These are truly majestic water birds. The white body and long white neck glide through the water. The way to differentiate it from other swans is the diagnostic color pattern of the head. The adult has an orange beak and a black face. This bird is very unusual for this area, which is why I took a picture. I saw this one in Desoto County in northern Mississippi. Last year Berry and I spotted one behind a storage building here in Memphis.
