【海鸟也能使用工具[憧憬]！#海鹦用小木棍挠痒痒#：“我很萌也很聪明”[哈哈]】Two Atlantic puffins were caught on video using small sticks to scratch themselves. A team of animal experts revealed the exciting new findings in the journal Proceedings of the National Academy of Sciences. It's the first time wild seabirds were spotted using tools. During this study of Puffin behavior, experts also ruled out doubts over the sticks being used for nesting, as puffins prefer soft materials like grass and feathers for nesting. http://t.cn/AistNrNI
