The white-throated dipper (Cinclus cinclus), also known as the European dipper or just dipper, is an aquatic passerine bird found in Europe, Middle East, Central Asia and the Indian Subcontinent. The species is divided into several subspecies, based primarily on colour differences, particularly of the pectoral band.
