forest schools may need to add something a little extra to the curriculum; there\u2019s an element of culture to the bedtime routine, Permana says. Each night, every orangutan in Suaq that includes a pillow in its nest makes a special pillow-making vocalization. It\u2019s not the soulful lullaby you might expect from these mysterious, gentle giants \u2014 \u201cit\u2019s like a human blowing a raspberry.\u201d<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/sumatran-orangutan-engineering-infants\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>At six months old, human infants are still working on sitting up by themselves.
