New Caledonian Crows craft tools for probing and prying food. They make a variety of hooked tools by first selecting the raw material, then trimming it, and finally sculpting it into a hook. They also craft a second kind of tool from the leaves of a screw pipe by alternating angled cuts with horizontal rips to create a serrated edge. They use the tools for extracting insect prey from crevices.
