Everyone in Finland probably recognises this very familiar large, black and grey bird. In bright light the black parts of Hooded Crows’ plumage may gleam with a violet or blue metallic sheen.

The closely related Carrion Crow (C. c. corone) is the nominate race of the same species. These totally black birds, found in Central Europe, can be confused with young Rooks, though they can be distinguished by the shape of their heads and beaks, and most easily by their calls. Hooded Crows have black beaks and legs. Their irises are dark brown (mature adults) or greyish blue (juveniles).
