There is a Celtic myth that the robin that was supposed to represent the New Year killed the wren which represented the Old Year during this time, which might explain the origins of St Stephens Day Wren Day! #Folklore

The wran, the wran, the king of all birds,
On St. Stephen's day was caught in the furze.
His body is little but his family is great
So rise up landlady and give us a trate.
And if your trate be of the best
Your soul in heaven can find it's rest.
