Corvus Corvus (Wikipedia) Corvus is a widely distributed genus of medium-sized to large birds in the family Corvidae. It includes species commonly known as crows, ravens, and rooks. The species commonly encountered in Europe are the carrion crow, hooded crow, common raven, and rook; those discovered later were named “crow” or “raven” chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for “raven”.
