科学美国人60秒 SSS Atlantic Puffins Spotted Using Tools

（单词翻译）

Scientists observed two Atlantic puffins using sticks to scratch themselves—the first known instance of seabirds using tools. Christopher Intagliata reports.

We humans used to think that our ability to use tools made us different from all other animals. But then we found out that chimps¹ use tools, too, such as twigs² to gather termite³ 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 distinctive⁴ tuxedoed⁵ birds with bright orange beaks⁷. And in 2014 the observers spotted⁸ 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 beak⁶ and then using it to scratch its chest—perhaps to dislodge one of the seabird ticks infesting⁹ the island that summer. 

The details about puffin proficiency¹⁰ are in the Proceedings¹¹ of the National Academy of Sciences. [Annette L. Fayet, Erpur Sn?r Hansen and Dora Biro, Evidence of tool use in a seabird]

Study author Annette Fayet told Scientific American in an e-mail that these two instances don’t prove that seabirds are highly intelligent—though they could be smarter than we thought. But what is certain, she says, is that puffin populations are crashing, and it’s largely the fault of us and our tools—which have led to overfishing, climate change, marine¹² pollution and the presence of invasive species, all of which make seabird life harder. It would be nice to keep puffins and their compatriots around and find out just what else we don’t know that they’re capable of.
