NATURA 2000 - species and habitats

The highly-endangered common kingfisher is the only member of the kingfisher family (alcedinidae) occurring in central Europe. It frequents clear, moderately fast-flowing or stagnant bodies of water with stocks of small fish on which to prey, perching on deadwood or overhanging branches. Its preferred nesting sites are nowadays rarely encountered steep erosion banks composed of finely granulated material in which it builds besting cavities 50-90 cm deep.
