Watch: Crows may be smarter tool-users than chimps

Researchers have captured unprecedented footage of New Caledonian crows making and using tools in the wild. No other non-human animals—not even primates—have been seen crafting tools as sophisticated as those the crows made.

To get video of the notoriously shy creatures in the wild, scientists developed small cameras that attach to the crow’s tail feathers, a “crow-cam.” The result is a strange, crow’s-eye view of the world that researchers hope will continue to shed light on how and why the animals do what they do.
