A new paper in the Royal Society's Biology Letters documents the curious tool-use of the New Caledonian crow, as reported by the CS Monitor.

Other animals, other birds, are known to use tools, but this crow is somewhat distinct in that it manufactures the tools it uses to forage for prey like larvae and insects. The tool is hook-like, usually constructed by cutting a small branch at two key points.

The team of UK researchers captured the hunting behavior of the crows by attaching tiny cameras to their tail feathers, which is how this amazing video was produced. (Click first image below to start video.)
