  • A study conducted by researchers Mathias Osvath and Can Kabadayi,determining if ravens could plan for the future in tasks that aren't natural to the birds is presented. Planning requires the use of long-term memory for some anticipated gain down the line. For many years, it was thought to be a uniquely human trait that develops in young children. But it turned out that chimpanzees, bonobos and orangutans have this ability too, making tools to use later on. In one experiment, the ravens were trained to use a stone to dislodge some dog food from a box. Later, the birds were shown a collection of objects, including the tool, without the box in sight
