The webbed feet of swans are one reason why they can swim well. There is another reason though why swans can keep themselves floating on water even when they just sit still. Swans have body oil and they usually coat their feathers with this oil whenever they groom themselves. As most of us know, oil doesn’t mix or sink in water. That’s the secret why heavy-bodied swans don’t sink.

Fact or Fiction?
Fact!
