We humans used to think that our ability to use tools made us different from all other animals. But then we found out that chimps use tools, too, such as twigs to gather termite snacks and rocks to hammer open nuts. And some birds use tools—like brainy New Caledonian crows, which can assemble multipart tools to solve puzzle boxes presented to them by researchers.
Now we've learned that a different group of birds—seabirds—can also use tools. Scientists spied on Atlantic puffins, the distinctive tuxedoed birds with bright orange beaks. And in 2014 the observers spotted one floating on the sea off Wales, scratching its back with a stick.
Then, in 2018, the researchers caught another tool-using puffin on camera, on Iceland's Grímsey Island.

In a short video clip, a puffin can be seen grabbing a stick with its beak and then using it to scratch its chest—perhaps to dislodge one of the seabird ticks infesting the island that summer.

我们人类过去认为，使用工具的能力使我们区别于其他动物。但后来我们发现黑猩猩也能使用工具，比如用树枝收集白蚁小吃和用石头砸开坚果。有些鸟类也会使用工具，比如聪明的新喀里多尼亚乌鸦，它们能集合多种工具来解决研究人员给它们的难题箱。
现在我们知道，另一种鸟类——海鸟——也可以使用工具。科学家观察了北极海鹦，这是一种独特鸟类，其喙呈明亮的橙色，仿佛穿着燕尾服。2014年，观察人员发现，一只漂浮在威尔士海域的北极海鹦，在用棍子挠背。
之后，2018年，研究人员在冰岛格里姆西岛拍摄到另一种使用工具的海鹦。

在一个视频片段中，我们可以看到一只海鹦用嘴叼着棍子，然后用它刮擦胸部，这可能是为了弄出那年夏天在该岛泛滥的一种海鸟蜱虫。
