Fun facts

  • comportamientoIt is a heron of mainly nocturnal or crepuscular habits, unlike most herons, and hunts by standing still at the water's edge waiting for prey.
  • Its scientific name means literally "night raven": in flight it gives a hoarse croak reminiscent of a raven's, which is also the source of its Andalusian folk name, garza bruja, the witch heron.
  • It begins its activity just as the other herons in the colony retire to roost, which reduces competition for the feeding grounds.
  • In the Ebro delta it has been documented eating other birds, a trait more typical of American than of European populations.
