In this undated photo provided by the journal Science, a wild New Caledonian crow is shown tagged with a video camera. The camera lens is protruding through the central tail feathers. Mounting tiny video cameras to the tail feathers of crows, researchers discovered that the birds use a variety of tools to seek food, and even make their own, plucking, smoothing and even bending twigs and grass stems.
