Evidence of puffins using tools suggests they’re smarter than we thought

A 10-second video captured on an Icelandic island shows an Atlantic puffin picking up a stick and scratching itself. The discovery, along with a similar observation from 2014 in Wales, is the first evidence of tool use in seabirds and suggests that seabirds like puffins may be more intelligent or possess greater problem-solving skills than we thought.
