Swan:

In ancient days, it seems a bird called swan existed. It looks like a duck but not a duck actually. The ducks behave like fools but swan does not do it. It is a very soft bird, looks so beautiful. The way it swans in water, floats in water and walks on land looks really very beautiful.
The specialty of the swans were, If we mix water and milk together and make the swan to drink it, it will drink the milk alone, leaving the water in the bowl separately. The swan has been described in many ancient epics. All the swans will be in whiter color about the possibility of separating milk which has been mixed with water. I feel even swans are imaginary creatures by man to make their story filled more loveliness. The swans are used as metaphor or smile for the kindness, loveliness and beauty for the females who come in epics.
