Fun thing I learned recently about the 12 days of Christmas: every gift is a type of bird. Leaping ladies, lords, all of them.
Wikipedia says "The earliest known publications of the words to The Twelve Days of Christmas were an illustrated children's book, Mirth Without Mischief, published in London in 1780" https://en.wikipedia.org/wiki/The_Twelve_Days_of_Christmas_(...
This site https://www.birdspot.co.uk/culture/the-birds-of-the-twelve-d... tries hard to link them all to birds but it's a far stretch, considering it falls apart at "Five Gold Rings". "However, Mirth and Mischief includes an illustration that clearly depicts the rings as jewelry." Archive.org even has a scan of the book: https://archive.org/details/mirth_without_mischief/page/n7/m...
