Summary: Researchers showed how the Eurasian jay uses metacognition to solve tricky puzzles and seek out their favorite food.

Abstract: What do you do when you’re asked a tricky question in class? Do you take a guess or wait for an easier question? The capacity to answer this question is called metacognition. It describes the ability to assess what you know and make good decisions from that information. Lots of mammals show metacognition. We wanted to know if birds do, too. We tested Eurasian jays with a food puzzle. We hid their favorite food under one of two cups. Then we moved the cups around once (easy) or three to four times (hard). The jays could take a guess at where the food was. Or they could opt out and choose their second favorite food under a third cup. Some of our jays were very successful in assessing their choices. They only chose the hard task when they knew where the food was. This means that these individuals showed metacognition! In the wild, this is important as it can help them find and store food for the winter.
