Swan Bird

(The swan is white, the duck is white, so how to differentiate between both of them?
With the milk-water test, the swan is proven swan, the duck is proven duck!)
Hindu iconography typically shows the Mute Swan. It is wrongly supposed by many historians that the word hamsa only refers to a goose, since today swans are no longer found in India, not even in most zoos. However, ornithological checklists clearly classify several species of swans as vagrant birds in India.
