Creature: crows and their sticks

CBC is re-airing The Nature of Thing's "A Murder of Crows" this evening. It is a fascinating look at the intelligence of these birds—the New Caledonian Crow, in particular, is one of only three species (other than humans) that can make their own tools.

"Many of us have heard that crows are smart but most people have no idea just how intelligent these birds are or how much we, as humans, can learn from them. With exclusive access to a series of fascinating new research experiments being conducted into the cognitive abilities of crows around the world, A Murder of Crows will shock and amaze viewers and change how people look at the common crow."
