The common raven

A hollow "caw" makes you lift up your head (careful not to trip!). A pair of common ravens is nesting near here (they pair for life), on a cliff face. Although bigger than its cousins the carrion crow and the rook, it can be identified by its rather lozenge-shaped tail. It almost became extinct due to persecution Yet it's an omnivore and, more particularly, a scavenger which plays an important role by cleaning up disease-prone carcasses.
