POINTS OF INTEREST

  • The antiquity of storks is shown by the 27 fossil species dating back some 40 million years.
  • The stork’s legendary role in human obstetrics is one of the happiest and most persistent myths in our cultural history. The stork of legend is the white stork of Europe, which has been regarded as a bird of good omen since the early Middle Ages. Their presence is regarded as such a sign of good luck that house owners frequently put platforms and baskets on their roofs in the hope that a stork will make use of them.

STATUS
Least concern. Protected in Central Europe.
