Interesting facts about the gray heron

  • The gray heron, also called heron or Aredea cinerea, describes a walking bird, which is widespread in Europe, Asia and Africa.
  • Depending on the distribution area, it is either a stand or migratory bird, and some populations also live as partakers.
  • Gray herons colonize different habitats from Northern Europe to South Africa, but they are missing in deserts, tundra and steppes as well as in the mountains.
  • They always stay close to waters that can be both coastal and inland. They are particularly common in shallow lakes, reed belts, ponds, swamps, lake shores and flood plains.
  • The gray heron can often be observed on beaches, in salt marshes and in mangroves.
  • Occasionally, gray herons also come into gardens when there are ponds that are populated with fish.

  • He reaches a body length of about one meter and brings a maximum weight of two kilograms on the scales.
  • Males and females do not differ in appearance.

  • With its long yellowish tweezers' beak, the gray heron is perfectly adapted to its hunting style in shallow water.
  • Its food consists mainly of small fish and amphibians as well as crabs, water snakes and newts. Also various insects, mice, rats and the eggs and chicks of other species of birds are captured.
