Other forms: rooks; rooked; rooking

A rook is a crow-like black bird that lives in northern Europe. To rook someone is to trick them, like a sneaky old crow. And in chess, the rook is the piece that looks like a tower or a castle.

You can tell the difference between a rook and a crow, which are both members of the bird family Corvus, by the pale skin around a rook's bill in front of its eyes and the shaggy feathers around its legs. Urban rooks, like their crow cousins, prefer areas near human activity where they can scavenge food — although they also eat earthworms and insects. You're most likely to see rooks in northern Europe, Iceland, and parts of Scandinavia (or on a chess board :) .
