Researchers found that two Asian elephants at a Japanese zoo sometimes blow air through their trunks to move food closer to themselves, making it easier to eat. "By blowing air through their trunks to obtain inaccessible food, the elephants appear to exhibit an advanced understanding of their physical environment," said study leader Kaori Mizuno. "Their skills to manipulate air might be related to those elephants commonly use, such as blowing for self-comfort and acoustic communication." A video of one of their experiments shows one of the elephants blowing air at a wall, in order to push some leaves closer to itself to eat. The study was published in the journal Animal Cognition. — Learn more at Discovery News
