Eurasian wren
The wren features prominently in culture. The Eurasian wren has been long considered "the king of birds" in Europe. Killing one or harassing its nest is associated with bad luck, such as broken bones, lightning strikes on homes, or injury to cattle. Wren Day, celebrated in parts of Ireland on St. Stephen's Day (26 December), features a fake wren being paraded around town on a decorative pole; up to the 20th century, real birds were hunted for this purpose. A possible origin for the tradition is revenge for the betrayal of Saint Stephen by a noisy wren when he was trying to hide from enemies in a bush.
