The New Caledonian Crow

The new Caledonian crow has been observed to fashion more complicated tools into a hook shape. In the wild, they use sticks and stick it into wood or trees to get at grubs insects that are inside. And so in a lab setup, right, like they don't have access to wire in the wild, but in a laboratory setup, they do. They can make a full on hook to be able to correctly solve a puzzle by pulling up basically like a little container to help them get to a treat.
