During this season of goodwill our thoughts turn to crackling fires, being with the family and for many a song or a carol to bring merriment to the colder days. Tweet of the Day has been entertaining early morning listeners to the Radio 4 schedule every day since 2013, but this Christmas we will delight in an avian offering of the well known song Twelve Days of Christmas.

As actress Alison Steadman discusses, on the fourth day of the song, a true love is sent four calling birds. Given that most birds call, which quartet of birds could be calling? Possibly the four calling birds could refer back to colly, a derivative of the older col, roughly translated as coal. In other words, birds as black as coal. But which black bird would capture a wooing heart?
