摘　　要：Motivational and cognitive aspects of spontaneous tool-use acquisition in species that do not do so habitually, remain an open but most relevant question. To address this, we studied captive kea (Nestor notabilis), New Zealand mountain parrots renowned for their playful cleverness. The majority of adolescent, but not the adult kea, showed a toddler-like motivation to insert objects into empty tubes and also spontaneously used objects in order to eject food from inside a tube. This parallel what is known from object exploration in large brained mammals and shows for the first time in a habitually non-tool using bird that such a technical innovation is based on object-combining acquired outside the foraging context.Motivational and cognitive aspects of spontaneous tool-use acquisition in species that do not do so habitually, remain an open but most relevant question.
