On the 7th Day of Christmas my true love sent to me... Seven Swans-a-Swimming A sure sign that winter is on the way is the arrival of whooper swans, which migrate to the UK from Iceland. 🦢 The patterns on their yellow and black bills are unique to each individual bird and can be used to tell them apart. They also have a honking voice which can sound like an old-fashioned car horn! #12BirdsofChristmas #12DaysofChristmas #Swans #7swansaswimming #ChristmasCarols #BirdsofInstagram #birds
