[Owlchemy's Feast of Stephen](https://poal.co/s/Christmas/31847) post turned me on to this. This day, the 26th of December, is an Irish holiday. But before the Feast of Stephens was [Wren Day](https://en.wikipedia.org/wiki/Wren_Day), where the "Wren Boys" wearing straw suits, hunt a Wren and then parade around bandying their catch. There are a couple interesting theories as to how the holiday originated and what the wren symbolizes: https://en.wikipedia.org/wiki/Wren_Day#The_Celtic_Theory https://en.wikipedia.org/wiki/Wren_Day#The_Norse_theory edit: don't have time now, but here appears to be a [documentary about it](https://hooktube.com/vxASctol_8c).
